Study on the equation of endurance exercises intensity for recruits by rating of perceived exertion and heart rate

Objective:To examine the validity of rating of perceived exertion(RPE) scale to forecast exercises intensity for recruits and to formulate the equation of training intensity by RPE and heart rate' to find a simple and effective method to adjust endurance training intensity for recruits.Method:Exercises intensity was prescribed as a percentage(50% —90%) of maximal heart rate(MHR) that was dealed with 9 levels and the related RPE was recorded.The recruits were divided into control group and experimental group randomly,each group 32 soldiers.Both groups had a endurance training for 8 weeks.The experimental group was trained on RPE scale,three times a week.The control group was trained without intervention of intensity equation.Result:A linear relationship existed between %MHR and correspondent RPE.The equation of training intensity for recruits was as follows:heart rate= 37.45+7.43×RPE(R=0.952).By using the equation in training,the value of VO2max and physical work capacity(pwc)170 and the result of 3000m running in experimental group were better than that in control group after 8 weeks(P 0.05).Conclusion:The equation of training intensity with RPE and heart rate can be used in endurance training for recruits.
