直排輪運動訓練對學童平衡能力及下肢肌耐力之影響

Effects of in-line skating training on balance abilities and lower-extremity muscular endurance in school-age children

目的：本研究探討直排輪運動訓練對學童動靜態平衡能力及下肢肌耐力之影響。方法：以60名國小三年級學童（8.54±0.30歲）為研究對象，隨機分為訓練組及控制組各30名，訓練組接受十二週、每週二次、每次一小時（包括熱身與整理運動各10分鐘）的直排輪運動訓練，藉以瞭解直排輪運動訓練對學童平衡能力及下肢肌耐力的影響。受試者在訓練前後均進行靜態平衡能力（閉眼單足站立）、動態平衡能力（走平衡木）及下肢肌耐力（三十秒起坐）測驗。經由獨立樣本單因子共變數分析，進行比較各組在訓練前後平衡能力及下肢肌耐力的差異。結果：訓練組的靜態平衡能力、動態平衡能力及下肢肌耐力均明顯優於控制組（p＜.05）。在加入「性別」變數加以考驗後，訓練組男童的靜態平衡能力、動態平衡能力及下肢肌耐力均明顯優於控制組男童（p＜.05）；訓練組女童則在動態平衡能力及下肢肌耐力明顯優於控制組女童（p＜.05）。雖然女童的靜態平衡能力無顯著差異，但訓練組的成績仍優於控制組（24.77VS.19.49秒）。結論：國小三年級的學童，適合以直排輪運動訓練來提昇平衡能力及下肢肌耐力。此一年齡層的男童，參與直排輪運動訓練，可以提昇動態平衡能力、靜態平衡能力及下肢肌耐力；至於女童，則可以提昇動態平衡能力及下肢肌耐力。Purpose: The purpose of this study was to investigate the effect of in-line skating training on the balance ability and lower-extremity muscular endurance in school-age children. Methods: Sixty Grade 3 children (aged 8.54 ± 0.30 years) were randomly assigned to training and control group. Training group was accepted 12 weeks in-line skating training (1 hour per time including 10 minutes warming up and 10 minutes cooling down, 2 times per week), to investigate the effects of in-line skating training on the balance ability and lower-extremity muscular endurance. Subjects performed the static balance test (stand with the single foot and closing eyes), dynamic balance test (walking on the balance beam) and lower-extremity muscular endurance test (30-s chair-stand) before and after training programs. An independent one-way ANCOVA was adopted to analyze the differences of balance ability and lower-extremity muscular endurance among training and control group. Results: The results showed that training group was significant better than control group in static balance, dynamic balance, lower-extremity muscular endurance (p < .05). However, there were some differences between genders. Male training group was significant better than male control group in static balance, dynamic balance, and lower-extremity muscular endurance (p <. 05). Female training group was significant better than female control group in dynamic balance and lower-extremity muscular endurance (p < .05). The female training group showed better static balance performance than the female control group (24.77 vs. 19.49 sec), though there was no statistical significant differences between them. Conclusion: In-line skating training program was suitable to be used to improve balance and lower-extremity muscular endurance for Grade 3 children. For boys, it could improve static balance, dynamic balance and lower-extremity muscular endurance. For girls, it could improve dynamic balance and lower-extremity muscular endurance.
