Shoulder angle in sagittal view was increase sustained, but elbow angle in sagittal view was from increase to decrease in second pull phase of snatch. This result indicated that the upper arm was leaving forward the trunk, and the movement of elbow was from extention to flexion, in second pull phase of snatch.

肩关节矢状面角度在发力过程中持续增加时，肘关节矢状面角度则是先增加而后减少，这意谓著参与者的上臂在发力的过程中是有向前逐渐偏离躯干的情况产生，并且肘部的动作是先伸展而后屈曲。
