| 内容記述 | The purpose of this study was to investigate the muscle activation levels of the hip muscles during pitching motion as ball speed was increased. Six college baseball pitchers were participated in this study. Surface electromyography data were recorded in pivot leg from 6 muscles : adductor longus (AL), gracilis (GR), adductor magnus (AM), rectus femoris (RF) , biceps femoris (BF) and gluteus medius (GM). The pitching motion was divided into 5 distinct phases: wind-up, early cocking, late cocking, acceleration, follow-through. The results demonstrated that high level muscle activity (greater than 40% maximal voluntary contraction) was found in GM during early cocking phase, and in AL, GR, AM and BF during late cocking phase, and in AL, GR and BF during acceleration phase. Then, the activity level of the hip muscles in the slow ball pitching and fast ball pitching was compared. Significantly higher muscle activity was showed in fast ball pitching in AL, GM, and BF during early cocking phase, in BF and AL during late cocking phase, and in AL, GM, and RF during acceleration phase. The findings from this study indicate that high muscle activity have been shown in the abductor of the hip joint during early cocking phase that produce translational movement, and high muscle activity have been shown in the adductor and extensor of the hip joint during late cocking phase and acceleration phase that produce rotational movement. |
