CARBOHYDRATE SUPPLEMENTATION AND MENSTRUAL PHASE DO NOT AFFECT PROLONGED PERFORMANCE
Speers, V. R., McLellan, T. M., Grisso, C. A., Smith, I. F., & Rodgers, C. D. (2001). Carbohydrate ingestion is not affected by menstrual phase in moderately trained females. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 1599.
Female triathletes (n = 6) completed four cycle-ergometer trials, at two different phases of the menstrual cycle with and without carbohydrate supplementation.
There was no differential effect of menstrual phase on performance nor was there any effect on performance from the CHO supplementation.
Implication. Women respond to prolonged exercise similarly in different phases of the menstrual cycle. Women do not respond with any performance improvement when supplemented with CHO.
