From childhood to adulthood, the exercises we do at school and the sports we usually do are all in the form of 8 beats. Why? On the one hand, all monosyllabic words within ten are more conducive to the rhythm of shouting passwords. English is basically the same, so I guess it's a way to copy foreign countries. But the way to adapt is a good way. The second reason is that we should pay attention to balance in fitness. Actions can be divided into left and right, up and down, back and forth or back and forth. So it must be even. The third reason is that some movements are compound, such as up and down, back and forth, upper limbs and lower limbs, and most of them take four beats as a complete movement. The fourth reason is that rhythmic gymnastics is aerobic exercise, and the movements need to be stopped properly. For example, the left arm completes the action and the right side does it again, which is actually a short rest for the left limb. If the time is too short, such as two beats and one change, it will be too frequent, making the body feel nervous and become anaerobic. Most sports and art projects will be used in the process of study and training. Eight beats? Set the password. The beat and action in the password correspond to each other. From the beginning to the process of mastering the movements, we should count the passwords to practice the movements, so that students can learn to use them? Eight beats? Making passwords can greatly improve the efficiency of action learning, and after class, you can also extend what you have learned in class to other similar sports and art projects in your life. With the strong support of national policies, sports art project courses are developing vigorously in Guangxi universities, and more sports art projects may enter Guangxi universities in the future. Eight beats? Studying the present situation of password teaching, finding out its existing problems, and putting forward corresponding solutions are conducive to improving the physical quality of China people and training their sense of rhythm. Maybe eight beats is not the best way to follow, but practice has proved that shouting the password in the form of eight beats is the most suitable choice.
