The present invention generally relates to compositions and methods for supporting exercise performance or activities of daily living. The compositions described herein are pharmaceutical or nutritional compositions suitable for enhancing exercise performance. The compositions are based on a specially formulated mixture of essential amino acids (EAAs) with additional components. The compositions target support of muscle protein synthesis and reduction of muscle breakdown during exercise, increasing muscle blood flow during exercise, decreasing the perception of fatigue by supporting optimal availability of neurotransmitter precursors, providing energy for rapids bursts of exertion during exercise, and maintaining adequate electrolyte balance during exercise.
Muscle protein is in a constant state of turnover, meaning muscle protein is being broken down and synthesized continuously. Exercise workouts are undertaken to improve muscle performance. Regardless of the nature of the exercise workout, the principle physiological mechanism underlying improvements in muscle function and muscle size is the balance between muscle protein synthesis and muscle protein breakdown. Exercise causes an increase in blood flow to the muscle, which in essence “flushes out” intracellular essential amino acids (EAAs) into the blood. When concentrations of EAAs inside the muscle cells are lowered, the rate of muscle protein breakdown is increased. In addition, intracellular EAAs serve as precursors for the synthesis of new muscle protein. As the muscle EAAs are flushed from the intracellular fluid to the blood, there are fewer EAAs available for reincorporation into muscle protein via protein synthesis. The impaired ability of muscle protein synthesis to keep pace with muscle protein breakdown during exercise is also due to an increased oxidation of certain (but not all) EAAs. Some of the EAAs released in the process of muscle protein breakdown are oxidized to produce the energy needed to support muscle contraction. Once EAAs are oxidized, they are not available to be reincorporated into muscle protein.
Leucine is the most abundant EAA in muscle and also can play a role as a “nutraceutical”, meaning that in addition to its role as a precursor for protein synthesis it also serves as a signal to the molecular mechanisms in muscle cells that are involved in the initiation of protein synthesis. Consequently, leucine availability can become rate limiting in terms of the synthesis of muscle protein during exercise. For example, even just light exercise causes a 4-fold increase in leucine oxidation, while the oxidation of other EAAs such as lysine and phenylalanine do not increase. The disparate rate of oxidation of different EAAs reduces leucine concentration in blood, creating an imbalance in EAA concentrations in the blood. Leucine depletion in the blood during exercise not only decreases synthesis of new muscle proteins, but also induces the perception of fatigue. Tryptophan, the precursor to serotonin, and leucine are structurally similar and compete for the same transporter for entry into the brain. When the blood concentration of leucine falls relative to tryptophan concentration during prolonged aerobic exercise, more tryptophan enters the brain and the amount of serotonin is increased. An increase of brain serotonin during exercise can decrease mental focus, giving the perception of fatigue even when physical capacity is not limited.
The notion that leucine can be rate limiting during exercise has led to the popularity of dietary supplements of leucine or the branched chain amino acids (BCAAs) leucine, isoleucine and valine. However, provision of these supplements has proven ineffective in stimulating muscle protein synthesis, during exercise or in any other circumstance. In addition, increased BCAA levels only slightly improve mental focus. This is because an increase in BCAAs will not only decrease tryptophan uptake by the brain, but also limit the uptake of phenylalanine. Phenylalanine is the precursor for the synthesis of dopamine, which is the principal excitatory neurotransmitter in the brain. Mental focus and alertness is the result of the balance between dopamine and serotonin in the brain. Consequently, an EAA formulation with abundant BCAAs as well as phenlyalanine will most effectively enhance mental focus during exercise. Therefore, there is a need in the art for compositions comprising a unique combination of ingredients for improving exercise performance, wherein the combination of ingredients accounts for the disparate rates of oxidation of different EAAs and promotes mental focus during exercise. Such compositions can result in an increase in muscle protein synthesis and a reduction of muscle protein breakdown during and immediately following exercise, ultimately increasing muscle mass, muscle strength, and muscle function, and can also improve exercise performance by reducing the perception of fatigue.
Error bars represent standard error of mean (SE) where a p value<0.05 was significant as assessed via ANOVA.

The following examples are included to demonstrate various embodiments of the present disclosure. It should be appreciated by those of skill in the art that the techniques disclosed in the examples that follow represent techniques discovered by the inventors to function well in the practice of the invention, and thus can be considered to constitute preferred modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention.
EXAMPLE 1. Six normal untrained men were studied during the intravenous infusion of a balanced amino acid mixture (approximately 0.15 g·kg−1·h−1 for 3 hours) at rest and after a leg resistance exercise routine to test the influence of exercise on the regulation of muscle protein kinetics by hyperaminoacidemia. Leg muscle protein kinetics and transport of selected amino acids (alanine, phenylalanine, leucine, and lysine) were isotopically determined using a model based on arteriovenous blood samples and muscle biopsy. The intravenous amino acid infusion resulted in comparable increases in arterial amino acid concentrations at rest and after exercise, whereas leg blood flow was 64 ±5% greater after exercise than at rest. During hyperaminoacidemia, the increases in amino acid transport above basal were 30%-100% greater after exercise than at rest. Increases in muscle protein synthesis were also greater after exercise than at rest (291 ±42% vs. 141 ±45%) (
EXAMPLE 2. To determine the effects of prolonged aerobic exercise (approximately 30% VO2 max for 105 min) on the oxidation of three different EAAs in human subjects, primed constant infusion of either (1) [1-13C]leucine, (2) α-[15N] lysine, or (3) [2H5] phenylalanine plus [2H4]tyrosine was performed using the same methods previously described in Wolfe et al., J A
EXAMPLE 3. Six healthy untrained subjects received a primed constant infusion of L-[2H5]phenylalanine and L-[1-13C]leucine. Next, the subjects performed resistance exercises for about 40 minutes. Subjects received a dose of 6 grams of orally administered essential amino acids (EAAs) 1 hour after resistance exercise followed by another of dose of 6 grams of EAAs 2 hours after resistance exercise. Blood samples from the femoral artery and vein in addition to biopsies from vastus lateralis muscle were collected at 30, 70, 80, 90, 105, 130, 140, 150, 165, 180, 210, 220, and 240 minutes after completion of the resistance exercise regimen. Arterial EAA concentrations increased several-fold after each EAA dose where the EAA concentration a t=30 minutes was used at the baseline measurement. Because phenylalanine is neither produced nor metabolized in muscle, net phenylalanine balance reflects net muscle protein synthesis, provided there are no significant changes in the free intracellular pool of phenylalanine. As such, net muscle protein balance (NB) was calculated as follows: (phenylalanine arterial concentration−phenylalanine venous concentration)×blood flow. NB increased proportionally more than arterial EAA concentration in response to each EAA dose. NB returned rapidly to basal values when arterial EAA concentrations decreased. Area under the curve for net phenylalanine uptake above basal value was similar for the first hour after each EAA dose (67±17 mg/leg vs. 77±20 mg/leg, respectively) (
Six healthy untrained subjects received a primed constant infusion of L-[2H5]phenylalanine and L-[1-−13C]leucine. Next, the subjects performed resistance exercises for about 40 minutes. Subjects received either: (1) a dose of 6 grams of orally administered essential amino acids (EAAs) 1 hour after resistance exercise followed by another of dose of 6 grams of EAAs 2 hours after resistance exercise; (2) a dose of 3 grams of orally administered essential amino acids (EAAs) 1 hour after resistance exercise followed by another of dose of 3 grams of EAAs 2 hours after resistance exercise; or (3) a dose of 20 grams of whey protein 1 hour after resistance exercise. Blood samples from the femoral artery and vein in addition to biopsies from vastus lateralis muscle were collected at 30, 70, 80, 90, 105, 130, 140, 150, 165, and 180 minutes after completion of the resistance exercise regimen. NB was calculated from samples to determine total net muscle protein synthesis over 3 hours post exercise. Total net muscle protein synthesis following 2 doses of 6 grams of EAAs was almost double total net muscle protein synthesis following 2 doses of 3 grams of EAAs and whey protein (
EXAMPLE 4. This study was designed to determine whether consumption of an oral essential amino acid-carbohydrate supplement (EAC) before exercise resulted in a greater anabolic response than supplementation after resistance exercise. Six healthy human subjects participated in two trials in random order, PRE (EAC consumed immediately before exercise), and POST (EAC consumed immediately after exercise). A primed, continuous infusion of L-[ring-2H5]phenylalanine, femoral arteriovenous catheterization, and muscle biopsies from the vastus lateralis were used to determine phenylalanine concentrations, enrichments, and net uptake across the leg. Blood and muscle phenylalanine concentrations were increased by approximately 130% after drink consumption in both trials. Amino acid delivery to the leg was increased during exercise and remained elevated for the 2 hours after exercise in both trials. Delivery of amino acids (amino acid concentration times blood flow) was significantly greater in PRE than in POST during the exercise bout and in the 1st hour after exercise (where p<0.05 was considered significant). Total net phenylalanine uptake across the leg (direct reflection of net muscle protein synthesis) was greater (p=0.0002) during PRE (209±42 mg) than during POST (81±19) (
EXAMPLE 5. A kinetic study with a stable isotope tracer method was performed to determine in vivo kinetics of nitric oxide (NO) metabolism in relation to citrulline ingestion in older adult humans (n=8, 77±9 years, 93±4 kg) and in young adult humans (n=8, 27±9 years, 70±5 kg). In the fasted state, NO synthesis (expressed per kg fat free mass) was ˜50% lower in older vs. young adults and was related to a decreased rate of appearance of the NO precursor arginine. Citrulline ingestion (3 grams) stimulated de novo arginine synthesis in both older (6.88±0.83 to 35.40±4.90 μmol·kg body wt−1·h−1) and, to a greater extent, in young adults (12.02±1.01 to 66.26±4.79 μmol·kg body wt−1h−1) over 3 hours (
EXAMPLE 6. Eight subjects were given an oral dose of 11 g of EAAs, excluding tryptophan. Changes in plasma leucine concentration were monitored over time in subjects for up to 240 minutes following administration of EAAs, excluding tryptophan. Data indicated that the EAA dosage caused a more than 3-fold increase in plasma leucine concentration (
Tryptophan is transported into the brain by the large, neutral amino acid transport system that also transports the branched amino acids, phenylalanine and tyrosine. The ratio of the plasma concentration of tryptophan relative to the other large neutral amino acids may reflect the rate at which tryptophan can be transported into the brain. Accordingly, changes in plasma tryptophan and other large neutral amino acids (LNAA) concentrations were monitored over time in subjects for up to 240 minutes following administration of 11 g of EAAs, excluding tryptophan. As shown in
Tryptophan is the precursor of serotonin synthesis. As such, the data demonstrating decreased plasma tryptophan levels following EAA ingestion, translates into a reduction in the rate of serotonin synthesis. Because serotonin is the brain neurotransmitter that increases the perception of fatigue, reducing serotonin levels following EAA ingestion (via reduction of the precursor tryptophan) would reduce brain perception of fatigue during exercise if EAAs are taken before exercise
Thus, there has been described a composition and method of using the composition to improve athletic performance by supporting muscle protein synthesis and mental focus. stimulate growth, repair and maintenance of muscle. It is apparent to those skilled in the art, however, that many changes, clarifications, modifications, other uses, and applications for the composition and method of using are possible, and also such changes, variations, modifications, other uses, and application which do not depart from the spirit and scope of the invention are deemed to be covered by the invention, which is limited only by the claims which follow.
