The world of sports is different so any person can choose his or her favorite sport. Adel, a young girl is crazy about basketball and as a professional, she tells her new friends about the benefits of this amazing sport activity. She wants more young people to play basketball.

Firstly, while playing the game, children have to run, jump, and spring on their feet, bend over, raise their hands, and throw the ball. Therefore, all muscle groups are trained and developed: legs, arms, and back.

Secondly, a child becomes more agile; he or she skillfully owns the body and confidently coordinates all movements. The lungs and heart are perfectly strengthened - they begin to "work like a clock."

To pass the ball, you need a good eye and logical thinking because you should guess where the ball will be, where your teammate or an opponent will locate in the next second. Basketball develops these important qualities very well. In addition to physical qualities, basketball teaches children to control and collaborate with each other.
