Abstract: A resistance training apparatus and method for providing a plurality of training vectors having points of origin variable by direction and elevation to a trainee. The apparatus may accommodate a plurality of trainees and provide multiple training vectors to each trainee. The apparatus provides the training vectors by attaching tethers such as elastic cords to harnesses worn around body portions of an athlete in a configuration that allows the athlete to perform a sports-specific or therapeutic movement at an optimum speed. In one embodiment the apparatus includes a base forming the training area and a pair of tower assemblies, each providing elastic cords for attachment to the harnesses worn by the athlete. In another embodiment the apparatus provides at least sixteen training vectors to a trainee. In yet another embodiment the apparatus provides training vectors to patients or trainees who cannot fully support their own body weight.

Abstract: An exercise garment and system of obtaining access to audio while exercising, the garment carrying an electrical cable removably connected to an earphone and an audio source carried by the person exercising. Methods are also disclosed.

Abstract: A resistance swing training apparatus and method for providing resistance opposing the rotation of the hips of athletes performing sports-specific movements such as the golf or baseball swing. The apparatus provides the resistance by attaching tethers such elastic cords to a harness worn around the waist of the athlete in a configuration that allows the athlete to perform the sports-specific movement at optimum speed. In one embodiment the apparatus includes a base forming the training area and a pair of training modules for providing the elastic cords for attachment to the hips of the athlete. The lateral spacing and elevation of the elastic cords may be adjusted to fit the athlete. The resistance may also be adjusted in a wide range of resistances to fit the athlete.

Abstract: A physical training apparatus and method for providing forces opposing the motion of a trainee through the range of motion of the trainee while performing various movements. The apparatus includes means for providing resistance forces to multiple body parts of the trainee for training multiple muscle groups of the trainee simultaneously. The apparatus may provide forces of relatively constant magnitude or varying magnitude to various parts of the body through a predetermined range of motion of the body performing sports specific or therapeutic body movements. In one aspect, the resistive forces are provided training modules that are easily attached and detached from the apparatus. The apparatus may also provide resistive forces originating from various lateral and vertical positions relative to the trainee.

Abstract: A vertical jump exercise apparatus may be used to train and condition participants in sports demanding a high degree of vertical jumping ability. Elastic codes fastened to the waist of the user provide a nearly constant resistive force, thereby simulating increased body weight to strengthen leg muscles and to improve motor reflexes. Generation of the nearly constant force is accomplished by directing one or more of the elastic cords beneath or away from the exercise area, thus allowing use of an increased length of cord. Directional control for the jumper, cord following to prevent fouling of the cord, and reduced friction are provided by movable tracking assemblies that may pivot or move linearly and may be provided with pulleys. The tracking assemblies may also serve as force imbalance indicators for the elastic cords.
