What is football?
Rugby, a kind of ball games, is popular in Britain, America, Australia, Japan and other countries. Originated in rugby, England in 1823, it was originally named Rugby Football, or rugby for short. It is called rugby in China because it is spherical like an olive. Rugby is a city in the middle of England, where there is a Rugby School, which is the birthplace of rugby.
What are the advantages of playing football?
More effectively improve that function of the respiratory system.
Rugby is a combination of running and leg sports. In the process of running, passing the ball, shooting the ball, etc., the depth of breathing will be strengthened, so that more oxygen will be inhaled and more carbon dioxide will be discharged, so that the vital capacity will be increased and the lung function will be strengthened. This is because the main respiratory muscle groups (diaphragm, intercostal muscle, levator costalis muscle, upper and lower serratus muscle, etc.) and respiratory auxiliary muscle groups (scalene muscle, sternocleidomastoid muscle, pectoralis minor muscle, pectoralis major muscle, etc.) strengthen contraction, and promote the development of these muscles, thoracic expansion, chest cavity volume increase, alveoli develop well, respiratory strength increase, vital capacity, lung ventilation and suction (photo) Studies have pointed out that people who exercise regularly have strong physical adaptability, and their breathing appears stable, deep and even, and the frequency is also slow. When they are quiet, their breathing frequency is 7-11 times/minute, while those who do not exercise have a breathing frequency of 12-18 times/minute, and women are 2-3 times faster than men.
Prolong life more effectively.
A ten-year study shows that people who don’t exercise are 42% more likely to die young than those who often play football. 5%。 The reason is that if you don’t exercise, you will accelerate aging in many places, and even get old before you get old. And these people who don’t exercise have lower resistance to cancer, heart and so on than those who play football.
Strengthen the bones of the legs.
Rugby is the best exercise for training legs. In the process of continuous leg exercise, the blood supply of bone is improved due to the promotion of metabolism, and the morphological structure and function of bone have undergone good changes: the bone density is thickened, which makes the bone thicker, the arrangement of bone trabeculae is more orderly and regular according to different pressures and tensions, and the protrusions attached to muscles on the bone surface are more obvious. These changes make the bone stronger and stronger, thus improving the functions of bone in bending, bending, compression and torsion. Insisting on physical exercise can also enhance the strength around the joint, and the joint capsule and ligament are also thickened, thus increasing the stability of the joint; At the same time, physical exercise makes the joint capsule, ligament and muscles around the joint stretch, thus improving the flexibility of the joint.
