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.

Course Objectives

  • Define the different types of sweat glands and which is most relevant to sweat biomarker analysis. 
  • Identify the electrolytes, trace minerals and vitamins, metabolites, nitrogenous waste, stress and immune markers found in sweat and discuss their evidence as a biomarker. 
  • Describe the roles of wearable technologies in sweat biomarker analysis and where additional research is needed.

SSE #210: Hydration and team sport cognitive function, technical skill and physical performance

Team sport athletes are at risk of training and competing in a hypohydrated state when fluid losses are large and/or there are challenges with fluid availability or opportunity to drink. Technical skill and cognitive function are essential to team sport athlete performance and may be impaired with hypohydration, especially when combined with heat stress. The mechanism of cognitive impairment with hypohydration is not fully understood. Decrements in cognitive function, skill and physical performance in team sports are more likely to occur when hypohydration levels are > 2% body mass loss, but there is significant inter-individual variability in the effect of hypohydration on team sport performance.

SSE #210: Hydration and team sport cognitive function, technical skill and physical performance

Course Objectives

  • Utilize data presented in the SSE to identify the sports and individuals that may be at greatest risk for hypohydration during team sport practices and games.
  • Describe the risk factors for hypohydration that, when met, may impact technical skills and cognitive function during team sport play. 
  • Discuss practical strategies to allow athletes access to fluid and adequate opportunities to drink during team sport practices and games.
