How to kick in self-swimming

There are five formulas for freestyle kicking: driving the thigh, bending the knees and pressing down, moving the knees up, taking turns with both feet, and staggering the kicks

Explanation of the specific movements of the freestyle kicking:

1. When kicking, keep your legs slightly straight, relax your knees, and flatten your feet into an internal "eight" shape. The angle of movement of your legs should be about 30-40cm up and down in the water.

2. When lifting up, the thighs drive the entire legs, relax the calves, and lift them close to the water.

3. Then start to press down from the thighs, bend the knees naturally, and gradually transfer the force to the calves, driving the calves to press down.

4. Finally, when the thigh and calf are in a straight line, the force is just transmitted to the foot plate, that is, the foot plate transmits the force to the water, and the reaction force of this force is immediately used to lift the entire leg.

Summary of freestyle kicking: The whole set of movements is like whipping, and the maximum force is just at the tail end of the whole leg, that is, the flat foot, and the two feet swing alternately, creating a continuous The power of the "eight" figure in Chengnei just concentrates the power together to produce the maximum propulsion force.
