Adaptive exercise machine
First Claim
1. A method of providing a resistance force to a user of an exercise machine which includes a member which is movable along a path and which is configured to engage a part of the user'"'"'s body to execute an exercise motion in which the member has a position and a velocity, comprising:
- sensing the position and the velocity of the member during the exercise motion,determining a user force exerted by the user along the path from a parameterized function of the position and the velocity,determining a velocity profile as a varying function of the position, andproviding the resistance force in a manner to cause the velocity to follow the velocity profile.

Abstract
An apparatus and method for controlling the torque of an exercise machine acting on a user is disclosed. The invention determines the torque which the user is able to exert at different positions and velocities, and develops a strength model of the user. Based on the strength model of the user, the invention determines a desired velocity profile for the user'"'"'s exercise. The velocity profile may be chosen to maximize the amount of power output by the user or to provide whatever other type of exercise specified. The invention then controls the torque acting on the user so that the exercise is accomplished according to the desired velocity profile.

11. An exercise machine, comprising:
-
a member which is movable along a path and which is configured to engage a part of a user'"'"'s body, a resistive device connected to the member to provide a resistance force to the user who executes an exercise motion in which the member has a position and a velocity, a sensor to measure the position and the velocity of the member during the exercise motion, a processor coupled to the sensor and configured to determine a user force exerted by the user along the path from a parameterized function of the position and the velocity, the processor further configured to determine a velocity profile as a varying function of the position, and a controller coupled to the resistance device and configured to adjust the resistance force to cause the velocity to follow the velocity profile. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
