Abstract

Electrical activity during voluntary effort was analysed in 33 normal subjects. Parameters of activity measured were number of peaks, mean amplitude, distribution of time intervals and of amplitudes between peaks. Recording from 10 sites evenly distributed over a muscle gave adequate representation of activity; force should be a fixed proportion of maximum rather than constant.
