Announcements

In partnership with our friends at Cosmed, we are thrilled to announce the start of our webinar series!

Robert Anderson III, a Postdoctoral Research Associate at the University of North Carolina at Chapel Hill, will kick things off Friday, Nov. 6, 2026.

The webinar is open to the public, and active ACSM members are eligible for 1.0 ACSM continuing education credits (CECs).

Physical activity assessment as a vital sign has created an important opportunity to identify inactivity within routine clinical care. But identifying the problem does not necessarily tell clinicians what to prescribe next. In this session, Dr. Rob Anderson will examine how we can build on the physical activity vital sign by incorporating measures of cardiorespiratory fitness, muscular strength, and body composition to better inform individualized exercise prescription. The discussion will connect physical activity surveillance and clinical assessment with practical approaches to exercise prescription, referral, and follow-up, while considering the systems needed to make exercise a more routine component of clinical care.

Robert E. Anderson III, PhD, is a Postdoctoral Research Associate at the University of North Carolina at Chapel Hill. His research focuses on the intersection of nutrition, physical activity, and chronic disease prevention, with an emphasis on translating evidence into practical interventions across clinical and community settings. His work spans exercise and energy metabolism, Food is Medicine, and strategies for integrating physical activity and exercise into health care. Dr. Anderson also contributes to national physical activity research and practice efforts through the Physical Activity Alliance and National Physical Activity Plan and the Physical Activity Policy Research and Evaluation Network (PAPREN). He earned his PhD in Nutrition from UNC-Chapel Hill and his MS in Nutrition and Food Systems from the University of Kentucky.

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.
