—The pur- pose of this study was to determine the relationship between gluteal muscle activation and pelvis and trunk kinematics when catchers throw to second base. Forty-two baseball and softball catchers (14.74 6 4.07 years; 161.85 6 15.24 cm; 63.38 6 19.98 kg) participated in this study. Muscle activity of the bilat- eral gluteus maximus and medius as well as pelvis and trunk kinematics throughout the throwing motion were analyzed. It was discovered that at foot contact, there were 2 significant inverse relationships between stride leg gluteus maximus activity and pelvis axial rotation (r = 20.31, r2 = 0.10, p = 0.05), and between trunk axial rotation and pelvis lateral flex- ion (r = 20.34, r2 = 0.12, p = 0.03). In addition, at foot contact, a significant positive relationship between the drive leg (throwing arm side) and trunk flexion (r = 0.33, r2 = 0.11, p = 0.04) was present. The results of this study provide evi- dence of gluteal activation both concentrically and eccentri- cally, in attempt to control the pelvis and trunk during the throwing motion of catchers. The gluteal muscles play a direct role in maintaining the stability of the pelvis, and catchers should incorporate strengthening of the entire lumbopelvic- hip complex into their training regimen. Incorporating concen- tric and eccentric gluteal exercises will help to improve musculoskeletal core stability, thereby assisting in upper extremity injury prevention.
