Register for Exercise during later part of menstrual cycle may mean greater fat loss

2002 AUG 8 - (NewsRx.com & NewsRx.net) -- University of Adelaide PhD student Leanne Redman, who is studying the little-known impact of the menstrual cycle on women's exercise, has produced early results that show that exercising at the later menstrual phase could burn more fat and help women to feel less tired.
"Results suggest that exercise performance is improved during the later part of the menstrual cycle - that is, when circulating concentrations of ovarian hormones (estrogen and progesterone) are high," she said.
At the later menstrual phase, the hormones promote the use of fats as an energy source to support exercise. The use of fat in aerobic activity provides a more efficient delivery of energy, and results in fewer waste products being produced. These waste products normally contribute to fatigue.
Redman's findings are of international interest to sport scientists and physicians involved in prescribing exercise programs to women for sport, fitness or health.
"According to our research, there would be clear benefits to women if their weight management programs, as well as providing a sound diet and lifestyle, took into account the physiological changes that occur during the menstrual cycle," she said.
This phase will look at the impact of synthetic hormones in the oral contraceptive pill on women's metabolism and exercise capacity. This article was prepared by Women's Health Weekly editors from staff and other reports.
