正确的摆臂动作能够保持身体的平衡,能加大腿部的蹬摆效果。因为上下肢的摆动是协调一致的,所以要想提高步频,必须加快上肢的摆频。正确的摆臂技术在长距离跑中尤为重要。长距离跑项目中能量消耗大,谁的技术合理,谁的能量使用就越经济。而正确的摆臂动作能防止躯干沿纵轴转动,减少能量的消耗。正确的摆臂技术是:两臂在身体两侧,大小臂成90°角左右,肩关节,腕关节放松的条件下前后摆动。大小臂折叠的角度根据自身情况调整但摆臂的方向应该是前后。下面是两种错误的摆臂动作及纠正错误的方法:
The correct swing arm action can maintain the balance of the body, can increase the leg swing effect. Because the upper and lower extremity swing is coordinated, so in order to improve the pace, we must speed up the upper limb swing frequency. The right swing arm technique is especially important in long runs. Long distance running project energy consumption, who's reasonable technology, who use the more economical. The correct swing arm action to prevent the trunk along the longitudinal axis of rotation, reducing energy consumption. The right arm technology is: arms on both sides of the body, the size of the arm at about 90 ° angle, shoulder joint, wrist under the conditions of relaxation before and after swinging. The size of the arm folding angle according to their own circumstances but the direction of swing arm should be before and after. Here are two different ways to correct the swing arm movement and correct it:
