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.

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.

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.

Session 2 from the 2021 ACSM/GSSI Go the Distance Summer Symposium features Lindsay Baker PhD, FACSM and Anthony Wolfe MS of GSSI. Due to the high variability of sweat fluid losses and sweat sodium concentration, it is important for athletes to develop hydration plans based upon individual needs to support performance safety during exercise. Lindsay and Anthony discuss the research and validation behind the development of the Gx Sweat Patch, as well as the technology utilized to bring sweat testing and application of the sweat data to the consumer.
Course Objectives
Discuss the variability of sweat sodium concentration and sweat fluid losses in athletes based upon published sweat normative data
Describe the validity of the Gx sweat patch and how it compares to standardized sweat testing methods
Utilize the data collected from the Gx sweat patch to develop customized hydration plans for individual athletes
