In conclusion , overweight and obese youth can improve physical fitness across a variety of test measures .
When fitness improves , beneficial health effects are observed in some , but not all chronic disease risk factors
A systematic review of literature was conducted to examine the association between changes in health-related fitness ( e.g. aerobic capacity and muscular strength /endurance ) and chronic disease risk factors in overweight and /or obese youth .
Effects of exercise training on vascular function in obese children.
OBJECTIVES Atherosclerosis is a disease that begins in childhood ; endothelial dysfunction is its earliest detectable manifestation , and primary prevention strategies are likely to be most effective if instituted early . The aim of this study was to characterize the impact of obesity on vascular function in young children and to determine whether an exercise program improves abnormalities in vascular function . STUDY DESIGN The influence of 8 weeks of exercise training was examined in 14 obese subjects , 8.9 + /- 0.4 years of age , with the use of a r and omized crossover protocol . Conduit vessel endothelial function was assessed by means of high-resolution ultrasound and flow-mediated dilation of the brachial artery ( FMD ) . RESULTS Exercise training did not change subcutaneous fat mass , body weight , or body mass index . FMD in the obese group was significantly impaired relative to matched control subjects at entry ( 6.00 % + /- 0.69 % to 12.32 % + /- 3.14 % , P < .0001 ) . FMD significantly improved with exercise training ( 7.35 % + /- 0.99 % , P < .05 ) in the obese group . CONCLUSIONS Conduit vessel FMD , a vali date d surrogate measure of early atherosclerosis , was impaired in obese children but improved as a result of exercise training . This study supports the value of an exercise program in the treatment of obese children in a primary prevention setting
