The article will talk about the influence of aerobics on mental health of college students aiming at the fact that mass aerobics haven＇ t developed very well. Aerobics expand the traditional pattern of school physical education, in addition to improve and animate sports classroom atmosphere; students can be fully met the physical and mental demand, so as students can be guided to actively participate in physical exercise, making further promotion of students＇ body and function development; students＇ physical fitness involving coordination, softness, power and endurance can also be fully developed. Students can develop good body posture, shape their physical beauty and performance of actions, cultivate sentiments and further demonstrate the beauty and health of themselves.展开更多
