As a business, Gatorade believes sports performance is driven from the inside. 
Its goal is to educate athletes that the fuel they put in their bodies helps 
improve performance and win from within.

In 2016, the world's number one sports drink started a five-year partnership 
with one of the world's most successful rugby teams to become the official 
hydration partner of the All Blacks, helping the boys to perform at their peak. 
The partnership also provides access to the Gatorade Sports Science Institute 
(GSSI), the research and development arm of Gatorade.

Gatorade has a 50-year history of studying the best athletes in the world. With 
a commitment to science-based innovation, in the lab and on the field, no one 
knows fuelling needs better. 

Founded in 1985, the Gatorade Sports Science Institute (GSSI) is committed to 
helping athletes optimise their health and performance through research and 
education in hydration and nutrition science. GSSI scientists study the effects 
of nutrition on the human body before, during and after exercise. 

The Gatorade Sports Science Institute (GSSI) Sweat Test is a two-part physical 
assessment based on athletes' fluid balance and sweat sodium. Athletes lose 
water and electrolytes as a consequence of thermoregulatory sweating during 
training and competition.

In some situations, dehydration can be enough to cause excessive water or 
electrolyte imbalances and impair performance, so sweat tests can help identify 
individual fluid and electrolyte needs and improve hydration strategies.

For the boys in black, "the main thing we're looking at is sodium loss over a 
period of time, so we'll be looking at how we can help players replace what 
they've used while they've been playing, and as a result in recovery as well," 
says Katrina Darry, All Blacks Dietitian. 

It is well established that dehydration rates and electrolyte concentrations 
can vary widely among individuals. Therefore, it is recommended that fluid 
replacement strategies are personalised to the individual as well as tailored 
to the specific conditions of training/competition.

"Everyone is going to sweat differently. Some people are going to run hotter 
than others, body weight and fitness level can factor into that, how much lean 
muscle mass, all these things can change the way everyone sweats and what rate 
they sweat. So everyone (including the All Blacks) is on an individualised plan 
that helps them feel at their best for game day," says Logan Posthumus, GSSI 
Advisor.

Having access to the science and knowledge provided by GSSI continues to help 
the players be at their peak performance on the world stage. Gatorade contains 
fluids and electrolytes to help replace what is lost in sweat, rehydrating and 
replenishing athletes after performance.
