Thirty-four subjects (28 men, six women; six blacks, 28 whites) completed 4 months of training and provided accelerometry data at all three measurement points for SE-UBR (n=10), ED-UBR (n=15), and ED-Chair (n=9). This group was similar to the larger group of 49 with respect to mean age (73±8 years), FEV1, % predicted (58±18), DLco % predicted (67±21), residual volume (RV)/total lung capacity (TLC; 0.54±0.11) and BMI (28±7). Twenty-four percent were overweight and 30% were obese.
