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). SGQR score FEV1 (L/sec) Daily METs Physical activity > 3 METs (min) Distance (m) Speed (Km/h) T0 35,2±4 1,06±0,08 1,26±0,04 22,2±5,4 449±50 1,7±0,12 T5 27,4±2,6* 1,13±0,07* 1,38±0,06*** 44,4±10,2** 891±91*** 2,7±0,2*** METs Metabolic Equivalent: 3.5 ml O2/Kg/min or 1 Kcal/kg/h Δ % Distance Δ % Speed A1 15,1±6* 14,5±5,7* A2 1,9±6,7 1,8±5,5 Group B: no significant change.
