Line dance is a new international sport dance. The specific content of this kind of dance is as follows. First of all, we need to select music, match dance steps with suitable music, and maintain free standing positions. Whether in a row or in a circle, we can achieve the popular dance fitness participated by body which combines music, dance and other artistic forms. At the same time, the relevant people participating in dance are required to follow the prescribed dance movements. Each piece of dance music of line dance basically has its own rhythm, and varies by rhythm. It can be found in the teaching practice that many college students can complete dance movements in the normal physical education course and master the skills of line dance in repeated training after the public physical cause is offered in colleges and universities. Some of the students’ line dance movements are not standard enough due to their lack of strength, speed and coordination ability. The main reasons include the poor sense of rhythm of music, lack of confidence in dance, rigid body movements and so on. However, in fact line dance can effectively strengthen college students’ physical function, cultivate their music literacy and enhance their psychological quality. Therefore, this paper further strengthens college students’ line dance skills through the study of these three elements.
2. Research Objects and Methods
2.1. Research Objects
Two classes of college students in a university were taken as the research objects. Among them, class A was used as the experimental object, and class B was used as the control experimental group. Each class had 30 students. Basic conditions of subjects (see Table 1).
In the experiment, the questionnaire and statistical analysis method were used for study, and both classes had some dance experience. Such experiment needs to take a semester as the experimental time. A sports course of line dance is offered once a week, and line dance sports are carried out normally according to the time of college sports course. Before the experiment, we needed to collect the results of the physical quality and health test of Class A and Class B, and tried to keep the basic physical quality and physical ability level of the two groups consistent  .
2.2. Research Contents
The main contents of the experiment include three aspects. First, the physical quality. The control group only did some stretching exercises according to the original teaching method, learned normally and repeated training according to the teacher’s dance steps, and relaxed properly at the end of the experiment. The experimental group warmed up by leg-raising and jogging in the warm-up stage, which could improve coordination ability of the body. Then, according to the basketball training movements, they ran back and forth, followed by line dance  . Basically, each person needed to complete several groups of sit-up and relax after completion.
Second, in terms of music training, the control group needed to play the dance music in line dance according to the routine situation, but the students’ sense of music rhythm should be observed, and students needed to imitate constantly, so as to better follow the music rhythm. In teaching in the experimental group, the style and rhythm of music were analyzed, and training of the rhythm of music was provided constantly, so as to help students better grasp the rhythm of music and experience the mood of music in many dance movements.
Table 1. Basic conditions of experimental subjects.
Finally, in terms of psychological quality, normal teaching was still provided to the control group. After completing the teaching task, the problems of students existing in the training were corrected. In addition to the normal evaluation, no other training was provided. In the experimental group, training was provided to students by group after the completion of the teaching. At the same time, a number of simulation competitions were made. At the same time, students needed to correct and evaluate their own training results  . Students need to be encouraged in training, so that they could perform in the community, gradually accumulate more performance experience, and have better psychological quality.
After a semester of experiment, the physical quality of the two groups of students was evaluated. The specific indicators of this evaluation meet the requirements of the Ministry of Education for students’ physical education evaluation. According to the relevant requirements of students’ health and physique, the results of the evaluation were obtained scientifically and reasonably. In addition, a questionnaire survey should be made. According to the actual cognitive level of students in line dance and rhythm training, the survey was made to find the effect of mastering of this sense of rhythm, and check whether the students’ physical quality had changed. The specific test content includes students’ feeling of body change, sports skills, actual physical conditions, whether the student is strong or not, etc. The main result of this questionnaire survey is the satisfaction of college students to their physical conditions. Then, a dance song was selected as the most important music used in the examination. The final evaluation was made by fixed judges on two groups of students  .
3. Research Results
3.1. The Effect of Improvement of Physical Quality on College Students’ Mastering of Skills of Line Dance
Comparison of Physical Quality between Control Group and Experimental Group
Adoption of Table 2, it could be found that there was no significant difference in physical quality and ability between the control group and the experimental group before the experiment, which basically met the requirements of the experiment. After a semester of training, the physical quality of two classes improved significantly, but comparing the two groups it could be found that the experimental group (Group A) had more obvious physical improvement. In the physical training such as 800 running, long jump and sit-up, it could be found that the physical quality of the experimental group had been significantly improved, so we could basically conclude that in line dance increasing the content of physical quality training could significantly improve the physical quality of students, so it has a positive effect  .
3.2. The Effect of Improvement of Music Literacy on College Students’ Mastering of Skills of Line Dance
Statistical Results of Post-Experiment Questionnaire in Control Group and Experimental Group
So the results of the survey in Table 3 show that it could be found that many college students admitted that music could effectively improve their skills in practice of line dance. The focuses were the need for rhythm training and the improvement of the performance of line dance by understanding of music. It was obvious that the experimental group was more supportive, while the control group was less supportive. After the experiment, the line dance test on college students continued. The results of the related tests showed that the experimental group to which music knowledge was explained could have a deeper understanding of music and a better sense of rhythm. In addition, the experimental group also had bigger expressive force and tension, and good aesthetic feeling. In conclusion, the improvement of music literacy is of great significance for college students to master the skills of line dance.

3.3. The Effect of Improvement of Psychological Quality on College Students’ Mastering of Skills of Line Dance
At present, the mental health of college students has been paid attention by the society. To a great extent, mental health directly affects the healthy growth of college students. In the stage of college students, teenagers change into adults. Facing many psychological changes, there are great moral problems in self-psychological adjustment and control caused by lack of experience. Therefore, they lack adjustment ability when facing economic and emotional pressures, leading to serious psychological impact. Therefore, it is easy to have very intense psychological contradictions. By comparing the test results before and after the beginning of the experiment between the control group and the experimental group, it could be found that students’ physical self-esteem and physical attraction improved significantly  . However, comparing the training results of the control group and the experimental group, it could be found that the experimental group was better than the control group in all the items, and the experimental group had a more significant improvement. This can show that the psychological quality of the students in the experimental group significantly improved.
Finally, the results of college students’ line dance test were compared. In the results, it could be found that in the items of college students’ line dance sports such as movement proficiency, opening modeling and performance in line dance the psychological quality of the experimental group had significantly improved, so the results of the experimental group were obviously better than those of the control group. Therefore, we can see that in the evaluation of line dance the experimental group was more confident and had bigger expressive force. In actual training, their movements would not be uncoordinated because they were too nervous. In the line dance performance of the experimental group, they showed better vitality, and the performance was more fluent. Students were obviously relaxed, and had better aesthetic feeling. Through these experiments, it can be found that good psychological quality can effectively help students complete the line dance, so that they can really integrate body and mind into the dance movements and show better results.
