摘要:	棒球揮棒速度與擊球初速是打擊者重要關鍵。地雷管更是一項功能性爆發力訓練器材，但利用地雷管介入棒球選手訓練之相關文獻仍不足。目的：本研究目的旨在探討6週地雷管螺旋爆發力訓練對棒球運動員揮棒速度、旋轉加速度、揮棒時間、擊球初速、揮棒功率與手腕峰值速度之效益程度。方法：招募24名大學棒球選手 (年齡：20.25 ± 1.52歲、身高：176.87 ± 6.40公分、體重：74.25 ± 8.00公斤) 為研究對象；依擊球初速度隨機均分為地雷管螺旋爆發力訓練組 (rotational landmine training, RLT) 與控制組 (control group, CG)，隨後進行6週訓練介入。所得數據以二因子混合設計變異數分析檢定兩組揮棒速度、旋轉加速度、揮棒時間、擊球初速、揮棒功率與手腕峰值速度在前、中、後之變化情形且以皮爾森相關積差分析後測數據。顯著差異水準訂為α = .05。結果：RLT在揮棒速度與手腕峰值速度顯著優於CG (p < .05)。再者，RLT在揮棒速度、旋轉加速度、揮棒時間、擊球初速、揮棒功率與手腕峰值速度皆顯著提升 (p < .05)。結論：6週地雷管螺旋爆發力訓練可改善棒球運動員揮棒速度、旋轉加速度、揮棒時間、擊球初速、揮棒功率與手腕峰值速度。 Bat speed and Exit velocity are critical factors for baseball hitters. The landmine is a functional power training equipment; however, and it still lacks the relevant literature concerning how to adopt the landmine to train baseball players power. Purpose: This study investigated the effects of 6-week landmine explosive training on improving baseball players' bat speed, rotational acceleration, time to contact, exit velocity, swing power, and peak hand speed. Method: 24 collegiate baseball players recruited to participate in the research (Age: 20.25 ± 1.52 years, Height: 176.87 ± 6.40 cm, Weight: 74.25 ± 8.00 kg) were randomly and evenly divided into the rotational landmine training (RLT) and control group (CG) based on the exit speed. A 6-week rotational power training intervention was conducted; meanwhile, the mid- and post-tests were conducted in the 4th and 7th weeks. Two-way ANOVA, mixed design analyze the pre, mid, and post variables variation in bat speed , rotational acceleration, time to contact, exit velocity, swing power and peak hand speed between two groups. Pearson's correlation product difference compared the correlation among all the variables. The level of significant difference was set at α = .05. Results: RLT presented a significantly higher bat swing speed and peak hand speed compared to the CG (p < .05). Furthermore, the RLT showed significant improvements in bat swing speed, rotational acceleration, swing time, exit ball velocity, swing power, and peak wrist speed (p < .05). Conclusion: A 6-week rotational landmine power training may enhance the bat speed, rotational acceleration, time to contact, exit velocity, swing power and peak hand speed for baseball athletes.
