1. Assist athletes to understand correct movement techniques and speed up the process of mastering movements. When the practitioner starts a new movement, because he has no technical experience and has not created a clear technical definition in his mind, he can't do it or the movement doesn't go smoothly, which leads to various technical inaccuracies. At this time, it is necessary for the coach or teacher to give necessary protection and help (the key is to give boosting assistance) to help them perform the action correctly, and then understand the appropriate technical points and create an accurate and detailed definition of the action. Only in this way can the practitioner speed up the process of mastering the movements and master the movements faster and better.

2. It is helpful to correct incorrect movements and improve the quality of movements. When there are various problems in the whole process of learning and training actions, the most common and effective correction methods are oral correction and auxiliary training, or correction according to protection and auxiliary methods such as power, data signals and markers. For example, the special designated movement of uneven bars "one foot turns 360 degrees" can help correct the deviation of the center of gravity from the supporting foot and the wrong turning orientation according to the hip and rubbing skills of the two-handed tractor. Another example is that when uneven bars kick back too early or too late, the coach usually reminds athletes of the appropriate time to kick back according to data signals such as words or applause.

3. Reasonable prevention and reduction of accidents. Because gymnastics movements are complex, difficult and thrilling, all kinds of accidents may occur in classroom teaching practice and even in competitions, such as flying out of the equipment, hitting the equipment, or falling off the equipment. Therefore, it is the responsibility that every gymnast must attach great importance to and bear to give the needed protection and help at any time and place and maintain the safety of the practitioners.

4. It is conducive to enhancing the feelings between teachers and students and shaping the spirit of unity and friendship. It can be said that every movement mastered by gymnasts is studied hard with the help of coaches, which makes teachers and students work closely together. According to this kind of cooperation and mutual cooperation, students' mood can be improved. In classroom teaching practice, athletes are often allowed to protect and help each other, which can not only improve the hardness and exercise intensity of the class, but also shape the professional skills and problem-solving ability of college students, and also shape the altruistic spirit of unity and friendship of students. Protection and function are two different definitions, but they cannot be absolutely separated. Their influence is very close. There is help in protection and protection in aid.

To put it bluntly, "protection" refers to various safety precautions taken to avoid accidents, which must be implemented at all times. And "assistance" refers to various teaching methods that are beneficial to athletes' correct movements, such as power assistance and data signals. When the practitioners use their movements flexibly or at the beginning of the game, they will not support them strongly. People often say "out of insurance", specifically "out of help", mainly to get rid of booster assistance and equipment assistance, and protection needs to be re-implemented. As long as there is training, there should be protection. Protection must be implemented at all times and guaranteed everywhere.
