- Abstract
[Purpose] To clarify whether an increase in the hip flexion angle influences balance in the windup pitching position in baseball. [Subjects] Subjects were 12 male university baseball pitchers and 12 healthy male students with no experience of baseball. [Method] We measured the shifts in the center of pressure of the subjects. The comparison of the pitchers and the healthy men was performed at the same hip flexion angle. The pitchers were compared between the hip flexion angle of the position ready to throw the ball and the maximum possible hip flexion. [Result] The pitchers showed a significantly lower shift in the center of pressure than the healthy men (p<0.05). In pitchers, the shift in the center of pressure significantly increased at the maximum possible hip flexion angle (p<0.05). [Conclusion] Baseball pitchers had superior balance in the normal wind-up position, however their balance ability decreased at the maximum possible hip flexion angle.
