Abstract:
Objective:To understand the effects of different intensity of exercise combined with dietary intervention on body composition, lipid metabolism and gut microbiota in obese (nonalcoholic fatty liver disease,NAFLD) college students, so as to provide a theoretical reference for improving the health of the obese NAFLD female college students.
Methods:From March to Aprial 2022, 43 NAFLD female college students were recruited and randomly divided into HIIT group ( n =22) and MICT group( n =21). Subsequently, HIIT group received HIIT combined with diet intervention for 8 weeks and MICT group received MICT combined with diet intervention for 8 weeks, the changes of body composition, lipid metabolism and gut microbiota in NAFLD female college students were compared before and after intervention.
Results:Compared with that before the experiment, after 8 weeks of HIIT and MICT combined with dietary intervention, the weight, BMI, body fat mass, trunk fat mass, waist hip ratio and visceral fat area significantly decreased ( t = 15.56, 15.48, 15.74, 13.92, 6.51, 11.55; 13.64, 13.48, 15.82, 6.53, 4.40, 9.53), the levels of cholesterol and triglyceride and low density lipoprotein, bacillus coli and enterococcus significantly decreased ( t =6.75, 2.16, 6.86 , 3.06, 7.85; 3.55, 2.36, 4.00 , 3.32, 5.94); lactobacillus and bifidobacterium increased significantly ( t =6.64, 5.89; 5.11, 4.71); however, only HIIT group had a significant increase in the level of high density lipoprotein( t =5.08)( P <0.05). Compared with MICT group, body fat mass, trunk fat mass, visceral fat area and cholesterol level in HIIT group were significantly lower than those in MICT group ( t=2.20 , 2.10, 2.15, 2.26, P <0.05). There were no significant differences in other indicators between the two groups ( P >0.05).
Conclusion:The results show that HIIT and MICT have benefical effects on body composition, lipid metabolism and gut microbiota in obese NAFLD female college students , but HIIT is superior to MICT intervention in reducing body fat mass, visceral fat and improving lipid metabolism.
