The assessment of internal training load (ITL) using the session rate of per- ceived exertion (Session-RPE) has been already experienced in youth Taekwondo (Haddad et al., 2014). Nevertheless, no studies investigated the reliability of this method in pre-adolescent performing pre-competitive (PC; learning aim) and com- petitive (C; successful aim) training. Thus, this study aimed to evaluate the reliabil- ity of the Session-RPE (CR-10 scale; Foster et al., 1996) to monitor the ITL of youth taekwondo athletes during PC and C training sessions. Five female (age:12.0± 0.7y; height:1.54±0.08m; body mass:48.8±7.3kg) and four male (age:12.0±0.8yrs; stature:1.55±0.07m; body mass:47.3±5.3kg) pre-adolescent taekwondo athletes were monitored during 17 training sessions (100 individuals training sessions) within 35-days. The summated heart rate zone method (Edwards et al., 1993) was used as a reference measure of ITL; the CR-10 scale was administrated immediately (1stmin) and 30 minutes (30thmin) after training session. The values of Edwards’ and Session- RPE method were regressed (P≤0.05). Higher values emerged for PC (1stmin: r=0.67, R2=0.45, P
