Effect of Aerobic Exercise on the Maximal Oxygen Uptake in Sedentary Healthy Adults:A Meta Analysis / 中国运动医学杂志

ABSTRACT

Objective Through this meta analysis of controlled clinical trials of the effect of aerobic exercise on the maximal oxygen uptake(VO2max) in sedentary healthy adults,we attempt to provide evidence for exercise prescription.Methods MEDLINE search for controlled trials that involved in the effect of aerobic exercise on the VO2max from 1976 to 2008 was conducted.The literatures were selected according to inclusion criteria and exclusion criteria.Review Manager 5.0 software provided a systematic evaluation for calculating VO2max Weighted Mean Difference with random effects model.Assessment of the sub-group of aerobic exercise intensity and literature publication bias were conducted.Results(1)Thirty five literatures were included in this review;involving 889 adults met the inclusion criteria.VO2max Weighted Mean Difference is 3.61ml/kg/min,95% confidence interval 2.96 ～ 4.25ml/kg/min,with an increase of 13.2%,comparing with the average VO2max values(27.26 ml/kg/min) before aerobic exercise.(2) The most effective exercise intensity was 70～80%VO2max,71～80% HRmax and 61～70% HRR according to the sub-group of aerobic exercise intensity meta analysis.Conclusion VO2max increased significantly due to participating in aerobic exercise in sedentary healthy adults.The results will provide a theoretical basis for the development of aerobic exercise prescription with appropriate intensity.
