正确的跑步姿势Running Form & Style
by Stephen M. Pribut, DPM

马拉松跑的跑步姿势非常重要，因为你要一路坚持跑超过42公里，而不是4.2公里。这里总结了美国俄勒冈大学跑步教练Bill Bowerman在教学中总结的跑步姿势。实际上，在马拉松跑中，你应该站直了身子跑，不要往前倾或往后倒，也不要扭向一侧，下面一起听听Bill Bowerman是怎么说的。

Foot First: Where should you contact  脚的着地方式
有些人认为跑步时用前掌着地，也有人认为应该足跟着地。我们建议先以用中间部分接触地面。研究表明一名好的长距离跑者通常是以足中着地的。慢跑者以足中和脚跟着地，快跑者的着地点比慢跑者靠前。我们认为只有短跑选手和中短跑选手适合以前脚掌着地。可能有些人会例外，但是以足中着地对初中级跑步者是个好的方式。这样可以减少震动，缓解对小腿肌肉和足腱的压力，同时为下一个迈步做好准备。
Some say to run on the ball of your foot, others say contact the ground with the heel. We take a middle of the road approach. Studies have shown that good long distance runners usually contact with the midfoot. Slower runners contact between the midfoot and the heel, faster runners a bit further forward. We feel that only sprinters or short to middle distance runners should contact the ground with their forefoot or the ball of the foot. While there may be exceptions to the rule, this is a good way for most beginning and intermediate runners to start out. It allows for better shock absorption, less stress on the calf muscle and Achilles tendon, and better rolling forward onto the next stride. Your muscles then end up being used in a similar manner to how you walk, and this is the pattern of muscle firing and contact pattern they are accustomed to.

Hips & Head臀部和头部的姿势
这点比较难以想象：当你的脚着地时，你的臀部的位置在哪里？有些人建议，着地时你的脚应该在你的重心线的末端，也就是头臀脚三点成一线。头部保持正和直，目光看向正前方。转头的时候需要特别小心，通常是从脖子以上部分转动，避免身体的扭转，避免在行进时产生不稳定。
This part is hard to think about: Where are your hips when your foot hits the ground. Some people have suggested that your foot should be under the center of gravity of your body when it strikes the ground. A line from your head through your hips should end up at your foot. Keep the head fairly straight and look ahead. Turns to the side should be done carefully and usually mostly from the neck up to avoid twisting your body and making you unstable in your forward progression.

Arm Carriage手臂的姿势
这个姿势是在你没有使用慢跑婴儿推车，而是可以摆动双臂。首先，最重要的是不要僵直手臂，紧握拳头，完全弯曲肘部。保持放松。将手臂自然弯曲在腰线以上，不要太高或太低。两个手臂前后交替摆动，使腿部相应反方向运动。短跑选手在跑道上奔跑时手臂是完全前后摆动的，很多长距离跑步者略带弧度地摆动，但优秀的跑者不会把力气用在摆动胳膊上。换句话说，不要激烈地摆动手臂。
This is what you use when you haven't yet obtained a jogging baby stroller. Actually, it is where you allow your arms to swing. First, and most importantly, don't tense up and carry them stiffly with your hands balled up into a fist and your elbows completely bent. Rela
