In breaststroke, the calf is not separated enough, and there are some inner characters. In fact, when I was swimming, I was already paying attention. It is reasonable to say that the calf is a little sore on both sides of the crotch, but it is ok to do it on land, and I can't find the feel at all in the water. How can I improve? In addition, is there any way to pull the calf apart without causing minor damage to the knee? The widely circulated method of kneeling on the ground with hooked soles seems to hurt your knees. I fell my knee several times and couldn't stand the toss, hehe. Iig China Sports Network replied: Specifically, splitting the legs should mean kicking and clamping the legs, and it should mean that the legs should be retracted to the hips as far as possible. If you feel that your flexibility is not good, you can increase land training, especially leg flexibility exercises. Swimming knee injuries are more common in breaststroke kicking, excessive thigh opening or excessive knee valgus, which leads to sprained medial collateral ligament of knee joint.

Iig China Sports Network replied: Looking up here refers to the height of looking up, whether it is mandatory to look up. This is mainly the technical difference between wave breaststroke and parallel breaststroke. Wave frog technique is to lift the upper body and shoulders, but the head does not have to be lifted deliberately. When entering the water, there is a diving drill, that is, the head is sandwiched between the two arms to reduce the resistance. It is wrong for Gao Quan to look up. Looking up means a flat frog. The flat frog can only breathe with its head out of the water, but can't raise its head. Iig China Sports Network
Question 3: When swimming breaststroke, if you hold your breath underwater, you feel that your body can keep streamlined, your muscles and movements are in place, and you can swim faster, but you will be tired after swimming for a long time. If you exhale underwater, you will feel very loose, especially when you exhale, your waist will collapse, your streamlined feeling will be gone, and your movements will be deformed. What happened? Iig China Sports Network replied: Regardless of the distance of the competition, breaststroke is inhaled once in each movement cycle. Breathing combined with arm and leg movements helps to speed up swimming. Breathing should maintain a certain sense of rhythm in the coordination of breaststroke breathing. Exhale through your mouth in the water, spit it out, then lift your head out of the water and inhale through your mouth and nose. Usually consciously increase the practice vital capacity iig China Sports Network.
