The level of daily activities is a determining factor and the degree of autonomy in movement is an important component that influences quality of life. Pedometry represents an alternative tool for estimating the degree of this activity.Aims: To compare the values, obtained by pedometry of COPD patients (GOLD stage III and IV) with the values of healthy subjects from the Euroregion Banat.Material and methods: We used pedometers to monitor 14 patients with COPD (not included in pulmonary rehabilitation) and 32 healthy subjects for a week, registering daily level and intensity of movement and detecting aerobic effort. Both groups had comparable demographic data and similar occupations.Results: Healthy individuals showed a significantly higher average of steps over a full week compared with COPD patients (6497±1866 vs. 3992±295, p <0.05). In both groups the number of steps was lower during the week-end compared with working days: 4754±2322 vs 7185±2396 steps for the control group, and 2135±697 steps vs 4736±175 steps in COPD patients (p <0.05). 52.77% of the normal subjects have made an aerobic effort at least one day in a week and only 13.88% performed a constant aerobic effort. Patients with COPD couldn't perform an aerobic exercise at all.Conclusions: We found a decrease in intensity of daily activity in healthy subjects, compared with data from literature, suggesting an increase of the sedentary style in general population. The degree of physical activity is significantly reduced in COPD compared with healthy people on both levels: aerobic and anaerobic effort. For both groups, periods of week-end reveal the lowest activity level. ER -
