國中男棒球選手專項體能對跑壘速度預測情形

本研究藉由測量並收集178位國中男子棒球選手其各項專項身體能力資料進行分析，包括身體組成、垂直跳、30及60碼衝刺、T測驗、坐姿體前彎、5RM蹲立推舉、立定跳遠、5RM仰臥推撐、仰臥起坐、握力測驗等10項專項體能，以及一壘跑與二壘跑成績作為考驗其相關情形與預測能力的依據，本研究獲得之結果如下：（1）本研究之國中男子棒球選手其專項體能皆劣於國內、外學者針對成人或國家級棒球選手所獲得之數據；（2）專項體能與其一壘跑與二壘跑速度除了坐姿體前彎外，皆有顯著相關存在；（3）國中男選手之棒球專項體能預測跑壘速度變項中，60碼衝刺、T測驗，垂直跳等決定因素之預測力，達顯著水準。本研究發現男子棒球選手其專項身體能力與跑壘速度有關，建議棒球教練應長期追蹤並建立球員專項身體能力資料。

This study aimed to examine the correlations between base running speed and baseball related fitness of male baseball players from junior high schools in Kaohsiung City. The predictions of base running speed by their baseball related fitness also examined. There were total 178 male players from six junior high schools in Kaohsiung City who participated in the study. All the players were requested to take related fitness tests, consisting of fourteen events (body heights, body weights, body fats %, vertical jumps. 30-and-60 yard sprints, T tests, 5RM squats, 5RM bench presses, 5 kg weight abdominal tests, and Grip tests). The major findings of the study were summarized as follows: (1) All the baseball related fitness records of players in this study were inferior to other research results based on using the colleges or adult baseball participants; (2) There were significant correlations among their base running speed and baseball related fitness tests except sit and reach test; (3) This study results indicated that 44.2% and 76.2% of the variances in the first base running and two-base running scores individually was accounted for by 60 yard sprints, T tests and vertical jumps. The study suggests baseball coaches keeping baseball related fitness records for their player in future.
