Abstract
An apparatus and method to evaluate the endurance of a muscle group of a user by measuring velocities of an engagement assembly coupled to a resistance element and moved by the user through a plurality of exercise strokes. A muscle group is assessed by determining a rate of fatigue for the muscle group. The method can include adjusting the controllable resistance to a resistance level, monitoring the movement of the engagement assembly against the resistance level over a plurality of repetitions, determining a relationship between the movement of the engagement assembly by the user over the plurality of repetitions, and using the relationship to determine the rate of fatigue.
Claims23
A method for assessing a rate of fatigue for a muscle group on an exercise apparatus having an engagement assembly movable against a controllable resistance by the muscle group of a user and having a monitoring system that measures a velocity of movement of the engagement assembly, the method comprising:
- adjusting the controllable resistance to a resistance level, wherein the controllable resistance is a pneumatic device;
- monitoring the velocity of movement of the engagement assembly against the resistance level over a plurality of repetitions, the velocity of movement of the engagement assembly being determined by the user while exercising;
- monitoring a pressure within the pneumatic device throughout each repetition of the plurality of repetitions;
- selectively changing the pressure within the pneumatic device to maintain the resistance level throughout a Range of Motion (ROM) for each repetition of the plurality of repetitions;
- determining a peak speed for each repetition of the plurality of repetitions and/or an average speed for each repetition of the plurality of repetitions;
- using the maintained resistance level of the pneumatic device and at least one of the peak speed or the average speed to determine a relationship between the movement of the engagement assembly by the user over the plurality of repetitions;
- and
- using the relationship to determine the rate of fatigue.
