Effect of training on peak oxygen uptake and blood lipids in 13 to 14-year-old girls

The aim of this study was to investigate the effects of exercise training o n the peak oxygen uptake (peak (V) over dot O-2) and blood lipid profile of 13 to 14-y-old postmenarcheal girls. Treadmill determined peak (V) over do t O-2, total cholesterol, high density lipoprotein cholesterol, low density cholesterol, and triglycerides were the outcome measures assessed at basel ine and following exercise training. Twenty girls completed a 20-wk program me of exercise training which involved maintaining the heart rate at 75-85% maximum for 20 min, three times per week. Heart rate was rigorously monito red using telemetry throughout each training session. Eighteen girls acted as the control group. There were no significant (p > 0.05) changes in the o utcome measures following the training programme. Conclusions: These findings suggest that exercise training of this frequenc y, intensity and duration for a period of 20 wk has no significant effect o n either the peak (V) over dot O-2 or blood lipid and lipoprotein profile o f normolipidaemic, postmenarcheal girls.
