The isometric endurance of the palmar flexors was measured in 11 subjects who had the blood supply to the forearm occluded by means of a pressure cuff on the upper arm. The endurance load was determined as a percentage of the maximum strength of each muscle group and, in this study, varied from 35 to 85%. Load was graphed against endurance and equations were established for the relation which, under the conditions of high loading in the experiment, appeared to be linear.
contraction metabolism; strength as a predictor of endurance; contraction producing intramuscular vascular occlusion
