- CORE, maker of the only non-invasive core body temperature monitor, launched its most significant app update yet to overcome adverse effects of extreme heat in sports
- CORE is used by over 65% of the UCI World Tour, defending Olympic gold medalist triathlete Kristian Blummenfelt, and many more olympians, including, Remco Evenepoel, Fintan McCarthy and Ross Corrigan

CORE, the sole creator of non-invasive core body temperature monitors, just launched its groundbreaking Heat Adaptation Score ahead of the Olympic Games. This new feature provides athletes with real-time insights into how their bodies are adjusting to thermal stress as they prepare for increasingly hot competition settings. The new metric, now available to all users of the CORE body temperature sensor, compiles the results of the Heat Strain Index and Heat Zones launched June 2024 to make tracking progress easier, offer guidance to refine training methods for better heat adaptation, and inform pacing in hot events.

The new feature comes as concerns are rising over the predicted adverse effects of heat at the Tour de France and Paris Olympic Games this summer. According to the latest report from BASIS, one of the key recommendations to help mitigate the disruptive and potentially dangerous effects of extreme heat at both local and global competitions includes the “deployment of enhanced technology to monitor heat and body temperatures.”
Previously, tracking heat adaptation progress required the expertise of sports scientists or coaches. CORE has changed this with its innovative Heat Adaptation Score feature in their mobile app, allowing athletes to monitor their thermal stress adaptation independently. This cutting-edge tool uses an evidence-based formula developed through extensive scientific research in Zurich, offering athletes a precise measure of their heat adaptation to optimise training effectively.
CORE is known for its non-invasive core body temperature monitoring technology, which is used by over 65% of the UCI World Tour. Notably, it is also used by many athletes competing in the 2024 Olympics, including Kristian Blummenfelt, the defending Olympic gold medalist in triathlon and 2021 Ironman World Champion, Maya Kingma, an Dutch triathlete, as well as Irish rowers Fintan McCarthy and Ross Corrigan, cyclists, such as Remco Evenepoel, and track athletes, like Lily Williams. This technology has revolutionised how athletes across various disciplines gear up for peak performance.



CORE Physiologist, Puck Alkemade PhD, has been intrinsic in the development of the Heat Adaptation Score. She commented “Most athletes do not have a team of sports scientists on staff. So we want to make it easier for athletes to learn and use thermal data like the pros and for coaches to give more specific direction.”
VP and Global Head of CORE, Ross McGraw, says: “We’re thrilled to make the thermal data and insights used by elite athletes more accessible to endurance competitors. With heat significantly impacting performance and global temperatures rising, it’s crucial to extend CORE technology to more athletes. This update will transform how athletes comprehend, relate to, and adapt to thermal stress.”
Arne Dedrie of Human Powered Health Cycling, partners of CORE, says: “Hot conditions increase the physiological strain on the body and can result in a marked decrease in performance. The CORE sensor is able to quantify this source of fatigue and guide us during training interventions designed to optimise our athletes’ thermoregulatory capacity. ”
The CORE app is free to download for Android from Google Play and iOS from the Apple App Store, and is available in English, Spanish, French, German and Japanese. Another update to in-app insights is planned for mid-summer.
