20世纪80年代,苏联运动员及教练员到中国参赛,谈到撑竿跳高的起跳方向应该“向上”,于是,长期以来在我国撑竿跳高界,很多人都信奉这种观点。然而有关研究表明,我国撑竿跳高运动员在起跳时的身体重心腾起角却明显大于国外优秀运动员(见表),这一事实使人们不禁质疑:既然强调“向上”跳,为什么苏联的世界级撑竿跳高运动员的起跳腾起角度反倒比我们小得多?
In the 1980s, Soviet athletes and coaches entered the Chinese competition. When it comes to the direction of pole jump, the direction of the take-off should be “upward”. Therefore, many people believe in this view that the pole vault has long been in our country. However, the relevant research shows that the fact that the pole-rising angle of Chinese pole-vaulting athletes at the time of take-off is significantly larger than that of outstanding foreign athletes (see table) makes people wonder: since the emphasis on “upward” jumping and why the world class Pole vault athletes take off from the angle but much smaller than us?
