Bringing the Heat

CORE is the first and only core temperature sensor that provides continuous and accurate measurements.

Core_2_Thermal_Sensor

CORE measures what really matters

Just like an engine, your body loses about 80% of the energy it uses as heat. CORE measures and records your thermal vitals, so you can safely and effectively optimize your body's thermoregulatory system.

    Heat load

    Heat strain describes the physiological processes that help the body cool down. The harder the body works to cool itself, the greater the strain and the greater the impact on performance. CORE’s Heat Strain Index (HSI) quantifies this strain in real time through an algorithmic combination of core temperature and skin temperature.

  • Core_2_Thermal_Sensor

    Heat zones

    Your Heat Strain Index can fall into 1 of 4 Heat Zones. The Heat Training Zone (Zone 3) is the zone that produces physiological adaptations that improve performance. The time you spend in each zone is tracked in the CORE app.

  • Core_2_Thermal_Sensor

    Heat training load

    Your Heat Training Load is the daily value (on a scale of 0-10) of the time you spend in the heat training zone (Zone 3). Optimal heat training consists of 2-3 sessions per week, with 45-60 minutes per session in the heat training zone.

    Heat Adaptation Score

    Under the right conditions, the human body has an impressive ability to adapt. The Heat Adaptation Score uses a research-based formula to calculate how well your body has adapted to the heat, on a scale of 0-100%.

    Core and Skin Temperature

    Core body temperature is the temperature near the internal organs in the torso. Core temperature rises during physical activity, and if it becomes too high, it will negatively affect performance. Skin temperature varies greatly depending on environmental conditions.

  • Train Hot

    CORE allows you to safely engage in heat acclimationβ€”a form of exercise shown in controlled laboratory studies to increase hemoglobin mass, VOβ‚‚max, lactate threshold, power output, and blood plasma volume .

  • Race Cool

    Heat training makes your body more resistant to heat, keeping you cooler and performing at a higher level for longer – regardless of the temperature on race day . CORE also lets you monitor your thermal values ​​in real time, so you can intelligently adjust your pacing and cooling accordingly.
