Core 2 Thermal Sensor

CORE 2 monitors your thermal data in real time for better performance. Safely and effectively facilitate heat training to increase your haemoglobin mass and VO2 max, or monitor your data on race day so you can cool down and dose your efforts accordingly.With CORE, you can safely perform heat training that has been proven in controlled laboratory studies to increase haemoglobin mass, VO2 max, lactate threshold, power output and blood plasma, and stay cooler for longer thanks to heat adaptation, allowing you to boost your race day performance regardless of temperatures. CORE also allows you to monitor your thermal vitals in real time to adjust your pace and cool down accordingly.

Heat training load

Your heat training load is the daily value (on a scale from 0 to 10) for the time spent in the heat training zone (zone 3). Optimal heat training involves 2 to 3 sessions per week with a duration of 45 to 60 minutes per session in the heat training zone. Consecutive days of high heat training load will increase your heat adaptation score.

Heat Adaptation Value

Under the right conditions, the human body has an amazing ability to adapt. The heat adaptation score uses a scientifically based formula to calculate how well you have adapted to heat on a scale from 0 to 100 %. Use the heat zones as a guide for your training to achieve high daily heat training loads that will increase your heat adaptation score over time.

Core body temperature and skin temperature

Core body temperature is the temperature near the internal organs in the torso. The core temperature rises when we are physically active and if it gets too high, performance suffers. Skin temperature varies greatly depending on environmental conditions. Although skin temperature helps your body to regulate core temperature, there is often little correlation between the two. Both values are used to calculate your heat stress index.
