【摘要】：目的:通过对上坡快走与上坡慢跑两种不同运动形式相同速度运动过程中的摄氧量、心率、RPE、核心温度、步频等指标的实时监测,探讨人体在运动过程中相关生理指标的变化特征。方法:选取10名20~25岁的健康男性作为受试者,分别进行上坡快走和上坡慢跑(跑台速度6.4 km/h,坡度10%,运动时间40 min),采用MOXUS气体分析系统以及核心温度检测系统对受试者的相关生理指标进行实时监测。结果:(1)上坡慢跑与上坡快走相比,20 min后最大摄氧量百分比较高(P0.05);(2)上坡慢跑与上坡快走相比HR较高,且在25 min后所有时间点均有显著性差异(P0.05);(3)在20 min后的所有时间点,上坡慢跑与上坡快走相比核心温度较高(P0.05);(4)上坡慢跑10 min与35 min、40 min的最大摄氧量百分比相比较低(P0.05);上坡快走10 min最大摄氧量百分比与其他时间点相比较低,但差异不显著(P0.05)。结论:(1)上坡慢跑比上坡快走心肺反应更为强烈,能量消耗更多,这可能是上坡慢跑过程中步频较高等因素导致;(2)上坡慢跑比上坡快走运动结束时核心温度变化大,这可能与上坡慢跑时运动强度和能量消耗较高有关;(3)在上坡慢跑与上坡快走运动过程中,二者糖消耗基本相同,上坡慢跑过程中总能量消耗较高是由脂肪消耗更多导致。
[Abstract]:Objective: to monitor the oxygen uptake, heart rate, RPE, core temperature, step frequency and so on in the process of two different types of walking and jogging in the same speed, such as oxygen uptake, heart rate, core temperature of RPE, step frequency and so on. To explore the changes of physiological indexes during exercise. Methods: ten healthy men aged 20 to 25 years were selected as subjects. Up slope fast walking and uphill jogging (running speed 6.4 km/h, slope 10, exercise time 40 min), using MOXUS gas analysis system and core temperature detection system to monitor the physiological parameters of the subjects in real time. Results: (1) the percentage of maximal oxygen uptake after 20 min (P0.05); (2) was higher than that of uphill jogging (P0.05); (2), and there was significant difference at all time points after 25 min (P0.05); (3) at all time points after 20 min. The core temperature of uphill jogging was higher than that of fast walking (P0.05); (4), the percentage of maximal oxygen uptake of 10 min and 35 min,40 min of uphill jogging was lower (P0.05), the percentage of maximal oxygen uptake of 10 min was lower than that of other time points, but the difference was not significant (P0.05). Conclusion: (1) the cardiopulmonary reaction of uphill jogging is stronger and the energy consumption is more than that of uphill jogging, which may be due to the higher walking frequency during the uphill jogging process, and (2) the core temperature changes greatly at the end of the uphill jogging. This may be related to the high intensity of exercise and energy consumption during uphill jogging. (3) in the process of uphill jogging and uphill fast walking, the sugar consumption between them is basically the same, and the higher total energy consumption during uphill jogging is caused by more fat consumption.
