EFEITO TEMPORAL SOBRE A RESPOSTA DA PERCEPÇÃO SUBJETIVA DO ESFORÇO TEMPORAL EFFECT ON THE RESPONSE OF SUBJECTIVE PERCEIVED EXERTION EFECTO TEMPORAL SOBRE LA RESPUESTA DE LA PERCEPCIÓN SUBJETIVA DEL ESFUERZO

ABSTRACT Introduction: The session rating perceived exertion (session-RPE) is an easily applied and very useful method in the sports context, a 30 minutes period after training session having been recommended for assessment; however, there are not empiric data supporting this suggestion. Objective: To verify the relationship and the agreement between the average rating of perceived exertion (RPE) during the session with RPE values reported 5, 15 and 30 minutes after the end of the sessions. Methods: Eleven female and nine male basketball players took part at the study. The RPE was assessed by means of a CR-10 scale every 20 minutes during the session which had a duration of 1 h (average RPE session) and 5, 15 or 30 minutes after de end of the sessions. Thus, the average RPE of every session was compared with RPE values reported 5, 15 and 30 minutes after the respective session. Results: There was no difference in average RPE among the three sessions. The higher correlations were observed between average RPE session during sessions 2 and 3 with RPE reported 15 and 30 minutes after the end of the session for men (r = 0.92 – 0.91) and women (r = 0.75 – 0.82). The higher agreement values were founded between average RPE session during the sessions 1 and 2 with the RPE reported 15 and 30 minutes after the end those sessions for both genders. Conclusions: Based on these results, we suggest avoiding reporting the RPE session 5 minutes after the end of the session. Furthermore, we suggest reporting the RPE at least 15 minutes, or rather 30 minutes after the end of the session.Keywords: sports, physical exertion, heart rate.
