How to breathe when swimming? Which swimming style is the fastest and the least labor-saving?

When kicking, put your hands together as close as possible, and at the same time lower your head and exhale through your nose. When closing your legs, press water with your hands under your sides, and look up at the same time (using the buoyancy when pressing water with your hands to look up), and open your mouth to inhale. Inhale and exhale, and repeat the cycle.

1. First, stand in shallow water and repeatedly practice upper limb and head movements (with breathing); ?

2. Open your mouth and inhale-open your mouth as wide as possible and inhale quickly, but don't suddenly inhale air into your lungs at first, but take a big breath in your mouth and use your mouth as a "transit station" and then inhale. The advantage of this is to prevent ten thousand heads from being lifted not high enough, or when the water is rippling, the mouth opens and sucks in water instead of air, which is easy to choke. ?

Exhale through the nose-when the head is submerged, the nose will easily enter the water. Breathing through the nose can effectively prevent the nose from entering the water, and you can inhale when you look up, shortening the time of breathing when you look up, and your neck will not be tired, which is conducive to speeding up swimming. ?

Practice and coordinate the above actions, and you will have a sigh of relief. The key is not to be nervous. Take your time. If you are nervous, you can't do it well, and people are easy to sink and choke. The movements stretch naturally and are easy to coordinate. ?

It can be summarized as two sentences: "kick, lower your head and exhale, and the rower raises his head and opens his mouth to inhale;" Kick your legs quickly and forcefully, and your legs should be a little slower and easier. " ?

Freestyle is the most labor-saving swimming posture. Reasonable structure, small resistance, uniform and fast speed.
