体育系大学生力量素质与心脑血流动力学指标相关性的研究

The Correlation between Muscle Strength and Cardio-Cerebral Homodynamic Index of College Students Majoring in Physical Education

目的:通过评定运动后若干心脑血流动力学指标,探讨体育系大学生力量素质与心脑血流动力学指标的相关性。方法:测试12名健康男运动员进行5分钟台阶实验后的体成分、力量素质和心脑血管血流动力学参数,分析各指标间的相关性。结果:运动训练和瘦体重含量可影响大脑中动脉各参数,但不具有显著性(P>0.05),瘦体重、哈佛台阶评定指数与平均峰流速具有显著正相关性(P<0.05)。结论:运动训练和瘦体重含量可以影响运动后大脑中动脉血流动力学参数,增加身体肌肉含量和降低体脂含量,有助于改善健康运动人群大脑中动脉的调节能力。

Purpose： This study aimed to measure the effects of exercise on cardio-cerebral homodynamic to investigate the relationship between muscle strength and cardio-cerebral homodynamic index of PE college students.Methods： 12 healthy athletes were tested.After 5 minutes of Haverford Steps Experiment,the MCA parameters,cardio-cerebral homodynamic and body composition index recorded electronically.Results： Effects of physical training and lean body mass affect parameters of MCA without significant（P0.05）.There is significantly positive correlation between lean body mass and Haverford Steps index with Vm（P0.05）.Conclusion： Physical training and lean body mass affect homodynamic index of MCA immediately after exercise.Increasing lean body mass and decrease body fat content might improve MCA responses in healthy athletes.
