[The specific characteristics of thermoregulation in athletes in different specialties]

Skin temperature in 10 sites, the temperature of the body "nucleus", sweating during physical loads in training were recorded in sportsmen of different specialization in different ambient temperatures. The body temperature was studied in conditions of cooling (26 degrees C) in water for 10 min. The temperature of extremities skin (hand, foot) dropped mode dramatically in sportsmen-swimmers during cooling in water as compared with skiers, gymnasts and the control groups. During physical work of 250 Watt, the temperature in external auditory meatus and of skin was more increased in swimmers than in other subjects. The greatest differences were found in temperature of hand, foot and forehead skin. When tested by the PWC170 technique, the thermoregulatory tension was less in sportsmen than in control group. The efficiency coefficient of muscular work seems to be higher in sportsmen than in the subjects with one-year training.
