Changes in Exercise Tolerance, Health Related Quality of Life, and Peripheral Muscle Characteristics of Chronic Obstructive Pulmonary Disease Patients After 6 Weeks' Training

Meta-analysis on the Physiological Benefits and Quality of Life of Muscle Training in Patients with Chronic Obstructive Pulmonary Disease

“…This finding is contrary to that found by other investigators who found significant differences in the 6-minute walk only in the resistance training group [11].…”

“…However, although the effect is not significant between the types of exercise, when analyzing the moderating variables for this variable, it is found that there is a significant relationship with age but inversely, being that the older the effect of the training on the LV, another of the moderating variables that could affect are the weeks of treatment, in which it was found that the greater the duration of the program, the greater the effects of training, besides another variable that produces an affectation but in an inverse way, it is the number of sessions, that is, the greater the number of sessions, the lower the VE, the peripheral myopathy in COPD, shows a predominance of anaerobic metabolism in the muscle, involving more weeks of training, and more sessions We can reverse the detraining [4], and it is observed in studies that showed age ranges of the subjects less than the other studies and a response Significant in VE [11,13].…”

Pulmonary Rehabilitation in COPD: Effect of 2 Aerobic Exercise Intensities on Subject-Centered Outcomes—A Randomized Controlled Trial

“…International guidelines present evidence of physiological benefits associated with higher aerobic training intensities, 41 in accordance with historical studies by Casaburi et al, 42 Maltais et al, 43 Puente-Maestu et al, 44 and Gimenez et al, 45 but also more recently by Lacasse et al, 32 Laviolette et al, 28 Bernard et al, 34 Montes de Oca et al, 36 Dourado et al, 37 Arnardóttir et al, 38 Foglio et al, 39 Normandin et al, 40 and Hsieh et al 46 Those studies reported improvements in the 6MWT, incremental exercise test, and constant-load exercise test with a pulmonary rehabilitation program but without any evidence of significant differences in these outcomes as an effect of the aerobic training intensities applied. On the other hand, more research is needed focusing on patients' goals.…”

“…There is evidence of a positive effect on HRQOL, as shown by studies by Bernard et al, 34 Pereira et al, 35 Montes de Oca et al, 36 Dourado et al, 37 Arnardóttir et al, 38 and Foglio et al, 39 , even considering the wide range of intensities in those heterogeneous pulmonary rehabilitation program interventions (type, modality, duration, and frequency). The multi-center study by Laviolette et al 28 with 168 subjects with COPD also found improvement in the SGRQ after the pulmonary rehabilitation program but lacked any description of the exercise intensity applied.…”

Muscle fibre type shifting in the vastus lateralis of patients with COPD is associated with disease severity: a systematic review and meta-analysis

“…One additional publication, of which we were aware, incorrectly did not appear in the search results because fibre typing was not mentioned in the abstract 6. Of these 39 papers, 20 were excluded for the following reasons: 15 were false positive hits (eg, fibre type proportions were not studied or they were studied in skeletal muscles other than the quadriceps femoris), 2 had overlapping data (Montes de Oca et al 7 8 and Gosker et al 9 10) and 3 because of co-morbidity 6 11 12. The remaining 19 articles were included in the current study (table 1), all biopsies being obtained from the vastus lateralis.…”
