Abstract

The aim of the study was to help clarify the equivocal findings with slow wave sleep (SWS) stages 3 and 4, following running in physically trained individuals. Six females (22-24 years) ran at 75% of their VO2max for 2 X 40 min periods on two separate occasions, 14.30-17.30 h: once under hot conditions, causing a rectal temperature (Tr) increase averaging 2.3 degrees C, and once with additional cooling, reducing the Tr rise to an average of 1.0 degree C. Compared with baseline nights, no significant sleep effects were found on the cool run. However, after the hot run, SWS, particularly stage 4 sleep, showed significant increases, and REM sleep was decreased. It was concluded that body heating effects during running may play a key role in SWS changes, and that additional cooling seems to eliminate any potential SWS increase.

  • Several mechanisms provide a rationale for the improvement in insomnia symptoms from exercise, including reducing core body temperature for sleep onset, increasing melatonin and serotonin secretion, reducing depression and anxiety, and improving autonomic regulation which may reduce hyperarousal associated with insomnia.

    “Several mechanisms that provide a rationale for the improvement in insomnia symptoms from exercise have been suggested [133,136,137,138,139]; these include but are not limited to reducing core body temperature for sleep onset [140,141,142,143], increasing melatonin and serotonin secretion [131,144], reducing depression and anxiety, and improving autonomic regulation which may reduce hyperarousal”

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.
