Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Cardiovascular reserve as an integrative physiological construct: Current evidence, emerging technologies and future directions

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Cardiovascular reserve represents the integrated physiological capacity of the cardiovascular system to maintain tissue perfusion during increasing physiological stress. Although reserve has long been recognized conceptually, its direct assessment remains challenging.

Study of blood vessels reaction to local heating by imaging photoplethysmography

Научно-технический вестник информационных технологий, механики и оптики
The possibility of using a new contactless method of imaging photoplethysmography to assess thermoregulatory vasodilatation of blood vessels was studied. Perfusion reaction in a region of the outer forearm in response to local heating up to 41 ± 1 °C was

Wearable Technologies and Artificial Intelligence in Sports Medicine: A Systematic Narrative Review of Injury Prevention and Rehabilitation

Health Science Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background and Aims Wearable technologies and artificial intelligence (AI) are shifting sports medicine from episodic, subjective assessment toward continuous, data‐driven injury surveillance. This review aimed to map the main wearable sensor modalities used in injury prevention and rehabilitation, evaluate AI architectures applied to ...

TRACC‐PHYSIO: Time‐Domain Resolution‐Aligned Cross‐Correlation to Estimate PHYSIOlogical Coupling and Time Delays in Dynamic MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1605-1616, October 2026.
ABSTRACT Purpose To validate a method to assess cardiac and respiratory brain pulsations in slowly sampled dynamic MR scans. Cardiac and respiratory pulsations are key drivers of neurofluid circulation. However, resolving their temporal dynamics requires fast imaging, which is not achievable in many dynamic MR acquisitions.

Innovative Dose–Response Assessment of the Metaboreflex With Indirect Control of Intramuscular Metabolic Perturbation in Humans

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim We aimed to evaluate an innovative dose–response approach to assess the metaboreflex with control of intramuscular metabolic perturbation (concept of metaboreflex gain). We also investigated potential sex differences in the metaboreflex using this new approach.

The assessment of microcirculation in oral mucosa by means of imaging photoplethysmography

, 2019
Manipulācijas ar smaganām ir kļuvušas par standarta procedūrām zobārstniecībā rosinot nepieciešamību pēc smaganu funkcionālām izvērtēšanas metodēm. It īpaši tādēļ, ka smaganu klīniskā aina nevienmēr atspoguļo to funkcionālo stāvokli un morfoloģiskās ...
