The point of maximum perception of effort and exhaustion in exercise is believed to be based on two models of exercise tolerance- the muscle fatigue model and the psychobiological model. The muscle fatigue model proposes that high intensity aerobic exercise stops at the point commonly called exhaustion because fatigued subjects cannot continue to generate the required power output despite maximal voluntary effort. Exhaustion is a form of task disengagement rather than task failure according to the psychobiological model of exercise tolerance based on motivational intensity theory. This study aims to further the validity of the psychobiological model of exercise tolerance by studying the effect of motivational practices on the point of fatigue. The results are suggestive of improvement in exercise tolerance after motivational practices bringing out the neural correlates in point of fatigue.

Abstract


The point of maximum perception of effort and exhaustion in exercise is believed to be based on two models of exercise tolerance- the muscle fatigue model and the psychobiological model. The muscle fatigue model proposes that high intensity aerobic exercise stops at the point commonly called exhaustion because fatigued subjects cannot continue to generate the required power output despite maximal voluntary effort. Exhaustion is a form of task disengagement rather than task failure according to the psychobiological model of exercise tolerance based on motivational intensity theory. This study aims to further the validity of the psychobiological model of exercise tolerance by studying the effect of motivational practices on the point of fatigue. The results are suggestive of improvement in exercise tolerance after motivational practices bringing out the neural correlates in point of fatigue.
