摘要
目的:探討在相同轉動慣量下,分別改變球棒的質心或重量,對揮棒表現與肌電活化之影響。方法:12位大專甲組男子棒球員為本研究受試者,分別使用4支改變重量、但質心位置相同的一般木棒,以及1支可改變質心位置的客製化球棒進行4種不同轉動慣量(極小、小、中、大)的揮棒。每種測試情況須以最大努力揮棒3次。以影像分析系統分析揮棒表現,並以肌電圖分析揮棒期前導手的肱二頭肌、肱三頭肌、屈腕肌、伸腕肌的肌肉活化。結果:在相同轉動慣量下,改變球棒的質心或改變重量,對揮棒表現沒有顯著差異(p>.05)。當轉動慣量越小,擊球速度越快(p<.05),且2種不同類型的球棒有相同的現象。結論:無論改變球棒的質心或重量,只要轉動慣量相同,會有相同的揮擊表現。

Purpose: To explore the effect of baseball bats, under identical moment of inertia (MOI) with various center of mass (COM) and weight on swing performance and muscle activation. Methods: Twelve college Level I baseball male players were recruited as subjects, who performed swing tests under four levels of MOI (very small, small, middle, large) with four different weights of wooden baseball bats and one adjustable COM of customized baseball bat. Each test processed three trials with the subject’s maximal effort. An image analysis system was used to analyze the swing performance, and the muscle activation of four muscle on leading hand was analyzed by electromyography. Results: No significant swing performances were found between the baseball bats of changing COM and weight under identical MOI (p>.05). The faster swing velocity was found along with the smaller MOI (p<.05), and two different types of baseball bat had the same phenomenon. Conclusion: Whether to change the center of mass or weight of baseball bat have the same swing performance, as long as the same moment of inertia.
