Active Voice | With Resistance Training, Load is Only Half the Story

For decades, one question has dominated resistance-training research: How much weight should we lift? Many studies have compared heavy and light loads to identify the optimal stimulus for maximizing strength and muscle hypertrophy. These investigations have shaped coaching practice, informed resistance-training guidelines, and fueled one of the longest-running debates in exercise science. Yet this question […]

Active Voice | Rethinking Cardiac Aging: Resistance Training is More Than a Muscle Intervention

For decades, we have told our patients, students, and colleagues that aerobic exercise is the cornerstone of cardiovascular health. Walking, running, cycling, and other endurance-based activities have long been viewed as the primary exercise strategies for protecting the aging heart. Resistance training, meanwhile, has largely been prescribed for different reasons—to increase muscle mass, improve strength, […]

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.
