Description:
A SYSTEM, METHOD, AND DEVICE FOR DEVELOPING MUSCLE MEMORY AND A BALANCED SWING

BACKGROUND

[0001] A successful sports swing (including golf or baseball) requires a combination of strength, flexibility, balance, coordination, weight shift, rhythmic timing, repeatability, and confidence - all delivered in the short period of time it takes to make the swing. The swing utilizes the entire body to accomplish peak hitting speed and square ball impact to maximize power and direct the ball to its intended target. Repeatability of the successful sports swing requires trained muscle memory to start, execute, and finish the sports swing. The sports swing can be successfully executed when the athlete has confidence to swing without the need to think about swing mechanics, thus performing the swing with subconscious support to maximize physical skill and intuitive mental abilities in support of successful shot completion.

[0017] Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the claimed material belongs. The following terms are defined below.

[0018] “coupleable” in this context refers to being able to be mechanically joined via force(s) generated by adhesion, cohesion, friction, fastening, magnetism, tension, etc.

[0019] “fastener” in this context refers to a hardware device that mechanically joins or affixes two or more objects together, generally used to create non-permanent joints (e.g., releasable or lockable), including anchor bolts, battens, bolts (including screws), brass fasteners, buckles, buttons, cable ties, captive fasteners, clamps (or cramps, including hose clamps), clasps (including lobster clasps), clekos, clips (including circlips, hairpin clips, paper clips, and terry clips), clutches, drawing pins (thumbtack), flanges, frogs, grommets, hook- and-eye closures, hook and loop fasteners (including Velcro), latches, nails, pegs (including clothespins and tent pegs), PEM nuts, pins (including bowtie cotter pins, circle cotters, clevis fasteners, cotters, dowels, linchpins, R-clips, split pins, spring pins, and tapered pins), retaining rings (including circlips and e-rings), rivets, rock bolts, rubber bands (or bands of other materials), screw anchors, snap fasteners, staples, stitches, straps, threaded fasteners (including captive threaded fasteners, nuts, screws, washers, threaded inserts, and threaded rods), ties, toggle bolts, treasury tags, twist ties, wedge anchors, and zippers. [0020] The sports swing is a complex movement that is best accomplished by the interaction of the alternating contraction and relaxation of opposing muscle groups. Because this movement occurs in less than two seconds and must be coordinated to the millisecond, it cannot be controlled by conscious thought. It must be trained in harmony with the subconscious mind. Thus while in training, it is desirable that athletes have continuous information and feedback throughout the entire movement that they are maintaining the correct relationship between the feet, legs, hips, torso, arms, neck, and head when making the sports swing, all of which are tied to the body core trained by the device. One facet of the uniqueness of this training device and system is that it works all of the needed muscle groups from the bottom up based on specifically placed connection points and configuration of extendable and retractable components attached to the each of the arms and legs to create not just the correct swing, but also to develop muscle memory, strength, and flexibility in the swing to enhance coordination and power, as well as to provide rehabilitative training.

[0021] Embodiments disclosed herein include a device configured to utilize 360 degrees of feedback combined with core and other muscle attachment placement and release mechanisms to develop core and other muscle memory, strength, and flexibility. The device further supports weight shift and turn coordination to improve swing efficiency and unleash core and other muscle power into the sports swing. The device enhances the athlete’s ability to train muscle memory and achieve a swing that is repeatable, thus increasing confidence and ball striking performance. The device enables the player to train in partial swing and full swing modes, can be custom fitted with variable sizing and feedback levels, and can be utilized indoors and outdoors. [0022] This device focuses on improved method training of the core and other muscles used in making the sports swing, in particular, the muscles associated with the feet, legs, torso, back, shoulders, arms, and hands. As shown in FIGs. 1-5, leg training is enhanced by the unique cross placement of the extendable and retractable components that train the feet and legs to move in harmony with the hips and core. The hips are likewise connected to the arms just above the elbow with specifically varied lengths and feedback to train the hands, arms, shoulders, and back to move in harmony with the hips and core. Using this training method, the hips and core then bring the lower body and upper body into complete harmony, strength, and flexibility resulting in improved sports swing performance. By training with the methods described herein, the athlete trains for an improved sports swing based on core and other muscle fundamentals enhancing practice to improve, rather than repeating improper practice swing motions, enhancing the development of strength, flexibility, balance, coordination, weight shift, rhythmic timing, repeatability, and confidence. The device trains and strengthens the body’ s muscles to help achieve improved sports swing start position, execution, and finish, thus helping the athlete to improve the sports swing.

[0023] By using the device to practice the sports swing in a controlled and slow motion manner, the athlete is able to train strength, flexibility, coordination, weight shift, rhythmic timing, repeatability, and confidence. Once core and other muscle memory strength is developed and the athlete achieves improved flexibility and strength, swing speed can be varied with swing drills to further enhance swing improvement and further embed muscle memory. Use of the catch and release device enables the athlete to swing in a slower and more controlled manner with single arm follow through, and to achieve higher swing speeds with full swing capability. [0024] The device can include a plurality of attachment components and extendable and retractable components that work together to train the sports swing from the core and facilitate improved placement of the legs, torso, arms, neck, and head in making the proper sports swing through the specific placement of the attachment components and use of the extendable and retractable components. Placement of the attachment components can enable successful operation of the device. To assist with attachment component placement understanding, terms will be used as follows: (1) the trailing arm is the right arm for a right handed athlete and left arm for a left handed athlete; (2) the leading arm is the left arm for a right handed athlete and right arm for a left handed athlete; (3) the trailing leg is the right leg for a right handed athlete and left leg for a left handed athlete; (4) the leading leg is the left leg for a right handed athlete and right leg for a left handed athlete; (5) trailing torso means the right side of the torso for a right handed athlete, and left side of the torso for a left handed athlete; and (6) leading torso means the left side of the torso for a right handed athlete, and right side of the torso for a left handed athlete.
