They were randomly assigned to intervention order and interventions were 1 wk apart. A passive intervention included 40 CPIs at 5\u00b0\/s through 80% of maximum range of motion, and a fatigue intervention involved an isometric eversion at 40% of the maximal voluntary isometric contraction until the torque decreased to 50% of its initial value.<\/jats:p><\/jats:sec><jats:sec sec-type=\"main outcome measures\"><jats:title>Main Outcome Measures:<\/jats:title><jats:p>Median frequency of the peroneus longus during the fatigue protocol, energy absorption by the viscoelastic tissues during the CPI protocol, and feedforward onset and reaction time of the peroneus longus during landing.<\/jats:p><\/jats:sec><jats:sec sec-type=\"results\"><jats:title>Results:<\/jats:title><jats:p>A significant fall in median frequency (<jats:italic>P<\/jats:italic> &lt; .05) and a significant decrease in energy absorption (<jats:italic>P<\/jats:italic> &lt; .05) confirmed fatigue and a change in viscoelastic behavior, respectively.
