Biomechanical analysis of the batting motion at different impact points in actual baseball batting.

在实际棒球击球中击球点高度的影响运动学比较表明，在实际击球中击球点高和击球点低被认为主要是由于四肢运动的调整而不是肩膀和臀部的旋转。此外，在击球被投射实球时必须先做出“高还是低”、“内还是外”的决定，然后考虑在短时间内将击球动作从LUP阶段调整到冲击阶段。内外击球点对实际击球的影响。运动学比较表明，在实际击球中，内外击球点击球时，需要进行时间协调调整，首先从SS阶段开始，时间协调从LUP阶段开始，时间协调从双肩旋转开始，然后是左肘、双肩、右腿和肩髋旋转。

Effects of the height of hitting point in actual baseball battingKinematic comparisons indicated that in hitting a ball at high and low hitting points in the actual batting is thought to be largely due to adjustment of the movement of the limbs than the rotation of the shoulders and hips. In addition, in hitting the ball was projected real must make a decision first "high or low", "inside or outside", then it is Considered that adjust the batting motion from LUP phase to impact phase in a short time.Effects of inside and outside hitting point in actual baseball battingKinematic comparisons indicated that in hitting a ball at inside and outside hitting points in the actual batting, there is a need to make adjustments temporal coordination of timing starts first at SS phase, and temporal coordination of timing, rotation of the both shoulders at LUP phase, then left elbow, both shoulders, right leg and shoulder and hip rotation at the IMP phase.
