本研究目的在探討花式撞球專長之高中學生在介入八週核心訓練課程後，對於受試學生擊球穩定度的影響。本研究採量化研究方式，以兩所、共計17名之高中撞球專長學生為受試對象，區分為等張訓練組與等長訓練組進行實驗，比較訓練結束後，各組前測與後測之間的差異。本訓練內容分為32個動作，等張訓練組16個動作，等長訓練組16個動作，每次訓練內容為6或7個動作，等長訓練組每個動作進行時間為30秒鐘，等張訓練組每個動作反覆15下，然後依序進行五個循環，每週訓練三次，每兩週更換一次動作，各訓練組於八週內將16個動作循環完畢。兩組受試者於訓練前，進行第一次測驗(即前測)，每位受試者測試三十球，必須使母球在撞擊目標球之後，母球及目標球均落入尾袋，兩球雙雙入袋記為一分，此一測試方法區分為身材球與非身材球，總計施測六十球。結束八週核心訓練課程後，兩組受試者均接受第二次測驗(即後測)，測試內容及方法與前測相同。各訓練組在身材球的後測進球數顯著高於前測，在無身材球的部分，前測與後測進球數之間則沒有顯著差異；另外，各訓練組在身材球的擊球穩定度也有明顯的進步。撞球運動雖不似其他競技項目必須具備強而有力的肌肉系統來支配全身獲取佳績，然透過本研究的結果證實，若能透過有計畫的核心訓練提升身體核心肌群能力，不但能使選手在打擊身材球的過程中有更好的肢體穩定性，能有效提升進球率，增進運動專項成績表現。
The purpose of the thesis was to investigate the effects of 8-week specific core conditioning on the stability of follow shot performance in senior high school billiards athletics. Seventeen senior high school billiards athletics participated in the study. They were divided from two groups, isometric training group and isotonic training group. Both of the two groups received a specific core conditioning program, the training program consisted of 32 steps (16 steps for isometric training group, 16 steps for isotonic training group). Each step was carried out 30 seconds in isometric training group and 15 times in isotonic training group. Each round executed 6 or 7 steps for five rounds, three times a week for 8 weeks. Pre and post tests were executed before and after the training program. T-test was used to compare the results of follow shoot performance before and after the 8-week specific core conditioning program. The significant level was set at α = .05. The results revealed that the results of post-test of unfixed follow shoot performance was significant better than the pre-test (P < .05) both in isometric training group and isotonic training group, however, the significant influence on fixed follow-shooting performance has not been found after the 8-week specific core conditioning program (P > .05). Eight weeks specific core conditioning program could increase the cord strength then enhances the unfixed follow shoot performance in senior high school billiards athletics.
