1. Field of the Disclosure
The present disclosure relates generally to exercise and, more particularly, to fitness and training equipment.
2. Description of Related Art
Given a host of health problems that can arise from a relatively-sedentary lifestyle and improper exercising techniques, there is a renewed interest in personal fitness and preventative healthcare. Consequently, there is now an abundance of fitness equipment, such as treadmills, stair-climbers, stationary bicycles, etc. Even with so many pieces of fitness equipment on the market, there are ongoing efforts to provide better equipment.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Fitness equipment, such as treadmills, stair-climbers, stationary bicycles, etc. are ubiquitously present. Fitness equipment also comes in simpler varieties, such as exercise mats, exercise balls, jump ropes, and suspension training equipment. Irrespective of the type of equipment, the focus is usually on targeting discrete muscle groups. By way of example, conventional suspension training equipment (e.g., gymnastic rings, TRX training equipment, etc.) permits training of different muscle groups through different types of exercises. However, since the only acting force on a suspension trainer is gravity, the counteracting motion is usually a two-dimensional force applied counter to the gravitational force. Consequently, this results in movement that is largely confined to a single plane of motion. Thus, for those that use suspension training equipment, it is virtually impossible to realize tri-planar resistance (or resistance through all three planes of motion, namely, sagittal, transverse, and frontal). In other words, suspension training equipment usually provides resistance for only a single plane of motion. Thus, conventional suspension training equipment usually requires multiple different exercises in order to effectively the various muscle groups.
The disclosed fitness equipment (hereafter abbreviated as “Space Trainer”) overcomes the shortcomings of conventional suspension training equipment by incorporating resistance training. Thus, the Space Trainer allows a user to target different muscle groups using tri-planar coordination of movement, which was previously difficult (if not impossible) to achieve using conventional suspension training equipment. The resistance is provided by mechanically coupling an elastic resistance band between suspension training straps. Also, by making modular the pieces of the Space Trainer, greater versatility is provided to the user.
Having provided a general overview of the Space Trainer, reference is now made in detail to the description of the embodiments as illustrated in the drawings. While several embodiments are described in connection with these drawings, there is no intent to limit the disclosure to the embodiment or embodiments disclosed herein. On the contrary, the intent is to cover all alternatives, modifications, and equivalents.
The left strap comprises a left upper segment 106a, 106b, 106e, a left middle segment 112a, and a left lower segment 124a. The left strap comprises an adjuster 108a that is located on the left upper segment 106a, 106b, 106e, which permits adjustment of the length of the left strap. The embodiment of
Similar to the left strap, the right strap comprises a right upper segment 106c, 106d, 106f, a right middle segment 112b, and a right lower segment 124b. The right strap comprises an adjuster 108b, which permits adjustment of the length of the right strap. The right strap also comprises a fastener 104a. The right upper segment 106f is mechanically coupled to the right middle segment 112b by an insertion connector 122b. The right middle segment 112b is, in turn, mechanically coupled to the right lower segment 124b by another insertion connector 110b. The Space Trainer 100 further comprises a right handle 120b, which is mechanically coupled to the right lower segment 124b by one or more insertion connectors 126b. Again, it should be appreciated by those having skill in the art that, in a preferred embodiment, the connectors 122a, 110a, 126a may be removable, thereby making the right strap modular.
For the embodiment of
The elastic bands 114, 116, 118 provide varying levels of resistance between the right strap and the left strap. Thus, unlike conventional suspension training equipment, the Space Trainer 100 permits tri-planar resistance, thereby allowing a user to target more muscle groups than possible through a single plane of motion.
To the extent that the left strap and the right strap function as the suspension component, while the elastic bands 114, 116, 118 function to provide resistance between the straps, the straps are preferably inelastic. Thus, in a preferred embodiment, the middle segments 112a-112b (collectively 112) and lower segments 124a-124b (collectively 124) are approximately one (1) to two (2) inches wide, approximately ten (10) to twenty (20) inches in length, and comprise industrial grade nylon webbing with heavy-gauge nylon stitching that allow for the insertion of the connectors 122, 110, 126. The upper segments 106a-106f also comprise industrial grade nylon. However, unlike the middle segments 112 and the lower segments 124, the upper segment 106 is approximately six (6) to approximately eight (8) feet in length, thereby allowing the upper segments 106 to have somewhere between approximately three (3) to four (4) feet of variability when adjusted.
The handles 126 are preferably constructed using a polyvinylchloride (PVC) tube for the grip, which is threaded with ¾-inch nylon webbing. As such, the handles 126 can serve as either grips (for hands) or stirrups (for feet).
Also, to the extent that the Space Trainer provides suspension training, the left fastener 104a and the right fastener 104b are used to suspend the straps from an anchor, one embodiment of which is shown with reference to
With this in mind, attention is turned to
The upper segments of the straps 106 are secured to the anchor 206 through their respective insertion connectors 302. The upper segments 106 are in turn mechanically attached to their respective middle segments 112 through square insertion connectors 304a, 304b (collectively 304). Again, it should be appreciated that, while square insertion connectors 304 are shown, connectors of any shape can be used to achieve substantially the same function. The middle segments 112 are, in turn, mechanically secured to the lower segments 124 by another set of square insertion connectors 306a, 306b (collectively 306). At the end of the lower segments 124, handles 120 are attached. Similar to
It is worthwhile to note that, while three segments (upper, middle, lower) are shown with reference to
From the embodiments of
Conventional suspension training equipment (e.g., gymnastic rings, TRX suspension training, etc.) does not have variable resistance bands 114, 116, 118. As such, conventional suspension training equipment largely provides for training in a single plane of movement.
Unlike conventional suspension training equipment, the Space Trainer combines body-weight suspension training and stability with continuous, variable band resistance in opposing vectors of motion that alternate and engage differently through concentric and eccentric phases of any given exercise in regards to, for example, internal and external rotational components of ancillary movement through long bones during dynamic movement (similar to the movement that one experiences in real life activities). This design allows for movements and exercises to pass through all three planes of motion (transverse, sagittal, frontal), simultaneously or independently, through a single exercise, which would otherwise call for multiple arrangements and sequences of two dimensional exercises to equal the same amount of muscle activation, muscle firing, metabolic equivalents, motor coordination and degree of functionality.
The blend of resistance and suspension training, along with tri-planar coordination of movement, creates a dynamic rotational stabilization effect that is allows for both eccentric and concentric phases of motion, which translates directly to measurable biomechanics and motor control. Benefits and uses of the Space Trainer include: (a) an increase in the number of individual muscles activated and fired to perform movement, which reduces and balances the total tension applied over the joint and increases metabolic rates; (b) minimal to zero impact sustained by joints and soft tissue during exercises; (c) proper neuromuscular control of stabilizing muscles and primary movers during movement patterns to reduce individual muscle strain as a result of dysfunctional or absent muscle stabilizers firing; (d) versatility in transportation and exercise options for home or travel use; (e) adjustable band resistance for different exercise levels and exercise program progressions; (f) adjustable suspension trainer portion with bilateral or unilateral use of handles for increased exercise options; and (g) full body workout adaptability, simultaneously between the axial skeleton with upper and lower extremities inclusion.
The Space Trainer also allows for varying degrees of resistance by combining different elastic bands 114, 116, 118 with varying degrees of elasticity. Since these bands 114, 116, 118 can be removed and used independently of suspension component (e.g., anchor (
Previously, linear method of this training or rehabilitation would normally require up to a dozen or more different exercises to isolate and train the inhibited muscles of the posterior chain in order to reduce pressure placed on the anterior aspect of the soft tissue of the shoulder joint. Those linear, isolated approaches were time-consuming and instruction-intensive because the exercises were performed sequentially and independently of each other. Consequently, this increased the room for error, thereby increasing the possibility for further injury or dysfunctions. The reason being that it is difficult to combine absolute functional motion with movements occurring independently in single movement planes void of rotational transitions and coordinated muscle firing patterns.
By contrast, the Space Trainer permits training of the scapular stabilizers of the shoulder through standing biceps curls and/or standing back rows to reduce impingement of the bicipital-labral complex and restores adequate sub-acromial space. For example, standing bicep curls begins with the patient facing the Space Trainer with supination of the palms while holding the handles 120, extending the elbows with the shoulders flexed to ninety degrees. As the biceps curl is initiated, the adductive forces of the band 118 provide a resistance prior to bicep flexion. This resistance affects scapular retraction and depression (or anatomical positioning of the shoulder blades) concomitantly with humeral external rotation through posterior shoulder cuff activation, followed by a concentric phase of the bicep curl which naturally includes further external rotation of the humerus, elbow flexion and wrist supination. As an eccentric phase is initiated, internal humeral rotation is counteracted and controlled, with concentric contraction of scapular stabilizers during muscle lengthening phases of the bicep, which usually requires more stability and control than the concentric phase.
The next exercise example, standing back rows, begins with the patient facing the Space Trainer with a neutral grip or palms facing, while holding the handles 120, extending the elbows and flexing the shoulders to a natural support (relative to foot placement under the anchor 210) and maintaining hip extension. As the back row is initiated, adductor forces of the band 118 provide a bicep flexion and humeral external rotational resistance while extending the humerus, flexing the elbow and supinating the wrists through the concentric phase. The initial bicep flexion and humeral external rotation resistance affects the stabilizing sequence of the scapula with respect to thoracic spine extension, at end range. Once the eccentric phase of the standing back row begins, motor firing of internal rotators of the humerus, serratus anterior and pectoralis major and minor engage to promote and assist in scapular retraction and depression, which relieves aberrant pressures at the anterior glenorhumeral joint that can cause pain and/or movement dysfunctions.
The Space Trainer promotes an increase in eccentric phase control though the use of more muscles (as compared to greater exertion), which is important since a majority of muscle strains are experienced during eccentric loading.
Any process descriptions or blocks in flow charts should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included within the scope of the preferred embodiment of the present disclosure in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure.
Although exemplary embodiments have been shown and described, it will be clear to those of ordinary skill in the art that a number of changes, modifications, or alterations to the disclosure as described may be made. For example, while heavy-gauge nylon webbing is described as the preferred material, it should be appreciated that other suitable materials may be used to manufacture the Space Trainer. Also, while the straps are described to be inelastic, it should be appreciated that, for some training exercises, the straps may indeed be elastic (to a certain degree), thereby permitting even more variability for the user. Moreover, while specific shapes and dimensions are provided for the components of the Space Trainer, it should be appreciated that these shapes and dimensions are only for illustrative purposes. For example, while a triangular karabiner (or other releasable clip) is described, it should be appreciated that other types of removable clips (such as those found on key rings) can be used without detrimentally affecting the form and function of the Space Trainer. Furthermore, while the preferred embodiments of
