Swimming method

In international competitions, there are four swimming styles: breaststroke, backstroke, freestyle and butterfly.

Among the four postures, except breaststroke, which is a backward posture, the main forward force is the lower limbs, and the forward force of the other three postures is the upper limbs.

However, with the improvement of breaststroke technology, athletes generally adopt "wave breaststroke" in the competition. This new posture is the joint action of upper and lower limbs.

Among the four postures, freestyle is the fastest and most powerful.

Butterfly is the second fastest, but it takes a lot of effort and requires a certain physical quality.

The speed of breaststroke is the third, but the wave breaststroke is the most laborious of the four postures.

Backstroke is the slowest position, but it is very powerful because it is convenient for breathing.

The action principles of freestyle and backstroke are similar, but that doesn't mean you can freestyle and backstroke, because the world champions of these two events are not the same person.

Butterfly stroke is a gesture separated from breaststroke, but later breaststroke technology absorbed some connotations of butterfly stroke.

Freestyle mainly exercises shoulder muscles, upper arm muscles and pectoralis major muscles.

Backstroke mainly exercises shoulder muscles and back muscles.

Breaststroke mainly exercises leg muscles, abdominal muscles and upper limb muscles.

Butterfly stroke mainly exercises waist and abdomen muscles and upper limb muscles.

If you want a perfect figure or exercise all your muscles, you must swim in every position ~
