The aim of this study was to evaluate the effects of moderate aerobic exercise training on sleep, depression, cortisol, and markers of immune function in patients with chronic primary insomnia. Twenty-one sedentary participants (16 women aged 44.7 ± 9 years) with chronic primary insomnia completed a 4-month intervention of moderate aerobic exercise. Compared with baseline, polysomnographic data showed improvements following exercise training. Also observed were reductions in depression symptoms and plasma cortisol. Immunologic assays revealed a significant increase in plasma apolipoprotein A (140.9 ± 22 to 151.2 ± 22 mg/dL) and decreases in CD4 (915.6 ± 361 to 789.6 ± 310 mm[superscript 3]) and CD8 (532.4 ± 259 to 435.7 ± 204 mm[superscript 3]). Decreases in cortisol were significantly correlated with increases in total sleep time (r = -0.51) and REM sleep (r = -0.52). In summary, long-term moderate aerobic exercise training improved sleep, reduced depression and cortisol, and promoted significant changes in immunologic variables.
Programming is an essential part of library services. Having a regular program at the library and a wide distribution list raises awareness of the library to those associated with the university and beyond. Through programming, libraries demonstrate the vital role they play in the community. The ASU Science Book Discussion began meeting in the summer of 2011.
This presentation was given at the Montana Library Association conference in Billings, MT in 2011 and the Arizona Library Association conference in Tucson, AZ in 2011.
