Female sex hormones, estrogen and progesterone regulate various phases of the menstrual cycle. Hormonal changes tend to affect various parameters of physical fitness. Maximum oxygen uptake (VO max) is a measure of aerobic power. This study was planned to assess effect of different phases of menstrual cycle on cardiorespiratory parameters like pulse rate, respiratory rate and VO max.
100 female medical students in the age group of 17-22 years were studied for three consecutive menstrual cycles. Weight, resting pulse rate, respiratory rate and VO max were measured during premenstrual phase (20-25 day) and postmenstrual phase (5 to 10 day).
It was observed that there was a significant increase in body weight, pulse rate, and respiratory rate during premenstrual phase. There was a decrease in VO max during the premenstrual phase.
This study indicates that there is decreased cardio-respiratory efficiency during premenstrual phase.
女性性激素，雌激素和孕激素调节月经周期的各个阶段。激素变化往往会影响身体素质的各种参数。最大摄氧量（VO max）是有氧能力的一种衡量指标。本研究旨在评估月经周期不同阶段对心率、呼吸频率和VO max等心肺参数的影响。
对100名年龄在17 - 22岁的女医学生进行连续三个月经周期的研究。在经前期（第20 - 25天）和月经后期（第5至10天）测量体重、静息心率、呼吸频率和VO max。
观察到经前期体重、心率和呼吸频率显著增加。经前期VO max下降。
本研究表明经前期心肺效率降低。
