Is lean mass quantity or quality the determinant of maximal fat oxidation capacity? The potential mediating role of cardiorespiratory fitness.
J Int Soc Sports Nutr
December 2025
University of Cadiz, ExPhy Research Group, Department of Physical Education, Puerto Real, Spain.
Background: Impaired fat oxidation is linked to cardiometabolic risk. Maximal fat oxidation rate (MFO) reflects metabolic flexibility and is influenced by lean mass, muscle strength, muscle quality - defined as the ratio of strength to mass - and cardiorespiratory fitness. The relationship between these factors and fat oxidation is not fully understood.

J Vasc Access

Clínica de Dialise Splendore, Sao Paulo, Brazil.
Introduction: Arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. Whether acute arm movement impacts arteriovenous fistula (AVF) blood flow is unknown.
Methods: In this cross-sectional analysis, we evaluated AVF blood flow using an ultrasound device at resting and after three muscle movements for proximal (elbow flexion, shoulder adduction and abduction) or distal AVF (fist extension and flexion, fingers squeeze), without and with a 2 kg load.
Physiological effects of hand grip and cold pressor tests in young Saudi adults.
J Med Life

Department of Basic Sciences, College of Science and Health Professions (COSHP), King Saud bin Abdulaziz University for Health Sciences (KSAU-HS), Jeddah, Saudi Arabia.
The risk of cardiovascular disease differs among various ethnic groups, highlighting disparities in cardiovascular health among different populations. While multiple studies from other countries have looked at changes in physiological parameters during autonomic function tests like isometric handgrip and cold pressor tests, no correlational research has been done in Saudi Arabia. This lacuna underscores the importance of examining the relationship between cardiorespiratory parameters in young Saudi Arabian individuals during these tests.

J Subst Use Addict Treat
January 2025
Rest of the World, Austin, TX, USA.
Introduction: Hispanic/Latinx (hereafter Hispanic) individuals who smoke have challenges in quitting and a disproportionate risk of smoking-related health problems when compared to the general population. The smoking inequalities among the Hispanic population are influenced by limited treatment access and chronic stress exposure (e.g.

Nutrients
January 2025
Department of Endocrinology and Diabetes, Nagoya University Graduate School of Medicine, Nagoya 466-8550, Japan.
Objective: In treating obesity, energy intake control is essential to avoid exceeding energy expenditure. However, excessive restriction of energy intake often leads to resting energy expenditure (REE) reduction, increasing hunger and making weight loss difficult. This study aimed to investigate whether providing nutritional guidance that considers energy expenditure based on the regular evaluation of REE and physical activity could effectively reduce body weight (BW) in patients with obesity.
