Why swimming can help you lose weight

When a person swims in water, his arms paddle and his legs kick or push the water, so all muscle groups in the body participate in the exercise, which can give the muscles of the whole body a good exercise. In addition, when swimming, because the density (in other words, resistance) and heat transfer performance of water are greater than those of air (the thermal conductivity of water is 26 times greater than that of air, which means that at the same temperature, the human body loses heat in water more than 20 times faster than in air, which can effectively consume heat), the body consumes more energy in water than on land. The supply of this energy is supplemented by consuming sugar and fat in the body. Regular swimming can gradually remove excess fat in the body without becoming obese.

Free swimming breathing techniques

1. Turn your head while turning sideways. When swimming freestyle, the best angle is to turn sideways at about 45 degrees. However, if you turn your body without turning your head, it is difficult to expose your mouth above the water. Therefore, if you only turn your body without turning your head, you will not be able to breathe properly and you will not be able to breathe.

When swimming freestyle, many beginners either turn sideways at too small an angle, or do not turn sideways at all. Even if they turn their heads, they cannot expose their mouths above water to breathe.

So when you do a sideways turn, you can turn a little more, and then turn your head a little to expose your mouth completely above the water to breathe. You can also turn your head a little more, so that your face turns diagonally upward, which can also expose your mouth completely above the water.

2. Do rhythmic breathing, exhale slowly and continuously. Why is it natural for people to exercise on land? It is because they can do regular breathing exercises and exhale continuously when they breathe. But in the water, holding your breath is also very natural and normal, but holding your breath can actually make people feel nervous. So to get more relaxation from the rhythmic breathing technique, you need to exhale slowly and continuously.

Bilateral breathing is a different matter. You need to hold your breath once in the middle of three arm strokes. Generally, when breathing unilaterally, you cannot hold your breath as soon as your head enters the water. When you are about to inhale, you should exhale all the air at once.

How many kilojoules does swimming consume?

Swimming consumes about 1000 kilojoules per hour. Swimming is a process in which a person floats upward under the buoyancy of water, and uses the buoyancy to move his limbs in a regular manner. With the development of swimming, swimming is divided into two categories: practical swimming and competitive swimming. Practical swimming is further divided into sidestroke, diving, reverse breaststroke, treading water, rescue, etc.; competitive swimming is divided into breaststroke, crawl, backstroke, butterfly stroke, and freestyle. The levels are: Level 3, Level 2, Level 1, Master, and International Master.
