“…Despite being the primary morbid symptom of chronic lung disease, and hence a key target for improvement with pulmonary rehabilitation, we know little about the significance of exercise training intensity per se on exertional dyspnoea . Much of this uncertainty can be accounted for by the way in which dyspnoea is assessed in pulmonary rehabilitation studies.…”

“…From a physiological standpoint, an intervention that enables a fixed level of energy expenditure with a reduced efferent activity to ventilatory muscles should provide the best option for dyspnoea relief and in this respect high‐intensity training (assuming compliance) would be preferred. However, the perception of dyspnoea is likely to be modulated by complex central neural processing of non‐ventilatory afferent information (e.g.…”

“…However, the perception of dyspnoea is likely to be modulated by complex central neural processing of non‐ventilatory afferent information (e.g. from exercising muscles) as well as higher centre functions relating to cognition, emotion and psychopathology, making these non‐respiratory factors preferred targets for achieving pulmonary rehabilitation (PR) efficacy . Alternatively, as the benefits of exercise on psychosocial status are well recognized, a focus on low‐intensity (less stressful) training may be indicated.…”

Exercise training in COPD: What is it about intensity?

Most of the current guidelines for pulmonary rehabilitation recommend higher, over lower, intensity exercise training for COPD. Typically, we consider intensity of exercise training to be a key component of any exercise training programme. Whilst studies of young individuals have demonstrated that higher exercise training intensity results in greater improvements in exercise capacity, the evidence for older patients is not so clear cut. In COPD, there is limited evidence regarding the optimal intensity of exercise training. Using both physiological (peak exercise capacity) and patient-centred (e.g. quality of life) outcomes, it remains inconclusive if higher intensity exercise training bestows any greater benefit than low-intensity exercise. If we examine the data from interval training studies, which used both high-and low-intensity interval and continuous exercise, we are able to generate more data for comparison. Unfortunately, these data are challenging to interpret due to heterogeneity in how interval training was prescribed. However, when we normalize the interval training data for training volume and examine the change in peak cycling power, there is a relationship between training intensity and increase in peak power (W peak , r = 0.68, P < 0.05). Hence, whilst there is an inconclusive amount of evidence to support this intervention based on studies that only examined high-versus lowintensity continuous exercise, the additional data from interval training studies would suggest that higher intensity may be superior in terms of increases in W peak . Future studies should focus on establishing a threshold and an optimal training intensity for COPD.

Background: Multidrug-resistant tuberculosis (MDR-TB) continues to be a global health catastrophe. This prospective study examines the subjective impact of the disease as experienced by patients using the Saint George’s Respiratory Questionnaire. Methodology: The study involved 244 patients diagnosed with drug-sensitive and drug-resistant pulmonary tuberculosis over a 10-year years. These patients were administered the Saint George’s Respiratory Questionnaire, which was evaluated in comparison between the two groups to determine the progressive impact of disease in patients with MDR-TB compared to patients with drug-sensitive tuberculosis (DS-TB). Results: The analysis showed that patients with MDR-TB had statistically significantly higher symptomatic activity and impact scores compared to patients with drug-sensitive tuberculosis. Conclusions: The results suggest that patients diagnosed with MDR-TB at different stages of disease progression need urgent attention from healthcare providers.
