Descriptive (mean ± SD), reliability (ICC, CV%) for all variables for the countermovement jump test. Avg = average of all trials in a session; Hv: highest value in a session; SD = standard deviation, S1 = session 1, S2 = session 2, S3 = session 3, ICC = intraclass correlation coefficient, 95% CI = 95% confidence intervals, CV% = coefficient of variation.
