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 .
Reliability of the PEDro scale for rating quality of randomized controlled trials.
BACKGROUND AND PURPOSE Assessment of the quality of r and omized controlled trials ( RCTs ) is common practice in systematic review s. However , the reliability of data obtained with most quality assessment scales has not been established . This report describes 2 studies design ed to investigate the reliability of data obtained with the Physiotherapy Evidence Data base ( PEDro ) scale developed to rate the quality of RCTs evaluating physical therapist interventions . METHOD In the first study , 11 raters independently rated 25 RCTs r and omly selected from the PEDro data base . In the second study , 2 raters rated 120 RCTs r and omly selected from the PEDro data base , and disagreements were resolved by a third rater ; this generated a set of individual rater and consensus ratings . The process was repeated by independent raters to create a second set of individual and consensus ratings . Reliability of ratings of PEDro scale items was calculated using multirater kappas , and reliability of the total ( summed ) score was calculated using intraclass correlation coefficients ( ICC [ 1,1 ] ) . RESULTS The kappa value for each of the 11 items ranged from.36 to.80 for individual assessors and from.50 to.79 for consensus ratings generated by groups of 2 or 3 raters . The ICC for the total score was.56 ( 95 % confidence interval=.47-.65 ) for ratings by individuals , and the ICC for consensus ratings was.68 ( 95 % confidence interval=.57-.76 ) . DISCUSSION AND CONCLUSION The reliability of ratings of PEDro scale items varied from " fair " to " substantial , " and the reliability of the total PEDro score was " fair " to " good .
