铅球最后用力的理论基础及专项力量训练特征

Theory Base that the Shot is Finally Putted Forth One's Strength Reaches only the Item of Force Drills Explores the Unpack

对大量文献资料进行数理统计和综合分析,提出了划分铅球最后用阶段的新观点:推铅球最后用力阶段,是从滑步过程中支撑腿水平向上运动结束之时开始到铅球离手的过程·整个最后用力阶段分为单支撑用力和双支撑用力出手两个阶段,单支撑最用力阶段对减小铅球预先速度的损耗、加快左脚着地和拉长工作肌有重要意义·

Analyze by means of carrying on mathematical statistics and synthesis to a great quantity of literature datum＇s, Propose to divide the shot finally in the way of phase the fresh concept： Pushes the shot finally puts forth one＇s strength phase, Is through slips props up in the pace process leg level the unwiring movement finishes hour starts paring from the hand process up the shot. Entirely finally puts forth one＇s strength phase is divided into that the list props up to put forth one＇s strength with twin supports putting forth one＇s strength to get off one＇s hands two phases, The list props up to put forth one＇s strength most phase adjust decreases the shot velocity wear and tear beforehand, Speeding up left wing foot, there is the significant sense in the earth with lengthening work flesh.
