Comparison of Effects of Strength and Endurance Training in Patients with Chronic Obstructive Pulmonary Disease

Abstract

We determined the effect of different exercise training modalities in patients with chronic obstructive pulmonary disease, including strength training (n = 17), endurance training (n = 16), and combined strength and endurance (n = 14) (half of the endurance and half of the strengthening exercises). Data were compared at baseline, the end of the 12-week exercise-training program, and 12 weeks later. Improvement in the walking distance was only significant in the strength group. Increases in submaximal exercise capacity for the endurance group were significantly higher than those observed in the strength group but were of similar magnitude than those in the combined training modality, which in turn were significantly higher than for the strength group. Increases in the strength of the muscle groups measured in five weight lifting exercises were significantly higher in the strength group than in the endurance group but were of similar magnitude than in the combined training group, which again showed significantly higher increases than subjects in the endurance group. Any training modality showed significant improvements of the breathlessness score and the dyspnea dimension of the chronic respiratory questionnaire. In conclusion, the combination of strength and endurance training seems an adequate training strategy for chronic obstructive pulmonary disease patients.

Cardiopulmonary stress during exercise training in patients with COPD

“…However, the load progression observed in the present study was similar to that achieved in other studies, including COPD patients, which showed a significant effect on lower limb muscle force [2,5].…”

“…However, in addition to walking and cycling, other exercise modalities have been described during PR for COPD patients, e.g. resistance training [2], callisthenics [3], arm cranking [4] and stair climbing [5]. In clinical rehabilitation, a combination of several of these exercises, is often applied.…”

“…Regarding the distance covered in the 6mwt, the present study found no significant difference between pre-and post-pulmonary rehabilitation distances, unlike the results obtained in many studies in literature which found that aerobic training was able to increase submaximal exercise capacity 11,17,20,21 .…”

“…other pulmonary rehabilitation protocols also found an improvement in Qol in asthmatic and Copd patients [20][21][22][23][24] . wijkstra et al 25 used the CRQ to investigate how a home exercise program could interfere in the quality of life of Copd patients.…”

“…different protocols with fewer training sessions, such as twice or three times a week 13,17,19,20 , have also proved to be efficient.…”
