摘 要:目的:通过平板运动跑台和场地两种不同的测试方法,对我国成年男性走、跑过程中的气体代谢和能量消耗进行比较。方法:15名成年男性在平板运动跑台和场地完成4.8km/h、6.4 km/h、8.0 km/h三个速度的走、跑运动,使用Cortex MetaMax 3 B测定走、跑过程中的气体代谢指标变化并进行统计分析。结果:走、跑时平板运动跑台测试和场地测试之间气体指标、心率和能量消耗指标有明显差异。两种测试方法得来的数据存在线性相关。使用ICC系数和Bland-Altman法分析表明两种测试方法有非常显著的一致性和相关性。结论:相同速度下平板运动跑台走、跑和场地走、跑的能量消耗差异显著,只有直接测量场地走、跑的能量消耗才能反映日常生活中和体育健身活动中走、跑运动的真实状况。应用直线回归分析建立了平板运动跑台测试和场地测试两种方法之间的转换推导公式,根据跑台测试结果推算场地测试耗氧量和能量消耗,但由于样本量较少,该公式还需要进一步增加样本量进行验证。Objective:The purpose of this study was to compare treadmill and field test for energy cost during running and walking in adult males, to analysis the differences and establish the conversion formula. Methods: 15 adult males on the treadmill and on the field complete 4. 8 km/h, 6.4 km/h, and 8.0 km/h walking and running. The gas metabolism was determined using the Cortex MetaMax 3 B. Results. 1 ) The indicator of gas index, heart rate and energy cost were very different during running and walking. 2) There is a linear correlation between two sets of data. 3) ICC and Bland-Altman method between the two groups proved that there was a significant consistency and relevance in the data of two sets. Conclusion. 1 ) There is significant difference between the energy cost of treadmill and field test. Only the direct field measurement reflects the true state of running and walking of daily life and physical activity. 2) Established a conversion formula of oxygen consumption and energy consumption between treadmill test and field test by linear regression method, but the formula need to further for validation because of the small sample size.
