Abstract:

By comparing and analyzing the differences in bone mineral density of college students in different sports, this paper confirms the effective sports for improving bone mineral density of college students. A total of 500 subjects were recruited from 5 universities in Zhengzhou city by the methods of stratified sampling and simple random sampling. According to their sports specialties, they were respectively named the basketball group, volleyball group, football group, badminton group, table tennis group, tennis group, aerobics group, sports dance group, wushu group and control group. Each group had 50 people, half male and half female. The subjects are all from Henan province and are of Han nationality. The bone mineral density of the 1-4 lumbar vertebrae (L1-L4), the femoral neck of the hip, and the whole hip were measured by dual-energy X-rays. SPSS 20.0 was used for statistical analysis of the obtained data. The comparison between genders was performed by t test of independent samples, the comparison between groups was performed by F test, and the multiple comparisons after the event were performed by the S-N-K method. The results showed that there were gender differences in bone mineral density in all groups. Specifically, the bone mineral density of L1-L4, femoral neck and total hip of male students was higher than that of female students, and the above differences were statistically significant (P<0.05). The male and female L1-L4, femoral neck and total hip bone mineral density showed significant differences between groups (P<0.05). The bone mineral density of male and female L1-L4 and femoral neck in the basketball group, volleyball group, badminton group and aerobics group was higher than that in the wushu group, football group, dance sports group and table tennis group, and the above groups and the tennis group were higher than the control group (P<0.05). The total hip bone mineral density of boys and girls in the volleyball group, tennis group, basketball group, badminton group and football group was higher than that in the wushu group, sports dance group and table tennis group, and the above groups and the aerobics group were higher than the control group (P<0.05). The results suggest that basketball, volleyball, football, badminton, table tennis, tennis, aerobics, sports dance and wushu sports can improve the bone mineral density of college students, and different sports may have different effects on the bone mineral density of the lumbar spine or hip, among which basketball, volleyball and badminton have relatively better effects.

Key words: sport projects, college students, bone mineral density, lumbar vertebra, hip
