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 .
Does exercise intensity affect blood pressure and heart rate in obese adolescents? A 6-month multidisciplinary randomized intervention study.
BACKGROUND Aerobic exercise improves cardiovascular health in general , but whether the impact varies with exercise intensity is not clear . OBJECTIVE The aim of the current study was to compare the effects of a high-intensity aerobic exercise training ( HIT ) vs. a low-intensity aerobic exercise training ( LIT ) on blood pressure ( BP ) , heart rate ( HR ) and heart rate variability ( HRV ) in obese adolescents . METHODS Forty-three ( 13 - 18 years ) Tanner stage ( III-IV ) matched obese adolescents were studied in a r and omized trial of either HIT ( corresponding to the ventilatory threshold I ; n = 20 ) or LIT ( corresponding to 20 % below the ventilatory threshold I ; n = 23 ) programme for a period of 6 months . All participants also received a multidisciplinary therapy that included nutritional , psychological and clinical counselling . Both HIT and LIT sessions were isocaloric , with energy expenditure set at 350 kcal . BP , HR and HRV were measured along with markers of body adiposity and insulin resistance before and after the respective interventions . RESULTS The participants in both groups had similar physical and clinical characteristics . After the 6-month intervention , systolic , diastolic and mean BP decreased ( P < 0.05 , for all ) similarly in both groups , whereas waist circumference , HR and HRV showed beneficial changes only in the HIT group ( P < 0.05 ) . CONCLUSION Aerobic exercise training set at a high intensity compared with the low intensity appears to have additional benefits on abdominal obesity and cardiovascular health in that it enhances the parasympathetic and autonomic modulation of the heart in obese adolescents
