Background:The validity and reliability of the Borg 6–20 rating of perceived exertion(RPE)scale has not been tested among Chinese people from China' Mainland.The purpose of this study was to test:1)The validity of Leung Chinese version and Wang Chinese version of the Borg 6–20 RPE scale;2)The reliability of Wang Chinese version RPE scale;and 3)The agreement of these two Chinese versions of the RPE scale among young healthy adults from China' Mainland.Methods:A total of 26 subjects(11 males,15 females;age 22.7±3.0 yrs)volunteered to participate.They performed one(n=3),two(n=14),or three trials(n=9)of the Bruce treadmill protocol test within 9.0±5.1 days(validation trials),and 30.4±27.9 days(reliability trials).Power output,heart rate,oxygen consumption,and RPE were recorded.Results:RPE was significantly correlated with power output(Leung version rs≥0.75,Wang version rs≥0.73),heart rate(HR)(Leung version rs≥0.84,Wang version rs≥0.87),and oxygen consumption(VO2)(Leung version rs≥0.80,Wang version rs≥0.81)(all p<0.01).The overall test-retest interclass correlation was 0.94(p<0.01).No significant differences in correlations(RPE against power output,HR and VO_(2))between trials existed for the reliability tests of Wang version scale.No significant differences in correlations(RPE against power output,HR and VO_(2))between the two Chinese versions of RPE scale existed.Conclusion:Both Chinese RPE scales are valid among young healthy Chinese mandarin speaking adults.The Wang scale is reliable,and the Leung and Wang scales show superior agreement with each other.
