Abstract: An exercise and performance evaluation apparatus including a revolving belt or other engagement surface on which a subject can perform forward, backward, or sideways bipedal locomotion or other exercise movement, a means for securing the position of the subject relative to the frame of the apparatus, a means for measuring the force applied by the subject to the engagement surface, and a means for monitoring and/or controlling the velocity of the engagement surface. Securing the subject relative to the frame of the apparatus facilitates monitoring velocity as a function of time. Processing of velocity and force as a function of time allows for recording and analysis of data such as the maximal exertion force-velocity curve. Force-velocity-duration data for exertions is analyzed in terms of an intensity function. The apparatus allows exertions to be performed throughout, and outside, the first quadrant of a force-velocity-duration space.

Abstract: A bipedal locomotion exercise and performance evaluation apparatus including a revolving belt, a harness for securing the position of a subject on the belt, a harness-force measuring means, and a belt volocity monitoring and controlling means. The harness may be secured on various points of a subject and includes push/pull engagement means. An overhead harness may be used to reduce effective body mass. The velocity of the belt may be controlled by a unidirectional or bidirectional motor/brake system. Velocity of the belt may also be controlled by a brake only. A digital processor may be used to control the motor and/or brake as a function of the forces applied allowing multiple operating modes. Recording of velocity and force as functions of time facilitates analysis of exercise performance. The apparatus allows exertions throughout the first quadrant of a force-velocity-duration space, and outside that first quadrant.
