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.

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.

Bringing Science to the Sidelines with the Gx Sweat Patch

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

SSE #207: Dehydration and Exercise-Induced Muscle Damage: Implications for Recovery

Dehydration (>2% reduction in body mass) can result in decreased performance and delayed recovery.  Although it has not been largely studied, there is limited evidence that suggests that dehydration may exacerbate exercise induced muscle damage (EIMD) and prolong recovery.  The proposed mechanisms for the adverse effects of dehydration on EIMD include alterations in cell volume and ion flux, cell membrane disruption, impaired excitation-contraction coupling, decreased skeletal blood flow, modified red blood cell properties, and/or intensification of maladaptive signaling.

Course Objectives

  • Utilize the information presented in this SSE to create an informed opinion on the role of dehydration has on EIMD. 
  • Describe the effects of hyperthermia has on skeletal muscles and the influence hyperthermia has on EIMD.
  • Discuss the presented mechanisms of the adverse effects of dehydration on EIMD and how it negatively affects performance.

SSE #196: New ideas about hydration and its impact on the athlete's brain, heart and muscles

Dehydration is known to impair physical performance.  Additionally, dehydration and hyperthermia take a toll on other systems and organs of the body such as the cardiovascular and musculoskeletal systems and the brain.  Dehydration is influenced by environmental conditions as well as the athlete’s training status, thus influencing an athlete’s core temperature The impact of dehydration varies among individuals and depends upon factors such as training status, intensity of exercise, environmental conditions and acclimatization status.  Hydrating during training or competition by consuming fluids is the best way to prevent or alleviate the effects of dehydration on performance.
