Efectos de diferentes estrategias de entrenamiento al ejercicio sobre parámetros antropométricos según el fenotipo del paciente con EPOC

OBJECTIVE: To analyse the effect of the application of different modes of exercise training on two anthropometric parameters in a group of patients with chronic obstructive pulmonary disease (COPD), categorised according to their phenotype (with or without predominance of emphysema). METHODOLOGY: Sixty-four patients with stable COPD (average age of 64.1 ± 6.8 years) that presented moderate-severe airflow obstruction, undertook an exercise training programme, randomly distributed in three groups: resistance (n=21; aerobic bicycle training to 70% of their initial maximum VO2), strength (n=22; five weight raising exercises to 70-85% of the initial 1-RM test, including arm and leg muscle groups) and mixed (n=21; combination of the previous). They were subdivided into COPD patients with predominance of emphysema (n=32) or without emphysema (n=32) according to clinical, functional and radiological criteria. The changes in weight and body mass index (BMI) were measured as anthropometric parameters initially, and after 12 weeks of training. RESULTS: COPD patients without emphysema whose training included aerobic type exercises (resistance and mixed groups) experienced a reduction of BMI (-0.43 ± 1.45 and -0.82 ± 1.04; p
