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.
在长达60分钟的间歇性和持续性静态收缩过程中，研究了耐力时间与平均收缩力之间的关系。对于间歇性静态收缩，发现平均收缩力的耐力极限为最大收缩力的14.0%，而对于持续性静态收缩，该极限为最大收缩力的7.9%。较弱的受试者似乎比较强的受试者具有更高的力量耐力极限。
