Research Awards or Scholarships

Marsh Center Student Research Award

Awarded annually by the Department of Kinesiology at the University of Wisconsin – Madison, this competitive award recognizes outstanding research presentations by two student members of the Psychobiology and Behavior Special Interest Group of the American College of Sports Medicine.

Awardees will receive a certificate of achievement, a $500 award, and recognition at the ACSM Annual Meeting. Award winners will also be expected to present the highlights of their research at the special interest group meeting.

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.
