CL = Competitive level; RL = Recreational level; T1, T2 = Trial 1, Trial 2; T2-T1 = Change in the mean between Trial 2 and Trial 1; TE_mean = Mean typical error of three consecutive pairs of the test; CV_mean = Mean coefficients of variation of three consecutive pairs of the test; ICC_mean = Mean intra-class correlation coefficients of three consecutive pairs of the test; 95% CI = 95% Confidence interval; SWC_0.2 = Smallest worthwhile change given by standard deviation × 0.2
