Hands on the pool, feet backward, back to the toes can support the body can, eyes forward.

Floating on the edge of the pool, the whole body relaxes and then inhales y, closes the breath and lowers the head, the chin to the collarbone, the elbow joint presses on the top of the ear to do passive floating. Open your eyes, when the body floats smoothly on the surface of the water after holding 5-10 seconds, and then slowly exhale, feel the body slowly sink into the water, repeat the exercise.

The degree of floating in the water is very important to the swimmer, floating high, not only is conducive to the smooth completion of breathing and air arm movement, but also can reduce the body part of the cross-sectional area of the water, so as to reduce the resistance of the water to the body. The first thing you need to do is to breathe well.

The inhalation should be sufficient, and the inhalation action should be fast.

After inhaling there should be a short phase of closing the breath and then begin to exhale.

Exhale relatively slowly, and inhale immediately after exhaling, with no pause in between.

The head and upper body should not be lifted too high during inhalation.

Move your arms quickly in the air.

The sinking of the human body in water is also affected by gender, age, and developmental status:

Men, who are more muscular and have a larger percentage of muscle tissue to their body weight, sink easily in water.

Women and body fat fat accounted for a large proportion of body weight, easy to float in the water.

Elderly people have less gelatinous content in their bones and a larger proportion of their body weight, and sink easily in water.

Children and adolescents are not fully ossified, more water and gelatinous components in the bone, muscle moisture content is also more, the body specific gravity is smaller, easy to float in the water, which is very favorable for children and adolescents to learn to swim well.
