Abstract: A system for use in exercise having a flexible member which passes over a pulley. Sensors produce output which is used by a processor to compute the velocity of the pulley and distance travelled by the flexible member. A force sensor and a level sensor connected to the pulley produce outputs which are used to compute the tension applied to the flexible member. Data related to the use of the system computed using the outputs is displayed for the user. The system can produce performance information related to the use of the device. The system can be self-contained in a housing or output can be delivered to a remote device for computing, storage and display.

Abstract: A sled for use in exercise which is pushed by a portion of a user's torso. The device has an extension member extending outwardly from a frame. A pusher member for receiving a portion of the user's torso is mounted to the end of the extension member, the frame has a lift device for reversing the direction of travel. A disc brake provides variable resistance to movement. A strain gauge sensor is used to provide performance information.

Abstract: An exercise apparatus and method for applying one or more lateral resistive loads to drive, swing and other phases to participants while performing complex motions at low or high speeds to condition one's body to better and more quickly perform physical movements at high speeds. Elastic members may be used to generate resistance emanating from a ground-based or vertically-positioned apparatus. The elastic members may connect to one or more body parts simultaneously. The apparatus may be mechanically designed to fully retract the elastic members into the apparatus to maintain resistance while participants are in close proximity to the apparatus. The apparatus provides a plurality of self-contained elastic members and provides participants the ability to alter the vertical and horizontal positions of each elastic member's emanation point from the apparatus. This provides ability to control applied resistance vectors between the attachment point on the participant and the apparatus.

Abstract: A system and method for over speed and resistive training is provided. The method may comprise applying an assistive training force to a trainee which assists the self locomotion of the trainee to reach an over speed condition. The method may further comprise applying a resistive training force to the trainee which resists the self locomotion to the training along the training path, the resistive training force being applied to the trainee while the trainer is in an over speed condition. The forces, either resistive or assistive, may vary linearly. The system may comprise a pair of modules, each module comprising a frame carrying a plurality of pulleys and a resistance cord. Each of the modules is adapted to provide a training vector to a trainee and is positioned on opposite side of training path to provide both resistive and assistive training vectors.

Abstract: Embodiments allow the application of a settable and/or a programmable resistance to a trainee's leg Drive Phase and/or Recovery Phase while walking or running over extended or infinite distances. Multiple mechanical or electrical feedback loops or combinations of both to monitor the applied resistance to the Trainee by the tether or tethers and then control the amount of breaking (drag) or propulsion created by the Mobile training module during the acceleration and constant speed training phases to accurately generate, control and transfer resistance through the elastic tethers to the Trainee. Embodiments apply multiple, non-varying loads or programmable loads to multiple body parts of a trainee where applied resistance can be manipulated to both increase or decrease over distance as desired by trainee while the trainee is walking, running or sprinting over any distance.
