MPV = mean propulsive velocity; MNR = maximum number of repetitions; RSR = relative strength ratio, defined as 1RM divided by body mass; Rep = repetitions; MPVrep Best = mean propulsive velocity attained during the best repetition; MPVrep Last = mean propulsive velocity attained during the last repetition; Lactate = blood lactate concentration. M = mean ± SD = standard deviation; CI = confidence interval; Min–Max = lowest value–highest value; CV = coefficient of variation. * = significant difference between High RSR and all other groups (p < 0.05). £ = significant difference between Medium RSR and all other groups (p < 0.05). † = significant difference between High RSR and Very Low RSR (p < 0.05). ‡ = significant difference between Medium RSR and Very Low RSR (p < 0.05).
