SSE 244: The Fluid Replacement Process: Principles of Beverage Formulation for Athletes

Substantial volumes of fluid can be lost during intense or prolonged exercise as a consequence of thermoregulatory sweating. In these situations, athletes need to drink during and after exercise to replace fluids lost to avoid potential negative effects of dehydration. Fluid replacement is a multi-step process involving a number of physiological systems including fluid intake, fluid delivery to the bloodstream, distribution within the body fluid compartments, and whole-body fluid retention. Adequate fluid replacement is influenced by beverage composition, as certain ingredients can facilitate or hinder one or more steps in the rehydration process. Dr Lindsay Baker reviews the scientific principles of fluid replacement and role of beverage formulation on the rehydration process for athletes.

SSE 237: Hydration in Physically Active Women

A significant amount of research has been conducted to understand body water regulation and the effects of hypohydration on thermoregulation, cardiovascular function, and performance during exercise in heat. However, women have been underrepresented in hydration research, accounting for less than ~30% of subjects tested in recent studies. Women have lower whole body sweating rate (WBSR) and sweat sodium concentrations as a population than men, but in most environments these differences are attributed to lower absolute workloads. Dr Lindsay Baker reviews the state of the literature, the impact of the menstrual cycle on hydration and how hypohydration (≥ 2% body mass loss) can adversely affect athletic performance in women.

SSE 226: Sweat Biomarkers for Sports Science Applications

There has been considerable interest recently in the concept of sweat biomarkers, which is generally defined as the use of sweat as a non-invasive alternative to blood analysis to provide insights into human physiology, health, and performance. Despite recent technological advances in wearable devices the application of sweat diagnostics in sports science has been limited to date. This course will discuss the challenges of utilizing sweat biomarkers and wearable technologies as well as where future work is needed.
