| Research background and purpose: The psychological health problems of college students are becoming more and more serious,and the proportion of college students who have a tendency to depression in China is high,which is easy to cause the incidence of depression among college students.This problem should be paid attention to by all walks of life.Therefore,exercise improves depression,exercise regulates the intestinal flora and the relationship between intestinal flora and depression has become a research hotspot.Under this background,based on the prospective study of exercise ability and depression risk,this study uses resistance training to intervene in depression Prone to female college students,and simultaneously analyze the changes in the intestinal flora abundance structure,and then analyze the relationship between resistance training and intestinal flora and resistance training and depression.To provide an empirical basis for better verification of the relationship between intestinal flora and depression,and to enrich the treatment of depression.Methods:(1)Experiment 1 uses 862 female college students of Chongqing Nursing Vocational College as the research object(average age 18.7,standard deviation 1.0)to conduct a prospective study between various sports ability levels and depression;(2)Experiment 2 Among the subjects of Experiment 1,54 subjects with depression tendency were selected(the depression score was 50-59 points),and they were randomly divided into two groups for an 8-week resistance training intervention experiment.The two groups were collected before and after the experiment.The subjects’ grip strength and 1 minute sit-up performance,depression level,and intestinal flora were analyzed by collecting stool samples.Results:(1)Results of a prospective study in Experiment 1:(1)Logistic regression analysis showed a significant difference between the prevalence of grip strength(strength)and depression among female college students(P <0.05).(2)Logistic regression analysis showed a significant difference between the prevalence of depression in 1 minutesit-ups(muscle endurance)and female college students(P <0.05).(3)Logistic regression analysis showed that there was no significant difference between other sports ability indicators and the prevalence of depression among college students(P>0.05).(2)Results of the 8-week resistance training intervention study in the second experiment: Before the 8-week intervention experiment: There was no difference between the two groups in the grip strength and the 1-minute sit-up performance group(p> 0.05);There was no difference in intestinal flora diversity index between groups(p> 0.05);there was no difference in depression level between the two groups(p>0.05).After the 8-week intervention experiment: in terms of strength and quality,the1-minute sit-up and grip strength scores of the two groups of subjects showed a very significant difference between the groups(p <0.01);In terms of intestinal flora,the intestinal flora α diversity of the two groups of subjects was significantly different from group to group(P <0.05);at the door level,the thick-walled bacteria in the intestine of the two groups of subjects The relative abundance of portal phylum and the relative abundance of Bacteroidetes were significantly different within and between groups(p <0.05);at the department level,the relative abundance of Lactobacillus in the intestine of the two groups of subjects was within and between groups The comparison showed a significant difference(p<0.05);at the genus level,the relative abundance of bacteria in the intestines of the two groups of subjects was not significantly different between the groups and between the groups(p> 0.05);between the species differences,the two groups received There was a very significant difference between the groups of 5 fungi(increased)such as Bifidobacteriaceae in the intestinal tract(p <0.01),and there was a significant difference between the three groups of fungi(decreased)including red ring fungi(p<0.05);In terms of depression,the depression levels of the two groups of subjects showed a very significant difference between the groups and between groups(p <0.01).Conclusions:(1)There is a significant negative correlation between the strength quality in sports ability and the risk of depression.(2)Resistance training can effectively improve the strength of depressed female college students,and then promote the improvement of their physical functions.(3)Resistance training can increase the number of beneficial flora components and decrease the components of depression-related flora,and then resistance training can effectively regulate the structure of intestinal flora,or it may be that 8-week resistance training reduces depression levels Key factor.(4)Resistance training can adjust the proportion of intestinal flora of depressed people to the proportion of intestinal flora of healthy people to achieve the purpose of improving depression.(5)Resistance training can significantly improve the depression status of female college students,and can be used as an effective intervention method to improve the depression of female college students. |
