现已发现在月经周期的黄体期和妊娠期孕酮水平升高。孕酮对呼吸系统的影响有通气过度、部分代偿性呼吸性碱中毒,安静时对高碳酸血症通气反应(HCVR)增强及对缺氧通气反应(HVR)增强。有人提出,通气反应增强可以对整个运动能力有不利影响。如果在月经周期出现这种情况,那么黄体期的运动能力应该下降。然而有关黄体期和卵泡期运动能力有无影响的报道颇不一致。1对象与方法1.1实验对象2011年4~7月期间,针对鞍山师范学院附
It has now been found that progesterone levels are elevated during the luteal phase and gestational period of the menstrual cycle. Effects of progesterone on the respiratory system hyperventilation, partial compensatory respiratory alkalosis, hypnotic hypercapnia ventilatory response (HCVR) enhancement and hypoxic ventilatory response (HVR) increased when quiet. It has been suggested that an increased ventilatory response may have an adverse effect on the overall motor ability. If this happens during the menstrual cycle, then the exercise capacity of the luteal phase should decline. However, the reports about whether or not luteal phase and follicular phase motor ability are quite different are quite inconsistent. 1 Subjects and Methods 1.1 Subjects During April to July 2011, for the Anshan Teachers College attached
