Train and perform at your absolute best with the most accurate non-invasive wearable device for continuous core body temperature monitoring.
The sensor allows you to easily see how much your core temperature rises with effort, so you can train your body to adapt to internal and external heat. You can also design personalized cooling protocols crucial to helping you sustain your power and pace on race day. With CORE, you’ll be ready to perform at your absolute best in any conditions.
Product Description
The device uses GreenTEG’s advanced thermal sensing technology, which has been widely recognized and used by elite athletes, sports scientists, and coaches worldwide. Whether training for a competition or preparing for extreme conditions, CORE 2 helps athletes improve endurance, maintain power output, and manage heat stress efficiently.
The CORE 2 boasts a smaller and lighter design than its predecessor, making it even more comfortable and versatile. With a 48% reduction in size and a 30% weight decrease, it offers a streamlined fit, ensuring seamless integration into any training setup. The LED status indicator provides real-time feedback on device activity, charging, and battery status, so athletes can stay focused on their training without interruptions. A modular design allows easy removal from the clip, enhancing charging convenience and enabling flexible wearability options, such as integration with heart rate monitors, sports bras, or chest straps.
When combined with the CORE Mobile App, athletes gain access to detailed heat training insights and real-time thermal fitness tracking. Research-backed data confirms that heat training can significantly improve VO2 max, hemoglobin mass, and lactate threshold, all of which are critical for endurance performance. Used by world-class athletes like Olympic champion Kristian Blummenfelt and ultrarunning champion Tom Evans, CORE 2 is the go-to tool for maximizing power, endurance, and acclimatization strategies.
Whether training in extreme heat or preparing for a demanding race, CORE 2 allows athletes to track core body temperature in real time, implement cooling and pacing strategies, and efficiently acclimate to warmer climates. By staying ahead of heat-related performance declines, athletes can unlock radically improved results on race day.
Key Benefits of CORE Sensor 2
|
How does it work?The CORE 2 Thermal Sensor continuously measures an athlete’s core body temperature in real time using GreenTEG’s proprietary thermal energy transfer technology. The device is designed to be worn comfortably during exercise, providing continuous, non-invasive monitoring without the need for ingestible sensors or skin patches. It works by analyzing heat flux and skin temperature, then applies sophisticated algorithms to determine an accurate core temperature reading. By integrating with heart rate monitors and the CORE Mobile App, athletes can track their thermal load, detect early signs of overheating, and adjust intensity or cooling strategies accordingly. This data-driven approach helps athletes implement effective heat training protocols, improving VO2 max, hemoglobin mass, and endurance performance. Whether preparing for a race in hot conditions or incorporating heat acclimatization into training, CORE 2 ensures precision thermal monitoring for peak athletic performance. |
