The programs based on aerobic exercise ( 60 min , 3 times/week , ≤75 % maximum heart rate ) improve the LDL-C and TG concentrations .
Moreover , the programs based on combined exercise ( ≥60 min , > 75 % maximum heart rate ) also improve the HDL-C concentration
OBJECTIVE The objective of this systematic review was to assess the effectiveness of different physical exercise interventions on the lipid profile ( high-density lipoprotein cholesterol ( HDL-C ) , low-density lipoprotein cholesterol ( LDL-C ) , total cholesterol ( TC ) , and triglycerides ( TG ) ) of obese children .
Effects of a 12-week exercise training programme on aerobic fitness, body composition, blood lipids and C-reactive protein in adolescents with obesity.
INTRODUCTION Developing effective exercise programmes for the paediatric population is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health and societal impact . In this study , the effects of a 12-week twice weekly additional exercise training , which comprised a combination of circuit-based resistance training and aerobic exercises , in additional to typical physical education sessions , on aerobic fitness , body composition and serum C-reactive protein ( CRP ) and lipids were analysed in 13- to 14-year-old obese boys contrasted with a control group . MATERIAL S AND METHODS Both the exercise group ( EG , n = 12 ) and control group ( CG , n = 12 ) participated in the typical 2 sessions of 40-minute physical education ( PE ) per week in schools , but only EG participated in additional 2 sessions per week of 45 to 60 minutes per session of exercise training , which comprised a combination of circuit-based resistance training and aerobic exercises maintained at 65 % to 85 % maximum heart rate ( HRmax = 220 - age ) . Body composition was measured using dual energy X-ray absorptiometry ( DEXA ) . Fasting serum CRP and blood lipids were analysed pre- and postexercise programme . Aerobic fitness was measured by an objective laboratory submaximal exercise test , PWC170 ( Predicted Work Capacity at HR 170 bpm ) . RESULTS Exercise training significantly improved lean muscle mass , body mass index , fitness , resting HR , systolic blood pressure and triglycerides in EG . Serum CRP concentrations were elevated at baseline in both groups , but training did not result in a change in CRP levels . In the CG , body weight increased significantly at the end of the 12-week period . CONCLUSION This study supports the value of an additional exercise training programme , beyond the typical twice weekly physical education classes , to produce physiological benefits in the management of obesity in adolescents , including prevention of weight gain
