Abstract
Insomnia symptoms (e.g., difficulty initiating or maintaining sleep) are common in cardiac patients and contribute to impaired mood, concentration, and motivation. The purpose of this study was to assess whether insomnia symptoms relate to unpleasant affect during exercise and poor exercise adherence. The Insomnia Severity Index was administered to 349 patients in 12 week exercise-based cardiac rehabilitation. Affect was measured in 57 patients with the Physical Activity Affect Scale, 5 minutes before and 15 minutes after onset of moderate intensity exercise. Exercise adherence (attendance, ∆ functional capacity, weekly exercise duration, dropout) was ascertained by chart review. Greater insomnia severity was associated with shorter weekly exercise duration but not with other adherence measures. Affective improvement during exercise was associated with greater insomnia severity, but not with adherence. Insomnia symptoms do not appear to interfere with objectively measured exercise adherence, and exercise might support affect regulation in cardiac patients with insomnia.
