Physical activity is a meaningful part of life, which starts before birth and lasts until death. There are many health benefits to be derived from physical activity, hence, regular engagement is recommended on a weekly basis. However, these recommendations are often not met.

Oxygen controls most metazoan metabolism, yet in mammals, tissue O levels vary widely. While extensive research has explored cellular responses to hypoxia, understanding how cells respond to physiologically high O levels remains uncertain. To address this problem, we investigated respiratory epithelia as their contact with air exposes them to some of the highest O levels in the body.

Altered neural signaling in fibromyalgia syndrome (FM) was investigated with functional magnetic resonance imaging (fMRI). We employed a novel fMRI network analysis method, Structural and Physiological Modeling (SAPM), which provides more detailed information than previous methods. The study involved brain fMRI data from participants with FM (N = 22) and a control group (HC, N = 18), acquired during a noxious stimulation paradigm.

China Football Academy, Beijing Sport University, Beijing, China.
Background: The match physical demands placed on soccer referees are intrinsically connected to their capacity to make accurate judgments, becoming the second most studied theme in associate soccer refereeing.
Objective: This study aims to review the external and internal load performed by soccer referees in high-level competitions, to identify changes in these indicators over different periods as the competition progresses, and to analyze the standards for dividing speed zones and heart rate zones.
Methods: Web of Science, PubMed, Scopus, and EBSCOhost were thoroughly searched.
The impact of a commercial lower extremity exoskeleton on metabolic load, perceived exertion, and physiological response to a challenging military relevant task: A randomized cross-over design pilot study.

CFD Research Corporation, Huntsville, AL, United States of America.
Purpose: To assess physiological metrics during the use of a commercially available bilateral active ankle exoskeleton during a challenging military-relevant task and if use of the exoskeleton during this task influences: metabolic load, physiological measures or rate of perceived exertion.
Methods: Nine healthy volunteers (5M, 4F) completed this randomized cross-over design trial, with a baseline visit and two randomized test sessions (with/without the exoskeleton). Variables included impact on time to exhaustion during walking on a treadmill at varying speeds and gradients (0-15%) at 26.
