Optimal Nutrition for Youth Athletes

Episode 19

Join us for an essential episode of The Healthy Youth Sports Podcast as we explore “Optimal Nutrition for Youth Athletes” with Dr. Jennifer Sacheck, a renowned expert in nutrition and exercise science from The George Washington University. Dr. Sacheck shares her insights on how young athletes can meet the demands of growth, development, and increased physical activity through proper nutrition.

In this episode, we cover:

  1. A high-level background on nutrition for youth athletes.
  2. Caloric (energy) needs to support both growth and physical activity.
  3. What to eat: an in-depth look at macronutrients—carbohydrates, protein, and fat—and their food sources.
  4. When to eat: strategies for fueling pre-exercise, during exercise, and post-exercise/recovery.

Whether you’re a parent, coach, or young athlete, this episode provides valuable guidance on optimizing nutrition to enhance performance and support healthy development. Tune in to learn how to fuel young athletes for success both on and off the field.

Guest: Jennifer Sacheck, PhD, MS, FACSM, Sanofi Professor of Prevention and Wellness; Chair | Department of Exercise and Nutrition Sciences; Director, PhD Program in Exercise Physiology & Applied Nutrition; Milken Institute School of Public Health; The George Washington University

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.
