Abstract

A computer controlled exercise machine in which the user selects an exercise mode and its profile by programming the computer. Signals are produced by the program to control a resistive force producing device. Sensors produce data signals corresponding to the force applied to the actuating member of the system, velocity of movement and angular position which are continuously sampled at a high rate by a microprocessor operating under control of the program. The sampled data values are used to update and display performance results for the exercise and to compute the values of other parameters and, in some exercise modes, to control the amount of the resistive force.
