摘要

对10名受试者进行4次连续30分钟的相同强度(50%最大摄氧量)运动,间隔30分钟休息时间,检测体温、摄氧量(VO2)、心率(HR)、出汗率和血浆渗透压的变化。尽管有休息间隔和体液流失的补充,但VO2仍在逐渐增加。连续运动时的HR、直肠(Tre)和平均体温(Tb)。热调节效率呈上升趋势,每次运动开始时出汗反应的延迟时间缩短。结论是,在长期连续工作中,代谢和温度对运动的反应也会发生漂移,在进行长时间间歇运动的脱水受试者中也会发生漂移。它不是由运动期间的体温调节受损引起的,而是由休息期间代谢过程的恢复不足引起的。

Thermoregulatory and metabolic responses to repeated bouts of prolonged cycle-ergometer exercise in man.

Changes in body temperature, oxygen uptake (VO2), heart rate (HR), sweating rate and plasma osmolarity were examined in 10 human subjects, performing four successive 30 min exercise-bouts of the same intensity (50% VO2 max) separated by 30 min rest periods. In spite of the rest intervals and replacement of body fluid loss there was a progressive increase in VO2. HR, rectal (Tre) and mean body (Tb) temperatures in consecutive exercise bouts. The thermoregulatory efficiency showed an increasing tendency, and a delay in the sweating response at the beginning of each exercise was shortened. It is concluded that a drift in metabolic and temperature responses to exercise, reported throughout a long-term continuous work, occurs also in the euhydrated subjects performing a prolonged intermittent exercise. It is not caused by an impaired thermoregulation during exercise but rather by insufficient restitution of metabolic processes during rest intervals.
