Objective The aim of this study was to investigate the effects of exercise and exercise plus acupuncture on chronic insomnia. Material and Methods suggest replacing with “effects of” no feasibility things are reported chronic insomnia were randomized to a 12-week treatment with exercise or exercise plus acupuncture. Exercise treatment included 50 minutes of moderate-intensity aerobic exercise (50% of reserve heart rate), on a treadmill, 3 times/wk. Exercise plus acupuncture treatment included the exercise protocol plus acupuncture once per week. Pre- and post-treatments measures included insomnia severity index (ISI), Pittsburgh sleep quality index (PSQI), polysomnography (PSG), 10 days-sleep diary, state-trait anxiety inventory, Beck depression inventory, quality of life (SF-36), and morning cortisol level. Results No group by time interaction was found for insomnia severity, sleep, mood or quality of life. Significant time differences (p<0.05) were observed for ISI, PSQI, and some variables of sleep diary. Polysomnography data showed a decrease in rapid eye movement (REM) latency after the interventions. Significant time improvements were also observed for mood, anxiety, depression, and quality of life. A significant moderate correlation was found between changes in the ISI and morning cortisol level. Conclusion There were no significant differences between treatments on insomnia severity, sleep, mood or quality of life. Exercise and exercise plus acupuncture were efficacious for decreasing insomnia severity to subthreshold insomnia. Greater reduction in morning cortisol was associated with a greater reduction on insomnia severity across both treatments.
