Effect of resistive training on plasma lipid and lipoprotein levels in male adolescents

We studied fourteen 14 to 17-year old male adolescents before and after a9-week resistive exercise program and compared the changes in lipid and lipoprotein profiles with those in 14 non-exercising control subjects. Studies included determination of weight, body mass index (weight for height 2), percent body fat, blood pressure and resting heart rate, maximum heart rate and maximum oxygen consumption, and plasma lipids and lipoproteins. No significant differences were present between the two groups before training except that percent body fat was lower in the control subjects. After training, low-density lipoprotein cholesterol in the exercising subjects decreased from 120±15 to 95±13 mg/dL (P
