Health guide: it is one of the public hobbies. It is not only a way, but also a way of leisure and entertainment. For many social elites, fitness and relaxation in the swimming pool is a magic weapon. Swimming has the lowest strain rate, so swimming is lifelong fitness. What are the swimmers?

Improve the function of cardiovascular system

Long-term persistence in swimming can increase heart volume, strengthen myocardial contraction, slow quiet heart rate, increase stroke output, thicken blood vessel wall, increase elasticity and improve the efficiency of cardiovascular system.

Improved function

Because the density of water is more than 800 times higher than that of air, people are under much greater pressure in water than in air. Due to the increased pressure in the chest and abdominal cavity in the water, the respiratory muscles are forced to breathe with greater strength. Regular swimming can increase the strength of respiratory muscles and improve their functions.

Ability to improve muscle system

Swimming is a full-body exercise that can improve muscle strength, speed, endurance and joint flexibility for a long time. Correct swimming techniques require muscles to stretch before contraction, which is conducive to continuously improving our flexibility and strength.

Make the proportion more reasonable and shape a healthy figure.

In the process of swimming, it produces resistance with water and has the effect of losing weight. Long-term swimmers are generally slender, with broad shoulders, flexible waist and well-proportioned figure.

Improve the thermoregulatory function.

Because the temperature of water is generally lower than that of air, and the thermal conductivity of water is dozens of times stronger than that of air, people lose far more heat in water than in air. Regular swimming can improve the ability of body temperature regulation, so as to be more able to withstand the changes of external temperature.
