2, leg movements: the leg movements of treading water are almost the same as those of breaststroke legs, but it should be noted that the leg movements are smaller. When the leg is retracted, the knee joint can be everted, and when the leg is kicked, the knee joint is pressed internally, and the lower leg and the inside of the foot are clamped at the same time, and the legs are straight forward to start the second leg retraction action. After skilled movements, you can also carry out the movement technique of alternately kicking and holding water with your legs.
3. Arm movement: the arm is slightly bent, and the water is pressed outward in the front direction of the body, and the movement range cannot be too large. Outward, palm outward, feeling separated from water; When you are inward, your palms are inward and downward, which feels like squeezing water. Touch and press inward to shoulder width to separate. The route of the two palms touching the water is in a double "︵" arc.
4. Coordination of arms, legs and breathing: The coordination of arms and legs should be coherent and coordinated. Generally speaking, when the legs push and pinch water, the arms touch and press the water outward, and when the legs retract, they touch and press inward. Breathing should follow the arms and legs naturally. Inhale when pedaling (arms outward); Exhale when you retract your legs (arms inward). You can breathe once in one action or once in several actions.
5. When swimming on water, you can change the swimming direction by using different lateral directions and pedaling directions of your body. Forward, and lean forward slightly, push your feet slightly to the side and catch the water, and push your arms slightly thicker, and vice versa.
6. When you step on the water skillfully, your body can float with your legs, so that you can hold things freely on the water with one hand or both hands. One swimming method is that people stand upright in deep water and lift their legs up and down alternately, so that they can move forward without sinking.
