“…Relativamente a outras formas de avaliação do treinamento físico regular no paciente portador de DPOC, existem alguns resultados controversos, como o estudo de Belmam et al (5) , que falhou em demonstrar aumento quantitativo de enzimas oxidativas. Entretanto, recente publicação de Maltais et al (8) conseguiu determinar aumentos significativos de enzimas oxidativas, diminuição do volume minuto (VM) e da produção de lactato nos pacientes submetidos a 12 semanas de treinamento físico.…”

“…O peso inicial a ser utilizado foi determinado prévia e individualmente pelo teste incremental, com o intuito de trabalhar inicialmente com 50% da carga máxi-ma sustentada pelo paciente; § 3ª etapa: treinamento de membros inferiores desenvolvido na bicicleta ergométrica com tempo predeterminado e evolução semanal. A potência a ser desenvolvida foi determinada individual e previamente ao início do programa, objetivando um trabalho de 50% da capacidade física máxima do indivíduo (5,6) ; § 4ª etapa: posturas de alongamento da musculatura utilizada durante a sessão.…”

“…For many years, it was argued that work intensity during exercise training was too low in COPD to accomplish these adaptations in peripheral muscles. Data from BELMAN and KENDREGAN [22] were the main support for this statement, because the study failed to demonstrate changes in muscle enzymes after exercise training. However, it should be noted that their training programme had probably a low training intensity.…”

Pulmonary rehabilitation programmes aim at improving exercise capacity, activities of daily living, quality of life and perhaps survival in patients with chronic obstructive pulmonary disease (COPD). Recently, well-designed studies investigated and confirmed the efficacy of comprehensive pulmonary rehabilitation programmes, including exercise training, breathing exercises, optimal medical treatment, psychosocial support and health education. In the present overview, the contribution of exercise training in clinical practice to the demonstrated effects of pulmonary rehabilitation is discussed by means of six basic questions. These include: 1) the significance of exercise training; 2) the optimal intensity for exercise training; 3) prescribing training modalities; 4) the effects of exercise training combined with medication, nutrition or oxygen; 5) how training effects should be maintained; and 6) where the rehabilitation programme should be performed: in-patient, out-patient or homecare? First, exercise training has been proven to be an essential component of pulmonary rehabilitation. Training intensity is of key importance. High-intensity training (>70% maximal workload) is feasible even in patients with more advanced COPD. In addition, the effects on peripheral muscle function and ventilatory adaptations are superior to low-intensity training. There is, however, no consensus on the optimal training modalities. Both walking and cycling improved exercise performance. Since peripheral muscle function has been recognized as an important contributor to exercise performance, specific peripheral muscle training recently gained interest. Improved submaximal exercise performance and increased quality of life were found after muscle training. The optimal training regimen (strength or endurance) and the muscle groups to be trained, remain to be determined. Training of respiratory muscles is recommended in patients with ventilatory limitation during exercise. The additional effects of anabolic-androgenic drugs, oxygen and nutrition are not well-established in COPD patients and need further research. In order to maintain training effects, close attention of the rehabilitation team is required. The continuous training frequency necessary to maintain training effects remains to be defined. At this point in time, out-patient-based programmes show the best results and guarantee the best supervision and a multidisciplinary approach. Future research should focus on the role of homecare programmes to maintain improvements.

“…It was thought initially that the ventilatory restriction to exercise in COPD subjects would limit the physiological benefits of pulmonary rehabilitation [6]. However, it has subsequently been shown that exercise at a higher intensity, beyond the anaerobic threshold in COPD, leads to greater improvements in training [7].…”

Increased ventilation with NiIPPV does not necessarily improve exercise capacity in COPD

Increased ventilation with NiIPPV does not necessarily improve exercise capacity in COPD. M.P. Highcock, J.M. Shneerson, I.E. Smith. #ERS Journals Ltd 2003. ABSTRACT: Evidence that noninvasive intermittent positive-pressure ventilation (NiIPPV) improves exercise capacity in chronic obstructive pulmonary disease (COPD) is limited. The effectiveness of different ventilators in this setting has not been studied.Three bilevel pressure support ventilators (Bipap S/T 30, Nippy2 and Vpap II ST), applied via a mouthpiece, were compared during submaximal treadmill exercise in eight subjects with COPD. Subjects walked to exhaustion with each of the ventilators and while breathing through the mouthpiece alone, in random order. In addition, four unencumbered walks were performed.The unencumbered distance (mean¡SD) walked was 259¡123 m. With the mouthpiece alone this decreased to 211¡96 m and fell further to 145¡76 m with NiIPPV. There was no difference between the brands of ventilator. At the break-point of exercise, significant increases were seen in tidal volume and minute ventilation in the ventilator walks compared with the mouthpiece alone.Noninvasive intermittent positive-pressure ventilation increased ventilation but did not improve exercise capacity in the subjects in this study. No significant differences were seen between the ventilators. The effectiveness of this technique and the optimal method of assistance require further clarification. Eur Respir J 2003; 22: 100-105.
