PURPOSE: The purpose of this study was to investigate the effects of ankle muscle contraction method on strength, flexibility and balance of ankle joint in high school football player.
METHODS: Thirty-six high school soccer male players participated in this study. There were three groups (1) concentric contraction exercise (CON, n = 12), (2) eccentric contraction exercise (ECC, n = 12) and (3) CON + ECC (n = 12). Exercise program consist of plantar flexion, dorsi flexion, and inversion, eversion and these exercise was performed 10 repetition, 2set (CON+ECC=1set), 30°/sec, 60°/sec, 90°/sec, 120°/sec in each group. All subjects performed same volume of exercise condition on a isokinetic exercise.
RESULTS: First, the muscle strength of the ankle joint was significantly higher after isokinetic exercise program in plantar flexion (p<.05), dorsi flexion (p<.01), inversion (p<,05) and eversion (p<.01). Second, the flexibility of the ankle joint was significantly higher than in plantar flexion (p<.01), dorsi flexion (p<.05), inversion (p<,05) and eversion (p<.01). Third, blance of the ankle joint was higher (p<.05) in the anterior and anterolateral joints compared with the group that performed only the concentricl contraction and the eccentric contraction (P<.05) compared to before the isokinetic exercise program. In the lateral direction, there was a significant difference between groups (p<.01) and between measurement periods (p<.05). In the posterolateral direction, the combination of the concentric contraction and eccentric contractions was higher than the group with only the concentric and eccentric contraction (P <.01). In the posterior direction, there was a significant difference between the groups (p<.01) and the measurement period (p<.05). Significant differences were noted between posteromedial and medial direction (p<.01).
CONCLUSIONS: These suggest that the combined of concentric and eccentric contraction exercise of ankle joint can improve to greater balance compared with only performing concentric and eccentric contraction exercise.
