The objective of this thesis was to determine the nature of the relationship between force developed by the human leg and the electromyographic activity EMG developed in selected muscles of the lower limb. Subjects were required to pedal a bicycle ergometer ergocycle while simultaneous dynagraph recordings were made of the EMG of the thigh muscles of the right leg and the calibrated output of strain gages mounted on the right ergocycle pedal. Data from the recordings were analyzed to determine the correlation between EMG and force output, and to determine the interrelationships of all variables by means of stepwise linear regression. Results of this experiment are an initial effort to explore the possibility of developing a reliable, reproducible model with which to accurately describe the complicated inter-relationships which exist during the operation of the human leg.
