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

棒球实战中击球点高度的影响运动学比较表明，在实际击球中，击球的高低击球点被认为主要是由于四肢运动的调整，而不是肩部和臀部的旋转。另外，在实际击球投射时，必须先做出“高或低”、“内或外”的决策，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。实际棒球比赛中内外击球点的影响运动学比较表明，在实际击球中，在击球时，需要先从SS阶段开始调整击球的时间协调，在时间上协调好时机，在LUP阶段开始双肩旋转，然后在IMP阶段调整左肘、双肩、右腿和肩膀的旋转和髋关节的旋转。

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.
