Why the study?
Session RPE is based on the Borg Category-Ratio (0-10) scale, but there is no evidence on how substituting the Borg 6-20 RPE scale influences session RPE.
Does the BORG-RPE scale provide substitutable estimates of perceived exercise training intensity compared to the BORG-CR10 scale in recreational athletes?
Does the BORG-RPE scale provide substitutable estimates of perceived exercise training intensity compared to the BORG-CR10 scale in recreational athletes?
The BORG-CR10 and BORG-RPE scales provide substitutable estimates of perceived exercise training intensity for Session RPE.
May allow clinicians flexibility in BORG scale selection for sRPE; leaves open validation in elite or clinical cohorts.
PURPOSE: The Session RPE (sRPE) is an accepted method of monitoring training in athletes in many different sports. It is based on the Category-Ratio (0-10) RPE scale (BORG-CR10) developed by Borg. There is no evidence how substitution of the Borg 6-20 RPE scale (BORG-RPE) might influence the sRPE. METHODS: Systematically training, recreational level athletes from different sport disciplines performed six, randomly ordered, 30-minute interval training sessions, at intensities based on peak power output (PPO), designed to be easy (50%PPO), moderate (75%PPO) or hard (85%PPO). sRPE was obtained 30-min post-exercise using the BORG-CR10 or BORG-RPE and compared for matched conditions. RESULTS: The average percent of heart rate reserve (%HRR) was well-correlated with sRPE from both BORG-CR10 (r = 0.76) and BORG-RPE (r =0.69). The sRPE from BORG-CR10 and BORG-RPE were very strongly correlated (r = .90) at matched times. CONCLUSIONS: Although producing different absolute numbers, sRPE derived from either BORG-CR10 or BORG-RPE provide substitutable estimates of perceived exercise training intensity.
