核心肌群訓練改善國中智能障礙學生身體組成及動態平衡影響保齡球運動表現之研究

本研究目的在探討國中智能障礙學生在進行12週、每周3次，每次45分鐘的核心訓練，是否可增進保齡球運動表現。方法：將12名台中市某國中特教班智能障礙類學生分為核心訓練組及一般訓練組。並在12週後，分析二組前、後測之身體組成、動態平衡及保齡球運動表現差異。結果：核心訓練組之身體質量增加.03、體脂肪率減少1.55%、肌肉量增加.50公斤、動態平衡移動距離減少74.33公分、保齡球運動表現增加54.33分，除身體質量未達顯著差異，其餘皆有顯著進步(p＜.05)；而一般訓練組組內皆未達顯著差異。兩組間比較則於體脂肪率及肌肉量有顯著差異(p＜.05)。結論：本研究之12週核心肌群訓練可顯著減少體脂肪率、增加肌肉量、促進動態平衡表現，進而提升保齡球運動表現。

The purpose of the study is to investigate whether the students with mental retardation at junior high school can promote the performance of their bowling exercise after core training executed for 12 weeks, 3 times a week, each time 45 minutes . The 12 students in a special educational class were divided into core training group (CTG) and general training group (GTG). After the 12-week course, the data of pre-post tests were analyzed to examine whether their body composition, dynamic balance and bowling exercise performance were different. The results of the study are as follows: After 12 weeks of core training, the CTG increased BMI by .03, %BF decreased by 1.55%, LBM increased by .50 kg, dynamic balance moving distance decreased by 74.33 cm, bowling scores increased by 54.33. Except for no significant differences in BMI, there were significant differences (p ＜.05) that existed in CTG, while GTG did not show significant differences. There were significant differences between the two groups in %BF and LBM change (p ＜.05). In conclusion: 12 weeks of core training can significantly reduce the %BF, increase LBM, promote dynamic balance performance, and thus enhance the performance of bowling.
