The results of the survey (Table 1) show that students' motivation to participate in aerobics options is varied.The top four are fitness weight loss (37.9%), body building (27.9%), personality building (22.7%), and communication (11.5%).Through our case study, it is found that the research objects of college students first focus on fitness and weight loss, because the aerobics exercise can achieve the purpose of enhancing physical fitness, promoting health, weight control and pleasing body and mind.Secondly, shaping the body is also a great concern of college students.Now the university aerobics special course using the "public fitness regulation action" is through the study of six sets of aerobic dance, can improve the state of body beauty, improve the human body to the body control ability and performance ability.
National aerobics dance level rules aerobic dance part, using scientific, effective aerobic training way can promote students body blood circulation, improve the students 'cardiopulmonary function, improve students' muscle flexibility ductility, can let the students keep good body form, improve the students' inner temperament, let students in various activities of more confident, more intellectual elegant, to meet the aesthetic needs of college students.Social communication is also an important aspect of physical and mental health.College students, who are always under the pressure of study, may form a shy personality who does not love to communicate with others, which is not conducive to the cultivation of healthy personality.
And aerobics teaching in colleges and universities is in the form of collective teaching, need interaction between teachers and students, interaction between students, sometimes use small group study, review or even group test teaching form, in the teaching process can cultivate the students' teamwork consciousness, through mutual error correction action memory together, to show the student enthusiasm, make public, energetic spirit, let the student in a more friendly love, help each other, further enhance communication ability can enhance the social interaction, let college students in the intense learning can fully release self, express themselves.

Students' Love for Aerobics Projects
Research found that college students are generally interested in aerobics class, 58% of students think they are very interested in aerobics course, 29% of students think themselves interested in aerobics, and 13% of students think they have no interest in aerobics, because need to complete physical education class credits, so just chose a sport.

Students' Cognition and Teaching Status of Calisthenics and National Aerobics Dance Level Routines
The study found that the students contacted aerobics mainly through the first impression brought to the students through new media, middle school physical education and watching aerobics performance (Table 2), so they chose the special course of aerobics, hoping to master more knowledge and learn more content through the study of aerobics special course.The application of new media technology in the teaching of aerobics in colleges and universities has been relatively popular, and its main application tools include PPT, video, music, WeChat and Weibo, etc.The author believes that new media technology can improve the teaching interest, interactive and learning effect, but there are also some problems, such as lack of professional technical support and guidance, improper use will affect the fitness effect, new media teaching resources and update; so students through new media, watching performances and other ways, often only a preliminary impression of aerobics.Real aerobics learning is a complete teaching process, in aerobics teaching, in addition to let the students master aerobics routines, also let the students understand the aerobics basic theory, basic technology, basic skills, competition rules, knowledge and skills, understand through aerobics exercise to promote human body health, shape form, edify sentiment, show themselves.

Students' Liking Degree for the Prescribed Routine Movements
In a survey of 419 students who have learned the National Exercise Level Action (see Table 3), 36.3% of students liked the aerobics level routine, 30.5 students liked it, 19.3% were average, and 13.8% did not.Research shows that the level of aerobics routine is still more popular with college students.

Understand the reason why students do not like the routine, but also help the teacher in the future teaching, such as the action is difficult to remember, teachers can use the segmented teaching method, the whole set of actions can be divided into many times to learn, each time to strengthen the review, so that students really master.

Determine the Arrangement Difficulty and Exercise Intensity of the Routine
The study and promotion of aerobics, the difficulty of its arrangement and the intensity of exercise are very important factors.The arrangement is too simple, repetitive and less intense, and the students will feel boring, monotonous, and have no enthusiasm to learn.On the other hand, if the movement arrangement is too complex and the difficulty is too high, students will lose confidence and be unwilling to practice actively."National national aerobics dance level regulation action" a total of six levels of (set) action, choreography difficulty and exercise intensity are different: usually aerobics special class students between the dance skills, physical quality have a large gap, a class at the same time to teach a set of action is still a gap.Usually like aerobics, good physical quality of the students feels to learn quickly, very simple, and even feel the exercise intensity is not enough; and the poor physical quality of the students feel too complex, the intensity is too big, accept the difficulty, practice is not interested, no classroom should have passion, so the teaching content is difficult to implement, affect the national aerobics dance level of action promotion.According to the interviews of experts and those of students' survey, most teachers and students think that the first and second level movements of the prescribed routine are relatively simple, more suitable for grade one students to learn; the third and fourth levels is more suitable for grade 2 students to learn; grade 5 and grade 6 movements, mainly instruments, are not suitable for teaching.The author thinks that we can divide the "national aerobics dance level regulation action" into several stages: level one, two level action for the first stage (primary stage); level three, four for the second stage (intermediate stage), five, six for the third stage (advanced stage).Different schools, different classes, can according to their own students 'situation (physical quality, interests and acceptance ability) to arrange students' teaching tasks.

The Importance of the Relevant Department Leaders of the School
To ensure the good implementation of action, in addition to the joint efforts of teachers and students, the attention and support: Shanghai Maritime University is one of the few test sites in the Shanghai area, and a lot of manpower and material resources, school leaders at all levels give green light and strong support; and the performance and competition is an effective way to promote it, and also one of the effective means to promote extensive development.Taking the "National Fitness Dance Level Action" organized in 2016 as an example, our students enthusiastically signed up, 498 students took the exam, accounting for 98.2% of the total number; 483 students passed the corresponding level, and the pass rate was 97%, the exam can increase the enthusiasm and initiative, perform the skills learned in the classroom, increase their confidence, and get physical and psychological exercise.Therefore, in order to carry out the popularization and promotion of "prescribed action" in colleges and universities, we should first strengthen the innovative concept of school leaders at all levels, improve their understanding of sports work, establish the education view of morality, intelligence and body and the talent view to meet the needs of the future society.Secondly, in the sports department and the educational administration and cooperation, the "prescribed action" extensive publicity, promote the popularization of the "prescribed action" in colleges and universities.
