Correlation between training load variables and sports performance in elite athletes during a CrossTraining competition

Abstract

Controlling training loads is important to obtain results and avoid overtraining in athletes. In CrossTraining, subjective perception of effort (PSE) has been cited as an important parameter for load control, however, little is known about the contribution of physiological parameters. The objective of this study was to investigate the correlations between training control variables and performance in elite athletes during a CrossTraining competition. Ten athletes (26.4 ± 4.5 years, 84.32 ± 6.75 kg, height 1.74 ± 0.21 m) participated in the study. The RPE values ​​were recorded at the end of each test, and the athletes were monitored in real time using a HR monitoring system (Firstbeat SPORT, Jyvaskyla, Finland). The training control variables collected were: Total training volume (VTT), PSE, training load (PSE X time), mean and maximum HR, average and training impulse (TRIMP). Pearson's correlation coefficient demonstrated the following associations with competitive performance (VTT, r=0.87; RPE, r=0.28; training load, r=0.60; HRmáx, r=0.73; HRmean, r=0.76 and TRIMP, r=0.87). In conclusion, physiological parameters showed significant correlations compared to RPE, being more suitable for monitoring CrossTraining athletes.
