The purpose of this study is to analyze daily variation of muscle strength of shoulder abduction in college baseball pitchers during pre-season. We continuously measured the shoulder abductor strength of pitchers in college baseball team. The mean abductor strength was 96±18 N on the first day, 101±16 N on the second day, 103±18 N on the third day, 108±16 N on the fourth day, and 113±17 N on the fifth day. A significant difference was observed between the first day and the fourth day, fifth day, and between the second day and the fifth day. The shoulder abductor strength of pitchers, therefore, varied daily during the pre-season.
