Abstract

Summary: Sleep interventions have rarely explored reductions in night‐to‐night fluctuations [i.e. intra‐individual variability (IIV)] in sleep, despite the negative impacts of such fluctuations on affective states and cognitive and physical symptoms. In a community‐based randomized controlled trial we evaluated whether physical exercise reduced IIV in self‐rated sleep outcomes among middle‐aged and older adults with sleep complaints. Under‐active adults 55 years and older (n = 66, 67% women) with mild to moderate sleep complaints were randomized to 12 months of a moderate‐intensity endurance exercise (n = 36) or a health education control group (n = 30). Daily sleep logs, Pittsburgh Sleep Quality Index (PSQI) and in‐home polysomnographic sleep recordings (PSG) were collected at baseline, 6 months and 12 months. Sleep log‐derived means and IIV were computed for sleep‐onset latency (SOL), time in bed, feeling rested in the morning, number of nighttime awakenings, and wake after final awakening (WAFA). Using intent‐to‐treat methods, at 6 months no differences in IIV were observed by group. At 12 months, SOL‐based IIV was reduced in the exercise group compared with the control (difference = 23.11, 95% CI: 3.04–47.18, P = 0.025, Cohen’s d = 0.57). This change occurred without mean‐level or IIV changes in sleep–wake schedules. For all sleep variables, except SOL and WAFA, IIV changes and mean‐level changes in each variable were negatively correlated (r = −0.312 to −0.691, P < 0.05). Sleep log‐derived IIV changes were modestly correlated with mean‐level PSQI and PSG‐based changes at 12 months. Twelve months of moderate‐intensity exercise reduced night‐to‐night fluctuations in self‐rated time to fall asleep, and this relationship was independent of mean‐level time to fall asleep.

  • Exercise training improves sleep quality and can promote lower variability in initial insomnia, independent of sleep time or sleep wake-up.

    “Based on this result, we can conclude that exercise training improves sleep quality and can also promote a lower variability in initial insomnia, independent of sleep time or sleep wake-up.”

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.
