This invention relates to the use of vitamin K or its derivatives, alone or in combinations thereof with other active agents to increase energy levels and ameliorate disease states and life style disorders.
The invention provides novel rationale and combinations for fundamental mechanisms operated by vitamin K. The rationale provides substratum for several of the broad spectrum of activities of vitamin K serendipitously observed clinically and claimed in PCT Application PCT/IN2008/000465 which is incorporated herein by reference in its entirety. Hypoxia and energy kinetics are intimately involved in ‘cardiorespiratory fitness’ with diverse disease states and life style disorders. Enhanced energy level and oxygen utilization are central to a functional capacity.
‘Cardiorespiratory fitness’ is an integrated concept of work capacity, based on energy level, which could be compromised by effect on VO2max, substrate utilization and ATP generation.
VO2max is “the highest rate of oxygen consumption attainable during maximal or exhaustive exercise”[1]. As exercise intensity increases so also oxygen consumption increases parallel until a point where exercise intensity can continue to increase as oxygen consumption plateaus; this point is considered the VO2max.
‘Cardiorespiratory fitness’ is interchangeably described as ‘aerobic fitness’ or ‘aerobic capacity’ or ‘physical fitness’ and more technically as ‘maximal oxygen uptake’ i.e. VO2max. Cardiorespiratory fitness refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity.
Cardiorespiratory fitness improves the respiratory function by increasing the amount of oxygen that is inhaled and distributed to the body tissues, as well as its better tissue utilization and energy transduction.
Chronic and intermittent deficits in O2 supply to the body, precipitates into a variety of dysfunctions. These deficits may result even from normoxic hypoxia (low levels of oxygen in the tissue) due to microcirculation defects just as much as due to hypoxemic (low level of oxygen in the blood) hypoxia. Effective therapy needs to bring about homeostatic mechanisms that elicit corrective changes in respiratory, circulatory and energy transduction function to maintain enhanced O2 levels and/or improve the O2 affinity of the mitochondrial enzyme system for adequate generation of ATP molecules.
In the cardiorespiratory diseases there is a low level of oxygen in tissues and the blood. In eukaryotic cells, oxygen is the major source for energy. Mitochondria are the sites of cellular respiration and convert energy, through oxidative phosphorylation, into forms that are usable by the cell (i.e.) to adenosine triphoshate (ATP). Nutrients from food sources (fats, carbohydrates and proteins) are enzymatically broken down to readily utilizable substrates in the cytoplasm, in the mitochondria matrix or in both places, to generate energy.
The entry of glucose into cell and utilization of free fatty acid and their subsequent catabolism generates ATP molecules. So, during oxidative phosphorylation, electrons are transferred from electron donors to electron acceptors in redox reactions. In eukaryotes, these redox reactions are carried out by a series of protein complexes within mitochondria where oxygen acts as terminal electron acceptor. These enzymes generate ATP from adenosine diphosphate (ADP) in a phosphorylation reaction. Therefore, if there is deficiency of oxygen at cellular level, and subsequent inefficient glucose utilization and oxidative phosphorylation will result in a decrease in ATP generation and thus resulting in lower availability of energy.
The present invention relates to use of vitamin K or its derivatives, alone or in combinations thereof with other active agents which improves oxidative phosphorylation through a novel mechanism. As in many bacterial species, menaquinones (MK) function as reversible redox component of the Electron Transfer Chain (ETC), mediating electron transfer between hydrogenases and cytochromes [2, 3]. It has been observed in B. cereus that the electron flow capacity increases simultaneously with the increase in menaquinone levels and vice versa [4]. Escamilla et al [4] also observed that during early germination, NADH-dependent respiration and cytochrome reduction were restored simultaneously with a four-fold increase in menaquinone content when compared with dormant state. This means that presence of menaquinones play an important role in the electron transport chain to support ATP generation during hypoxic conditions as electron acceptor in tandem with cytochromes in prokaryotes. A similar mechanism is postulated for eukaryotes in hypoxic environments i.e. in mitochondrial site of ATP generation.
One of the highly conserved metabolic pathway is that of AMP-activated kinase (AMPK) which is today recognized as a metabolic regulator of cellular enzyme involved in the generation of ATP molecules through carbohydrate and fat metabolism.
In itself AMPK activation is governed by the increase in AMP:ATP ratio. It is well known that exercise and metabolic stress tends to increase AMP:ATP ratio. In case of exercise or metabolic stress there is prevalence of hypoxia and also in the case of ischemia.
The upstream AMPK activating enzymes as a group are called AMPK kinase or AMPKK. AMPKK activates AMPK and in-turn AMP:ATP ratio decreases by switching off ATP-consuming anabolic pathways and switching on ATP-producing catabolic pathways
A novel understanding of the mechanism of enhanced ATP generation is through the increased AMPK activation. Inventors of the present application postulate that marked amount of mitochondrial superoxide generation in the presence of vitamin K and its metabolite menadione stimulates AMPK, its upstream enzymes AMP-Activating Protein Kinase (AMPKK) and as yet undiscovered but proposed synergistic pathways to improve ATP generation. All this will result in the enhanced utilization of oxygen for energy transduction.
VO2max is routinely used to measure the cardiovascular output of athletes to assess their sports performance, of various age groups to prevent life-style related diseases (LSRD) and in many disease states to determine treatment modality.
Epidemiologic and clinical evidence demonstrate that a poor cardiorespiratory fitness is a major risk factor for life-style related diseases (LSRD) such as obesity, hypertension, hypercholesterolemia, arteriosclerosis and diabetes [5-8]. Moreover, low cardiorespiratory fitness has been found to be a predictor of cardiovascular disease (CVD) mortality, and all-cause mortality [9-12]. Thus, it is essential to maintain a high level of cardiorespiratory fitness to prevent LSRD.
Since the time of WHO Ottawa Charter of 1986 [13], a revolution has been occurring in the field of health promotion and the priorities for action needed to facilitate health for all people. The position papers disseminated by the World Health Organization (WHO) Europe Health Promotion Office, and furthered by the Ottawa Charter, the Environmentally Preferable Purchasing (EPP) Report in Canada, the Healthy Cities project, as well as other efforts, have triggered the new health promotion movement which has introduced new concepts about what constitutes health and how health promotion efforts should be configured to achieve health [14]. As a consequence, Industrial Safety and Health Law were revised in Japan in 1988. It prescribes that execution of health promotion measures for workers is an obligation of employers. In line with this, Total Health Promotion Plan (THP) was instituted [15]. THP includes not only medical examination, but also investigation of life-style and assessment of physical fitness. Determination of the maximal oxygen uptake (VO2max) is an indication of whole body endurance and is included in physical fitness assessment. Based on these results, guidance for health care and psychological counseling is provided to employees. It is reported that VO2max is influenced by life-style, such as exercise and smoking [8, 16-22]. Moreover, the preceding researches reported that the fall in VO2max is closely connected with cardiovascular system disorders, such as heart diseases, and hypertension [8, 9, 11, 12, 23-25]. Based on this evidence and from a viewpoint of preventive medicine, VO2max is being used as a health index in THP. Cardiovascular fitness is usually evaluated as the maximal oxygen uptake per body mass (VO2max mL·kg−1·min−1). The Japanese Ministry of Health Labor and Welfare in 2006 proposed VO2max reference values for each age group to prevent LSRD [26]. These VO2max reference values are referenced in the “Exercise and Physical Activity Reference Quantity for Health Promotion 2006 (EPAR2006)”. Original target, 15 years ago, was the prevention of coronary artery disease. However, following the establishment of this standard, the morbidity pattern of people has worsened and LSRD have increased in prevalence. In order to face this situation the EPAR2006 was made based on the latest scientific evidence and was designed to maintain and promote the health of people and prevent LSRD by improving their capacity for physical activity and exercise. These VO2max reference values proposed in the EPAR2006 were determined by experts through the systematic review of literature regarding the relationship between VO2max and LSRD such as obesity, hypertension, hypercholesterolemia, diabetes, cerebrovascular disease, CVD mortality and all-cause mortality.
VO2max decreases with age. The average rate of decline is generally accepted to be about 1% per year or 10% per decade after the age of 25. One large cross sectional study found the average decrease was 0.46 ml/kg/min per year in men (1.2%) and 0.54 ml/kg/min in women (1.7%) [27, 28].
Thus it becomes clear that any increase in VO2max is an increase in health level which is useful in resisting fatigue, susceptibility to stress and infection and reduction in cardiovascular fitness. It is very important to realize that higher VO2max when enhanced by physical training has underlying biochemical and molecular mechanisms. The latter can be targeted through dietary supplements etc, even without physical training. ‘Exercise in a pill’ has been reported by Narkar et al [29] suggesting that without any exercise, you can take a drug and chemically mimic it. Their earlier work reported, in a presentation at the American Society for Biochemistry and Molecular Biology, that administration of a synthetic drug 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) is now able to chemically switch on (peroxisome proliferator-activated receptor δ), PPAR-δ, the master regulator that controls the ability of cells to burn fat [30].
Several such attempts have been made, mostly to improve athletic performance. Many supplemental trials to improve VO2max have shown poor or no improvement at all. Some of them are:
1. Betaine [31]. 2. Oral phosphate loading in healthy individuals produced no improvement in aerobic capacity [32]. 3. Tricarboxylic-acid-cycle intermediates (TCAIs; pyridoxine-alpha-ketoglutarate, malate, and succinate) and other substances potentially supporting the TCA cycle (such as aspartate and glutamate) does not improve cycling performance [33]. 4. Supplementation with neither vitamin E nor C, either alone or in combination, enhanced exercise performance [34]. 5. Exercise performance is unaffected by oral supplementation with lactate [35]. 6. Supplementation of American ginseng for 4 week prior to an exhaustive aerobic treadmill running did not enhance aerobic work capacity [36]. 7. L-carnitine is unlikely to be associated with the enhanced exercise performance [37]. 8. Inosine supplementation has no effect on aerobic performance [38]. 9. Nicotinamide Adenine Dinucleotide Hydride (NADH) supplementation of 30 mg per day, in a 4 weeks' duration, balanced, double-blind, and cross-over design, had no effects on maximal oxygen uptake VO2max, maximal anaerobic running time or mental performance [39]. 10. The supplementation of chronic consumption of medium-chain triacylglycerols (MCT) neither enhances endurance nor significantly alters performance-related metabolism in trained male runners [40]. 11. Oral creatine supplementation improves exercise performance in competitive squash players [41]. 12. Creatine monohydrate supplementation did not increase performance [42].
U.S. Pat. No. 6,117,872 [43] claims administration of high levels of basic amino acids to improve physical capacity of individuals. Amino acids of choice are those that enhance vascular nitric oxide synthesis or activity to cause vasodilatation of vessels supplying exercising skeletal muscles and thereby enhancing aerobic capacity.
U.S. Pat. No. 7,071,183 [44] uses inhibitors of rennin-angiotensin system to prevent conditions associated with hypoxia or impaired metabolic function or efficiency and may be used to enhance function in healthy subjects. Whereas, U.S. Pat. No. 6,368,640 [45] provides use of a dietary supplement comprising L-arginine, alone or in combination with ginseng and Gingko biloba with other nutritional supplements to bestow sexual wellness upon a human when taken as a dietary supplement.
These various patented approaches have, in fact, been aimed at improving energy levels and thus also improved oxygen utilization.
A 1973 published study showed that in previously sedentary people, training at 75% of aerobic power, for 30 minutes, 3 times a week over 6 months increases VO2max an average of 15-20% [46]. It seems that training can slow the rate of decline in VO2max but becomes less effective after the age of about 50[47]. Recently the biochemical mechanisms leading to beneficial effects of exercise are being explored for development of new energizers. This research is being described as an “Exercise in a Pill” [29, 30].
The present invention claims supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents which enhances energy transduction processes, VO2max and cardiorespiratory fitness.
The present invention relates to the use of vitamin K or its derivatives, alone or in combinations thereof with other active agents to increase energy levels and ameliorate disease states and life style disorders.
In one aspect, the invention provides a method of alleviating hypoxemia and hypoxia, resulting in increased energy levels comprising administering to a mammal a composition of vitamin K or its derivatives alone or in combination with other active agents.
In this method, Vitamin K or its derivatives activate AMPK and is associated with (a) restoration of energy in chronic fatigue syndrome (b) countering the post-ischemic effects in heart, brain, muscles, liver and kidneys (c) increase in life-span in caloric restrictions (d) improved quality of life in patients with cancer (e) significant amelioration of metabolic syndrome (f) reduction in inflammatory cytokines and improved adipose endocrine harmony (g) relief of lipid deposition in arteries and liver and (h) increased tumor suppression.
In another aspect, the invention provides a method of improving tissue perfusion, increasing VO2max and activation of AMPK by administering to a mammal a composition of vitamin K or its derivatives, a combination of vitamin K or its derivatives alone or in a combination thereof with other active agents. Increase in VO2max influences the technical and tactical performance in all sports.

In a further aspect, the invention provides a method to lower inflammatory C-reactive protein (CRP) marker by supplementing a composition of vitamin K or its derivatives, alone or in combination thereof with other active agents. In this method, the reduction in inflammatory CRP marker is associated with reduction in atherosclerosis and thereby reduction in hypertension.
Also provided by the invention is a method of reducing normoxic hypoxia and hypoxemic hypoxia, which brings about homeostatic mechanism and maintains enhanced O2 levels and/or improve the O2 affinity of the mitochondrial enzyme system for adequate generation of ATP molecules, comprising supplementing a composition of vitamin K or its derivatives, alone or in combination thereof with other active agents.
The broad spectrum effects of vitamin K suggested that there may be one or more underlying basic mechanisms of its action. The improvement in antihypoxic function of tissues would lead to enhanced energy transduction. The fundamental mechanism for energy transduction is conventionally considered to be maximal oxygen uptake viz. VO2max.
The serendipitous clinical findings of increased energy level, less fatigue and increased endurance of muscular exertion, after administration of vitamin K2-7, suggests that there may be an important target of the vitamin, besides the known carboxylation of Glu to Gla proteins. Marked amounts of O2− (Superoxide free radical) have been reported as a consequence of the metabolism of menadione, both in guinea pig and in rat heart [48]. Menadione is a vitamin K metabolite [49]. In Staphylococcus aureus, auxotrophic for menadione, the deprivation of the latter causes a decrease in cellular levels of cytochromes, protoheme, vitamin K2 and several membrane bound flavoprotein dehydrogenases [50]. The cytochromes are maintained in the same proportion as menadione-supplemented cells. In spite of that, oxidative phosphorylation was reduced tenfold. But ATP hydrolysis is not affected. These data suggest an important role of menadione and vitamin K2 in the electron transport chain and free radical generation [50]. The post-ischemic generation of free radicals can be substantial and harmful to the cells. A flurry of superoxide flashes occurring during reoxygenation of cardiac muscle cells can be markers of diverse diseases due to oxidative stress and hypoxia etc. [51].
Vitamin K group counters these harmful effects through its diverse actions on AMP activated protein kinase (AMPK). These actions are proposed innovatively as follows:
AMP-activated protein kinase is a highly conserved sensor of cellular energy kinetics [58]. The energy homeostasis is regulated by the enzyme, whenever metabolic stress upsets it, for example in hypoxia, hyperglycemia, etc. the latter interfere with ATP synthesis. AMPK shifts the homeostasis to higher ATP generation through the catabolic pathway. Several enzymes get influenced by AMPK, which enhance energy level. The applicants propose a novel and non obvious mechanism wherein vitamin K group activates AMPK, the energy sensor. This leads to less fatigue, higher energy level and increased endurance of muscular exertion. It is claimed that vitamin K group can also serve as exercise mimetic through its effect on AMPK, which downstream works on PPARδ receptors as shown for an antagonist AICAR [29]. The clinical utility of exercise mimetic will be immense, with training or with other agents in low energy status due to diverse causes.
The benefits which accrue due to the novel use of vitamin K group is due to the results of activation of AMPK which includes but not limited to (1) Restoration of energy in chronic fatigue syndrome (2) Countering the post-ischemic effects in heart, brain, muscles, liver, kidneys etc. (3) Increase in life-span in caloric restrictions (4) Improved quality of life in patients with cancer (5) Significant amelioration of metabolic syndrome. (6) Reduction in inflammatory cytokines and improved adipose endocrine harmony (7) Relief of lipid deposition in arteries and liver and (8) Increased tumor suppression.
As several of the agents which enhance sports performance and endurance are drugs of abuse and doping has emerged as major challenge in competitive National and International sports. Hence, there is an urgent need to investigate and evolve non-addictive diet like substances which would enhance the excellence in sports without jeopardizing human health. This unmet need has been partly addressed in the present disclosure.
In otherwise healthy individual tissue hypoxia exists during endurance exercise. Hence any increase in VO2 and hypoxia are really two sides of a coin. It is convenient to determine VO2max. This is reflected in many studies referred in this document where VO2max is co-related to a variety of disease states and athletic performances.
Mortensen et al [59] examined the regulatory limits of systemic and muscle perfusion in exercising humans, and concluded, that the locomotor skeletal muscle perfusion is restricted during maximal and supramaximal whole-body exercise in association with a plateau in cardiac output and limb vascular conductance. This means that there is decrease in O2 concentration within the tissues which hampers the energy production.
Soccer players, during a soccer game, produce average exercise intensity of ˜75% to 85% of VO2max [60-64]. Helgerud et al [62] showed that an improvement in VO2max of 18 ml/kg 0.75/min and 7% reduced energy cost of sub maximal running (i.e.) improved running economy—increased both the distance covered in a game by 1800 m and the average exercise game intensity by 4% [61]. Helgerud et al [62], further showed that increased aerobic capacity is associated with 24% more involvement with the ball and a doubling of the number of sprints performed. It is recognized that aerobic capacity consists of not only VO2max but also anaerobic threshold and running economy. However, Hoff et al [63] estimate that only a small part of the game is spent at the actual intensity corresponding to anaerobic threshold.
The physical demands upon players in professional tennis have been increasing over the past few years. Tennis is a sport based on short explosive bursts of near maximal intensity (5-10 s). Resting period may vary from 10 to 20 seconds. A match may last less than one hour to as long as five hours [65, 66]. Considering partial regeneration between points as well as between matches and tournaments a high cardiorespiratory capacity may help to avoid fatigue and aid in recovery. Roetert et al [67] suggest that technical and tactical skills, psychological preparation, game strategy, motor skills such as power, strength, agility, speed, and explosiveness, and a highly developed neuromuscular coordinating ability are strongly correlated with tennis tournament performance. Nevertheless, a major determinant of the outcome of the modern game in tennis is the player's aerobic fitness (VO2max), which not only enables the player to repeatedly generate explosive strokes and complete rapid on-court movements but also ensures fast recovery and contributes to maintaining concentration and preparation for the next rally during extended play [68-70].
Furthermore activation of AMPK during exercise has been shown in various studies in the past [7]-73]. The present invention claims that vitamin K or its derivatives, alone or in combinations there of with other active agents increase activation of AMPK through a novel pathway described earlier.
The applicants claim that vitamin K or its derivatives, alone or in combinations there of with other active agents play an important role in sports medicine including but not limited to modern soccer, tennis and most other sports and has a major influence on technical performance and tactical choices. This claim is based on the fact that vitamin K or its derivatives, alone or in combinations there of with other active agents improve the tissue perfusion, increases VO2max and enhances the activation of AMPK.
There is a great concern for the older adult health, functional capacity, quality of life, and independence as by the year 2030 the number of individuals 65 yr and over will reach 70 million in the United States alone; persons 85 yr and older will be the fastest growing segment of the population [74]. Paterson et al [75] state that there is a linear decline of VO2max and functional capacity from age 30 to 65 for various measures and a greater declining rate from the age 65 onwards. However, even up to the age of 85 the ability to sustain a relatively high intensity of aerobic exercise appears preserved.
Decline and deficiency in estrogen hormone in women at menopause and during post menopausal years expose them to loss of bone mass (osteopenia/osteoporosis), weight gain and waist gain with increase in body fat percent and sarcopenia. It has been said that menopausal state is equated with metabolic syndrome. Similarly, in men andropause is characterized by increase in central obesity, sarcopenia and vulnerability for coronary artery disease. Growth hormone deficiency and low level of testosterone are implicated in this condition. Fatigue and weakness expressed as ‘low energy level’ are common complaint in menopausal women [76, 77].
Aging is a complex process but it is certain that participation in regular physical activity elicits various favorable responses that contribute to healthy aging. Aging manifests itself by decline in a number of organ functions. Participation in regular physical activity is an effective intervention. Older population adapts well to both endurance and strength exercises. One of the markers of an improved cardiovascular function is as measured by maximal VO2max. But on the other hand an improved VO2max also means a greater ability in the aerobic and endurance exercise program.
Huonker et al [78] state that, with the beginning of the 4th to 5th decade of life there is decline in the number and size of the mitochondria. Consequently the aerobic muscular energy metabolism decreases by 8-10% per decade. Hence, any nutrient that improves mitochondrial energy transduction capacity will aid geriatric population.
The instant invention claims that supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents, with or without aerobic training, enhance VO2max and thus contribute to improved health status and an increase in life expectancy in the older adult population. Such a supplement may also provide a number of psychological benefits related to preserved cognitive function, alleviation of depression symptoms and behavior, and an improved concept of personal control and self-efficacy [74].
Inventors also claim that by improvement in tissue perfusion and the activation of AMPK, can lead to the balanced homeostatic state in geriatric population.
Individuals exist who are not obese on the basis of height and weight, but who, like people with overt obesity, are hyperinsulinemic, insulin-resistant, and predisposed to type 2 diabetes, hypertriglyceridemia, and premature coronary heart disease. Such individuals are called as Metabolically Obese, Normal-Weight (MONW) individuals [79, 80]. The Third Report of the National Cholesterol Education Program Expert Panel (Adult Treatment Panel III) not only draws attention to the importance of the metabolic syndrome but also provides the first practical definition of this syndrome [81]. St-Onge et al propose that ‘individuals whose BMI is within the normal to slightly elevated range, 18.5-26.9 kg/m2, but who also fulfill the criteria for the metabolic syndrome be classified as MONW' [82].
People with the metabolic syndrome are at increased risk for developing diabetes mellitus [83] and cardiovascular disease [84] as well as increased mortality from cardiovascular disease and all causes [85]. Ford et al [86] carried out a survey to estimate the prevalence of the metabolic syndrome in the United States as defined by the ATP III report [81]. Their survey reported ˜24% of the US population had the metabolic syndrome.
One of the specific factors that appear to predispose MONW, as well as more obese individuals, is a low VO2max inclusive of insulin resistance, central fat distribution and inactivity. MONW individuals are frequently undetected and undiagnosed because of their normal BMI and young age. So there is need to identify MONW individuals and treating them with diet, exercise, and possibly pharmacological agents before these diseases become overt, or at least early after their onset.
Conus et al [87] noted that MONW women were less aerobically fit, expend fewer calories in their physical activity periods, and spent a greater portion of their time watching television. He further mentioned that, these types of biological attributes and behaviors likely contribute to the positive energy balance that leads to greater adiposity and higher total cholesterol among MONW women.
A logical next step, in terms of treatment, would be to examine the effects of mild caloric restriction and/or exercise programs to improve the metabolic profile of MONW women. The inventors have found that use of vitamin K or its derivatives, alone or in combinations there of with other active agents and vitamin K based formulations will improve the VO2max which is one of the predisposing factors in MONW and better energy transduction through AMPK activation.
By improving VO2max one enhances the ability to consume more oxygen and thus help improve the energy production, reduction in calories and ability to supply more oxygen to the cells.
The applicants in the instant disclosure claim that vitamin K or its derivatives, alone or in combinations there of with other active agents improve the tissue perfusion increase VO2max and enhance the activation of AMPK and thus helping in ameliorating the condition of MONR.
Lung cancer patient's only curative treatment is lung resection. While there is an improvement in the outcome from lung resection over the years, there is still a high rate of morbidity and mortality as a result of postoperative cardiopulmonary complications [88-90]. Out of the many postoperative cardiopulmonary complications one that has been proposed to be the best predictor of the complications after surgical resection is exercise capacity expressed as maximal oxygen consumption (VO2max).
Benzo et al [91] concluded, through a meta-analytical approach, that exercise capacity expressed as VO2max is lower in patients that develop clinically relevant complications after curative lung resection. Gaballo et al [92] state that if the maximal oxygen uptake (VO2max) is greater than 15 ml/Kg, surgery can be performed, if VO2max is less than 15 ml/Kg, patients are inoperable. Hypoxia, i.e. low oxygen availability, induces changes in transcriptional regulation that serve to alter cellular metabolism (i.e., shift to glycolytic pathways) and promote the in-growth of immature, architecturally deranged, and highly permeable blood vessels that facilitate the passage of tumor cells into the circulation [93-96]. Thus, cancer's response to hypoxia not only sustains tumor growth and survival, but through angiogenesis it fosters invasion and metastasis. Indeed, hypoxic tumors have been reported to have a predilection for tissue invasion and metastasis [97, 98]. Such adaptability has been proposed to be especially relevant in pancreatic cancer, a malignancy that exhibits a profound and characteristic avascular, hypodense appearance on contrast-enhanced computerized tomography of the abdomen [99]. Therefore there is a need to improve oxygen availability.
A common consequence of cancer and its treatment is fatigue. Aside from the psychological factors, the main physiological factors leading to fatigue in cancer patients is anemia. This lowers VO2max, which is strongly related to circulating hemoglobin. Researchers have shown that aerobic exercise training has been demonstrated to greatly relieve symptoms of fatigue in patients with cancer [100]. Schmitz et al [101] have reviewed 32 studies of controlled trials of physical activity interventions in cancer survivors during and after treatment. They conclude that physical activity improves cardiorespiratory fitness (i.e. VO2max) during and after cancer treatment.
Sawada et al [102], researching at the Tokyo Gas Health Promotion Center, studied a cohort of 9039 men (19-59 yr) who were followed for mortality between 1982 and 1988 to 1999. They concluded that low cardiorespiratory fitness (low VO2max) is associated with cancer mortality in Japanese men. Inventors of current application claim that supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents assist, with or without aerobic training, enhance VO2max and thus contribute to improved health status.
It is known that AMPK plays a restrictive role in the growth and/or survival of some cancer cells [103]. Biochemical Journal reporting research at Alessi laboratory [103] shows that AMPK activators delay the growth of tumours that occur spontaneously in PTEN (phosphatase and tensin homologue deleted on chromosome 10) heterozygous mice. The study demonstrated that the LKB1 tumour suppressor phosphorylates and activates AMPK when cellular energy levels are low, thereby suppressing tumor growth. It also suggested that mammalian homolog of target of rapamycin (mTOR), which has been implicated in the pathogenesis of insulin resistance and many types of cancer, is inhibited by AMPK.
Papandreou et al [104] reported that oxygen deprivation i.e. hypoxia can activate the autophagic pathway in human cancer cell lines. Hypoxia-induced autophagy involved the activity of AMPK. They suggested that the autophagic degradation of cellular macromolecules contributes to the energetic balance governed by AMPK, and that suppression of autophagy in transformed cells can increase both resistance to hypoxic stress and tumorigenicity. As discovered by the inventor's vitamin K supports energy transduction through multiple pathways.
Inventors of current application claims pre-post supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents helps improve outcomes in postoperative cardiopulmonary complications faced by an inevitable curative surgical lung resection for lung cancer patients and for cancer patients in general through improvements in tissue perfusion thus providing sufficient oxygen concentration and reliving hypoxia and hypoxemia. Also vitamin K enhances the activation of AMPK which can help in improving quality of life in cancer patients.
Non-insulin-dependent diabetes mellitus (NIDDM), Type 2 diabetes, is a common disease in the urban areas, globally. It is a major cause of cardiovascular disease and all-cause mortality [105-109]. Its prevalence is on the rise continuously for the last few decades [109].
Data from several prospective studies show an inverse association between physical activity and diabetes [5]. Physical work capacity (VO2max) is strongly associated with insulin sensitivity of skeletal muscle and subcutaneous adipose tissue [110]. First-degree relatives of type 2 diabetic patients (offspring) are often characterized by insulin resistance and reduced physical fitness (VO2max) [111]. The role of lifestyle intervention in preventing development of Type 2 diabetes has been explored in several trials during recent years, and there is now a vast body of evidence demonstrating that physical activity often in combination with weight loss causes a considerable reduction in the risk of developing Type 2 diabetes [111].
Poor physical fitness is a strong indicator of an increased risk of developing diabetes. The cause of decreased VO2max in Type 2 diabetic subjects and their relatives has not yet been fully determined.
Inadequate tissue perfusion leads to the inadequate oxygen concentration within the tissues resulting in development of hypoxia. Matsumoto et al [112] in their review on disturbance of microcirculation due to unhealthy lifestyle, hypothesize that unhealthy lifestyle first causes disturbance of the microcirculation, prompting opening of arteriovenous shunts and increasing bypassing of blood. This prevents the delivery of glucose and insulin to cells of peripheral tissues, causing apparent reduction of insulin sensitivity. Disturbance of the microcirculation also causes oxidative stress in peripheral tissues by inducing ischemia and hypoxia. This oxidative stress is considered to further exacerbate reduction of insulin sensitivity.
O'Donnell et al. [113] in his study on the metabolic consequences of intermittent hypoxia in mice, shows that in lean, otherwise healthy mice, exposure to intermittent hypoxia produced whole-body insulin resistance and reduced glucose utilization in oxidative muscle fibers. They conclude that intermittent hypoxia can cause acute insulin resistance in otherwise lean healthy animals, and this response is not dependent on the activation of the autonomic nervous system.
Polotsky et al [114] and group in yet another study on genetically obese mice shows that obese mice exposed to intermittent hypoxia for 12 weeks (long term) developed a time dependent increase in fasting serum insulin levels and worsening glucose tolerance, consistent with an increase in insulin resistance.
Eriksson et al [115] studied non-diabetic 4637 men between the ages of 48 to 54. Physical fitness was measured in terms of lung vital capacity and oxygen uptake during ergometry. Those who developed NIDDM were found to have 16% lower mean estimated maximal oxygen uptake along with deterioration in other parameters. Similarly, Regensteiner et al [116], in a trial with controls showed that at maximal exercise, diabetic persons had a 24% lower maximal walking time and 20% lower maximal VO2 than controls (both P<0.05), while hemodynamic measures did not differ between groups. During graded exercise, at work loads below the maximal one, the relationship between VO2 and work load was significantly lower in persons with NIDDM than controls by an average of 16%. They suggest that limitations in oxygen delivery may impair exercise performance in otherwise healthy persons with diabetes [116].
In yet another trial with 255 patients over a period of 10 years a low maximal oxygen uptake (VO2max) was found in patients with NIDDM compared with sedentary control subjects. In 29% of the patients there were also higher blood pressure levels at rest and during exercise with impaired VO2max. At the end of the program the researchers conclude the importance of aerobic fitness for the patients with NIDDM [117].
The reduced rate of increase in oxygen consumption during increasing sub maximal work loads in NIDDM suggests that limitations in oxygen delivery may impair exercise performance in otherwise healthy persons with diabetes [116].
Persons with type II diabetes mellitus (DM), even without cardiovascular complications have decreased maximal oxygen consumption (VO2max) and sub maximal oxygen consumption (VO2) during graded exercise compared with healthy controls [118].
Hyperinsulinimia and decrease in insulin sensitivity (insulin resistance) precedes NIDDM and even pre-diabetic conditions like Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT) in obesity, Polycystic Ovarian Syndrome (PCOS), menopause, aging, etc.
Prevalence of hyperinsulinimia and insulin resistance is 60-70% in women with PCOS. Metabolic Syndrome and/or insulin resistance are reported 16-50% in menopausal women [119, 120].
Women with PCOS have associated metabolic dysfunction like dyslipidimia, high triglycerides and low HDL, dysglycemia hypertension etc., due to impaired insulin action in presence of hyperinsulininemia. It has been suggested that though insulin's metabolic action is defective in these patients, their mitotic function is intact. This causes proliferative disease at various sites like capillaries, ovarian stroma, uterine endometrium and acanthosis nigricans (thickening and darkening of the skin).
Eriksson et al [121], in a 15-year follow-up study, concluded that Increased skeletal muscle capillary density precedes diabetes development in men with impaired glucose tolerance. They suggest that the increased circulating insulin concentrations in IGT (impaired glucose tolerance) subjects have a capillary proliferative effect, perhaps to compensate for reduced capillary insulin diffusion and metabolic capacity of the muscle. These results suggest that diffusion distance from capillary to muscle cells or some associated biochemical change, and fiber type, could play a role in determining in vivo insulin action [122].
Yoshida et al [123], in a 36-month, randomized, double-blind, controlled trial with vitamin K supplementation of 500 μg/day showed a reduction in progression of insulin resistance in older men. However, no attempt was made to study the differences in the energy levels of the control and the interventional groups despite the long duration of the study. Inventors have proposed that the activation of the AMPK, and down stream effects on insulin action such as AKT phosphorylation and Glut4 translocation play a role in the clinical demonstration of retarded progression of insulin resistance in the trial.
AMPK is considered as a master switch in regulating glucose and lipid metabolism and that, as claimed, vitamin K stimulates AMPK status.
Winder et al [124] states that the net effect of AMPK activation is stimulation of hepatic fatty acid oxidation and ketogenesis, inhibition of cholesterol synthesis, lipogenesis, and triglyceride synthesis, inhibition of adipocyte lipolysis and lipogenesis, stimulation of skeletal muscle fatty acid oxidation and muscle glucose uptake, and modulation of insulin secretion by pancreatic beta-cells. The aforesaid changes contribute to the induction of Non-Alcoholic Fatty Liver Disease (NAFLD). Inventors propose that AMPK activation by the vitamin K or its derivatives, alone or in combinations there of with other active agents alleviate the syndrome.
In skeletal muscle, AMPK is activated by contraction [124]. However, defects or disuse (due to a sedentary life style) of the AMPK signaling system would be predicted to result in many of the metabolic perturbations observed in Type 2 diabetes mellitus. They further mentioned that increased recruitment of the AMPK signaling system may be effective in correcting insulin resistance in patients with forms of impaired glucose tolerance and Type 2 diabetes resulting from defects in the insulin signaling cascade.
Misra et al [125] state that along with evidence from studies showing that chemical activation of AMPK in vivo with 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) improves blood glucose concentrations.
We claim that supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents to humans to reduce significant risk factor of the physical work capacity (VO2max) in diabetic patients and their first degree relatives. We claim that increased tissue perfusion and reduction of hypoxia and hypoxemia with supplementation of vitamin K, as claimed in applicant's earlier patent application PCT/IN2008/000465 incorporated herein by reference, enhances the activation of AMPK ameliorating progression of insulin resistance and NIDDM.
Inadequate tissue perfusion causes impairment in microcirculation which leads to the deprivation of necessary nutrients and oxygen resulting in the damage to the myocardium and other parts of heart. This in turn increases all causes of morbidity and mortality.
Sanchez et al [126] state that “ . . . Maximal exercise performance in patients with chronic heart failure, as determined by peak oxygen consumption (VO2max) during exercise testing has been shown to correlate well with mortality.'.
Blair et al [12] conducted a large study, at the Cooper Institute for Aerobic Research, Dallas, wherein there were 25341 men and 7080 women participants who completed preventive medical examinations, including a maximal exercise test, with a view to determine influence of VO2max and other precursors on CVD and all-cause mortality in men and women. Their findings bring forth importance VO2max. Low VO2max is a predictor of premature mortality. Further publications, from the same study group reinforce earlier findings and add clarity 1. A maximal exercise test (VO2max) performed in asymptomatic men free of cardiovascular disease does appear to be a worthwhile tool in predicting future risk of CHD”[23] 2. Low cardiorespiratory fitness (low VO2max) and physical inactivity are independent predictors of all-cause mortality in men with type 2 diabetes [25].
Lakka et al [8], in their study, find that “good cardiorespiratory fitness (VO2max) is associated with slower progression of early atherosclerosis in middle-aged men”.
Information from these studies allowed further studies to be more focused and concluded that “Cardiorespiratory fitness (VO2max) had a strong, graded, inverse association with overall, CVD-related, and non-CVD-related mortality. Maximal oxygen uptake (VO2max) and exercise test duration represent the strongest predictors of mortality”. Weisman, researching at William Beaumont Army Medical Center, El Paso, Tex., comes to the same conclusion on the importance of VO2max [127].
Sedentary life style i.e. low physical activity has a negative influence on blood pressure and cholesterol, and may lead to diabetes. The study conducted by University of Hong Kong [128] states that the sedentary lifestyle is more dangerous for health than smoking. They reported that the 20% of all deaths of people 35 yrs and older were attributed to a lack of physical activity. They further mentioned that the risk of dying from heart disease was 52% higher for men and 28% higher for women, all due to a lack of physical activity.
Vermeer [129], in his patent application claims use of vitamin K and its derivatives to recover elasticity of the age-related stiffening of the arteries. His claim is for the useful role of vitamin K in reducing and reversing medial calcification of coronary artery and subsequent improvement in myocardial perfusion. To achieve this, Vermeer claims the treatment period lasting 6 months to 36 months with the ideal period as 36 months. Inventors of the current patent application do not claim their novel discovery based on the decalcification and nor do they wait for the decalcification. Inventors claim early benefits within a much shorter period of 30 days to 6 months and optimally a period of 2 months.
Also, the energy transduction improvement claimed in the current invention at the mitochondrial level is a novel, non-obvious and very useful in a coronary artery disease, improving myocardial inotropic action.
Invention is additionally enhanced by the use of the novel derivatives and combinations which synergize the energy transduction as well as myocardial cell contractibility. The latter would increase ionotropism and myocardial ejection function.
Li et al [130] in their review article have mentioned that adiponectin activates AMPK phosphorylation and then promotes various ATP-generating pathways in heart. They also stated that phosphorylation of AMPK induced by adiponectin inhibits myocardial protein synthesis, and would diminish the pathological cardiac hypertrophy. AMPK activation also has a cardioprotective role against myocardial injury and apoptosis in the ischemic heart. Son et al [131] demonstrated that adiponectin also antagonizes the stimulatory effect of TNF-alpha on the vascular damage by restoration of the AMPK-dependent Gas6-mediated survival pathway. This study clearly shows that the AMPK activation has a significant role in antagonizing chronic inflammation and hence has anti-atherosclerotic effects.
Hence, as mentioned above, inventors are claiming that the result of improving VO2max and enhancing AMPK activity i.e. enhancing the ability to consume more oxygen and to improve the energy production, and ability to supply more oxygen to the cells results in the amelioration of the coronary artery diseases.
Essential hypertension is pandemic throughout the world. There is marked increase in risk of developing numerous cardiovascular and respiratory complications with hypertension.
Current treatment modalities emphasize the role of non-pharmacological interventions and physical activity besides a wide spectrum of drugs. Many studies [7, 132-142] have firmly established that the regular exercise reduces the incidence of hypertension [7, 132-142].
Karch et al [143] evaluated the coronary capillary density by histological examination of the myocardium in four types of patients: control individuals, patients with ischaemic heart disease, inflammatory heart disease, or a dilated cardiomyopathy. Using computerized image analysis, precise modelling of the role of each capillary within a tissue unit is now possible. The tissue areas perfused by each capillary thus overlap in a healthy individual, thereby ensuring optimum oxygenation and nutrition of the tissues. In contrast, during ischaemic, inflammatory or dilated heart disease and during hypertension, capillaries are separated by greater distances, and the tissue area dependent on each capillary unit is greater so that certain areas of the myocardium are perfused poorly or not at all.
Hagberg. et al [135] in his study on the effect of exercise training on essential hypertension, has shown that endurance exercise training reduces systolic and diastolic blood pressures in approximately 75% of people who have essential hypertension. These reductions were approximately 10 mmHg for both systolic and diastolic blood pressures.
Iwane et al [137] investigated the effect of walking 10,000 steps/day or more on blood pressure in mild essential hypertensive patients, had found that, irrespective of exercise intensity or duration walking 10,000 steps/day or more was effective in lowering blood pressure in hypertensive patients and VO2max rose significantly.
Sawada et al [7] in his five years prospective study for finding out the relation between physical fitness (VO2max) and incidence of hypertension in cohort of 16,525 out of which 425 subject were diagnosed as hypertensive in the fifth year, shows that low VO2max level is related to the higher incidence of hypertension.
Mughal et al [141] studied the effect of aerobic exercise on changes in blood pressure and VO2max. They concluded that brisk walking yielded significant increase in VO2max (P<0.05).
Quinn et al [142] studied the effect of mild to moderate acute, endurance exercise in hypertensive individuals. They found that an exercise bout conducted between 50-75% VO2max significantly decreases systolic blood pressure and diastolic blood pressure in hypertensive subjects and that a greater and longer-lasting absolute reduction for 11 hrs after 75% bout compared to 4 hrs after 50% intensity.
Atherosclerosis is the basic lesion aggravating hypertension and its complications. Further atherosclerosis can impair the ability of skeletal muscle to utilize O2 i.e. affecting cardiovascular fitness. In atherosclerosis elevated C-reactive protein (CRP) is a major risk factor. Kuo et at [139] examined 1438 adults aged 20-49 years for C-reactive protein (CRP) and VO2max. They found that CRP levels, inversely related to VO2max. Both lower CRP and higher VO2max are important indicators of exercise tolerance and cardiorespiratory fitness. Available literature, including patent literature [129] suggests calcification as a putative risk factor for cardiovascular disease as well as for hypertension. However the available data, by vitamin K supplementation, and animal models and other wise is for prevention of calcification but not for reverse. Hence reversal of calcification is postulated as a mechanism for lowering hypertension. These inventors have not claimed that lowering of CRP and improvement in VO2max are the activities of vitamin K. Unlike that, the present inventors have proposed a novel mechanism with the effect of vitamin K on energy transduction with cardiovascular protective action against diverse risk factors in hypertension and coronary artery disease.
Here the inventors claim that use of vitamin K or its derivatives, alone or in combinations thereof with other active agents and vitamin K based formulations improves tissue perfusion, improvement in VO2max, and enhances the activation of AMPK.
The applicants, in the current disclosure claim supplementation of vitamin K or its derivatives, alone or in combinations there of with other active agents and vitamin K containing formulation reduces inflammatory marker CRP and consequences thereof.

Male, 32 years, with high moderate fitness, kept on mix of cardiovascular and resistance training exercise for 3-5 hrs per week, along with 3 capsules per day of MyoMax™ containing 450 μg of vitamin K2-7, for 2 weeks. Capsule was taken p.o. after baseline VO2max done which was 44.4 ml/kg/min. Within 2 weeks his VO2max changed from 44.4 ml/kg/min to 53.5 ml/kg/min. The observed percentage of increment was about 17%.
Male, 41 years, with High moderate fitness, kept on exercise for less than 3 hrs per week, for 2 weeks, along with 6 capsules per day of MyoMax™ containing 750 μg of vitamin K2-7, taken just for 4 days. Capsule was taken p.o. after baseline VO2max done which were 48.6 ml/kg/min. His VO2max changes from 48.6 ml/kg/min to 82.0 ml/kg/min within 2 weeks. The observed percentage of increment was about 41%.
Male, aged 68 years with hypercholesterolemia (Lipid Profile; 200 mg—Total cholesterol) for which he is taking Atorvastatin 5 mg one per day and 75 mg of Aspirin one per/day since last five years. At the age of 64 underwent angioplasty. He was also having blood pressure which ranges from 136-134/90-88 mmHg. He was taking Telmisartan 40 mg/day from last 4 years for hypertension. Then about 6 months ago he started taking vitamin K2-7 in daily dose of 200 μg. Currently he has stopped taking anti-hypertensive medication from last 1 month. Over a period of 1 and ½ months it is observed that his blood pressure has dropped down to 118-114/78-84 mmHg. Now he is off any anti-hypertensive medicine and continues with vitamin K2-7 only.
Female, aged 50 years suffering from general fatigue. She used to go to Gold gym 5-6 times per month. On the treadmill she used to walk at 5 km/hr speed at the start of the exercise and then gradually increase it to 6 km/hr in the next 15 minutes. When she started taking vitamin K2-7 350 μg per day, within 2 weeks of taking vitamin K2-7, she could start at 6 km/hr and go on up to 6.4 km/hr on the treadmill without feeling the strain she felt earlier. Her general fatigue had reduced. Her treadmill experience, was now smooth and ‘effortless’.
Woman aged 63, was diagnosed to have bilateral ovarian cancer in 2005, with ascites and abdominal lymph node metastases. She has undergone surgery and several courses of chemotherapy. Despite that she had a recurrence in June 2007 and subsequently lesions in liver in June 2008. She is currently under chemotherapy cycles. She tolerated chemotherapy reasonably well but complained of marked fatigue and low energy levels. She was started with vitamin K2-7, 100 μg. per day which gave her not much relief in fatigue and energy level. She was given a larger dose of vitamin K2-7 per day. Within six weeks, she reported a sense of well-being, less fatigue and significant improvement in the energy level. She is continued on the dose of vitamin K2-7 for two months. Her complaint of post-chemo restlessness/akathisia did not benefit from vitamin K2-7, but was relieved by phenergan. Her CEA levels have dropped markedly.
Male aged 72, had a history of subendocardial infarct (15 years back), hypertension and reasonably controlled moderate diabetes mellitus. His complaints were fatigue, low energy level, muscle cramps and tingling and numbness of lower limbs. The symptoms of the nerves and muscle were significantly relieved with vitamin K2-7 100 μg per day. These returned with drawal and were relieved with re-therapy. However the fatigue and low energy levels were only mildly relieved. He was started 350 μg per day of vitamin K2-7 over the two months period. He (a physician) has noted significant relief in fatigue and reasonable increases in the energy level. His cramps and neuropathic symptoms continue to be markedly reduced. There were no side effects with MK-7.
Male aged 56 yrs was having hypertension (160/114 mmHg) but was not on any medication. He complained of fatigue and low energy level. He was put on 3 capsules per day of 100 μg of vitamin K2-7 for 1 month and then on 2 capsule per day of 350 μg of vitamin K2-7 for the next 2 months under close observation by medical doctor. He showed decrease in systolic blood pressure (140/108 mmHg). He continued the medicine for next couple of month with same dose i.e. 2 capsules per day of 350 μg of vitamin K2-7. The blood pressure showed further drop to 138/104 mmHg. Then he was taken off from the treatment for 15 days. Blood pressure shot up to 146/108 mmHg, He was again put on vitamin K2-7, 350 μg, 2 capsules per day and his blood pressure came down to 136/100 mmHg. He also feels improvement in fatigue and feels more energetic at work.
Male aged 49, healthy otherwise, was having blood pressure on higher side i.e. 130/90 mmHg. He was advised to start taking vitamin K2-7, in a dose of 650 μg, one capsule per day. After 2 months of drug intake, blood pressure showed marked reduction to 112/80 mmHg. There were no adverse effects noted in the period of the treatment.
Male aged 56 yrs, was heaving history of Spondylosis, Diabetes mellitus and Hypertension. Five years ago he was operated for cataract (right eye). He is on regular medicine i.e. Atenol50™, one per day, after breakfast, Insulin2™ one per day after lunch, and Diaonil5™, two times a day. He was complaining of fatigue and lack of energy so much so that he found ascending 20 steps at a time difficult with related exhaustion and breathlessness. He was advised to take vitamin K2-7, 350 μg, one cap per day. After a month of time he started feeling more energetic and would walk up the stairs easily without any problem.
Four participants of age ranging from 32 to 40 yrs of both the sex were enrolled in a study where change in VO2max was studied with subsequent change in VO2, upon administration of vitamin K2-7. All the participants were trained athletes and so any change in VO2 was very interesting as the better trained one was, the harder it was to increase VO2max. VO2 was measured at AB (Aerobic Base) and at AT (Anaerobic Threshold). VO2max was measured at AT (Anaerobic Threshold). All patients were given 600 μg per day, 300 μg in the morning and 300 μg in the evening of vitamin K2-7 for 21 days.
Table 2 shows the demographic data of participants.
After 21 days of treatment there were significant increases of VO2 at AB when compared to VO2max. There was significant increase of oxygen carrying at AB and AT. Also, heart rates at AB and AT increased significantly as well. An overall increase in AB, AT and VO2max shows a significant increase in cardiovascular fitness.
As shown in Table 3 (a) and (b) there was average increase in VO2 at AB was 8 mL/Kg/min and VO2 at AT was 6.75 mL/Kg/min as compared to baseline.
From an athletic performance standpoint, VO2 at AB and AT are actually more important as work (in watts) was done at AB and AT heart rates. The more VO2 at AB and AT, the more watts of work one can perform at those points.
AB is where one is at the optimum aerobic/mitochondrial respiration. Body uses O2 as the primary electron acceptor and burning fat for energy. The higher the AB, the faster, longer and harder work can be performed. Increasing VO2 at AB is important and signifies improvement in cardiovascular fitness.
AT is where the body begins to switch to mostly anaerobic respiration. The higher the VO2 at AT the more work can be done and the longer one can sustain that work at their AT. In Table 4, VO2max shows increasing trend from baseline. The average increase at this point is of 5 mL/Kg/min, which is significant. This was again very interesting finding as any improvement in VO2 max translates to improvement in cardiovascular fitness.
Table 5 (a) and (b) show the improvement in beats per minute (bpm) at AB and AT after treatment with vitamin K2-7.
Overall increase in VO2 also increases AB and AT heart rate. Increasing AB and AT is a milestone in cardiovascular training for athletes. For non-athletes, increasing AB and AT is a mark of increased cardiovascular fitness.
Vitamin K2-7 appears to achieve this by the hypothesized mechanism proposed earlier. These results indicate that there was not only improvement in maximum oxygen utilization but also in the utilization of oxygen at both aerobic base and at aerobic threshold. There was also a marked improvement in the AB and AT heart rate. This all findings points toward the novel mechanism of action of vitamin K2-7 in the cardiovascular fitness.
