Dynamic strength loading per movement

Abstract

Dynamic strength loading per movement includes determining progress within a given state of an exercise. It further includes controlling, as a function of the progress within the given state of the exercise, a force generated by a motor of an exercise machine.

What is claimed is: 
     
         1 . An exercise machine, comprising:
 a motor configured to generate a force;   a cable coupled between the motor and an actuator;   a sensor configured to sense progress of an exercise within a given state of the exercise; and   a motor controller configured to control the force generated by the motor as a function of the progress of the exercise within the given state.   
     
     
         2 . The exercise machine of  claim 1 , wherein the given state of the exercise is determined based on a previously observed exercise repetition of a given user. 
     
     
         3 . The exercise machine of  claim 1 , wherein the progress within the given state of the exercise is determined based at least in part on a position of the actuator. 
     
     
         4 . The exercise machine of  claim 3 , wherein the position of the actuator is based at least in part on a measurement of a length of the cable. 
     
     
         5 . The exercise machine of  claim 1 , wherein the force generated by the motor is determined according to a resistance curve. 
     
     
         6 . The exercise machine of  claim 5 , wherein the resistance curve specifies, for the given state of the exercise, and the progress within the given state of the exercise, a corresponding amount of force to provide. 
     
     
         7 . The exercise machine of  claim 5 , wherein the resistance curve comprises at least one of an ascending resistance curve, a descending resistance curve, a mid-peak resistance curve, or a flat resistance curve. 
     
     
         8 . The exercise machine of  claim 5 , wherein the resistance curve is received at least in part by querying a movement library. 
     
     
         9 . The exercise machine of  claim 1 , wherein the given state of the exercise comprises one of a concentric phase of a repetition or an eccentric phase of the repetition. 
     
     
         10 . The exercise machine of  claim 1 , wherein the progress within the given state of the exercise is determined at least in part by determining a percentage range of motion. 
     
     
         11 . A method, comprising:
 determining, based at least in part on a set of sensor measurements, progress within a given state of an exercise; and   controlling, as a function of the progress within the given state of the exercise, a force generated by a motor of an exercise machine, wherein the exercise machine comprises a cable coupled between the motor and an actuator.   
     
     
         12 . The method of  claim 11 , wherein the given state of the exercise is determined based on a previously observed exercise repetition of a given user. 
     
     
         13 . The method of  claim 11 , wherein the progress within the given state of the exercise is determined based at least in part on a position of the actuator. 
     
     
         14 . The method of  claim 13 , wherein the position of the actuator is based at least in part on a measurement of a length of the cable. 
     
     
         15 . The method of  claim 11 , wherein the force generated by the motor is determined according to a resistance curve. 
     
     
         16 . The method of  claim 15 , wherein the resistance curve specifies, for the given state of the exercise, and the progress within the given state of the exercise, a corresponding amount of force to provide. 
     
     
         17 . The method of  claim 15 , wherein the resistance curve comprises at least one of an ascending resistance curve, a descending resistance curve, a mid-peak resistance curve, or a flat resistance curve. 
     
     
         18 . The method of  claim 15 , wherein the resistance curve is received at least in part by querying a movement library. 
     
     
         19 . The method of  claim 11 , wherein the given state of the exercise comprises one of a concentric phase of a repetition or an eccentric phase of the repetition. 
     
     
         20 . The method of  claim 11 , wherein the progress within the given state of the exercise is determined at least in part by determining a percentage range of motion.
