  1. Physical training, lifestyle education, and coronary risk factors in obese girls.

    Article - En anglais

    The effects of supervised physical training (PT) and lifestyle education (LSE) on risk factors for coronary artery disease and non-insulin-dependent diabetes mellitus were compared in obese 7-to 11-yr-old black girls.

    The subjects were divided into two groups.

    The PT group (N=12) completed a 5-d. wk-1,10-wk, aerobic training program ; and the LSE group participated in weekly lifestyle discussions to improve exercise and eating habits.

    The PT group showed a significant increase in aerobic fitness (P<0.05) and decrease in percent body fat (P<0.05), while the LSE group declined significantly more in dietary energy and percent of energy from fat (P<0.05).

    Fasting insulin did not change significantly.

    The LSE group declined significantly more than the PT group in glucose (P<0.05), and glycohemoglobin declined from baseline in both groups (P<0.05).

    Lipid changes were similar in the two groups : total cholesterol/high density lipoprotein cholesterol (P<0.01) and triglycerides (P<0.05) declined, the low density lipoprotein (LDL)/apoproteinB ratio increased (which indicates a decrease in small dense LDL) (P<0.05) and lipoprotein (a) increased (P<0.05).

    Thus, the interventions were similarly effective in improving some diabetogenic and atherogenic factors, perhaps through different pathways ; i.e., the PT improved fitness and fatness, while the LSE improved diet.

    Exercise and diet-induced changes in lipoprotein (a) require further investigation.
