田径运动场地从只有一个直跑道到马蹄形、篮曲式、三圆心式等,发展到今天的半圆式。场地的设计越来越完善,越来越有利于提高运动技术水平和成绩。目前国内外公认的半圆式400米场地具有其他场地无可比拟的优点,可谓是“标准”式的。随着新技术革命的兴起和多学科的渗透、交叉,对场地的研究会越来越深入。我们通过对田径场弯道的使用和计算,发现弯道的计算和设计还有欠缺之处,特别在计时已达到百分之一秒的今天,如能争取到这百
Track and field venues only from a straight runway to the horseshoe, basket music, three heart-shaped, etc., developed to today’s semi-circular style. The design of the venue is more and more perfect, more and more conducive to improving the level of athletic skills and achievements. Currently recognized semi-circular 400 meters venues have unparalleled advantages of other venues, can be described as “standard” type. With the rise of the new technological revolution and multidisciplinary infiltration and cross-cutting, the research on venues will be more and more in-depth. Through the use and calculation of the corners of the track and field, we find that there are still some shortcomings in the calculation and design of the corners. Especially when the timing has reached one hundredth of a second today,
