Notes: n-trials is the number of trials needed to reach the indicated ICC value; -- indicates that the ICC value was never achieved; p is the probability (rounded to three decimal places) that the ICC value is significantly different from zero; F1 and F2 are the first and second peak ground reaction force variables, respectively; F1LR and F2LR are the loading rates (average slope of the line) preceding these peaks; and IMP is the impulse for the first 100 ms of the landing; SD is the standard deviation.
