Values are mean ± SD. Period-average differences are contrast minus control. sRPE training load was calculated as weekly training frequency × mean session-RPE × 90 minutes, reflecting the approximate duration of the primary training sessions. AU, arbitrary units; CI, confidence interval; RPE, rating of perceived exertion.
