Exercise training improves sleep quality in middle-aged
and older adults with sleep problems: a systematic review
and older adults with sleep problems: a systematic review
The prevalence of insomnia in adults has been reported to range from 10% to 40% in Western countries and to exceed 25% in Taiwan. Epidemiological surveys have concluded that the prevalence of insomnia, which is characterised by persistent inability to fall asleep or maintain sleep, increases with age. Sleep problems have a significant negative impact on mental and physical health, impair quality of life, and increase healthcare costs. Lack of sleep can lead to increased fatigue and excessive daytime sleepiness. It can also impair the metabolic, endocrine, and immune systems, among other deleterious effects. However, fewer than 15% of patients with chronic insomnia receive treatment or consult a healthcare provider.
Exercise programs are also recommended to help prevent and treat sleep disorders as well as the depression associated with these disorders among the elderly. Having infrequent adverse effects and a low cost, participation in a community-based exercise program may be a favourable and easily accessible means of preventing and treating sleep problems among middle-aged and elderly populations. However, several meta-analyses examining the effect of exercise training on sleep yielded equivocal findings due to the small number of trials examined and the limited number of participants in those trials. Since those studies were published, new evidence from additional randomised trials has become available. Therefore, the research question for this systematic review was:
Does an aerobic or resistance exercise training program improve sleep quality in middle-aged and older adults with sleep problems?
