a: indicates significantly different to jump-height asymmetry in the CMJ (p = 0.025); b: indicates significantly different to jump-height asymmetry in the DJ (p = 0.014); CV = coefficient of variation; ICC = intraclass correlation coefficient; CI = confidence intervals; UCMJ = unilateral countermovement jump; L = left; R = right; cm = centimetres; UDJ = unilateral drop jump; GCT = ground contact time; s = seconds; RSI = reactive strength index; CODS = change-of-direction speed; m = meters.
