男子跆拳道選手側踢之內收肌群與外展肌群肌力相關研究

背景：跆拳道是世界最受歡迎的運動之一，而跆拳道技術有80%與踢擊的技術有關。其中側踢是用來攻擊和得分的最重要的動作之一，每一個踢擊動作皆與髖關節的伸屈動作所造成的內收肌與外展肌肌力有關。目標：本研究主要著重於跆拳道選手的臀髖節內收肌群與外展肌群之肌力與比率相關。方法：本研究參與者共15位國立台灣體育運動大學跆拳道隊男子選手（年齡19.27±0.96歲；身高176.67±5.88公分；體重68.27±10.82公斤）和17位體育系學生（年齡20.15±0.49歲；身高172.05±5.40公分；體重68.75±5.25公斤），以等速機( Biodex )45°/s和120°/s重複5次等速肌力測試。統計方法：以配對t檢定與單因子多變量分析各組之差異與組間之差異。結果：跆拳道選手之外展肌群慣用與非慣用側於PTBW (F=6.89; F=7.32, p<.05 )與TWBW(F=64.64;F=76.25, p<.001)於45°/s呈現顯著差異(p<.05)，120°/s時之PTBW(F=5.36; F=5.83, p<.05 )與TWBW(F=56.57;F=46.26, p<.001)也呈現顯著差異(p<.05)；對於內收肌慣用側與非慣用側於45°/s之PTBW(F=5.98, p<.05; F=7.29 p<.001)和TWBW(F=33.42, p<.05; F=31.93, p<.001)與120°/s之慣用側與非慣用側之PTBW (F=5.36, p<.05; F=7.29 p<.001)和TWBW (F=26.90, p<.001; F=34.84, p<.001)亦呈現顯著差異水準(p<.05)。研究結果跆拳道選手於45°/s與120°/s均優於體育系學生。結論：跆拳道選手和體育系學生於慣用與非慣用側肌力之差異可能源來自專項運動訓練；二者內收肌和外展肌的肌力比例上則是低於80%（選手：62.72%；體育系學生：67.66%）皆未達到顯著水準，即便如此，本研究所有受試者亦未有任何受傷且是健康。

Background: Taekwondo is the most popular sports in the world. There are eighty percent of taekwondo skill are related to the kicking techniques. The side kick is a one of most important actions to impact on the human body so as score. Each signal action of kick was related to the abductors and adductors strength due hip extension and flexion.

Purpose: Study were focus on taekwondo player’s hip abductors and adductors strength and ratio of abductor/adductors strength.

Methods: Fifteen National Taiwan College team of taekwondo male players (age, 19.27 ± 0.96 y; height, 176.67 ± 5.88 cm; weight, 68.27 ± 10.82 kg) and seventeen students of department of physical education (age, 20.15 ± 0.49 y; height, 172.05 ± 5.40 cm; weight, 68.75 ± 5.25 kg) participated in Biodex isokinetic dynamometer randomly tested in 45°and 120°/s for 5 repetitions.

Data analysis: pair t test and one-way ANOVA used to determine difference between two group、dominant、nondominant、abductor、adductor strength and ratio of strength.

Results: Taekwondo player’s abduction strength dominant and nondominant PTBW(F=6.89; F=7.32, p<.05 ) and TWBW(F=64.64;F=76.25,p<.001) significant difference in 45°/s and dominant and nondominant PTBW(F=5.36; F=5.83, p<.05 ) and TWBW(F=56.57;F=46.26,p<.001) significant difference in 120°/s; For Taekwondo player adduction strength dominant and non dominant PTBW(F=5.98, p<.05; F=7.29 p<.001) and dominant and nondominant TWBW(F=33.42, p<.05; F=31.93, p<.001) significant difference in 45°/s and dominant PTBW(F=5.36, p<.05; F=7.29 p<.001) and dominant and nondominant TWBW(F=26.90, p<.001; F=34.84, p<.001) significant difference in 120°/s were stronger than College student. There was no significant difference in ratio of adduction and abduction strength.

Conclusion: The marginal difference between the dominant and the nondominant side for taekwondo player and college student , may cause by taekwondo training specialization. The ratio of abduction and adduction strength in this study was lower than 80% ( Taekwondo players 62.72% and college students 67.66%) with no significant difference, even thus all participant are health and without injury still.
