| Outline of Final Research Achievements |
This study was designed to examine the effect of ankle inner muscle on balance control during drop jump. Ten volunteers underwent both the drop jump - and flexor hallucis longus (FHL) muscle contraction drop jump-interventions in a randomized order. Subjects were instructed to minimize body sway during drop jump. Peak vertical and sagittal components of ground reaction force and integrated EMG activity of the FHL muscles during two 200-ms time periods either side of initial contact with the ground were analyzed and compared between interventions. The FHL muscle contraction can improve the body balance in the drop jump. The possible mechanism involves increasing muscle activity of the FHL muscle, which may be useful to derive the ankle instability patients for rehabilitation.
