[Exercise training in chronic obstructive pulmonary disease. Comparative study of aerobic training of lower limbs vs. combination with upper limbs].
A prospective, randomized and controlled study has been performed in 28 patients with severe COPD. A group of 14 has been trained with their lower limbs (LL), while another similar group of 14 patients was also trained with their upper limbs (UL). Results showed improvement in both groups in the endurance test for LL, dyspnea scale, efficiency and muscular working capacity. A considerable improvement was observed in the oxygen uptake at the anerobic threshold (VO2AT) which suggests a training effect, expressed through an improvement in exercise tolerance. Only the group who trained UL showed a remarkable improvement in the dyspnea scale, endurance test and maximal static mouth pressure, showing a better intrinsic working capacity and participation of the UL muscles producing those manoeuvres. At the end of training, quality of life was significantly increased and the hospitalization rate was lower in both groups. According to these findings, it is suggested that patients with severe COPD included in training programmes add UL exercises to the LL usually carried out.
