用主觀體力感覺(jué)預(yù)測(cè)武警戰(zhàn)士耐力訓(xùn)練強(qiáng)度的研究

摘要： 目的應(yīng)用主觀體力感覺(jué)量表預(yù)測(cè)武警戰(zhàn)士不同強(qiáng)度的耐力訓(xùn)練心率,為部隊(duì)耐力訓(xùn)練提供簡(jiǎn)單科學(xué)的方法。方法把主觀體力感覺(jué)(Rating of perceived exertion,RPE)和運(yùn)動(dòng)場(chǎng)上實(shí)測(cè)的運(yùn)動(dòng)負(fù)荷心率相結(jié)合。運(yùn)動(dòng)負(fù)荷的心率監(jiān)測(cè)以個(gè)人最大心率(220-年齡)(MHR)的百分比來(lái)確定,MHR從50%~90%分為9個(gè)運(yùn)動(dòng)等級(jí),記錄對(duì)應(yīng)的RPE,建立主觀體力感覺(jué)和訓(xùn)練心率的回歸方程。結(jié)果新兵訓(xùn)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(xùn)練心率的回歸方程為:老兵心率=30.11+8.02×老兵RPE(R=0.96)。結(jié)論應(yīng)用主觀體力感覺(jué)量表能夠監(jiān)測(cè)戰(zhàn)士耐力訓(xùn)練強(qiáng)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
