Decreased thermal conductance during the luteal phase of the menstrual cycle in women

Frascarolo, P., Schutz, Y., Jequier, E.·1990·Journal of Applied Physiology

Abstract

To study the influence of the menstrual cycle on whole body thermal balance and on thermoregulatory mechanisms, metabolic heat production (M) was measured by indirect calorimetry and total heat losses (H) were measured by direct calorimetry in nine women during the follicular (F) and the luteal (L) phases of the menstrual cycle. The subjects were studied while exposed for 90 min to neutral environmental conditions (ambient temperature 28 degrees C, relative humidity 40%) in a direct calorimeter. The values of M and H were not modified by the phase of the menstrual cycle. Furthermore, in both phases the subjects were in thermal equilibrium because M was similar to H (69.7 +/- 1.8 and 72.1 +/- 1.8 W in F and 70.4 +/- 1.9 and 71.4 +/- 1.7 W in L phases, respectively). Tympanic temperature (Tty) was 0.24 +/- 0.07 degrees C higher in the L than in the F phase (P less than 0.05), whereas mean skin temperature (Tsk) was unchanged. Calculated skin thermal conductance (Ksk) was lower in the L (17.9 +/- 0.6 W.m-2.degrees C-1) than in the F phase (20.1 +/- 1.1 W.m-2.degrees C-1; P less than 0.05). Calculated skin blood flow (Fsk) was also lower in the L (0.101 +/- 0.008 l.min-1.m-2) than in the F phase (0.131 +/- 0.015 l.min-1.m-2; P less than 0.05). Differences in Tty, Ksk, and Fsk were not correlated with changes in plasma progesterone concentration. It is concluded that, during the L phase, a decreased thermal conductance in women exposed to a neutral environment allows the maintenance of a higher internal temperature.

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?

  • During the luteal phase compared with the follicular phase, the threshold for sweating and vasodilation is increased and thermal conductance and skin blood flow are decreased.

    “Increased threshold for sweating [39, 40] and for vasodilation [39–41] as well as decreased thermal conductance and skin blood flow [42] is observed during the LP compared to the FP.”
  • The majority but not all studies find an increase in energy expenditure or basal metabolic rate of about 5% to 9% in the luteal phase.

    “The majority [29,108–113] but not all [114,115] studies find an increase in energy expenditure or basal metabolic rate of about 5% to 9% in the luteal phase.”
  • A rise in body temperature of 0.3-0.7°C would induce a small increase in metabolic heat production that may be within the range of measurement error.

    “however, a rise in body temperature of 0.3–0.7°C would induce a small increase in metabolic heat production that may be within the range of measurement error [110].”

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.
