摘　　要：AIM:To determine the benefits of a 10-wk resistance training programme on cardiovascular health in nonobese and active adolescents.METHODS:This is a pragmatic randomised controlled intervention.The study was carried out in a Hong Kong Government secondary school.Thirty-eight lean and active boys and girls were randomised to either the resistance training group or the control group.Students in the resistance training group received in-school 10-wk supervised resistance training twice per week,with each session lasting 70 min.Main outcome measures taken before and after training included brachial endothelial dependent flow-mediated dilation,body composition,fasting serum lipids,fasting glucose and insulin,high sensitive C-reactive protein,24-h ambulatory blood pressure and aerobic fitness.RESULTS:The only training related change was in endothelial dependent flow-mediated dilation which increased from 8.5%to 9.8%.A main effect of time and an interaction(P<0.005) indicated that this improvement was a result of the 10-wk resistance training.Main effects for time(P<0.05) in a number of anthropometric,metabolic and vascular variables were noted;however,there were no significant interactions indicating the change was more likely an outcome of normal growth and development as opposed to a training effect.CONCLUSION:Ten weeks of resistance training in school appears to have some vascular benefit in active,lean children.AIM:To determine the benefits of a 10-wk resistance training programme on cardiovascular health in nonobese and active adolescents.METHODS:This is a pragmatic randomised controlled intervention.The study was carried out in a Hong Kong Government secondary school.Thirty-eight lean and active boys and girls were randomised to either the resistance training group or the control group.Students in the resistance training group received in-school 10-wk supervised resistance training twice per week,with each session lasting 70 min.Main outcome measures taken before and after training included brachial endothelial dependent flow-mediated dilation,body composition,fasting serum lipids,fasting glucose and insulin,high sensitive C-reactive protein,24-h ambulatory blood pressure and aerobic fitness.RESULTS:The only training related change was in endothelial dependent flow-mediated dilation which increased from 8.5%to 9.8%.A main effect of time and an interaction(P<0.005) indicated that this improvement was a result of the 10-wk resistance training.Main effects for time(P<0.05) in a number of anthropometric,metabolic and vascular variables were noted;however,there were no significant interactions indicating the change was more likely an outcome of normal growth and development as opposed to a training effect.CONCLUSION:Ten weeks of resistance training in school appears to have some vascular benefit in active,lean children.
