Abstract
The development of fatigue during isometric contraction was examined in 14 athletes by on line computer analysis of the electrical activity of vastus medialis, rectus femoris and vastus lateralis. The experiments were carried out with a counterload of 50 of maximal muscle strength to complete fatigue. In the three parts of the quadriceps muscle the duration of the spike increased while the frequency decreased. No significant differences of activity were noted between the three major heads of the quadriceps muscle and the pattern of fatigue development was similar to that observed in the biceps brachii of healthy subjects.
