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 .
Physical training improves insulin resistance syndrome markers in obese adolescents.
INTRODUCTION The purpose of this study was to test the hypothesis that physical training ( PT ) , especially high-intensity PT , would have a favorable effect on components of the insulin resistance syndrome ( IRS ) in obese adolescents . METHODS Obese 13- to 16-yr-olds ( N = 80 ) were r and omly assigned to one of the following 8-month interventions ; 1 ) lifestyle education (LSE)-alone every 2 wk , 2 ) LSE+moderate-intensity PT , and 3 ) LSE+high-intensity PT . PT was offered 5 d x wk(-1 ) . Plasma triacylglycerol ( TAG ) , total cholesterol ( TC ) , high-density lipoprotein cholesterol ( HDLC ) , very low-density lipoprotein cholesterol ( VLDLC ) , low-density lipoprotein cholesterol ( LDLC ) , low-density lipoprotein ( low density lipoprotein ( LDL ) ) particle size , apolipoproteins AI and B , glucose , insulin , and blood pressure were measured with st and ardized methods . RESULTS The intent-to-treat analyses for all subjects who completed pre- and post-tests regardless of their adherence to the interventions showed that the LSE+high-intensity PT group had more favorable changes than the LSE-alone group in TAG level ( P = 0.012 ) , TC/HDLC ( P = 0.013 ) , and diastolic blood pressure ( P = 0.031 ) . For efficacy analyses , all PT subjects who attended at least 2 d x wk(-1 ) ( 40 % ) were combined into one group ( LSE+PT ) and compared with the LSE-alone group . These two-group analyses showed significant interactions ( P < 0.001 ) between baseline values and group membership for deltaTAG , deltaVLDLC , and deltaTC/HDLC , such that subjects who had the least favorable baseline values showed the most beneficial impact of the PT . Of particular interest was a favorable effect of the PT on LDL particle size . CONCLUSION PT , especially high-intensity PT , had a favorable effect on several IRS markers in obese adolescents
