Cognitive and psychological outcomes of exercise in a 1-year follow-up study of patients with chronic obstructive pulmonary disease.

This study evaluated outcomes of self-directed exercise activity on cognitive functioning and psychological well-being among 28 adults with chronic obstructive pulmonary disease (COPD). Participants had completed an intensive 10-week program of exercise training and were given an exercise prescription to follow. One year later, participants completed comprehensive assessments of physical, cognitive, and psychological functioning. At follow-up, 39% (n=11) had continued with a regular program of moderate intensity exercise. Repeated measures analysis of variance indicated that exercise adherent participants maintained gains they had achieved in the initial exercise intervention, but nonexercise participants experienced declines in functional capacity, cognitive performance, and psychological well-being. Continued exercise among patients with COPD is associated with maintenance of physical, cognitive, and psychological functioning.

Short-term effects of exercise and music on cognitive performance among participants in a cardiac rehabilitation program.

OBJECTIVE: Exercise has been associated with improved cognitive performance among patients with coronary artery disease. Music listening has been associated with enhanced cognitive functioning among healthy adults. This study evaluated the combined influence of exercise and music listening on cognitive performance among patients in cardiac rehabilitation (CR). DESIGN AND SETTING: Using a within-subjects repeated measures design, this study was conducted in an outpatient University-based CR facility. SAMPLE: Thirty-three men and women (mean age = 62.6 +/- 10.5 years) participated in this study. METHODS: Participants completed 1 exercise session accompanied by music and a second exercise session without music. Order of conditions was assigned randomly. Before and after each exercise session, participants completed a brief assessment of depression and anxiety, and a cognitive test of verbal fluency. RESULTS: The music condition was associated with significant improvements in verbal fluency, but the no-music control condition was not associated with cognitive change. CONCLUSION: The study provides preliminary evidence of the combined benefit of exercise and music listening for cognitive performance among patients in CR.
