Abstract
Introduction: the success of long-term ET programs resides in the integration between exercise prescription and patients' compliance with home training. Aim: to evaluate two methods to help understanding and maintaining the exercise (walking) intensity. Methods: 36 COPD patients (9F,27M) participated to the ET program (age 72 ±8; FEV1% 48±12). T0= first evaluation: 6MWD, tests on treadmill to evaluate walking distance covered in twenty minutes (20MWD) and maximal speed, monitoring of physical activity (Armband). Patients were then divided in 2 groups for the home ET program: A1= speed walking marked by a metronome; A2=covering a known distance in a fixed time. Test were repeated after 5 and 12 months (T5;T12). Control group: 23 well matched COPD not partecipating in ET (8F,15M,age 69±7,FEV1% 52±11) Results: Group A1-A2.
