Abstract

The effects of the menstrual cycle on cardiorespiratory variables, blood lactate, and performance were studied in exercising females. Nine healthy subjects, 20--24 yr of age, were investigated in midfollicular and midluteal phases of the menstrual cycle at 33, 66, and 90% of maximum power output (light, heavy, and exhaustive exercise). Occurrence of ovulation was confirmed in all subjects by measurement of progesterone, which increased from 0.6 +/- 0.1 (mean +/- SE) in the follicular to 8.9 +/- 2.2 ng/ml in the luteal phase. There was no difference in heart rate (HR), ventilation, O2 uptake, or CO2 output between the two phases during light and heavy exercise, and there was no difference in HR at exhaustion. Cardiac output measured midway through light and heavy exercise periods was not affected by the phase of testing. Time for which exhaustive exercise could be maintained increased from 1.57 +/- 0.32 in the follicular to 2.97 +/- 0.63 min in the luteal phase (P less than 0.02). Blood lactate was higher in the follicular phase after heavy exercise (6.62 +/- 0.8 vs. 4.92 +/- 0.5 mmol/l) (P less than 0.05) and at exhaustion (8.12 +/- 0.9 vs. 6.76 +/- 0.6 mmol/L) (P less than 0.01). A further study showed no effect of cycle phase on lactate disappearance during exercise. We conclude that while aerobic performance and the cardiorespiratory adaptations to exercise are not influenced by the phase of the menstrual cycle, performance of high-intensity exercise is improved, and lactate production appears to be decreased in the luteal phase when estradiol and progesterone levels are elevated.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previously published works had limitations in procedures that weakened the implications of their findings: lack of dietary control prior to experiments and allowing hormonal concentrations to be manipulated only by endogenous fluctuation.

    “the previously published works had limitations in procedures that weakened the implications of the findings. Namely, the lack of dietary control prior to their experiments and allowing hormonal concentrations to be manipulated only by endogenous fluctuation (i.e., conducting experiments at different points in the menstrual cycle).”
  • Others have found results similar to the present study's findings.

    “Others have found similar results [4, 5, 14]; however, the previously published works had limitations in procedures that weakened the implications of the findings.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
