Values are the number of trials to reach stability. 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.
