ICC(2,k), intraclass correlation coefficient (absolute agreement); MCMJ_L, Modified Counter-Movement Jump Left; MCMJ_R, Modified Counter-Movement Jump Right; MDC, minimal detectable change calculated as SEMx1.96x√2. P<0.05; SEM, SE of the measure calculated as the square root of the residual mean square.
