RESEARCH ON THE APPLICATION OF SPORT DANCE IN COLLEGES AND UNIVERSITIES IN THE HEALTHY DEVELOPMENT OF SPORTS

Abstract

ABSTRACT Introduction: Immunity is closely related to health. When the body's immunity is strong, it is healthy. On the contrary, various diseases appear. Sports dance is an entertainment and fitness sports project that integrates sports, music, aesthetics, and dance, the body movement dance as the necessary content and two-person or collective exercises as the primary form of exercise. Studies have shown that long-term adherence to Tai Chi exercise can significantly increase the serum immunoglobulin IgA, IgG, and IgM levels. Objective: The paper explores the effect of physical dance exercise on serum immunoglobulin and T lymphocyte subsets of college students. Methods: The thesis randomly selected 16 male and female students in the first-grade physical dance optional course of public physical education as the experimental group. They performed physical dance exercises three times a week, 40 minutes each time, and the training intensity was controlled at a heart rate of 135-150 beats/min. Ten weeks; besides, 16 male and female students in the first grade were selected as the control group, and no physical dance exercise was performed; all the subjects were drawn from the elbow venous blood on an empty stomach at the same time before and after the experiment to measure serum immunoglobulin and T lymph Cell subpopulation content. Results: After ten weeks of sports dance training, the serum immunoglobulin IgG of both men and women in the experimental group increased significantly (P<0.01), and the CD4+% and CD4+/CD8+ ratio of T lymphocyte subgroups showed extremely significant and significant increases (P <0.01, P<0.05), serum IgM tended to increase, IgA, CD8+% tended to decrease, but there was no significant change. Conclusions: Long-term physical dance exercise can improve the body's immune function. Level of evidence II; Therapeutic studies - investigation of treatment results.
