In the final days before the 2022 FIFA World Cup, the Mexico national football team sought more than just tactical cohesion — they aimed to arrive in Qatar in peak mental and physical condition. To support this mission, the squad partnered with Nyx-Sys, a European innovator in non-invasive athlete recovery monitoring, during their critical pre-tournament retreat in Girona, Spain.

Nyx-Sys deployed its advanced sleep and autonomic nervous system tracking platform in the team's accommodations in Girona. Rather than requiring players to wear devices or modify their routine, Nyx-Sys used discreet, contact-free sensors to gather real-time data overnight. Metrics monitored included:

• Heart Rate Variability (HRV)

• Sleep architecture (REM, deep sleep)

• Nocturnal stress response

• Respiratory efficiency

The data was analyzed daily and shared with team doctors, fitness coaches, and tactical analysts via a secure digital dashboard, allowing individualized training adjustments and recovery plans.

While the Girona camp lasted just under two weeks, the impact of integrating Nyx-Sys technology extended far beyond.

As football increasingly embraces recovery science, Mexico's experience in Girona with Nyx-Sys may serve as a model for how elite teams combine tradition, heart, and innovation on the road to the world's biggest stage.
