People's jumping ability is mainly related to the characteristics of their muscle fibers. The more white muscle fibers, the better people's jumping ability. White muscle is long and narrow, and its contraction speed is fast, which determines people's speed and flexibility, so it is called "fast muscle". The muscles of basketball, volleyball, high jump and long jump are all white, and the muscles of strength athletes such as weightlifting and boxing are red. Their appearance shows this. Within a certain range, white muscle and red muscle can be transformed into each other, so bodybuilders can achieve their desired muscle types by practicing different jumps. If you want strength and endurance, you can do aerobics. If you want to practice speed strength, that is, explosive power, you can practice high jump, long jump and high lift running more.
