Analysis of electrical activity of normal muscle in man at different degrees of voluntary effort.
  1. A Fuglsang-Frederiksen,
  2. A Månsson

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.
