Effect Of Three Months Of Exercise On Obese Adults' Maximum Oxygen Uptake And Anaerobic Threshold

Objective:To investigate the effect of the VO₂max and anaerobic threshold in obese people of 3 months exercise intervention.Methods:the subjects were divided into control group and experimental group,the control group was 34 healthy people?14 women and 20 men?,the experimental group was 30 obesity people?14 women and 16 men?,by using weight tester and the German CORTEX Metamax 3B portable gas metabolism,the experimental group and the control group were tested index of weight?kg??BMI?kg/m²??VO₂max?ml/kg/min??HR_max?Sub/min??VE_max?L/min??AT-HR?Sub/min??ATVO₂?%??ATVE?L/min??AT-load?W??AT-VO₂max?ml/kg/min?and AT-ME before and after the intervention.The test dates were recorded in Microsoft Excel 2007 and the dates of the measured indicators were collated and analyzed by using SPSS 19.0.Results:?1?Before the intervention,the weight and BMI of the experimental group were extremely and significantly higher than those of the control group?P<0.01?.The HR_maxax of the experimental group was extremely and significantly lower than the control group?P<0.01?.?2?Among the difference In the experimental group compared with control group the difference,the indicators of AT-VO₂max,VEmax and the AT-load of the difference between before the intervention in the experimental group and control group were significantly higher than the difference before the intervention in the experimental group and control group?p<0.05?;The weight index of the difference between before the intervention in the experimental group and control group was significantly lower than the difference before the intervention in the experimental group and control group?p<0.05?.?3?After the fitness intervention,the indicators of VE_max?AT-load and AT-VO₂max in the after-intervention experimental male group were significantly higher than those in the per-intervention male group?p<0.05?.The index of the weigh of the experimental female group after intervention was significantly lower than before?p<0.05?,The index of AT-load of the experimental female group after intervention was significantly higher than before?p<0.05?.?4?In the difference comparison before and after the intervention of experimental group,the index of weigh of difference of experimental female group between before and after the intervention was significantly less than experimental male group?p< 0.05?,the index of VE_maxax and AT-load of difference of experimental male group between before and after the intervention was significantly higher than experimental female group?p<0.05?.Conclusion:?1?In the study of"the aerobic+resistance+stretching"fitness programs could reduce the difference of the aerobic capacity and VE_maxax between obese and normal weight group,the aerobic capacity of obese people had a significant boost.?2?Three months of fitness intervention could significantly enhance the aerobic capacity of obese men,and improve aerobic capacity of obese men significantly,and it could significantly reduce the weight of obese women.?3?In this study,the aerobic threshold and VE_maxax of obese men were significantly better than those of obese women.
