| Outline of Final Research Achievements |
We evaluated the validity of a triaxial accelerometer, Active Style Pro HJA-750C; (HJA). The values of physical activity (PA) measured by HJA were significantly correlated with those by 2 already validated accelerometers, and the validity of HJA was confirmed. The PA on rainy day was suppressed but that on holiday was not. Analysis with at least 3 days was required for repeatability. In COPD patients, the walking time, walking distance and total step count were lower but the walking velocity was not different compared to healthy subjects. The mMRC>=2 could predict the condition of physical inactivity. Additional administration of bronchodilator enhanced PA at >=3.0 and >=3.5METs, and the enhancement was greater in patients with better pulmonary function. An improvement in PA at >=2.0METs was seen with the combination drug of 2 bronchodilators compared to the single agent.
