Values are mean ± standard deviation for unloaded and loaded (15 kg) conditions. For effect size, values are Cohen’s D effect size ± standard error of the effect size estimate (95% confidence intervals, CI 95%). Indicates statistical significance. vGRF, vertical ground reaction force; RFD, rate of force development; RSI, reactive strength index; LESS, landing error scoring system, total score.
