| 摘 要： | 以中国优秀女子公路自行车运动员为研究对象,研究长期比赛对她们心率变异性的影响,探讨心率变异性（HRV）早期诊断心脏疲劳的实效性,同时对1,6-二磷酸果糖（FDP）的营养干预效果做动态观察。连续30天的多日赛后总体心率变异性没有产生明显改变,比赛＋果糖组比赛后心率变异性和比赛组相比,也没有明显区别。说明在本赛季连续30天的多日赛对心脏的交感和副交感神经支配都未产生明显影响。磷酸果糖对心脏的营养干预作用不明显。

| Abstract: | Taking some Chinese elite female road cyclists as the subjects, this study focuses on the effects of multi-day race on their heart rate variability (HRV) and explores the effectiveness of early diagnosis of HRV for heart fatigue. Dynamic observation of FDP nutrition intervention was made. After the race for 30 days, there was no significant changes of HRV in general. And compared with the competition group, HRV of the competition+fructose group showed no distinct difference. This indicates that a 30-day race does not exert significant effects on sympathetic and parasympathetic regulation of heart. FDP has no evident function of nutrition intervention on heart. |
