Absolute and body mass normalized data was shown as mean ± standard deviation (mean ± SD). Differences between elite and sub-elite athletes were calculated using body mass normalized data for the first assessment. d = effect size, AUC = area under the receiver operating characteristics curve, W = mechanical work, Fpeak = maximal force, P = power, PA = pulling arm, LA = lifting arm, n = Body mass normalized data.
