Nix Biosensors and EF Pro Cycling team up

After initial athlete success with the Nix Hydration Biosensor, EF Pro Cycling will provide sensors to all 46 athletes, starting with Spain Training Camp attendees

May 9, 2024

We are thrilled to announce our partnership with Nix Biosensors, the leading provider of cutting-edge hydration monitoring technology.

EF Pro Cycling athletes will integrate the Nix Hydration Biosensor further into their training routines for the full season, starting with this week’s Team Camp in Sierra Nevada, Spain. With Nix’s revolutionary biosensor, EF Pro Cycling intends to customize hydration strategies for athletes on both the men’s and women’s teams, and thereby optimize performance.

The partnership highlights EF Pro Cycling's commitment to leveraging innovative technologies to gain a competitive edge in the sport. The Nix Hydration Biosensor, designed to provide real-time hydration data, will play a pivotal role in enhancing the team's understanding of their athletes' individual and unique hydration needs, enabling them to make data-driven decisions to achieve peak performance.

Dr. Kevin Sprouse, Director of Sports Science at EF Pro Cycling, expressed the team's excitement about the expanded collaboration, saying, "EF Pro Cycling places great importance on hydration to ensure peak performance. We have tested several hydration sensors in recent years, and have found Nix’s platform to be very accurate and easy to use. Our excitement about the technology has led us to now roll it out for all athletes across both the men’s and women’s teams in our continual effort to gain every edge we can for EF Pro Cycling."

The Nix Hydration Biosensor is a groundbreaking device that provides real-time hydration data, empowering athletes to optimize their performance by accurately monitoring their hydration levels. The device uses advanced sensors to quantify both fluid and electrolyte losses, providing athletes with critical decision-support data on their fluid intake needs during training and competition. Research shows that at just 2% dehydration, athletes can incur an endurance performance impairment up to 20%. By analyzing athlete data, EF Pro Cycling's medical and coaching staff can tailor hydration plans to each athlete's specific needs, ensuring they stay within their own optimal levels.

“We were delighted to hear that EF Pro Cycling learned of Nix from Dr. Sprouse,” said Meridith Cass, Nix Biosensors CEO and Founder. “Because of EF’s dedication to human performance innovation, they will be the first full team in the pro-peloton to change the way hydration strategies are crafted in professional cycling. We look forward to our technology contributing to their success.”

Tomorrow's start of the Spain training camp will mark the first group implementation of the Nix Hydration Biosensor with EF Pro Cycling. Athletes such as Alberto Bettiol, Stefan Bissegger, Rui Costa, Ben Healy, Richard Carapaz, James Shaw, Harry Sweeny, and Marijn van den Berg are among those eagerly anticipating the integration of this cutting-edge technology into their training routines. After the camp, these athletes, along with the rest of EF Pro Cycling’s roster, will utilize the Nix Hydration Biosensor during their training sessions at home, evaluating how their personal sweat metrics vary between different training intensities, locations and climates.

This collaboration between Nix Biosensors and EF Pro Cycling sets the stage for further advancements in performance optimization. As the team prepares for major competitions, including the Tour de France and Tour de France Femmes avec Zwift, the partnership promises to yield invaluable data and insights that will shape EF Pro Cycling's hydration strategies and contribute to their overall success.
