The researchers wanted to know what effect, if any, simply thinking and learning about exercise and health would have on the subjects. The exercise and video-viewing sessions were separated by one week.

Subjects completed an assessment of cognitive performance immediately before and after each session. The assessment evaluated aspects of cognitive functioning that are thought to be responsive to exercise, such as verbal processing, attention span, short-term memory and motor skills.

The COPD group showed marked improvement in one area - verbal fluency - after exercising for 20 minutes.
