| Obesity seriously affects children's physical health,the study of obese children and teenagers' seven weeks of aerobic exercise and diet control intervention,observe its body shape,body function and body physiological and biochemical indicators of change,to based on predecessors' research,contrast aerobic exercise and diet control intervention effects on the obese children and teenagers' physical health,for the obesity children and teenagers' control,improve life quality,improve physical health to provide scientific and effective intervention methods.The research methods46 obese children and teenagers who participated in the 2017 Shanghai peak weight loss summer camp were studied,including 19 children(11 boys and 8 girls)and 27 teenagers(11 boys and 16 girls).Before entering the camp,the subjects and their parents signed the informed consent for the weight loss experiment.Before the experiment,the subjects underwent a comprehensive physical examination.Measuring body shape: height(cm)and weight(kg),chest circumference(cm),WC(cm),HC(cm),thigh circumference(cm),WHR,skin fold(mm),BMI,BFP,body function: SBP(mmHg),DBP(mmHg),lung capacity,HR(times/min),physiological and biochemical,FBG(mmoL/L),TG(mmoL/L),TC(mmoL/L),FINS(PmoL/L),and other indicators of measuring,finishing in contrast the data before the experiment.A total of 46 children and teenagers were subjected to a seven-week closed aerobic exercise combined with dietary management.The aerobic exercise intervention process was dominated by medium and small intensity,and the items included fast walking,running,aerobic aerobics,cycling physical training,swimming,basketball,badminton and table tennis.Three meals a day are made according to the basic metabolism required by individuals,calorie intake is strictly controlled,and weight changes are recorded daily.Seven weeks later,the subjects underwent a comprehensive physical examination,and the comparison data after the intervention were collated.IBM SPSS22.0 was used to conduct statistical analysis on the data of 46 children and adolescents before and after the intervention,and to compare the changes of body shape,body function and physiological and biochemical indexes of aerobic exercise and diet intervention at different ages.If p<0.01,the difference was statistically significant.The results of the study(1)changes of children's body shape indicators before and after interventionChildren: there was no significant difference in height(P > 0.05),but there was significant difference in body weight,waist circumference and BMI(P < 0.01).The body weight decreased by 6.983 kg,waist circumference decreased by 11.103 cm,and BMI decreased by 3.369.There were significant differences in chest circumference,hip circumference,upper arm skin fold thickness,subscapular skin fold thickness,waist-hip ratio and body fat percentage between boys and girls,with significant differences in boys(P < 0.01).The girl had a significant difference(P < 0.05),with a decrease of 8.038 cm in chest circumference,7.66 cm in hip circumference,5.77 cm in thigh circumference,8.453 mm in upper arm fold thickness,11.51 mm in subscapular fold thickness,0.048 in waist-hip ratio,and 4.135 in body fat percentage.Boys' thigh circumference(significant P < 0.05),girls' thigh circumference(P > 0.05)Adolescents: after intervention,height was not significant(P > 0.05),but chest circumference,waist circumference(WC),hip circumference(HC),thigh circumference,upper arm skin fold thickness,subscapular skin fold thickness,BMI,WHR and BFP were significant(P < 0.01),except for female adolescents with significant waist circumference(P < 0.05).The mean height increased by 0.036 cm,weight decreased by 12.623 kg,chest circumference decreased by 10.08 cm,waist circumference decreased by 12.73 cm,hip circumference decreased by 10.125 cm,thigh circumference decreased by 7.86 cm,skin fold thickness decreased by 12.4mm in the upper arm,skin fold thickness decreased by 18.135 mm in the subscapular,waist and hip ratio decreased by 0.07,BMI decreased by 6.638,body fat percentage decreased by 6.482.(2)changes of children and teenagers' physical function indicators before and after the interventionChildren: the quiet heart rate,systolic blood pressure,and diastolic blood pressure were significantly lower in boys(P < 0.01)and girls(P < 0.05).The quiet heart rate(HR)was reduced by 12.7675 beats /min,lung capacity was increased by 369.313 mL,systolic blood pressure(SBP)was decreased by 14.115 mmHg,and diastolic blood pressure(DBP)was decreased by 13.443 mmHg.Lung capacity was significant in boys(P < 0.05),but not in girls(P > 0.05).Teenager: male young quiet heart rate(HR)has a significant(P < 0.05),female young quiet heart rate(HR)has very significant(P < 0.01),a young male lung capacity has very significant(P < 0.01),female youth lung capacity has a significant(P < 0.05),systolic blood pressure(SBP)and diastolic blood pressure(DBP)has very significant(P < 0.01);Silent heart rate(HR)was decreased by 14.355 beats /min,lung capacity increased by 1386.575 mL,systolic blood pressure(SBP)decreased by 14.115 mmHg,and diastolic blood pressure(DBP)decreased by 10.915 mmHg.(3)changes of children's physical physiological and biochemical indexes before and after the interventionChildren: FBG,TG,TC,FINS were significantly significant in boys(P < 0.01),FBG,TC,FINS were significantly significant in girls(P < 0.01),TG,FINS were significantly significant in girls(P < 0.05).Fasting blood glucose(FBG)decreased by 0.43mmoL/L,triglycerides(TG)decreased by 0.088mmoL/L,total cholesterol(TC)decreased by 0.7635mmoL/L,and fasting insulin(FINS)decreased by 63.315pmoL/L.Teenager: male young fasting blood glucose(FBG),triglyceride(TG),total cholesterol(TC)and fasting insulin(FINS)has very significant(P < 0.01),female young fasting blood glucose(FBG)have significant(P < 0.05),triglyceride(TG)is not significant(P > 0.05),total cholesterol(TC)and fasting insulin(FINS)has very significant(P < 0.01);Fasting blood glucose(FBG)decreased by 0.559mmoL/L,triglycerides(TG)decreased by 0.2465mmoL/L,total cholesterol(TC)decreased by 1.1805mmoL/L,and fasting insulin(FINS)decreased by 85.8995pmoL/L.The research conclusion(1)After seven-week aerobic exercise combined with food control intervention,the body shape,body function and body physiological and biochemical indexes of obese children and adolescents have changed significantly,which proves that aerobic exercise combined with food control can effectively improve the physical health of obese children and adolescents,and can be used as weight loss,body shape improvement,body function improvement,physiological and biochemical regulation,and weight improvement for children and adolescents.Effective intervention methods for obese adolescents physical health.(2)Comparing the difference of body shape,body function and body physiological and biochemical indexes between obese children and adolescents before and after intervention,it is concluded that the overall effect of aerobic exercise combined with food control on obese adolescents physical health intervention is more obvious than that of obese children.It is possible that aerobic exercise combined with food control intervention is more suitable for obese adolescents,but for obese children,there may be more effective intervention methods,which need further study.(3)There is no significant difference in height between children and adolescents before and after intervention,but the difference of mean value shows that the change of height of children is slightly larger than that of adolescents,which may be influenced by growth and development factors.(4)There are still some shortcomings in this study.For example,in the process of aerobic exercise intervention,children and adolescents train in different classes.Even if the target heart rate is used as the standard to strictly control the exercise load,there are certain differences in training density and recovery time between classes,which may have some influence on the experimental results,but it does not affect the experimental results. |
