This study was performed to examine declines in strength and proprioception after a single bout of overhand baseball throwing. Twenty-three university students volunteered for this study and were placed into three groups. Subjects completed a pretest consisting of joint position sense testing (ARPP), isotonic strength testing (1 RM IR and ER), and isokinetic strength testing (concentric IR and ER at 120°/s). Following this, excluding control, subjects completed an overhand throwing session consisting of 75 throws at 75% of perceived maximum effort at a distance of 60 feet 6 inches. This was followed by a posttest that was identical to the pretest. The results revealed a significant difference in the ARPP pre and post-test values for the recreationally active group and the baseball players, but no such difference for the control group. Both isotonic and isokinetic test showed no significant difference from pre to post-test
