The track of the sports ground is very exquisite, a stadium with an oval track of usually 400 meters. According to the IAAF Facilities Manual, the standard semi-circular stadium runway is 400 meters long and consists of two straight lines and two bends.
At present, the main technical dimensions of the standard sports track recommended by IAAF are: radius: 36.5 meters.
The calculated radius of lane separation is 36.80 meters.
The calculated line length for one lane and one bend is 1 15.6 1 m, and the calculated line length for two bends is 231.2m..
One straight line is 84.39 meters, two straight lines are 168.78 meters, and one lane and one circle is 400 meters.
Knowledge expansion
Plastic track is a common sports field material, which is widely used in track and field running. Compared with the traditional cement or asphalt track, the plastic track has many unique advantages. The following are the main advantages of plastic track:
Shock absorption performance: the plastic track has good shock absorption performance, which can reduce the impact and pressure of athletes during sports. The softness of plastic materials can absorb the impact force, reduce the risk of joint and muscle injuries, and make athletes more comfortable in training and competition.
Elastic effect: the plastic track is elastic, which can provide appropriate rebound force and enhance athletes' jumping ability and explosive force. Athletes running on the plastic track can give full play to their speed and strength and improve their performance and competitive level.
Anti-skid: The surface of plastic runway has good anti-skid performance, and it can maintain good friction even in wet or rainy weather. This is very important for the safety of athletes and can effectively reduce the risk of falling and slipping.
Durability: The plastic track has high durability and can withstand long-term use and frequent training. The special structure and manufacturing technology of plastic materials enable the runway to resist daily wear, climate change and ultraviolet radiation and maintain a long service life.
Convenient maintenance: Compared with traditional cement or asphalt runways, the maintenance cost of plastic runways is lower. The runway surface is smooth and flat, and it is not easy to accumulate water and scale, and it is easy to handle when cleaning. In addition, some putty scraping and repairing work can be easily carried out to repair the damage caused by wear or use.
Environmental protection: Plastic racetracks are usually made of environmentally friendly and non-toxic materials, and will not produce harmful volatiles and pollutants. At the same time, the plastic runway can be recycled and has little impact on the environment.
Generally speaking, the plastic track has good shock absorption performance, elastic effect, anti-skid, durability and convenient maintenance, which can provide a good sports environment and ensure the safety and health of athletes. Therefore, the application of plastic track in track and field sports is more and more extensive, and it has become an ideal sports venue material.
