  • F1,h, horizontal peak force during landing; F1,v, vertical peak landing force; Dj, jumping distance.

    Values are means ± s.e.m. The t-test analysis assumed unequal variances.

    Type I, profiles in which the arms intercept the major force peak; type II profiles in which the timing of body contact with the force plate is prior to the timing of the peak forces.
