I think the main stroke of many swimmers is breaststroke, right? When the frog is one or two kilometers in the water, some people must feel uncomfortable and painful in their knees, while others are unharmed and feel nothing.
Does breaststroke kick hurt the knee? How to avoid knee pain in long-distance breaststroke? This is the topic we want to discuss with you today.
Different knee pressures between wide and narrow kicks
Speaking of breaststroke kicks, we must first distinguish between wide kicks and narrow kicks.
For adult swimmers who do not have boy skills, wide and narrow kicks have impact pressure on the knees.
Continuous and excessive pressure on joints is the main cause of joint pain and injury.
①Wide kick: the knees are opened wider than the ankles when the legs are closed, which is common in enlightenment flat frog , and is also a breaststroke kick commonly used by most enthusiasts.
In a wide kick, the pressure of the knee is the supporting opening and closing pressure, similar to our squat on the land, a long, fast and powerful wide kick can cause frontal discomfort and pain in the knee.
②Narrow kick: The knee is narrower than the ankle, and it is common in Beauwa. After the leg is retracted, the calf is continuously pressed like a drop shape.
In a narrow kick, the pressure on the knee resists the resistance and clamping pressure. It is more "anti-human" and squeezes together. A long, fast and powerful narrow kick can cause discomfort and pain on the side of the knee. .
Breaststroke kicks For the athletes of tongzi skills, their flexibility and muscle protection are stronger, and they are less prone to injury, but everyone knows that breaststroke is the longest in a formal competition. The race distance is only 200m. There is no 800 1500 long distance race like freestyle. This also reflects that breaststroke is not suitable for fast long distance races. If you come to a 1500m breaststroke race, the titanium alloy knees will probably be scrapped.
For adult enthusiasts who do not have boy skills, long-distance and fast breaststroke kicks naturally suffer more knee pressure. Whether it is a wide kick or a narrow kick that requires better flexibility, it is easy to make us feel knees. Discomfort and pain.
to reduce the pressure from the knee
So how can you continue to swim in the long-distance breaststroke without reducing the pressure on other knees? How about healthy swimming?
The answer is to push the leg softly and slowly to reduce the pressure on the knee.At the same time enhance flexibility.
Breaststroke kick in the water is to generate propulsion by resisting water resistance to make the body swim forward. The slower the movement, the smaller the water resistance and the weaker the resistance, the knees The pressure is naturally less.
Concluding remarks
If you want to swim breaststroke for a long distance of several kilometers, then it is recommended that all lovers of Buddhism keep healthy and protect your knees to enjoy swimming happily. Of course, it is recommended that you learn other strokes to make yourself richer and more diverse in swimming.
