摘要
对常用走跑锻炼的强度控制和能耗计算方法进行研究。方法:201名健康青年在运动跑台进行递增负荷走跑至最大摄氧量,采集气体代谢指标建立回归方程。结果:在递增负荷下,随走跑速度的增加摄氧量急剧上升,呈现出高度的正相关。利用速度和摄氧量相关关系建立的回归方程为:男:Y=6.074X-20.921;女:Y=6.922X-19.825。对回归方程拟合优度检验显示相关性分别为0.82和0.85;标准化残差服从正态分布;回代检验显示预测值与实测值无显著性差异。结论:本研究建立的走跑速度-摄氧量方程(模型)具有可靠性和较好的精确度,可为心肺机能锻炼中走、跑运动强度的选择及运动能耗的获取提供依据,有利于提高运动健身改善心肺机能的获益率。
Background:In this study,the strength control and energy consumption calculation methods of walking exercise were studied. Methods 201 young healthy people aged 19-22 years performed the maximal graded exercise on a treadmill,oxygen uptakes were analysed during the test. Results:Oxygen uptake was increased as the walk-run speed increasing. A strong positive correlation was shown and the prediction equations were established for male:Y=6.074 X-20.921 and for female:Y=6.922 X-19.825. The goodness of fit data was 82.1% for male prediction equation and 84.7% for female prediction equation. The standardized residual had a normal distribution. Conclusions:These prediction equations are reliable and accurate. They would help young people to choose the suitable walk-run speed to improve their cardiopulmonary function through exercise. It is beneficial to improve the benefit rate of exercise fitness and improve cardiopulmonary function,and it is expected to provide reference for the establishment of targeted aerobic exercise program and the shortening of the recovery period of patients with new coronary pneumonia.
