200-meter running problem.

27. 1 1 sec, the result is not good, but since you are a track and field team, there is still much room for improvement after systematic training for one year.

1, spikes are fine, and you must wear professional and genuine shoes. Can spike give you about 1 second?

2, rubber floor to see the specifications of the rubber floor. Some projects that cut corners may not be much better. But from what you said, what kind of land track is your current practice venue? The rubber venue will be much better than the land. First of all, the buffer is better than the land, and the friction is greater than the land, which is conducive to your play. On the rubber floor alone, I estimate that you can be faster than on land 1.3 seconds or so.

3, the startup device can improve your startup speed, which is amazing in about 0. 1.2 seconds.

You should have run on the land track for 27. 1 1 sec. Nail shoes with good site and starting device. Now you can run at once. I think you can run for about 25 seconds if you practice scientifically and systematically for a year (pay attention to diet, scientific practice methods and your efforts).

I think you can run to 23.50 seconds as soon as next year. Personal prediction. The excellent performance of middle school students is about 2 1 second. You are now 27 seconds, and it is unrealistic to improve by 6 seconds. Think the limit can reach 23 seconds.
