MVC (N) 733 ± 119.1 823.8 ± 101.4 0.14 (90% CI = −0.2 to 0.09) 6.2 (90% CI = −12.1 to 31. 9) 0.75 (90% CI = 0.03 to 0.98) 8.6%
SP (s) 3.1 ± 0.1 3.2 ± 0.2 −0.63 (90% CI = −1.44 to 0.24) 0.16 (90% CI = −0.11 to 0.28) 0.67 (90% CI = −0.1 to 0.81) 12.2%

Trial 1 and trial 2 are respectively the baseline values of the two conditions. CV, coefficient of variation. ICC, intraclass correlation coefficient; CI, 90% confidence intervals; TE, typical error.

SJ, Squat jump; CMJ, countermovement jump; MVC, maximal voluntary contraction; SP, 20 m sprint test.
