Active Voice | Midlife Physical Activity and Heart Failure Prevention

Heart failure does not develop overnight. Rather, it is a disease that can progress over several decades; long before symptoms are apparent to the individual or their physician. During later, clinical stages of heart failure, it can be very difficult for the individual to be physically active at any level. While clinical heart failure is […]

Hot Topic | Physiological Assessments Using Muscle Near-Infrared Spectroscopy (mNIRS)

What is muscle near-infrared spectroscopy (mNIRS)? Muscle near-infrared spectroscopy (mNIRS) is a non-invasive technique that can be used to measure the changes in blood volume and oxygenation responses within the smaller diameter blood vessels in skeletal muscle. This is possible because near infrared light (~700-900 nm) emitted into biological tissues can help determine the oxygenation […]

GSSI Pre-Conference

The Physiology of Hydration: More Than Water Alone

This session explores the physiology of hydration through an integrated lens—examining how carbohydrate, sodium, flavor, and fluid interact to influence intake, absorption, retention, and performance. We’ll review current research on fluid balance, osmotic drivers, and palatability, highlighting mechanisms that underpin voluntary intake and thermoregulation. Attendees will gain insight into individualized strategies, including sweat profiling and timing approaches, to optimize euhydration and mitigate performance decrements associated with >2% body-mass loss. Practical applications will be linked to laboratory- and field-based research, ensuring translation from bench to field. This pre-conference equips you with evidence-based tools to support athlete hydration across diverse environments and sporting contexts.
