掷标枪是一项快速力量性的轻 器械项目。它是人体通过快速助跑后在0.2～0.3秒的时间内完成最后用力技术,作用力于标枪的纵轴,从而使标枪获得尽可能大的出手速度和适宜的出手角度,获得理想的远度。由于标枪重量 轻且呈细长体形,根据流体力学原理,空中飞行时,理想的标枪飞行状态有利于标枪更好地利用空气的上升浮力,而获得更好的空中飞行效果。因此,标枪运动员不仅需要具备很好的爆发力、跑跳能力和协调性,还应掌握合理的 Javelin throwing is a fast-moving, light-weight item. It is the body through the rapid run-up in 0.2 to 0.3 seconds to complete the final force technology, the force on the javelin vertical axis, so that the javelin get as much as possible shot speed and appropriate shot angle, to obtain the desired distance. Due to its light weight and slender body shape, according to the fluid mechanics theory, the ideal javelin flying state during airflight facilitates the javelin to make better use of the rising buoyancy of the air to obtain better flight effects. Therefore, the javelin throwers not only need to have a good explosive, jumping ability and coordination, but also should have a reasonable
