Why does the standing long jump regress in winter?

Physical strength drops and the center of gravity moves backward.

1, decreased physical strength. Standing long jump retrogression will be cold weather in winter, long-term lack of exercise, physical decline, after a week or two of recovery, can be restored to the original level, and then improve skills, performance will be improved.

2. The center of gravity moves backward. When landing, the foot extends too far, causing the center of gravity to move backwards, so it will regress. The solution is not to stretch your legs too far at a time, lean forward after landing, and move your center of gravity to the front of your feet, so as to ensure that the standing long jump will not regress.
