The influence of workload ofidentical intensity and duration performed in the morning, afternoon and in the evening on the external respiration, gas-energy exchange, thermal state, cardiovascular system, nervous system and physical working capacity of sportsmen was studied. It has been established that the performance of assigned work in the microclimate with optimum conditions of heat transfer is accompanied by an increase in functional overstress and fatigue of athletes in the evening at the expense of increasing “energy cost” of such work.
