First, the factors affecting the teaching effect of aerobics in colleges and universities under the background of the new era
(1) student level
First of all, physical fitness. The physical quality of contemporary college students has generally declined. When carrying out aerobics teaching, we should strengthen students' physical quality training in combination with this situation and promote the improvement of students' physical quality. In the process of learning aerobics, students need to have good physical qualities, including strength, speed, flexibility and flexibility. However, college students generally lack physical exercise in life, and their overall physical fitness is not strong. At the same time, their imitation ability and coordination ability are also very poor. When doing aerobics exercises, there are often many problems, such as being stuck, deformed, not in place, not strong enough, etc. It is difficult to achieve the action effect and action requirements in aerobics learning, which has a bad influence on the overall teaching.
(2) Teachers' personal qualities
Teachers have a great influence on students, and their personal qualities play a decisive role in the teaching effect. The level of teachers in aerobics teaching in some colleges and universities is uneven, and the technical level still needs to be improved. As far as aerobics teaching is concerned, teachers and students need to complete it together. Teachers should have a leading position in the whole teaching and have good professional ability and level. On this basis, the teaching quality can be fully guaranteed.
Second, the quality improvement strategy of aerobics teaching effect in colleges and universities under the background of the new era
(1) Build a relaxed and pleasant teaching environment.
In the process of aerobics teaching, in order to make teaching more effective, learning equipment and learning venues should fully meet the needs of the times. Under the condition of advanced equipment, students' awareness of learning aerobics will be significantly enhanced and their attention will be more concentrated [8]. In this process, students can not only learn the knowledge and skills related to aerobics, but also feel the novelty of aerobics, so teachers should pay attention to creating a relaxed and happy teaching environment.
(2) enrich the teaching content
Aerobics teaching activities carried out under the traditional mode have been difficult to meet the actual development needs of students. Aerobics activities should embody new content, new era and new atmosphere as much as possible, so as to avoid students' feeling of being boring, boring and outdated when studying. In practical teaching, we can embody the diversity of content and ensure the vividness of form through fitness dance. As far as accompaniment melody is concerned, we can choose some Tik Tok pop songs. At present, most students have the habit of playing Tik Tok. Being familiar with songs can make students feel intimate when learning aerobics, and can also meet their individual needs in the learning process.
