The review was registered ( Number CRD42013004632 ) on PROSPERO , the International Prospect i ve Register of Systematic Review s. Results The results indicated that PA is associated with significant and beneficial changes in fat percentage , waist circumference , systolic blood pressure , insulin , low-density lipoprotein cholesterol , and total cholesterol , as well as with small non-significant changes in diastolic blood pressure , glucose , and high-density lipoprotein cholesterol .
Conclusion Although limited , results from controlled trials suggest that PA intervention may improve physical fitness and risk factors for cardiovascular disease in adolescents who are overweight or obese
Background The increasing prevalence of obesity in the pediatric age range has become a major concern .
Studies have investigated the role of physical activity ( PA ) to prevent obesity in this population .
However , previous review s did not focus on the effects of PA in overweight/obese adolescents on physical fitness and risk factors for cardiovascular disease altogether .
Objective The present systematic review analyzed trials investigating the effect of PA on aerobic capacity , muscle strength , body composition , hemodynamic variables , biochemical markers , and endothelial function in obese/overweight adolescents .
Effects of a school-based weight maintenance program for Mexican-American children: results at 2 years.
The prevalence of childhood overweight has increased significantly , with the highest rates noted among Mexican Americans . Many negative health outcomes are associated with overweight ; thus , there is a need for effective weight-loss interventions tailored to this group . This study evaluated 24-month outcomes of a r and omized , controlled trial involving an intensive lifestyle-based weight maintenance program targeting overweight Mexican-American children at a charter school in Houston , Texas . A total of 60 children ( 33 males , 55 % ) between the ages of 10 and 14 at or > 85th percentile for BMI were recruited . Participants were r and omized to an instructor-led intervention ( ILI ) or a self-help ( SH ) program , both aim ed at modifying eating and physical activity behaviors using behavior modification strategies . Changes in participants ' st and ardized BMI ( z BMI ) were assessed at baseline , 1 , and 2 years . Tricep skinfold , total cholesterol , triglycerides , high-density lipoprotein cholesterol , and calculated low-density lipoprotein were assessed at baseline and 1 year . ILI participants showed significantly greater decreases in z BMI at 1 and 2 years ( F = 26.8 , P < 0.001 , F = 4.1 , P < 0.05 , respectively ) compared to SH controls . ILI participants showed greater improvements in body composition , as measured by tricep skinfold ( F = 9.75 , P < 0.01 ) . Children in the ILI condition experienced benefits with respect to total cholesterol ( F = 7.19 , P < 0.05 ) and triglycerides ( F = 4.35 , P < 0.05 ) compared to children in the SH condition . Overall , the school-based intervention result ed in improved weight and clinical outcomes in overweight Mexican-American children , and z BMI was maintained over 2 years
