Patients continued attending the training sessions during the assessment weeks. Comparisons between the 3 moments were done including and excluding the period of the training sessions.Results: Excluding the training session period, patients spent more time in physical activities (>2 METs) on TD (49 and 49 min) and on NTD (37 and 42 min) in the 1st and 2nd month of exercise training respectively in comparison to baseline (34min) (p≤0.01). Figure 1 shows the percentage of change in daily physical activity (METs/10 min) in the TD and NTD in comparison to baseline.Conclusion: Exercise training provides an increase in daily physical activity of patients with COPD not only in the training days but also in the non-training days. Hence, exercise training provides acute improvement in patients’ physical activity level, even on the days they do not have to perform planned exercises. ER -
