月经周期心血管功能和运动能力变化规律的研究

CHANGE PATTERNS OF CARDIOVASCULAR FUNCTIONS & PHYSICAL ABILITIES IN MENSTRUAL CYCLE

本文观察了16例女大学生在整个月经周期中心血管功能及运动能力的变化规律,每3天测定1次心功能指标及运动能力指标。研究结果表明,心血管功能指标及运动能力指标在整个月经周期中均呈规律性变化,心功能指标大多在排卵日前后最高,在卵泡期最低,黄体期心功能指标比卵泡期高;运动能力指标在黄体期中期达峰值。变化规律和雌激素、孕激素分泌有关。

We have observed 16 cases of female undergraduate students on change patterns of cardiovascular func-tions and physical abilities in whole menstrual cycles and obtained nearly 4000 data of 21 parameters ofcardiac function and 3 parameters of physical ability. The research shows that all parameters of cardiova-scular functions and physical abilities change regularly during menstrual cycles. Most cardiac function para-meters are maximal around the date of ovulation, minimal in Graafian follicle stage and moderate in corpusluteum stage. Parameters of physical ability reach their peak values in the middle of corpus luteum stage.These change patterns are related to secretion of estrogen & progestin.
