Conventionally, there were many studies about the efficacy of muscular assessment for throwing shoulder injury. On the other hand, there was no report regarding utility of the self-assessment for throwing performance. In this study, we reported whether the evaluations of muscular strength of the shoulder joint contribute to the throwing performance. 126 pitchers affiliated with the Gunma Prefecture High School Baseball Federation in 2007 had medical checkup and evaluated the examination items. Each player was also surveyed on his pitching performance by questionnaire at the examination. All players were male, the average baseball career was 98.5 (10 ∼ 240) months and 68 pitchers (50.8%) had current and past shoulder pain. The average maximum pitching speed was 125.1 (100 ∼ 140) km/h. By logistic regression analysis, the significant item about classification of the performance of the pitcher was throwing side external rotation strength at 0 position. The evaluation of external rotation strength at 0 position may be important when a baseball pitcher cared for the environment of his shoulder joint.
