用力投掷

Technology relatively complicated many throw projects javelin throw, its intact technologies through holding a javelin the run-up win most heavy speed, Join and throw step and get momentums, act on the end of the breaking out type the axis of ordinates of the javelin hard, Make javelin at suitable angle, throw and produce at shoulder javelin.

掷标枪技术是比较复杂的多轴旋转的投掷项目，其完整技术是通过持枪助跑获得最大的速度，连接投掷步获得动量，通过爆发式的最后用力作用在标枪的纵轴上，使标枪能沿着适宜的角度，将标枪经肩上掷出。

Objective Analyzing program was designed to get some important parameters in Javelin throw ing process.

方法通过理论分析把人体简化为一个由15个刚体组成的多刚体系统；使用高速摄影机拍摄了运动员在最后用力阶段标枪投掷的实际过程。

In the javelin throw, the left leg plays the roles of guiding, braking and sustaining in the join of cross steps and final force.

投掷标枪中，左腿在交叉步与最后用力的衔接中起到了引导、动和支撑的作用。

According to the throwing order, the technique of Javelin throw can be divided into 4 parts: holding javelin, run-up with javelin, delivery and maintaining balance.

一般按投掷的顺序，将标枪的技术分为握枪、持枪助跑、最后用力和标枪出手后维持身体的平衡4个部分。

Throwing range of the arm is small and movement of the arm"s turning over is relatively early; in the stage of the right leg"s supporting, the time of the right leg amortizing is longer, the range that the right knee amortizing is relatively large, assignment of the amortizing time and

建议：在交叉步结束右脚着地至标枪出手阶段，尽量缩短右腿单支撑的时间，进一步提高右腿的支撑能力，提高投掷臂的技术水平；在训练和比赛中要进一步提高身体各环节加速的能力和保持速度的能力；应加强对最后用力及其他概念的理解，这样对进一步认识和研究掷标枪运动有辅助作用。

The velocity origins the slide stage, then it passed the transition stage to transform the velocity last spurt the release. So the transitional skill is very important during the whole throwing.

铅球的出手速度来源于运动员滑步阶段获得的速度，经过过渡阶段的转化成为最后用力的初速度，因此过渡技术的好坏在整个投掷过程中起着举足轻重的作用。

In the instant of touchdown of the left foot, the angle between shoulder and hip was 58°, the angle of pull was 136°, the angle of axis between shoulder was 19°, the speed of left shoulder was 3.49 m/s, the speed of right shoulder was

①腾空阶段，拉引角变化幅度大，投掷臂并没有随身体向投掷方向转动，而是向后主动用力，这可能是发生肩锁关节扭伤脱位的重要因素。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
