大學棒球打者首次揮擊影響因素與效率之探討：以109學年度大專盃（公開一級）八強球隊為例

目的：首次揮擊是棒球打者在打席中主動進攻的開始，為瞭解影響其表現的因素，本研究針對大專棒球打者在不同球數、球種下，首次揮棒的結果進行檢視。方法：本研究對象為109學年度大專棒球聯賽最優級別之八強球隊48位打席達八次以上打者，由紀錄員至比賽現場就特定場次記錄其打擊表現進行分析。以重複量數二因子變異數分析，考驗不同球種與首次揮擊結果，以及球數與首次揮擊結果的效果。並將上壘率與首次打擊的安打率進行皮爾森積差相關分析。結果：球種與結果出現交互作用，除了揮空以外，直球在界外、出局以及安打的機率都高變化球。在球數平手時出現首次揮擊的機率最高。首次揮擊的安打率與上壘率有顯著的相關。結論：大專棒球打者的首次揮擊表現受到球種與球數的影響，同時也與上壘率有顯著的關係。

Purpose: The first swing is the start of an active attack of a baseball hitter in each plate appearance (PA). To understand the factors that influent the first swing, this study examined the performances and the results under different ball counts and ball types. Method: Forty-eight hitters who had more than eight PA in the best class and whose teams entering the quarter-final in 2020 University Baseball League were selected as the participants. Their hitting performance during each sampling matches were notated for analyses. The effects of ball types and ball counts on the results of the first swing were computed by using repeated measurements of Two Ways ANOVA. In addition, Pearson correlation was calculated for the on base percentage (OBP) and the rate of hit (RH) of the first swing. Results: Significant interaction was found in ANOVA of ball types and results. Simple main effect showed that the rate in all the results of the first swing for fast ball were higher than those of breaking ball except that of swing and miss. The appearance of first swing was found most in the tie of ball counts. The relationship of OBP and RH showed significant. Conclusion: The performances of baseball hitters were influence by the ball types and ball counts and related to OBP.
