2 Thermal Sensor for Body Temperature Monitoring

CORE 2 Thermal Sensor for Body Temperature Monitoring

The CORE 2 Thermal Sensor provides real-time body temperature monitoring to support performance and training. It enables athletes to train safely and effectively in the heat, helping to increase haemoglobin mass and VO2 max. On race day, it offers valuable thermal data to inform cooling strategies and pacing, allowing athletes to manage their effort with precision.

The CORE 2 sensor attaches comfortably to a heart rate monitor strap or armband. Its Swiss-made heat flux sensor not only detects changes in skin temperature but also measures the flow of heat into or out of the body, providing a deeper understanding of thermal strain.

Heat Strain Index
Heat strain refers to the body’s physiological response to cooling itself. The greater the effort required to regulate temperature, the higher the strain and the more significant the impact on performance. CORE’s Heat Strain Index (HSI) quantifies this in real time, using a proprietary algorithm that combines core and skin temperature data to deliver a clear measure of thermal load.

Heat Zones
The Heat Strain Index is divided into four distinct heat zones. Zone 3, known as the heat training zone, is where beneficial physiological adaptations occur that can lead to improved performance. Time spent in each zone is automatically tracked and displayed in the CORE app, providing valuable insights for training and race-day pacing.

Heat Training Load
Heat Training Load is a daily score, rated from 0 to 10, reflecting the amount of time spent in the heat training zone (Zone 3). For effective heat training, the optimal approach involves two to three sessions per week, each lasting 45 to 60 minutes within Zone 3. Consecutive days with a high Heat Training Load will gradually increase the Heat Adaptation Score, indicating improved heat resilience and conditioning.

Heat Adaptation Score
Given the right conditions, the human body has a remarkable ability to adapt. The Heat Adaptation Score is calculated using a research-based formula to indicate how well an individual is adapted to heat, presented as a percentage from 0 to 100. By targeting high daily Heat Training Loads through structured training in the appropriate Heat Zones, this score can be progressively increased over time.

Core and Skin Temperatures
Core body temperature refers to the temperature around the internal organs within the torso. It increases during exercise and, if it rises too high, can negatively affect performance. Skin temperature, on the other hand, fluctuates significantly based on environmental conditions. While it plays a role in regulating core temperature, there is often limited correlation between the two. Both core and skin temperatures are used to determine the Heat Strain Index.
