Abstract : Male subjects were instructed to walk as long as possible at 75% of their maximum walking speed on a motor driven treadmill. Each S walked for eight sessions. During the sessions Ss were instructed to report on a five point scale the increase in the amount of effort required by the walking task. The obtained effort scales were linear, as had been reported for shorter duration isometric muscale contractions. Correlations between the endurance scores and various physical and psychological measures suggested that while maximum walking speed was primarily related to physique, endurance was more determined by personality variables.
