| Outline of Final Research Achievements |
In endurance athletes, it is reported that it is likely to cause orthostatic tolerance due to post exercise hypotension (PEH). Exercise-associated amenorrhea and oligomenorrhea are in a state of estrogen deficiency compared with eumenorrhea. Estrogen mediated variability in peripheral vasodilation throughout the menstrual cycle may have an impact upon the temporal pattern and magnitude of PEH. The purpose of study was that we investigated the temporal pattern of cardiovascular recovery from an acute bout of exercise in female endurance athletes, in two groups of eumenorrhea and non-eumenorrhea. PEH was observed after exercise in both of eumenorrheic and non-eumenorrheic athletes. However, the degree of PEH was greater in non-eumenorrheic athletes than eumenorrheic athletes.
