Did you know that in 2017, a University of Texas football coach created a urine-based “Longhorn Football Hydration Chart,” which labeled players with yellow urine as “selfish teammates” and those with brown urine as “bad guys.” This “hydration shaming” practice has permeated high school sports, thereby encouraging a sporting culture which equates superior performance with superior hydration. Dehydration is still a major problem in sports.
By now, most coaches and athletes are familiar with the dangers of dehydration, especially during hot practices. However, it’s also important to understand the dangers of overhydration – a medical condition known as exercise-associated hyponatremia. Hyponatremia is caused by drinking too much water or sports drinks, which dilutes blood salt levels below the normal range. Any sudden drop in blood salt levels, from drinking more than the body can excrete, can cause all cells in the body to swell. Brain swelling from hyponatremia can cause headaches and vomiting, while muscle cell swelling can trigger whole-body muscle cramping.
With our combination of sensors and deep-learning algorithms it is possible to measure overhydration and prevent the dangers that overhydration can cause. It also prevents the dangers of dehydration by sending out a signal to the sporter at the moment that he or she should drink according tot he course of the impedance and the effort during the match or training.
Research shows that this danger mainly occurs in endurance sports such as cycling, running, skating and swimming. Endurance sport is a collective term for long-term sports. This means longer than, and in one piece, half to a few hours of exercise. What you eat and drink has a major impact on your performance as an endurance athlete. In general it is very important to pay attention to the times when you eat or drink. Endurance athletes often have difficulty with this. BodyGraph wants to respond to this by developing a product that the athlete can support in this.
