月经周期中P与E的波动可影响VO2max的几个决定因素,包括能源的可利用性、血液循环和呼吸。能源的可利用性取决于饮食的摄入、能源的储存和动员,这些均可影响运动时血乳酸的浓度。体重变化作为体液调节变化的可能结果,可影响VO2max,而且体液调节可影响血容量和血红蛋白浓度进而影响血液携氧的能力,血容量的变化可影响心率,而心率是心脏输出量的一个重要决定因素。同时需要肺通气提供氧,以上因素在月经周期的变化都可能影响VO2max。本文综述近年来国外对此方面问题的研究发现,当讨论VO2max的决定因素时,大部分研究显示月经周期并不影响运动时乳酸反应、体重、血红蛋白浓度及心率。虽然黄体中期VE可能增加,但VE不太可能影响VO2max。可推测认为月经周期并不影响VO2max。大部分研究发现月经周期中VO2max并无变化,也证实了这一推论。因此,就目前的研究来看,月经周期并不影响VO2max。
Fluctuations in P and E during the menstrual cycle can affect several determinants of VO2max, including energy availability, blood circulation and respiration. The availability of energy depends on dietary intake, energy storage and mobilization, all of which can affect lactate concentrations during exercise. Changes in body weight as a possible result of body fluid regulation change can affect VO2max, and body fluid regulation can affect blood volume and hemoglobin concentration and thus affect blood oxygen carrying capacity, changes in blood volume can affect heart rate, and heart rate is an important determinant of cardiac output factor. At the same time the need for pulmonary ventilation to provide oxygen, the above factors in the menstrual cycle changes may affect VO2max. This review summarizes recent studies abroad in this area and found that when discussing the determinants of VO2max, most studies show that the menstrual cycle does not affect lactate response during exercise, body weight, hemoglobin concentration and heart rate. Although mid-term VE may increase, VE is unlikely to affect VO2max. Presumably the menstrual cycle does not affect VO2max. Most studies have found no change in VO2max during the menstrual cycle, also confirmed this corollary. Therefore, the current study, the menstrual cycle does not affect the VO2max.
