The modified Borg cycle strength test (mBCST): Feasibility and physiological response in people with COPD and healthy older adults

Experimental Physiology, EarlyView.
Abstract Accurate prescription of supramaximal exercise requires exercise tests covering the intensity domain between maximal aerobic and peak power output. All‐out tests are commonly used for this objective but are considered challenging for people with chronic obstructive pulmonary disease (COPD) due to the extreme physiological demand.

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

Experimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

Experimental Physiology, EarlyView.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

A new method for bedside determination of effective lung volume and functional residual capacity

Experimental Physiology, EarlyView.
Abstract Established methods of measuring functional residual capacity (FRC) involve sophisticated equipment and elaborate procedures. Here we present a new method based on CO2 rebreathing that has a simple fast procedure and only requires end‐tidal CO2 monitoring. Ten healthy subjects with diverse anthropometric and respiratory parameters were studied

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Akut pulmoner embolide diffüzyon kapasitesi (DLco) ve pulmoner emboli tedavisinin DLco üzerine etkisi

, 2021
Pulmonary embolism; in spite of developments in the diagnostic methods, still has high morbidity and mortality ratios because of the delays in the treatment. Carbonmonoxide diffusion capacity of the lungs (DLCO), as a cheap and repeatable test without complications, is used for diagnosis and follow-up of progression of the paranchimal diseases of the ...

Pulmonary Obstruction and Age, Not Activity, Associate With Muscle Oxidative Impairment in Smokers With and Without COPD

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Low muscle oxidative capacity is an extrapulmonary manifestation of chronic obstructive pulmonary disease (COPD) with unclear aetiology. We sought to characterize locomotor muscle oxidative capacity in never smokers and ever smokers with and without COPD and determine clinical and behavioural features associated with low muscle ...
