[Possibility and effectiveness of increasing the work capacity of humans by warming the body].
Parameters of work capacity (general, physical, mental, special) of exercising cadet-pilots were measured. It was found that during exercise-induced hyperthermia their work capacity initially increased and then decreased. When rectal temperature reached 38.74 +/- 0.01 degrees, the best results, i.e. those that were 28.1% better than the baseline, were seen in physical tests (work on the apparatus) and in seven mental tests. This level of hyperthermia attained by muscle work in a thermoneutral environment brought about adequate mobilization of cardiac rhythm regulation and spyrographic parameters whose price was not superior to physiological limits. It appears that the development of exercise hyperthermia is not due to the drive of the thermoregulation system to return to thermal homeostasis, as it is suggested by the current concepts of homeostasis, but, conversely, its drive to reach a higher level of thermoregulation (1.5 degrees higher) which is characterized by the best results of work as well as by adequate mobilization of the leading functional systems of the human body.
