swinging strength的意思|示意

The result shows that the effective swinging of left leg is insufficient and extending strength of right leg is not good at the stage of sliding.

结果表明：我国优秀女子铅球运动员在滑步阶段，左腿有效摆动不足， 右腿蹬伸力量、速度不佳。

It shows confidence. They show their strength by walking majestically and swinging their tail from left to right. It is also a sign that they are within their territory.

这是自信的表现。一边威严地走路一边左右来回摆动尾巴可以显示自己的力量，也表明它们在自己的领地上。
