“…The modified MRC dyspnea scale was used [14]. This is scored on a 5-point scale from 0 to 4, where grade 0 describes the subject as ‘not troubled by shortness of breath except with strenuous exercise’, and grade 4 describes the subject as ‘too breathless to leave the house or breathless when dressing or undressing’.…”

Background: Exhaled breath condensate (EBC) 8-isoprostane levels were found increased in chronic obstructive pulmonary disease. However, the relation between EBC 8-isoprostane and parameters which have a known predictive value in COPD, remains vastly unknown, and so does subsequently its clinical value. Objectives: To investigate the relationship between 8-isoprostane level in EBC and clinical parameters, radiological indices and airway inflammation in COPD patients. Materials and Methods: We studied 18 COPD patients (all ex-smokers) and 12 healthy controls (5 ex-smokers and 7 never-smokers). All patients underwent clinical evaluation, sputum induction, high-resolution computed tomography (HRCT) of the thorax and EBC 8-isoprostane measurement. 8-Isoprostane levels were correlated with markers that reflect disease severity, such as dyspnea severity, FEV₁ (%pred), emphysema changes and bronchiectasis in HRCT. Emphysema was quantified as the percentage of lung area with attenuation values < –950 Hounsfield units. Results: 8-Isoprostane levels were significantly elevated in EBC of patients with COPD [mean (SE) 18.1 (2) vs. 5.6 (0.7) pg/ml, p = 0.0001], irrespective of lung function impairment. 8-Isoprostane levels were correlated with emphysema score in HRCT (r² = 0.43, p = 0.001) as well as with Medical Research Council dyspnea scale score (rho = 0.61, p = 0.005). Conclusion: Our findings suggest that EBC 8-isoprostane levels may reflect the extension of lung emphysema in COPD patients. In this respect, further investigation is required in order to evaluate the possible role of EBC 8-isoprostane in assessing disease progress in COPD patients.

“…For a subjective evaluation of perceived exertion, Borg rating scale from 6 to 20 was used. The Borg scale has been found valid for use on COPD-patients by Martinez et al (2000). The heart rate was measured every 5 s during the tests by Polar ® Accurex watches (Polar Electro, Finland) and determined as the highest observed value at the end of the peak exercise tests.…”

Aerobic high intensity one and two legs interval cycling in chronic obstructive pulmonary disease: the sum of the parts is greater than the whole

The purpose of this study was to investigate whether individual leg cycling could produce higher whole body peak oxygen uptake (VO(2peak)) than two legs cycling during aerobic high intensity interval training in chronic obstructive pulmonary disease (COPD) patients. Nineteen patients trained in 24 supervised cycling sessions either by one leg training (OLT) (n = 12) or by two legs training (TLT) (n = 7) at 4 x 4 min intervals at 85-95% of peak heart rate. Whole body VO(2peak) and peak work rate increased significantly by 12 and 23% in the OLT, and by 6 and 12% in the TLT from pre- to post-training, respectively, and were significantly greater in the OLT than the TLT (P < 0.05). The present study demonstrates that one leg aerobic high intensity interval cycling is superior to two legs in increasing whole body VO(2peak), indicating a muscle rather than a cardiovascular limitation to VO(2peak) in these COPD patients.

“…To rule out such factors, it would be necessary to make a comparison between anxious and non-anxious subjects or between experienced and naïve subjects. A study related to the use of the ratings scales compared the reliability of dyspnoea perceptions using four types of scales, in literate and illiterate COPD patients [29]. There were no significant differences, although only spirometry and not exercise was performed.…”

There are conflicting reports on the reproducibility of the visual analogue scale (VAS) and the modified Borg scale for the estimation of breathlessness during exercise. In an attempt to clarify the situation, two groups of healthy subjects undertook a progressive exercise test either daily (Group A) or weekly (Group B) on 10 separate occasions. Breathlessness was estimated every 1 min using the VAS. After 10 occasions, both Group A (P<0.05) and Group B ( P <0.01) showed a significant increase in the mean intercept of the breathlessness/ventilation (VAS/ V (I)) relationship. The increase was not progressive; using change point regression, reproducible values were found to occur after approximately the fifth occasion in both subject groups. As the slope of the VAS/ V (I) relationship was highly reproducible and did not change with repeat testing, it would appear that at least two mechanisms are involved in the generation of the sensation of breathlessness. A decrease in the exercise heart rate over the same time period was significantly correlated with changes in the VAS/ V (I) intercept in both groups (P <0.01 and P <0.005 respectively). The relationship is unlikely to be causal, but may be indicative of a common underlying mechanism. It is suggested that breathlessness scores are likely to decrease as a direct result of repetitive testing over, on average, the first five periods of assessment. On the basis of this study, it may be inferred that a physiological mechanism contributes to the modulation of breathlessness during repetitive exercise testing.
