The Effects Of Two Sports On Energy Intake And Appetite Of Normal And Overweight College Boys

PurposeExercise-induced compensatory responses affect exercise weight loss.Exercise may increase appetite and lead to increased energy intake,but whether there are differences in exercise patterns and populations remains to be studied.This study selected aerobic exercise and aerobic combined resistance exercise for a 6-week exercise intervention for normal weight and overweight college boys to explore whether exercise affects appetite and dietary energy intake.And does the change in appetite and energy intake caused by exercise differ depending on the size or mode of exercise of the athlete?MethodIn this study,47 male students of Zhongshan Vocational and Technical College were studied,including 30 normal weight students and 17 overweight students.Divided into the following six groups according to body weight category: the normal weight quiet control group,the normal weight aerobic exercise group,the normal weight aerobic combined resistance exercise group;the overweight quiet control group,the overweight aerobic exercise group and the overweight aerobic combined resistance exercise group.The exercise group underwent 6 weeks of exercise intervention,4 times a week,60 minutes each time.The aerobics group’s sports are jogging,aerobics and badminton,and the intensity is controlled at 60% to 75% of the maximum heart rate.The aerobic combined resistance exercise group performed 30 minutes aerobic exercise at first(same as the aerobic exercise group),and then completed the 30 minutes’ resistance exercise,and the resistance exercise was performed in 2 combinations each,with 8 combinations in each combination.Subject weight,resting metabolism,blood lipids(total cholesterol,triglycerides,high-density lipoprotein,low-density lipoprotein,free fatty acids),blood sugar,energy intake,appetite,and appetite hormone were assessed or measured before and after exercise intervention.Result1.Regardless of body weight category or exercise pattern,the overall effect analysis of the exercise: compared with before intervention,including the exercise group weight,the blood lipids,the blood sugar and the appetite hormone tyrosin peptide were decreased significantly(P <0.05),while the appetite and the energyintake were increased significantly(P <0.05).There was no significant change in the control group.2.According to the weight category,the combined exercise mode: after exercise intervention,the weight,blood lipids and appetite hormone tyrosin of overweight people decreased significantly(P <0.05),while the appetite and energy intake increased significantly(P <0.05);For the normal weight bodies’ weight(P <0.01),blood lipids and blood glucose were decreased significantly(P <0.05),and there was no significant change in the levels of energy intake,appetite and appetite hormone.3.Different exercise modes,combined with the type of body weight: the aerobic exercise group’s weight(P <0.01),blood lipids and the blood glucose decreased significantly(P <0.05);for the aerobic combined resistance exercise group’s weight(P<0.01)and the blood lipids were decreased significantly(P <0.05).There was no significant change in the two modes of exercise in terms of energy intake,appetite and appetite hormones.4.Different exercise modes,according to different bodies’ weight categories: no matter the aerobic exercise group or the aerobic combined resistance exercise group,the weight of normal’s weight was decreased significantly(P <0.05),and no significant change in overweight person,there were no significant changes in other indicators.5.After exercise intervention,the control group,the aerobic exercise group and the aerobic combined resistance exercise group only had differences between the resting metabolism and blood lipids(P <0.05),for other indicators,there were no significant difference.Conclusion1.For the overweight person,there was appeared a compensatory response with increased appetite and energy intake after 1.6 weeks of exercise intervention,but this phenomenon was not observed in normal weight’s person.2.No matter the aerobic exercise or aerobic joint resistance exercise,there is no different effects on appetite and energy intake.
