Abstract
  • The purpose of this study was to determine the influence of changes in circulating estradiol levels on the insulin response to an acute bout of exercise, in college age women who were not using hormonal contraceptives. Ten eumenorrheic women completed exercise sessions (60 minutes, 65% of VO2max) in the mid-follicular (days 3 - 7; low estradiol levels) and mid-luteal (days 20 - 25; high estradiol levels) phases of their menstrual cycle. Blood samples were taken pre-exercise, immediately post-exercise, and 30 minutes into recovery. Results indicate that there is not a significant change in resting or exercise insulin levels during the low and high estradiol phases of the menstrual cycle (p = 0.415). In addition, the added stress of exercise does not cause a significantly different percentage change (i.e., level of decrease) in insulin between the low and high estradiol phases of the menstrual cycle (p = 0.494).
