What are the most basic rules of basketball?

The first principle, this principle should be familiar to everyone, because whether it is playing basketball or watching basketball games, everyone knows that basketball is a basic sport of dribbling with hands. This is the first basic principle of basketball, the ball is played with hands.

The second principle is that no matter whether you are walking or running, your head must be dribbling the ball. You cannot run around the court with the ball in your hands. This is the second principle.

The third principle is that athletes can move around the entire basketball court without affecting the opposing players. Because basketball is a sport that involves continuous dribbling, the smoothness of his dribbling is easily affected by the surrounding environment.

The fourth principle is that because they can move around the entire basketball court, players from both teams cannot have physical contact.

The fifth principle is the shooting ring, it must be horizontal and cannot be tilted.

The origin of the three-point line in basketball

The origin of the three-point line The three-point line originated from the American ABI in 1961-63, and was later adopted by the ABA (1967-76). The NBA did not officially introduce the three-pointer until the 1979-80 season. At that time, the three-pointer was just an "experimental product in the routine season". The three-pointer had a great impact on the NBA. By the 1980-81 season, the NBA had fully accepted the three-pointer system, but there were some minor changes in the 1994-95 season and the 1995-96 season. The distance of the three-pointer in those two seasons was 22 feet. (FIBA also introduced the three-pointer in the 1984 international competition. The distance of the three-pointer was 20 feet 6 inches, about 6.25 meters.) So it can be said that basketball did not have a three-pointer at the beginning, and the NBA started using the three-pointer earlier than the international competition. 2. The evolution of the three-pointer NBA did not start using the three-pointer until the 1979-1980 season. Before that, the NBA games had only two-pointers and one-pointers, and there was no three-pointer at all. The shape of the three-point line at that time was exactly the same as it is now, but due to the limited technical level of the players, many people's long-range shooting ability was somewhat different from that of today's players. Therefore, the number of three-point shots and the number of hits were very small. The top five players on the three-point shooting list in the 1993-1994 season had an average of 165 shots per person, and the highest number was only 292. In order to change this situation, the NBA shortened the distance of the three-point line to 6.70 meters in the 1994-1995 season, so many players flocked to it, all wanting to try their hand at the three-point line. As a result, the top five players on the three-point shooting list that season had an average of 258 shots per person, and the highest number reached 425. This situation where everyone can shoot three-pointers is difficult to reflect a player's long-range shooting ability, so the NBA moved the three-point line back to the original 7.25 meters in the 1997-1998 season.

The physical benefits of playing basketball

1. Effectively prevent cardiovascular disease

When playing basketball, the muscles are tense and the heart works harder, the blood supply and metabolism of the myocardium are strengthened, the myocardial fibers are thicker, the heart wall is thicker, the heart volume is larger, the shape is rounder, and the heart beats more vigorously. All of these are also good ways to treat cardiovascular disease. Cardiovascular disease is the number one killer that threatens human life in the world today. According to reports, in my country, the number of people who die from cardiovascular disease also ranks first. A large number of studies have shown that regular basketball can significantly reduce the risk of cardiovascular disease formation and occurrence.

2. Control weight and change body shape

Excessive obesity can affect a person's normal physiological functions, especially increasing the burden on the heart and shortening life. If a person's subcutaneous fat exceeds the normal standard by 15%-25%, then his risk of death will increase to 30%. Basketball can reduce fat, increase muscle strength, and maintain joint flexibility, so it can control weight and improve body shape and appearance.

3. Enhance heart function

Regular basketball exercise can enhance heart function, increase stroke volume, thicken the media of arterial walls, increase smooth muscle cells and elastic fibers, increase the number of capillaries in skeletal muscles, enrich branch anastomosis, thicken and increase the weight of coronary artery ostia, and increase the number of myocardial capillaries, which are beneficial to the blood supply and function of organs including the heart itself. At the same time, basketball exercise can also reduce blood pressure and serum cholesterol levels, which has a good effect on preventing hypertension and coronary heart disease.

4. Reduce the risk of diabetes

One of the characteristics of diabetes is that a person's blood sugar level is very high. If it is not controlled, it will also cause many other health problems, such as impaired vision and kidney deficiency. Regular basketball can control the increase in blood sugar levels, thereby greatly reducing the possibility of an individual developing diabetes.

5. Improve the function of the digestive system

Basketball will increase the consumption of nutrients in the body, enhance the metabolism of the entire body, and thus increase appetite; in addition, it will promote gastrointestinal motility and secretion of digestive juices, improve the function of the liver and pancreas, thereby improving the function of the entire digestive system, providing a good material guarantee for human health and longevity.

6. Regular participation in basketball exercises can improve various physical qualities of the human body.

This is because physical exercise is carried out under special conditions and in a special environment. The organism must mobilize and exert the functions of various organ systems to the maximum extent, such as nerve regulation, enhanced breathing, and accelerated blood circulation. In this way, over time, various physical qualities will continue to improve.
