KSI had the awesome, unique opportunity to test two CamelBak sponsored pro-athletes over
the course of two days! The athletes were Lea Davison, a two-time Olympian Mountain Biker (2012 & 2016), and Gediminas Grinius a decorated Lithuanian trail runner. Some very fit, athletically decorated media personnel underwent testing as well. The athletes were able to undergo heat and sweat testing, where they exercised for 60-minutes total. Because it was a hot environment, the athletes were asked to collect their sweat in a specially prepared towel,and atthe end of their hour, we didwhole-body wash downs to collect samples to assess their sweat electrolyte concentrations. Whole-body wash downs are the gold standard for assessing whole-body sweat electrolyte concentration and very few labs across the country still use this technique. Many have moved over to local collection in sweat pouches, which is a great method of assessing local sweat, but not necessarily valid for whole-body calculations.
The athletes were also able to complete an anaerobic threshold test or a VO2max test where we tested their ability to ward-off an accumulation of lactate (a by-product of anaerobic metabolism) where we could extrapolate their anaerobic threshold based on continual readings, or their maximal oxygen uptake by exercising until volitional fatigue, respectively. This was a great opportunity for KSI and allowed us to use our expertise to interact with some incredible athletes.
