摘要

本研究的目的在探討重量訓練對女性月經週期過程血壓與自主神經系統的影響。招募月經週期正常女性21名（21.9 ± 1.2歲），隨機分配為坐式生活及重量訓練（重訓）二組。受試者從月經開始，每7天進行2個月的心律變異度及血壓檢測。第2個月開始，重訓組每週進行2次的訓練，訓練有8種不同阻力運動，每種運動以70%最大肌力進行3組12次反覆，共4週。研究結果顯示，重訓使副交感神經活性在月經開始的第1週明顯下降。女性在月經週期的後半階段收縮壓有較低傾向。同時重訓受試者的收縮與舒張血壓起伏變化較非運動組平穩。本研究結論為：女性的血壓、心率變異度受月經週期荷爾蒙的變化影響，透過重訓可以使心血管變異穩定，在月經開始的前後進行重訓需要更多的恢復時間。本研究的主要發現顯示重量訓練對女性血壓控制的好處。

The purpose of this study was to examine the influence of weight training on blood pressure and autonomic nervous balance in women during the normal menstrual cycles. Twenty-one normally menstruating women were recruited for this study. Participants were assigned into weight training group and sedentary group in a random order. Heart rate variability and blood pressure were monitored at rest for every 7 days after menstrual bleeding for 2 complete menstrual cycles. Participants were performed eight different types of resistance weight trainings twice a week for 4 weeks (12 repetitions per set, 3 sets, 70% maximum strength). The results showed that parasympathetic nervous activity was significantly decreased in the first week after menstrual bleeding. Systolic blood pressure tended to be lower during the luteal period for the both groups. Changes in diastolic and systolic blood pressures were less pronounced for the weight training group as compared to the control group. This study concludes that the blood pressure and heart rate variability were influenced by the menstrual cycle hormones, whereas the weight training could improve the stabilization of blood pressure. It took a longer recovery time for weight training before and after the menstrual bleeding. The result of the study suggests a hemodynamic benefit of weight training for young women in regulating the blood pressure.
