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 .
Effect of Individualized Exercise Training Combined with Diet Restriction on Inflammatory Markers and IGF-1/IGFBP-3 in Obese Children
Aims : The present study was design ed to examine the possible changes in body composition , insulin-like growth factor 1 ( IGF-1 ) , insulin-like growth factor-binding protein-3 ( IGFBP-3 ) and inflammatory markers of obese children in response to a 2-month program of exercise training combined with dietary restriction . Methods : Twenty-eight obese children ( age 13.2 ± 0.7 years , body mass index 30.9 ± 1.3 ) were r and omly assigned to a diet/training group or a control group and were tested two times : once before and once at the end of the experimental period . They performed a progressive cycle ergometer test at each visit . Substrate oxidation was evaluated by indirect calorimetry . Training was individualized at the point when fat oxidation was maximal ( Lipoxmax ) . Results : Diet/training induced a significant decrease in body weight and body fat ( after vs. before , p < 0.01 ) . Plasma concentrations of IGF-1 , IGFBP-3 and inflammatory markers were significantly decreased after the completion of the program . The diet/training program result ed in an increase in VO2maxACSM ( 24.6 ± 2.5 to 33.1 ± 3.1 ml/min/kg , p < 0.001 ) at the end of the intervention period . Conclu- sion : These data suggest that in the presence of weight loss , exercise training improves inflammatory markers and IGF-1 and IGFBP-3 levels in obese children
