Abstract
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
