The efficacy of two methods of exercise training in moderate/severe COPD. Introduction: Exercise training (ET) is the key component of respiratory rehabilitation. In cost-benefit terms the ET programs are advantageous if carried out at home. This can be difficult for patients, especially in terms of understanding exercise intensity. Aim: To evaluate two methods of home ET (walking). Methods: 33 COPD. Group A: 19 (7F,12M) participated to the ET program (age 74 ±1,3; FEV1% 46,4±3,6); Group B: 14 (2F,12M) did not participate (age 71 ±1,2; FEV1% 55,4±3,5). After the initial evaluation and the assessment of optimal speed walking (T0), patients received a home ET program and were studied after 5 months (T5), by means of spirometry, Saint George Questionnaire (SGQR), treadmill walking test and Armband to monitor physical activity.

Abstract
The efficacy of two methods of exercise training in moderate/severe COPD. Introduction: Exercise training (ET) is the key component of respiratory rehabilitation. In cost-benefit terms the ET programs are advantageous if carried out at home. This can be difficult for patients, especially in terms of understanding exercise intensity. Aim: To evaluate two methods of home ET (walking). Methods: 33 COPD. Group A: 19 (7F,12M) participated to the ET program (age 74 ±1,3; FEV1% 46,4±3,6); Group B: 14 (2F,12M) did not participate (age 71 ±1,2; FEV1% 55,4±3,5). After the initial evaluation and the assessment of optimal speed walking (T0), patients received a home ET program and were studied after 5 months (T5), by means of spirometry, Saint George Questionnaire (SGQR), treadmill walking test and Armband to monitor physical activity. Patients were further divided in 2 groups: A1) speed walking marked by a metronome; A2) covering a known distance in a fixed time. Results: Group A (Table1), (Table 2).
