打擊表現之生涯峰期研究-以中華職棒球員為例

本研究旨在了解中華職棒元年至二十三年所有本土打者之生涯打擊表現，以攻擊指數（OPS）為指標了解球員生涯表現趨勢，並探討全壘打、保送、打擊能力與盜壘能力，等四項數據是否依年齡不同而存在年長優勢或年輕優勢，進而了解台灣球員之生涯技能態勢。本研究以中華職棒元年開始161名本土打者之逐年表現為樣本，並以描述性統計、獨立樣本T檢定與one-way ANOVA進行分析。結果顯示：本土打者之OPS生涯高峰出現在25歲，其各項技能分別如下全壘打接近於年長球員技能，會隨著年齡增長而有提升的現象，保送雖未呈現相當明顯的趨勢，但仍偏屬年長球員技能；盜壘能力屬於年輕球員技能，會隨著年紀提升而逐年下滑，打擊能力則並未出現特別明顯的偏向。透過本研究，希望可助於了解本土球員生涯技能之態勢，並提供球團與球員洽談合約及台灣職棒日後發展之參考依據。

The purpose of this study was to explore the career peak performance of CPBL domestic players during 1990 -2012. The OPS was employed as the main indicator to explore the players’ career performance trend. In addition, HR, BB, AVG and SB were analyzed based on age in order to determine if these four performance indices were young talent or old talent skills. The data included 161 players. Using descriptive statistics, t-test and one-way ANOVA to analyze the data, the result revealed that the peak age was 25 years old. HR and BB were old player’ skills (performance improves as players get older); SB was young player’s skill (performance decreases when players get older), while AVG did not reveal any particular orientation. The results provided practical implication to contract negotiation and the overall development of CPBL.
