Abstract/OtherAbstract:
|
The effects of menstrual cycle phase on the blood lactate response to exercise were examined in eumenorrheic women (n = 9). Exercise tests were performed at the mid-follicular and mid-luteal points in the menstrual cycle (confirmed by basal body temperature records and hormone levels). Blood lactates were measured at rest and during the recovery from exercise. Resting lactates were not different between the exercise tests; however, recovery lactates were significantly (p < 0.05) lower in the luteal compared to the follicular phase. The mechanism for these differences is unclear, but may be related to an estrogen mediated increased lipid metabolism inducing a concurrent reduction in carbohydrate metabolism. The present findings question the use of blood lactate monitoring as a suitable technique to measure exercise intensity in eumenorrheic women. |
