How far can freestyle kicking go?

Freestyle kicking is that the thigh drives the calf, and the legs clamp the feet slightly inward. In addition, due to the characteristics of muscles, everyone kicks different times. Some people kick twice, some people kick five times, and some are even higher, depending on their leg strength. A round of arm stroke means that the left hand draws a circle and the right hand draws a circle. During this period, how many times did you kick? Each athlete has different time according to his leg strength. Stroke once on each arm. Generally, when sprinting, you will kick 5 times and 2-4 times in the middle. Feeling tired of legs should be the reason for kicking more times. More strength of freestyle comes from arm strength. Legs are too far from the heart, and kicking them takes too much energy. Don't kick too much unless your legs are strong, which will increase your consumption. Get twice the result with half the effort. In addition, the calf can't swing casually, and the thigh is needed to drive the calf to exert force. Besides, I'm not always nervous. When I fell down, I tried my best. I was relatively relaxed when I went up. It is easy to get tired and the effect is very poor.
