During the course of the study, 10 subjects in the exercise group dropped out. Remaining subjects improved on the physical tests. Arm ergometry performance showed improved power output and increased heart rate, meaning they could perform more work at a specific heart rate. Muscle strength increased in all muscle groups and was significant in all but the deltoids. Quality of life improvements also showed positive improvements as self-reports of stress, pain, and depression all decreased while physical self-concept and overall quality of life increased.
