    Abstract:
    Rodríguez-Marroyo, JA, Blanco, P, Foster, C, Villa, JG, and Carballo-Leyenda, B. Expanding knowledge about the effect of measurement time on session rating of perceived exertion. J Strength Cond Res 37(1): 230-233, 2023-The purpose of this study was to analyze the effect of postexercise rating times (from 0 minutes to 4 weeks) on session rating of perceived exertion (sRPE). Twenty-five athletes (12 women and 13 men) from different sports (sprinting, endurance running, cycling, and volleyball) were involved in this study. At least 3 training sessions per subject were quantified based on sRPE using a visual analog scale. The scale was administered immediately after, at 5, 10, 20, and 30 minutes, 24, 48, and 72 hours, and 1, 2, 3, and 4 weeks postexercise. In addition, the effect of rating time on sRPE was studied according to the training intensity. For this, the training sessions were classified (based on the 30-minute rating) as easy (sRPE < 3), moderate (sRPE 3-5), and hard (sRPE > 5). A significant (p < 0.001) main effect of the postexercise rating time on sRPE was found. There were significant (p < 0.05) differences between sRPE obtained at 30 minutes and those obtained immediately after hard training sessions and at 1, 2, 3, and 4 weeks postexercise. There was no significant effect of rating time on sRPE in the easy and moderate training sessions. In conclusion, the present data suggest that athletes' sRPE may be obtained in a valid and reliable manner within a time frame of 5 minutes to 72 hours posttraining. The effect of postexercise rating time on sRPE seems to be conditioned by the training intensity, especially in those training sessions whose training intensity was high (sRPE > 5).
