Application of a Modified Rating of Perceived Exertion Scale and Weight Loss on the Control of Football Training Load

The current study aims to introduce a modified Rating of Perceived Exertion Scale to collect both the pre-training rating of perceived exertion(Pre-RPE)and post-training rating of perceived exertion(Post-RPE),in order to obtain the accumulated training rating of perceived exertion(Acc-RPE)of football players.Meanwhile,weight loss and dehydration ratio(%)of players during training were also collected to control the training load.The hypothesis was“dehydration ratio and Acc-RPE were better ways to control the training load of football players than weight loss and Post-RPE”.18 professional football players(23±3yrs,177.2±6.2cm,72.9±7.2kg,23.2±1.7BMI Index)were chosen as subjects to test the hypothesis experimentally.The results showed that there was no significant correlation between weight loss and Post-RPE(P>0.05),but a moderate correlation between weight loss and Acc-RPE(P<0.05,R=0.49);while there was a low correlation between dehydration ratio and PostRPE(P<0.05,R=0.39)and a moderate correlation between dehydration ratio and AccRPE(P<0.01,R=0.52).Resultsverified the hypothesis.
