经体育科研人员研究,在短跑等田径项目中,顺风和逆风的不同气象条件,运动员的成绩差别非常明显。通常顺风风速每秒2米时,百米成绩能比无风时快0.15秒,正因为如此,田径比赛规则上明文规定:距离200米和200米以下的径赛以及跳远、三级跳远、投掷等项目,凡顺风时平均风速超过每秒2米者,所创纪录不予承 Research by sports researchers, in the track and field events such as dash, downwind and headwind of different meteorological conditions, the difference between the performance of athletes is very obvious. Usually wind speed of 2 meters per second, the result of 100 meters faster than the wind when the 0.15 seconds faster, because of this, the rules of the track and field game expressly provides: distance of 200 meters and 200 meters below the track and long jump, triple jump, throwing Project, where the average wind speed down more than 2 meters per second, the record will not be accepted
