The construct validity of session RPE during an intensive camp in young male Karate athletes



the aim of this study was to assess the validity of the session rating of perceived exertion (RPE) method and two objective HR-based methods for quantifying karate’s training load (TL) in young Karatekas.


eleven athletes (age 12.50±1.84 years) participated in this study. The training period/camp was performed on 5 consecutive days with two training session (s) per-day (d). Construct validity of RPE method in young Karate athletes, was studied by correlation analysis between RPE session’s training load and both Edwards and Banister’s training impulse score’ method.


significant relationship was found between inter-day (n-11 × d-5 × s-2 = 110) sessions RPE and Edwards (rvalues from 0.84 to 0.92 p < 0.001) and Banister’s (r values from 0.84 to 0.97 p < 0.001), respectively


this study showed that session-RPE can be considered a valid method for quantifying karate’s training load in young karate athletes.
