简要总结
Baseball batting is important to winning the games. Baseball batting is achieved by proximal-to-distal sequencing of body movements and controlled by the neuromuscular system. Poor lumbopelvic control could influence production and transfer of energy in the kinetic chain. This study aims to investigate the impact of lumbopelvic control in hitting mechanics and bat swing velocity in high school baseball players.
