Different Exercising Intensities and Frequencies of Exercise on Depressive Mood and Insomnia

17 de enero de 2022 actualizado por: The University of Hong Kong

Effects of Different Exercising Intensities and Frequencies of Walking Exercise on Depressive Mood and Insomnia in Older Adults

Aerobic exercise intervention for depression was conventionally recommended three times weekly with moderate intensity in previous studies, but little is known about the training effect of aerobic exercise at low frequency and vigorous intensity. The purpose of this study is to compare the training effect of aerobic exercise at different exercising frequencies and intensities on older adults with comorbid insomnia and depressive symptoms. In this study, the investigators will investigate two types of aerobic exercise (i.e., vigorous-intensity exercise and moderate-intensity exercise) under different exercising frequencies (i.e., regular exercising pattern and weekend warrior). Individuals with chronic insomnia and depressive symptoms will be recruited and randomly allocated into 5 groups: 1) attention control group (stretching exercise), 2) moderate intensity exercise performed thrice weekly (MIE×3/wk), 3) moderate intensity exercise performed once weekly (MIE×1/wk), 4) vigorous intensity exercise performed thrice weekly (VIE×3/wk), and 5) vigorous intensity exercise performed once weekly (VIE×1/wk). Intervention will be maintained for 12 weeks. Outcome assessments will be conducted at baseline, 6 weeks and 12 weeks after the intervention. Outcomes including depressive status, chronic insomnia, objective sleep quality and pattern (measured by Actigraphy), subjective sleep quality (measured by Epworth sleepiness scale, insomnia severity index, PSQI), anxiety status (measured by HADS and GAD-7), quality of life (measured by SF-12), attention level (measured by computer attention test), exercise enjoyment (measured by physical activity enjoyment scale), habitual physical activity level (measured by IPAQ), aerobic fitness (measured by metabolic cart), body adiposity (measured by DXA), blood chemistry, adherence, medication usage, and adverse events will be measure in this study. This proposed study will provide pilot evidence for the benefits, effectiveness, safety, adherence, and sustainability of low-frequency vigorous aerobic exercise. the investigators expect the low-frequency exercise modality will enhance the practical suitability of aerobic exercise and will provide evidence for weekend warrior aerobic training strategy as a new exercise option in the management of elderly insomnia and depression.
