Mean short-form Health Survey Questionnaire (SF-36) scores for quality of life subscales before and after exercise training. At baseline (straight line), mean SF-36 scores were significantly reduced in comparison to respective values from a normal population (dotted line). After 15 weeks (dashed line), 5 scales of the SF-36 questionnaire improved significantly: physical functioning, general health perception, social functioning, mental health and vitality. P-values are indicated vs. baseline. No significant improvement was found for role emotional (ROLEM), role physical (ROLPH) and bodily pain (PAIN) after training. With Bonferroni adjustment, values of P < 0.005 were considered statistically significant. Data were available and were included in the analyses for 21 patients studied at baseline and for 18 patients studied at 15 weeks.
