When swimming, how does the kick of the leg generate forward thrust? Who can describe it in detail_ Hundred
As far as freestyle is concerned, the propulsion generated by kicking is limited, because straight leg kicking is mainly to maintain body balance, but kicking will promote the body to rotate around the axis of cervical vertebra. As long as the streamline of the body is maintained, certain resistance can be overcome in the waterSwimming and kicking  kicking produces limited propulsion, which is similar to the principle of screwing screws into the wall to maintain the rigidity of the bodyI would like to ask the masters of swimming, what is the coordination of leSwimming and kicking  kicking produces limited propulsiong stroke, arm stroke and ventilation in freestyle_ Baidu
1. You can use the hand board to practice kicking 2 freestyle. When you lie prone on the water to form a streamline, the muscles of your back and buttocks maintain appropriate tension, keep your head stable during swimming, and naturally rotate your trunk around the longitudinal axis of your body in a rhythmic way for 35 ゜ ~45 ゜. Freestyle leg although freestyle leg movement has certain propulsionHow to draw water when learning freestyle
Are you doing the right thing now? Please let us enter the world Swimming and kicking  kicking produces limited propulsionof drawing water and understand its benefits to our swimming. The role of kicking movement in freestyle training kicking and the stroke of both arms coordinate with each other to promote the forward stroke of both arms. Driven by this force, the body moves forwardHow to kick the water when swimming
Kicking method of swimming feet: the legs should be retracted with knees bent. The strength should be small when retracting the legs. The heels should be close to the hips, and the legs should be close to the thighs as much as possible. It is best to be within the projection plane of the thighs when retracting the legs, so as to reduce the resistance of retracting the legs as much as possible; The best position after leg retraction is that the lower leg is almost vertical to the horizontal planeShould your legs be straight when swimming freestyle
If you always think about whip like movements, you may overdo it and turn it into a bent leg beating, which will increase the resistance. "Straight but not stiff, the thigh drives the calf" is my more than ten years of swimming teaching experience. I often say this to students. Just think so when you practiceHow do you get into the water when swimming and diving
For example, the range of water drawing is about 30 ~ 40 cm, and the instep can be pressed down against the water surface. The two legs should be coordinated alternately. The strength should be average and the range should not be too large. Keep knees and ankles soft. Don't lift your legs too high. Just keep your instep close to the water. Don't bend your knees too high from the waterSwimming into the water kick skills
The kick of freestyle is one of the power sources of freestyle swimming, and the other power source is the alternating stroke of both hands. Let's introduce the kick of freestyle. In addition to propulsion, the purpose of kicking is to raise the hips and legs, keep the body in a low water resistance position, and reduce the resistance brought by the legsThere are several ways to swim
Breaststroke - exercise leg strength. Both the freestyle and backstroke legs are whipped up and down. Only the breaststroke is a clamp. The former can make the legs longer, while the latter uses the quadriceps femoris more. Therefore, it is very effective to exercise the strength of the legs. Butterfly - exercise chest strength. In the butterfly stroke, the arms pull inwardWhat is the proper angle of the freestyle leg
The kick of the freestyle leg is almost vertical to the horizontal plane. From the vertical plane, the distance between the two legs is about 30-40 cm, and the bending angle oSwimming and kicking  kicking produces limited propulsionf the knee joint is about 160 degrees. During swimming, the feet should be close to the level when the legs are pumping upward; When drawing water downward, it should not exceed the lowest part of the body in the water
