ABSTRACT
Objective To explore the influence of muscle and fat distribution on sit-up ability of female college students. Methods A total of 1560 female students majoring in non-physical education in a Guangxi University were randomly selected. Body composition was measured by the bioresistance antibody component meter. According to the National Physical Health Test Standard, the height, weight and sit-ups of female college students were measured. The students were divided into four groups according to the score of sit-ups:0, P<0.05). Compared with other parameters, the correlation coefficient between trunk muscle mass and sit-ups was the largest. Conclusion The distribution of fat and muscle has different effects on sit-up ability. Female college students' sit-up ability is greatly affected by subcutaneous fat and trunk muscle, and has nothing to do with visceral fat.
