组合运动干预对肥胖女青少年身体成分、心血管风险因素及心肺适能影响的研究
Effects of Combined Motion Intervention on Body Composition,Cardiovascular Risk Factors and Cardiopulmonary Fitness of Obese Female Adolescents
摘要
Abstract
Background At present,there has been a dramatic increase in the number of obese children and adolescents globally,among which the prevalence of obesity in children aged 5 to 19 years has increased by about 8 times,and the prevalence of obesity in children aged 2 to 4 years has increased by about 1 times.Exercise intervention has an important effect on improving obesity and enhancing cardiorespiratory fitness.However,studies on the effects of combined motion intervention on obese female adolescents aged 14-16 years have not been addressed.Objective To investigate the effects of 12-week combined motion intervention on body composition,cardiovascular risk factors and cardiopulmonary fitness in obese female adolescents.Methods From May to July 2022,48 obese female adolescents aged 14 to 16 years old in Qufu City,Shandong Province were selected as research objects,numbered and divided into the experimental group(n=24)and control group(n=24)using random numbers.The experimental group finally included 20 female adolescents based on the inclusion and exclusion criteria,and the whole intervention lasted for 12 weeks,including rope skipping intervention and taekwondo intervention;while the control group did not perform any exercise intervention and other dietary or pharmacological interventions throughout the 12 weeks.The indicators such as height,body mass,body fat rate(BFR),waist circumference,BMI,blood pressure(BP),fasting plasma glucose(FPG),insulin,insulin resistance index(HOMA-IR)and maximal oxygen uptake(VO2max)were detected before and after the 12-week combined motion intervention and compared between the two groups,as well as before and after the intervention.Pearson correlation analysis was used to explore the correlation of BFR and waist circumference with VO2max in obese female adolescents.Results Before the intervention,there was no significant difference in age,height,body mass,BFR,waist circumference,BMI,systolic blood pressure(SBP),diastolic blood pressure(DBP),pulse pressure difference,FPG,insulin,HOMA-IR,maximal number of completions(Laps),maximal aerobic speed(MAS),and VO2max between the two groups(P>0.05).After 12-week combined motion intervention,BFR,waist circumference,SBP,DBP,FPG,insulin and HOMA-IR in the experimental group were lower than the control group,while Laps,MAS,VO2max was significantly higher than the control group(P<0.05).Compared with pre-intervention,the BFR,waist circumference,SBP,DBP,FPG,insulin and HOMA-IR were decreased and Laps,MAS,VO2max were increased after 12-week combined motion intervention(P<0.05).The results of correlation analysis showed that body fat percentage and circumference were negatively correlated with VO2max in obese female adolescents(r=-0.55,P<0.001;r=-0.41,P<0.001).Conclusion The 12-week combined motion intervention can improve body composition and cardiovascular risk factors in obese female adolescents,and also enhance cardiopulmonary fitness by increasing VO2max.关键词
