What is a clinical exercise physiologist?

Clinical exercise physiologists are rising health care professionals who have a minimum of a bachelor’s degree in Exercise Science and 1,200 hours of practical experience OR a master’s degree in Clinical Exercise Physiology and 600 hours of practical experience. The ACSM Clinical Exercise Physiologist (ACSM-CEP®) certification enables these professionals to use evidence-based practice to design, implement and supervise exercise programming for those with chronic diseases, conditions or physical limitations.

ACSM-CEPs perform many critical tasks, including:

  • Conduct exercise assessments (including cardiac stress testing) and training.
  • Identify risk factors.
  • Use behavioral health strategies to help patients make lifestyle changes to improve their physical wellbeing.
  • Perform clinical assessments.
  • Perform tasks related to education and behavior change.
  • Administer exercise programming.

Clinical exercise physiologists work in a number of settings, including hospitals/clinics, rehabilitation facilities, physician’s offices, research-based clinics, universities or corporate settings.

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.
