用主觀體力感覺預測武警戰(zhàn)士耐力訓練強度的研究

摘要： 目的應用主觀體力感覺量表預測武警戰(zhàn)士不同強度的耐力訓練心率,為部隊耐力訓練提供簡單科學的方法。方法把主觀體力感覺(Rating of perceived exertion,RPE)和運動場上實測的運動負荷心率相結合。運動負荷的心率監(jiān)測以個人最大心率(220-年齡)(MHR)的百分比來確定,MHR從50%~90%分為9個運動等級,記錄對應的RPE,建立主觀體力感覺和訓練心率的回歸方程。結果新兵訓練心率的回歸方程為:新兵心率=37.45+7.43×新兵RPE(R=0.952);老兵訓練心率的回歸方程為:老兵心率=30.11+8.02×老兵RPE(R=0.96)。結論應用主觀體力感覺量表能夠監(jiān)測戰(zhàn)士耐力訓練強度。
Objective To examine the validity of using rating of perceived exertion(RPE) scale to prescribe exercise intensity of soldiers,thereby finding a simple and effective method to adjust intensity of endurance training.Methods Maximal heart rate(MAR) was determined using difference between 220 and age.Exercise intensity was prescribed as a percentage of maximal heart rate(50%～90%),and the related rating of perceived exertion(RPE) was recorded,which uses a subjective rating from 7 to 20 to quantify an individual's perceived exercise intensity.Results A linear relationship between %MHR and RPE exists for groups of recruits and veferans.For recruits,heart rate=37.45+7.43×RPE(R=0.952).For veterans,heart rate =30.11+8.02× RPE(R=0.96).Conclusion The RPE scale is a valid method to monitor exercise intensity of soldier
