You’d be surprised at the amount of data recorded during a round of the Monster Energy Supercross Series. While we know about the myriad of sensors scattered around the factory machinery ridden by the sport’s top stars, plenty of riders are strapping on heart rate monitors and charting the numbers from their body experienced by their bodies in a non-stop main event. A band containing a sensor is worn on the chest, beneath the jersey, and a dashboard style watch is kept somewhere close to display what’s happening in real-time. Once the moto is over, riders and their personal trainers will pour over the information to look for peak numbers or telling signs to watch for in the future. What trainers gather from the heart rate monitor sets the tone for each weekly training program, as they help reveal if the athlete is getting run down or hitting their stride as the season wears on. Like anything, there are plenty of options to choose from when looking to purchase a system, but most moto trainers recommend Polar or Garmin goods. We recently spent a few moments with Pablo Toribio, former cyclist and trainer to Yoshimura Suzuki’s James Stewart, learning more about the use of the high-tech systems.
