Fluid Retention over the Menstrual Cycle: 1-Year Data from the Prospective Ovulation Cohort
Figure 2
Patterns of fluid retention during the menstrual cycle for runners () and normally active women () relative to (a) the onset of menstrual flow, where 0 is the first day of flow, and (b) in ovulatory cycles only; the first day of elevated basal temperature is shown (denoted QBT rise) estimated by the validated quantitative basal temperature algorithm (QBT). To correct for differences in the duration of data collection by women, data are the average (bars ± standard error of the mean) of within-woman averages. Data were collected by 62 initially ovulatory women over one year. Fluid retention/“bloating” was scored from 0–4 using the Daily Menstrual Cycle diary.
