While laboratory-based testing using blood or urine samples is considered to be of higher quality, they have traditionally been the most difficult to implement in a team setting.

Because of this many athletes and teams opt to use easier testing methods, despite limitations of accuracy or reliability. These methods include subjective urine color charts, weigh-ins and sweat rate, and relative thirst levels. Given the importance of hydration and fueling, as well as the unique challenges that come along with the variety of options, what exactly are athletes and teams doing behind the scenes to keep tabs on hydration?

PROS: weighing in pre- and post-activity offers a very good indicator of sweat loss and hydration status, and this can be done daily throughout the week. When paired with sweat rate that also takes into consideration fluid intake and urine loss, athletes can take action on hydration amounts over time for replenishment.

Sweat rate can also be highly individual, and this method also requires the collection and handling of urine and bodily fluids which is messy and time consuming. These are considered a close proxy to hydration status as osmolality testing focuses on determining the concentration of a solution such as plasma or urine.

This is a method that is performed least often and has the least amount of repeatability in a team setting as well. PROS: can be intertwined with pre- and post-activity weigh-ins and provides insight into total body water volume. This can be done on a near daily basis and performed throughout the day as well.

CONS: the equipment can be very expensive and require dedicated space and access that can be difficult to accommodate.

Bio-Impedance also possesses a relatively high error variance for assessing total body water, even when adhering to strict protocols. As many athletes and staff know, it can be quite difficult to adhere to strict measurement protocols in a busy team setting. PROS: osmolality of saliva appears to correlate well with hydration status and can be administered on a near daily basis via a minimally invasive process.

Saliva testing can sometimes be used as a proxy for subjective thirst levels, which is obviously an easily implemented method. Additionally, the timing of the saliva testing and any hydration intake such as a 10 second mouth rinse with water can significantly skew results and give a false indicator of hydration.

PROS: an easily administered assessment for athletes to use each time they urinate during the day, every day.

There are many methods for determining hydration status, including monitoring body mass changes, measuring sweat, various blood markers and analysis of urine.
