Physically demanding occupations (PDO) require high levels of energy expenditure and technical skill to complete day-to-day tasks and training. Workers in PDO are at a greater risk for heat strain/illness compared to other occupations worldwide. While research for nutrition requirements for PDO is somewhat limited, there is evidence that the current daily caloric intake habits of some workers may only account for half of their daily energy expenditure. The authors review the physiological and metabolic demands of the tasks encompassed in PDO and the current guidelines for proper hydration and nutrition for these various professions.

Athletes’ use of supplements is highly prevalent across sport and competitive levels. High prevalence is combined with indiscriminate use. This remains a concern in sport as it can lead to negative health effects and the risk of committing an anti-doping rule violation. Consequences of committing an anti-doping rule violation through supplement use are significant for competitive athletes due to the principle of strict liability. The principle of strict liability interacts with a growing and professionally marketed industry that is poorly regulated. Consequently, competitive athletes can find themselves in a vulnerable and risky position when it comes to consuming supplements. Dr Susan Backhouse discusses adopting a behavioral approach and adherence to RMSUG to help identify what needs to change to protect athletes from unintentionally doping through indiscriminate supplement use.

Daily hydration management for a youth athlete extends beyond just sport performance to also facilitating academic achievement and overall health. Establishing sensible hydration behaviors as a youth athlete can be instrumental in underpinning healthy hydration habits as an adult that enable wellness and help to maintain long-term health. As youth develop and advance through sport, they need to develop personal initiative and autonomy to make healthy and ethical decisions about their involvement in sport, including managing their own hydration needs and strategies. Dr Michael Bergeron discusses contemporary approaches utilizing multi-domain, complex systems, and state-of-the-art tools and methods instrumental in fully recognizing the wide-ranging role and contribution of hydration to youth athletes’ health and sustainable sport participation and performance.

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.

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.
