A Randomized Controlled Trial of the Effect of Exercise on Sleep

Singh, Nalin A., Clements, Karen M., Fiatarone, Maria A.·1997·Sleep

Abstract

We tested the hypothesis that exercise would improve subjective sleep quality and activity in depressed elders. A 10-week randomized controlled trial was utilized. Participants consisted of a volunteer sample, aged > 60 with a diagnosis of major or minor depression or dysthymia. A total of 32 subjects aged 60-84 years with a mean age of 71.3 +/- 1.2 years was used. Intervention consisted of a supervised weight-training program three times a week or an attention-control group. Main outcome measures were Pittsburgh Subjective Sleep Quality Index (PSQI), Likert Scale of Subjective Sleep Quality and Quantity. Paffenbarger Activity Index. Geriatric Depression Scale (GDS). Beck Depression Inventory (BDI), Hamilton Rating Scale of Depression (HRSD), and the Medical Outcomes Survey Short Form 36 (SF-36). Results showed that exercise significantly improved all subjective sleep-quality and depression measures. Depression measures were reduced by approximately twice that of controls. Habitual activity was not significantly increased by exercise. Quality of life subscales significantly improved. In a forward stepwise multiple regression, percent improvement in GDS and percent increase in strength remained significant predictors of the improvement in total PSQI score (r = 0.71, p = 0.0002). In conclusion, weight lifting exercise was effective in improving subjective sleep quality, depression, strength, and quality of life without significantly changing habitual activity.

  • 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”
  • Short-term experimental studies have shown a positive impact of exercise on subjective sleep quality among mildly to moderately sleep-impaired adults.

    “Short-term experimental studies have shown a positive impact of exercise on subjective sleep quality among mildly to moderately sleep-impaired adults (3–5).”

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.
