男子跆拳道運動員慣用與非慣用攻擊腳平衡能力之差異
Differences in Balance Between Dominant and Non-Dominant Attacking Leg of Male Taekwondo Athletes
摘要
平衡能力對跆拳道運動員相當重要，由於跆拳道攻擊型態的專項特性，可能導致慣用與非慣用攻擊腳之平衡能力有所不同。因此，本研究目的在探討更適合跆拳道的臨床平衡能力測試方法，以及男子跆拳道運動員慣用與非慣用攻擊腳平衡能力之差異。招募20名男子跆拳道對打項目運動員，使用平衡感誤差計分系統（Balance Error Scoring System, BESS）、修正版星狀偏移平衡測試（modified Star Excursion Balance Test, mSEBT）及動態姿勢穩定測試（dynamic postural stability test, DPST）進行測試。實驗結果顯示：跆拳道運動員慣用與非慣用攻擊腳在BESS測試（慣用攻擊腳13.45 ± 5.75分；非慣用攻擊腳11.15 ± 4.85分）和mSEBT（慣用攻擊腳94.7 ± 7.6%腿長；非慣用攻擊腳95.5 ± 7.8%腿長）皆未達顯著差異。在向前DPST的表現，非慣用腳比起慣用腳，有較佳的內外穩定指數（慣用攻擊腳0.26 ± 0.04 a.u.；非慣用攻擊腳0.23 ± 0.04 a.u.）和動態姿勢穩定指數（慣用攻擊腳0.67 ± 0.12 a.u.；非慣用攻擊腳0.61 ± 0.09 a.u.）。本研究結論認為跆拳運動員非慣用腳有較佳向前方向之動態平衡能力，而其他靜態與動態平衡測試，較難檢測慣用與非慣用腳平衡能力之差異。未來建議嘗試其他專項動作測試，以發展更適合跆拳道運動員的臨床動態平衡測試方法。

Balance is critical for taekwondo athletes. Due to the special characteristics of taekwondo attack patterns, there could be differences in balance between the dominant and non-dominant attacking leg. Therefore, the purpose of this study is to examine the most suitable measures of balance for taekwondo athletes and to compare the differences in balance between the dominant and non-dominant attacking leg of male taekwondo athletes. Twenty male sparing taekwondo athletes were recruited to compare the measures of the Balance Error Scoring System (BESS), the modified Star Excursion Balance Test (mSEBT) and the dynamic postural stability test (DPST). The results showed that there were no significant differences on the BESS test (dominant attacking leg: 13.45 ± 5.75 points; non-dominant attacking leg: 11.15 ± 4.85 points), and mSEBT (dominant attacking leg: 94.7 ± 7.6% of leg length; non-dominant attacking leg: 95.5 ± 7.8% of leg length). The Non-dominant attacking leg had better front DPST in the medial-lateral direction (dominant attacking leg: 0.26 ± 0.04 a.u.; non-dominant attacking leg: 0.23 ± 0.04 a.u.), and dynamic postural stability index (dominant attacking leg: 0.67 ± 0.12 a.u.; non-dominant attacking leg: 0.61 ± 0.09 a.u.) than attacking leg. In conclusion, taekwondo athletes have better front dynamic balance with the non-dominant attacking leg than the dominant attacking leg, while other static and dynamic tests are less able to detect differences in balance between the athletes' legs. In the future, it is recommended to try other specialized movement tests to develop a clinical dynamic balance testing method more suitable for taekwondo athletes.
