MPV = mean propulsive velocity; MNR = maximum number of repetitions; RSR = relative strength ratio, defined as 1RM divided by body mass; Rep = repetitions; SEM = standard error of measurement; MPVrep Best = mean propulsive velocity attained during the best repetition; MPVrep Last = mean propulsive velocity attained during the last repetition. Data expressed as mean ± standard deviation. CI = confidence interval.
