Study On The Effect Of Physical Activity Combined With Diet Intervention On Weight Loss Of Adult Obesity Patients

Objective: Objective: To explore the weight loss effects of three forms of exercise,namely moderate intensity aerobic,high intensity aerobic intermittent,and resistance,combined with comprehensive dietary intervention methods on adult obesity patients,and to compare the weight loss effects of different exercise methods.This provides a theoretical basis for future exploration of the weight loss effects of different exercise methods combined with dietary intervention on adult obesity patients,and provides a reference for formulating a scientific and effective exercise prescription.Methods: The methods of literature review,mathematical statistics and experiment were used in this paper.The experimental method mainly involves recruiting 80 subjects in Beijing based on the purpose of the experimental research,and randomly dividing them into a dietary intervention control group and three exercise+dietary comprehensive intervention experimental groups(moderate intensity aerobic exercise group,high intensity aerobic intermittent exercise group,and resistance exercise group),with 20 people in each group(10 men and 10 women each).The control group received a 12 week dietary intervention,while the experimental group received a 12 week exercise+dietary comprehensive intervention,Before and after the intervention,all subjects were tested for their body shape indicators,body composition indicators,and exercise tests were conducted.Then,SPSS26.0 was used for mathematical statistics analysis,mainly using repeated measurement ANOVA,paired sample T test,one-way ANOVA,etc to analyze the changes of each group of indicators before and after the intervention,and to test the impact of different exercise patterns on the weight loss effect of adult obesity patients and conduct a comparative study.Result:(1)Body shape indicators: After 12 weeks of intervention,the body weight,BMI,waist circumference,hip circumference,and waist to hip ratio of the three experimental groups showed a significant downward trend compared to before intervention(p<0.05).There was a statistically significant difference between the three experimental groups and the control group(p<0.05),but there was no significant difference between the three experimental groups.(2)Body composition indicators:After 12 weeks of intervention,except for fat and body weight,the body composition indicators of the three experimental groups showed a decreasing trend compared to before intervention(p<0.05).There was a statistically significant difference(p<0.05)between the three experimental groups and the control group,but there was no significant difference between the three experimental groups.(3)Correlation between BMI,waist circumference,and body fat rate: During the 12 week intervention weight loss process,the changes in BMI,waist circumference,and body fat rate showed an overall correlation in all three experimental groups(p<0.05),while there was no correlation in Group C(p>0.05).Conclusion:(1)Physical activity intervention;Dietary intervention;Obesity patients;The three comprehensive intervention methods for weight loss can significantly improve the body shape and body composition of adult obesity patients.There is no significant difference in weight loss effects among the three methods,but compared to high intensity aerobic intermittent exercise,the time spent is shorter.(2)BMI,waist circumference,and body fat rate only have an overall correlation and do not have a pairwise correlation.Therefore,when measuring weight loss effectiveness,multiple indicators should be comprehensively considered.
