“…The results of our study confirmed previous observations that both hand grip strength and endurance are diminished in COPD patients compared with healthy subjects. 2 , 20 – 22 Decreased endurance was possibly caused not only by reduced weight or amount of FFM, but also by muscle dysfunction. This hypothesis is evidenced by the fact that after correction for weight and FFM, there were significant differences between groups in endurance (expressed as AUC), while not in the case of strength, even though there were no significant differences between the groups in weight or amount of FFM.…”

PurposePatients with COPD present peripheral muscle dysfunction and atrophy, expressed as muscle strength and endurance reduction. The goal of this study was direct dynamometric assessment of hand grip endurance and strength in relation to the stage of disease, multidimensional predictors of mortality, and 6-minute walk test (6MWT). To the best of our knowledge, there has been no previous study determining these parameters.Patients and methodsIn this observational study, 58 consecutive outpatients with stable COPD and 25 volunteers without respiratory problems were compared. All COPD subjects underwent a comprehensive examination to determine COPD severity, prognostic scales, and 6MWT. Body composition, basic spirometric parameters, and hand grip strength and endurance were determined in all study participants.ResultsPatients in the COPD group had a 15% decrease in maximum strength (P=0.012) and a 28% decrease in area under the force/time curve (AUC) of the endurance test (P<0.001) compared to the control group. Dynamometric parameters were significantly negatively associated with the stage of disease and values of multivariable prediction indexes, and positively associated with the results of 6MWT. In most cases, closer associations were found with AUC than with 6MWT and in the gender-specific groups.ConclusionBoth hand grip strength and endurance are impaired in COPD patients in comparison with the control group. In particular, AUC could be considered as an attractive option not only to assess exercise capacity but also as a predictive marker with a better prognostic value than 6MWT in COPD patients. This is the first study to observe the dependence of hand grip endurance on combined COPD assessment.

“…The identification of other factors that contribute to variability in dyspnea during exercise could result in improvement in a patient’s exercise capacity [2]. In 2016, Hodonska et al, [3] found a decreased level of exercise tolerance in patients with severe COPD. The study also concluded that exercise, assessed by the average of the 6 minutes walk distance (6MWD), could cause greater desaturation in patients with COPD compared with the healthy person [3].…”

BACKGROUND:Patients with chronic obstructive pulmonary disease (COPD) exhibit persistent dyspnea in daily activities and irreversible airflow obstruction. These will finally lead to an inability to carry on daily activities and markedly decrease their quality of life. Endurance training was considered as therapy modality to alleviate several symptoms experienced by COPD patients.AIM:This study aims to identify the impact of lower-limb exercise on dyspnea and spirometry test results in COPD patients.METHODS:We performed a quasi-experimental study in July 2017 on 20 stable COPD patients divided both in group C and D according to GOLD 2017 criteria. Patients were given an individualised dose of stationary cycling twice a week for one month in which every session lasted 5-20 minutes gradually. Before and after rehabilitation program, pulmonary function tests were measured by spirometry to obtain per cent predicted of Forced Expiratory Volume in 1 second (FEV1), Forced Volume Capacity (FVC), Peak Expiratory Flow (PEF) and Forced Expiratory Flow at 25-75% of the pulmonary volume (FEF25-75), and dyspnea was measured by the mMRC index. Statistical analysis was performed by Wilcoxon and T-dependent test.RESULTS:Baseline value of FVC (49.6 ± 21.6%) increased significantly to 59.65 ± 16.53% after one month of endurance training program (p = 0.01). Surprisingly, there was also a significant increase in FEV1 value from 46.9 ± 21.7 to 52.9 ± 20.7% (p < 0.005). The increase of FVC and FEV1 in group C was slightly higher than in group D although not statistically significant (p = 0.29; p = 0.25 respectively). However, no difference was observed in PEF and FEF25-75 value (p > 0.05). Patients’ dyspnea scale also showed significant improvement (p < 0.001) from mMRC median scale 2 (range 1-3) to 1 (range 0-2) in both groups C and D. There was no exacerbation found during rehabilitation program.CONCLUSION:Twice a week lower-limb endurance training for one-month improved dyspnea and pulmonary function test results in COPD patients safely and effectively.

Introduction. The incremental shuttle walking test (iSWT) has been widely used in different health conditions. Because of the learning effect, the test should be performed at least twice. However, there is no formal recommendation or consensus on the rest interval that should be used between the tests. Therefore, the aim of this study was to systematically review the most common rest intervals applied for iSWT in adult and elderly individuals with different health conditions. Methods. We performed a systematic review based on the PRiSMA protocol, registered in PRoSPERo. Searches were conducted in 8 electronic databases (MEdLiNE via PubMed and ovidSP, PEdro, LiLACS, SciELo, Cochrane, CiNAHL, Web of Science, and Scopus) by using specific terms. Results. We initially found 1538 references, of which 75 met the inclusion criteria. Numerous studies did not report the rest interval between the tests and therefore could not be included in the review. of the 75 studies, 41 evaluated individuals with respiratory dysfunctions, mainly chronic obstructive pulmonary disease. Most of them (n = 57) used a 30-minute interval, followed by a 20-minute interval (n = 6) and a 15-minute interval (n = 4). Conclusions. This systematic review demonstrates that many studies did not point out the rest interval for iSWT. Although there was a predominance of a 30-minute interval between the tests, future research is needed to understand the implications of the resting interval on iSWT outcomes.
