Introduction: Lung diffusion capacity of carbon monoxide (DLCO) provides a measure of gas transfer in the lungs, which increase in relation to exercise and decrease in the presence of lung interstitial disease. The aim of this study is to evaluate the changes in lung diffusion after anaerobic and aerobic exercise in a cycle ergometer. Material and...
Pulse arrival times (PAT) are time intervals between the electrocardiogram (ECG) and an arterial pulse wave (APW) widely used to obtain cuffless blood pressure. Although some distal APW’s can be easily measured using, for example, a photoplethysmography (PPG) sensor on a finger, proximal APW’s, such as the one of the carotid in the neck, are much m...
Introduction: The genetic disorder causing Down syndrome (DS) affects the cardiorespiratory and hemodynamic parameters. When exercising, sufficient blood flow is necessary for active muscles. Cardiac output (Q) must be proportional to the peripheral requirements. In case the stroke volume (SV) is lower, the heart rate (HR) will increase further in...
Universal exercise recommendations for adults neglect individual preferences, changing constraints, and their potential impact on associated health benefits. A recent proposal suggests replacing the standardized World Health Organisation (WHO) exercise recommendations for healthy adults by co-designed interventions where individuals participate act...

Magnesium (Mg) is an important intracellular ion with electrophysiological properties. It is essential for optimal metabolic cell function. Serum Mg is a poor predictor of body stores, as less than 1 % of total body Mg is found in serum. Ionized Mg assessment, the active portion of Mg, may be a more useful indicator than total serum Mg assessment....
Circulating progenitor cells (CPC) are bone marrow-derived cells that are mobilized into the circulation. While exercise is a powerful mediator of hematopoiesis, CPC levels increase, and reports of their activation after different types of exercise are contradictory. Moreover, few studies have compared the possible effects of different training pro...
