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.Keywords

The role of progesterone on PFT was well known in the normal course of the menstrual cycle. Significant increase in both progesterone (37%) and estradiol (13.5%), whereas no change in plasma FSH&LH was observed in exercising women in previous studies. Therefore this study was intended to see the limitations of the pulmonary system in adaptability to exercise in luteal phase of menstrual cycle. It was observed that exercise per se does not cause a statistically significant change in dynamic lung function parameters MMEF, PEFR, MEF 25% to 75% in either of the groups. This finding supports the hypothesis that the respiratory system is not normally the most limiting factor in the delivery of oxygen even under the predominant influence of progesterone in luteal phase which is further accentuated by exercise.Keywords
