Examples of Newton's second law of motion and gymnastics?

Newton's 2nd law has to do an enormous amount with gymnastics. The force needed to do certain things has to do a lot with your movements. Tumbling in gymnastics uses a lot of force. But the height of your tumbling has to do with the amount of force you use.

Example: If I'm doing a round-off back handspring back-tuck and i want it to be really high. Then i am going to need to put alot of force into the ground after my back-handspring so that i can get the height that i want.
