What are the benefits of wearing a swimsuit when swimming? The advantages and disadvantages of swimming

Swimming is a whole-body sport that involves more muscle groups than other people in metabolic energy supply. Regular swimming can increase the strength of respiratory muscles and improve the function of the respiratory system. It also increases lung capacity. People usually wear swimsuits when swimming, so what are the benefits of wearing swimsuits? Let's learn more about it below!

The benefits of wearing a swimsuit when swimming

Most swimming trunks are made of nylon and spandex. Swimwear requires good fit and is not easy to retain water. Otherwise, it will hold water and absorb water when swimming. Ordinary underwear is usually made of cotton, which is easy to retain water. How can you swim with heavy water pants? In addition, wearing underwear will be washed away by water, because the waistband of underwear is mainly elastic, and the elasticity in water will be particularly small due to the resistance of water. Therefore, as long as you feel comfortable in the underwear, it will definitely fall off when swimming in the water. It is not recommended to wear underwear for any activities in the water.

Because of the material, most underwear is made of cotton, which will be affected by water.

Make your underwear more transparent, which means it is easy to show your underwear. So you should wear professional swimming trunks when swimming.

The pros and cons of swimming

Benefit 1: Improve the function of the cardiovascular system

Overcoming the resistance of water when swimming requires more energy, which speeds up the heart rate and increases cardiac output.

If you persist in long-term swimming exercises, the volume of the heart will increase, the myocardium will contract more powerfully, the resting heart rate will slow down, the stroke volume will increase, the blood vessel walls will thicken and become more elastic, and the efficiency of the cardiovascular system will be improved.

Benefit 2: Improve the function of the respiratory system

The density of water is more than 800 times greater than that of air, and the pressure on people in water is much greater than that in air. This is why beginners find it difficult to breathe in water.

Because the pressure on the chest and abdominal cavities increases in water, this forces the respiratory muscles to use greater force to breathe.

Therefore, regular swimming can increase the strength of the respiratory muscles, improve the function of the respiratory system, and increase lung capacity.

Benefit 3: Improve the ability of the muscle system

Swimming is a whole-body sport that involves more muscle groups than other athletes in metabolic energy supply.

Because swimming in water requires overcoming greater resistance, and swimming is a cyclical exercise, long-term exercise can improve muscle strength, speed, endurance and joint flexibility. And effectively improve flexibility. Benefit 4: Shape a healthy body

Influenced by the way the muscles work in swimming, swimmers generally have a slender figure, broad shoulders, flexible waist and a well-proportioned body shape.

Benefit 5: Improve the mechanism of body temperature regulation

Since the temperature of water is generally lower than the air temperature, regular swimming can improve the body's ability to regulate temperature, making it more able to withstand changes in external temperature. Winter swimming in particular can have a particularly significant improvement in this regard.

Benefit 6: Swimming consumes a lot of calories

Since the resistance of water is greater than that of air, physical energy is consumed quickly during swimming. The temperature of water is generally lower than the air temperature, and the thermal conductivity of water is dozens of times stronger than that of air. Therefore, people lose heat much faster in water than in air.

Therefore, swimming is faster for losing weight

1. Susceptible to infectious diseases

Because there are many people in the swimming pool, there are also a large number of infectious bacteria in the water. People with poor immunity can easily get infected if they stay in the water for too long.

2. Cause cramps

Swimming for a long time will cause muscle over-tiredness and cramps. In severe cases, drowning may occur, which is also a major disadvantage of swimming.

Of course, as long as we swim properly, the benefits it brings us are greater than the disadvantages. Therefore, when swimming, we should pay attention to various possible problems.

How long should you swim?

The swimming time should be controlled within one and a half hours to two hours, and the training time of athletes is generally no more than about two hours.
