体育院系女生与女大学生月经不同时相植物神经机能探析

Autonomic Nerve Function at Different Phases of Menstruation between Girl Students of Physical Education And Other Specialities

对 51名体育院系女生 (实验组 )和 51名非运动员女大学生 (对照组 )在月经周期的行经时相、卵泡时相和黄体时相进行直立试验和卧倒试验 ,比较其植物神经机能的变化。实验结果表明 ,各组在月经周期不同时相的心率和植物神经指数的变化没有显著差异 (P >0 0 5) ;在月经周期的同一时相实验组的心率和植物神经指数的变化幅度比对照组小 ,具有显著性差异 (P <0 0 1) ,这可能是对运动应激适应的结果 ,它有助于植物神经对内脏机能的有效调控 ,满足肌肉活动和提高运动能力的需要。

By the experiments of erect and prone position on the menstruating phase,oogenic phase and luteinic phase during the menstrual cycle between 51 girlstudents of physical education (expermental group) and 51 girl students of other specialities(contrast group),changes of their autonomic nerve functions are compared.The nesults show that there is no notable difference between the every groups at the changesof heart rate and autonomic nerve index(p>0 05) at different phases during the menstrul cycle; the changing ranges of heart rate and autonomic nerve index of experimental group are less than those of contrast group and there exists marked difference (p<0 01) at the same phase during the menstrual cycle. This may be the result that the girl students of physical education are suited to the adaptation of exercise stress, and it is halpful to perform the regulation of autonomic nerves toward viscera function and meet the neet the needs of muscle movements and improving exercise abilities.
