Exercise training group
Inactive control group
Exercise training is performed in subgroups of 6 patients supervised by two physiotherapists. Exercise prescription consisted of a 15-min warm-up, walking up to 30 min, followed by a 15-min cooling-down. The exercise intensity during the first 2 weeks corresponds to 55% at 65% of the HR peak reached at the baseline exercise test. In posterior sessions, individual adjustments are performed with gradual increases in order to reach the adequate target HR training intensity, as determined by the Karvonen formula {(maximal HR - HR at rest) x 50 to 70% + HR at rest}. Exercise training is performed in the morning, three times a week (on alternate days) for a total of 12 weeks (36 sessions).
