The Effect Of Resistance Training Combined With Aerobic Exercise On Fat Loss In General Male College Students

Objective:An intervention experiment was conducted with the average male college student to compare the differences in body composition and body shape between using resistance training combined with aerobic exercise and aerobic exercise alone over a certain time period,and to explore the effects on fat loss outcomes.This study is based on the principle of consistent oxygen consumption in order to help optimize fitness programs and provide theoretical guidance for future fat loss populations with different needs.Methods: This study used the literature method,expert interview method,mathematical and statistical method,and experimental method.A 5-week exercise intervention(the first week was the preparation week)was conducted on 32 general male college students,in which group A performed resistance training combined with aerobic exercise and group B performed continuous aerobic exercise alone,using the principle of consistent oxygen consumption,and6 body morphology indexes(9 data in total)and 12 body composition indexes(14 data in total)were measured before and after the intervention for the experimental subjects.The data of body morphology and body composition indexes before and after the intervention in each group were compiled,analyzed and discussed in a time cycle to draw relevant conclusions and recommendations.Results:(1)In terms of body morphology,a total of 9 data from 6 body morphology indexes showed that there were different degrees of growth trends in chest circumference,hip circumference,left and right thigh circumference,left and right thigh circumference and left calf circumference indexes in group A after the experiment,and there was a decreasing trend in waist circumference,with very significant differences before and after the experiment(P<0.01);there was also an increasing trend in right calf circumference,with significant differences before and after the experiment(P<0.05).in group B,there were significant differences in chest circumference,There were different degrees of decrease in chest circumference,waist circumference,hip circumference,left and right thigh circumference and left and right thigh circumference after the experiment in group B.The difference was very significant(P<0.01);there was no significant difference(P>0.05)between left and right calf circumference before and after the experiment.(2)In terms of body composition,a total of 14 data of 12 body composition indexes showed that: after the experiment in group A,skeletal muscle mass,defatted body weight and whole-body water content tended to increase to different degrees,body fat rate,subcutaneous fat rate,whole-body fat mass,upper and lower limb fat mass and trunk fat mass tended to decrease to different degrees,and body weight first increased and then decreased,and the difference between before and after the experiment was very significant(P<0.01);BMI first increased and then decreased,and the difference between before and after the experiment was very significant(P<0.01).BMI,body weight,skeletal muscle mass,defatted body weight,whole body water content,body fat rate,visceral fat rate,subcutaneous fat rate,whole body fat mass,upper and lower limb fat mass and trunk fat mass all tended to decrease to a greater extent after the experiment in group B compared with group A.The difference between the two groups was very significant(P<0.05).The differences were highly significant(P<0.01).Conclusions:(1)Resistance training combined with aerobic exercise can effectively help the average male college student lose fat,especially in terms of fat loss weight gain,maintenance of total body water content and reduction of body fat percentage.(2)Aerobic exercise alone can rapidly reduce body composition index within 2-3 weeks,which is more conducive to rapid weight loss in a short period of time,but it will be accompanied by loss of skeletal muscle content,defatted body weight,whole-body water content and body circumference.(3)Compared to the immediate weight loss effect of aerobic exercise alone,resistance training combined with aerobic exercise requires 2 weeks or more before the effect becomes obvious;while the effect of aerobic exercise alone begins to show a gradual weakening trend after the 3rd and 4th weeks.(4)In terms of maintaining whole body water content,resistance training combined with aerobic exercise showed only a minimal decrease over 4 weeks,while aerobic exercise alone decreased more rapidly in the first 2 weeks than in the last 2 weeks.(5)In terms of visceral fat reduction,aerobic exercise alone was superior to resistance training combined with aerobic exercise across the board.Therefore,for people with a large weight base who need to reduce their body weight or visceral fat rate(e.g.,NAFLD)rapidly for a short period of time,simple continuous aerobic exercise is more suitable for them.
