THE INFLUENCE OF SHORT-TERM AEROBIC TRAINING ON BLOOD-LIPIDS IN HEALTHY 10-12 YEAR-OLD CHILDREN

This study was designed to examine the ability of an endurance exercis e training program to alter blood levels of cholesterol, HDL-cholester ol, LDL-cholesterol, and triglycerides in children. Thirty-one sixth g rade students age 10-12 years (20 girls, 11 boys) who were healthy and active volunteered for participation. The training program consisted of 13 weeks of aerobic activities three days a week, 25 minutes per se ssion, with training intensity assessed by heart rate monitors. Serum lipids and maximal oxygen uptake (VO(2)max) were measured at the begin ning of a control period, 13 weeks later at the beginning of the train ing program, and at the termination of 13 weeks of training. VO(2)max values for the group improved 5.4%, but no significant changes were ob served in any of the blood lipid levels between the control and traini ng periods. These findings suggest that aerobic training of 13-weeks' duration is not an effective means of altering blood lipids in healthy normolipemic children.
