Effects of menstrual cycle on appetite-regulating hormones and energy intake in response to cycling exercise in physically active women

To our knowledge, this is the first study to compare how different phases of the menstrual cycle influence appetite-regulating hormones after acute exercise in healthy women. There were no differences in appetite-regulating hormones between the early follicular and mid luteal phases, whereas ovarian hormones were remarkably increased by cycling exercise in the mid luteal phase. These results highlight that appetite-regulating hormones in response to exercise do not appear to be influenced by the menstrual cycle.
