运动被认为是生长激素(GH)和催乳素(PRL)释放的生理性调节因子,有报告指出缺氧可能影响运动诱发的GH释放。本文作者研究了缺氧和大运动量对GH与PRL水平的影响。 材料和方法 参加实验的为10名健康女性,年龄22～28岁,身高176cm,体重53～70kg,体力训练的程度各异,但这些女孩中无人进行竞赛性运动。使用电制动脚踏车测力器研究最大的心肺作功。静息的血液样品是在海平面气压和在模拟2438米、3658米及4572米高度的房间内,减压10′后采集的;在次大运动量10′后,其相应氧摄取量为56.7±0.8%(44.9～65.5%)。受试妇女完成最大运动量3′～5′,直至出现耗竭为止。血清GH
Exercise is thought to be a physiological regulator of the release of growth hormone (GH) and prolactin (PRL). It has been reported that hypoxia may affect exercise-induced GH release. The authors studied the effects of hypoxia and high exercise levels on GH and PRL levels. MATERIALS AND METHODS Participants in the experiment were 10 healthy women aged 22-28 years with a height of 176cm and a body weight of 53-70kg. The degree of physical training varied, but no one exercised in these girls. Use electric brake pedal dynamometer to study maximum cardiopulmonary work. Resting blood samples were taken at sea level pressure and in chambers simulating levels of 2438 m, 3658 m and 4572 m, depressurized by 10 ’; after 10 m of submaximal exercise, the corresponding oxygen uptake was 56.7 ± 0.8% (44.9-65.5%). Subjects completed the maximum amount of exercise 3 ’~ 5’ until depleted so far. Serum GH
