Endurance limit of force in long-term intermittent static contractions

Abstract

The relationship between endurance time and the mean force of contraction was investigated in intermittent and sustained static contractions over a long period of time (60 min). For intermittent static contractions the endurance limit of the mean force of contraction was found to be 14.0%, and for sustained static contractions it was 7.9% of the maximal force of contraction. Weak subjects appear to have a higher endurance limit of force than strong subjects.
