The Importance of Cardiorespiratory Fitness, A 10-Year Update

This year marks the 10-year anniversary of the American Heart Association’s (AHA) policy statement “The Importance of Cardiorespiratory Fitness in the United States: The Need for a National Registry.” In my teaching and lecturing, I have often commented that the field of exercise physiology is a very young area of science. Much of the foundations […]

Dietary Nitrate and Women’s Athletic Performance: A Call for Further Research

Nitrate supplementation has consistently been shown to benefit exercise performance due to its capacity to increase nitric oxide (NO), a signaling molecule that plays an important role in skeletal muscle function during exercise. Once ingested, nitrate is converted to nitrite via anaerobic bacteria in the oral cavity and nitrite is converted to NO especially under conditions […]

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.
