在长跑队伍中,有的人呼吸顺畅,步伐轻盈,显得很轻松。有的人一跑步就呼哧大喘,上气不接下气,有时还会出现胸闷胀痛、气憋难受、两腿无力等现象。从调查中发现,他们大多不懂得长跑的正确呼吸方法。 从运动生理学角度分析,人在跑步时,氧气需要量随着跑步速度加大而相应增加。为了适应这种情况,需要加快呼吸频率和增加呼吸深度。但是,呼吸频率的加快是有一 In the long-distance team, some people breathe smoothly, the pace of light, it is easy. Some people run a breath on the big asthma, breathless, and sometimes chest tightness and pain, gas hold uncomfortable, weak legs and so on. From the survey found that most of them do not understand the correct method of breathing long-distance running. From the perspective of exercise physiology, when people are running, oxygen demand increases with the increase of running speed. In order to adapt to this situation, it is necessary to speed up the breathing rate and increase the depth of breathing. However, there is one quicker rate of breathing
