Why does the standing long jump regress in winter?

Physical strength decreases and the center of gravity shifts backward.

1. Decreased physical strength. Deterioration in the standing long jump is caused by cold weather in winter, long-term inactivity, and reduced physical strength. After one to two weeks of recovery, you can return to the original level. If you improve your technique, your performance will improve again.

2. Move the center of gravity backward. When landing, the feet extend too far forward, causing the center of gravity to shift backward, so you will step back. The solution is not to extend the legs too far every time you jump, and after landing, the body should lean forward and move the center of gravity to the front of the feet, that is, It can ensure that the standing long jump will not deteriorate.
