Default 打羽毛球时不要猛仰头

春天来了,打羽毛球的人又多了起来,http://bbs.cneclub.com/。可对于那些不经常运动,尤其是长期伏案工作的人而言,打羽毛球时最好不要猛仰头。
  打羽毛球时,仰头是跳起和后撤接球时的常用动作。在做这个动作时,http://jtaq.sdedu.net/,“由于颈部弯曲、颈伸角度加大,无疑会使颈部负荷加重,稍有不慎就可能对颈部和背部造成一定伤害。”因此 ,在近距离打球时,球过头顶,http://www.dwkjy.com/,不要猛仰头、后弓背部去追接球,以免造成损伤。
  其实不光是羽毛球,打网球、壁球等其他球类活动时也需要注意。而要尽量避免这类运动损伤,就不能忽略热 身活动。
  热身时需要兼顾颈肩部和背部肌肉。预热颈肩部肌肉可做头绕环动作,做这个动作速度不要太快,使支持颈椎 的各部分肌肉得到适度拉伸。
  拉伸背肌动作也很简单,先抬起手臂,以肩部为圆心弯曲的手臂为半径向下划弧,吐气,然后停滞一下,再划 弧上举吸气,热身过程中胳膊尽量外展,保持胳膊在身后运动,http://www.heroone.cn/。这样可以有效放松并拉伸背部肌肉。
