The elasticity of the green plastic runway determines the difference between the plastic runway and the concrete runway.

Most of the post-80s generation have grown up playing on the cement track, and have fallen down and up on the cement track numerous times. With the development of society, more and more environment-friendly plastic runways have replaced the original concrete runways into primary schools, middle schools, universities and even kindergartens. So what's the difference?

Because the cement track is very hard, it is often used in this training to have a great effect on the body. The plastic runway is different, the biggest difference is that the plastic runway is elastic and the concrete runway is not elastic.

The plastic runway USES a lot of rubber particles during the construction process, so the elasticity is also the most physically exhausting, and the reaction force of the training is larger than that of other runways. You run a circle on the plastic runway will feel the body will involuntarily up to play, so it's bigger than you give energy, so you will be faster, but in the meantime, you also need to pay more attention to guarantee the balance of the body. Before we run laps on the concrete runway will obviously feel the pain of the body, but you on the plastic runway ran a few laps, every step forward is affected by the reaction of the runway,

So it's very relaxing.

The raw material determines the difference between the two runways, and elasticity is the most intuitive way to show the difference in the practice between the green plastic runway and the cement track.
