VIDEO: Introducing CORE Body Temperature Monitoring 

Avoiding Heat Stress and Temperature Awareness

It is worthwhile beginning by using the CORE sensor during training and getting familiar with your temperature behavior and collecting your data. Each person is individual, knowing how your own body behaves and gaining an awareness is an invaluable first step from which you can then applying new training and cooling approaches.

With the experience in training you can start to correlate your performance against your core body temperature and begin to identify your thresholds. Learn More about avoiding heat stress >

Heat Training, Adaptation and Acclimation

It is suggested to first gain some awareness before then doing a Heat Ramp Test. This test allows you to determine your individual temperature range that is most effective for your heat training. It takes out the guessing and also ensures you are not wasting time and energy training too hold or too cold.

Heat Training is a fundamental building block for improving your performance when you get hot during sports. Usually it includes an initial intensive phase (Heat Block training) and then integration into the training plan to maintain your conditioning. The result of heat training is that you have more power available and can sustain power output longer.

Live data from the CORE sensor and historical data is an ongoing a reference to confirm that you spending enough time training in the right temperature ranges to gain the performance benefits. Learn more about heat training >

Active Cooling and Race Strategy

When race-day finally arrives, body temperature has a role to play regardless of hot or cold weather conditions. Sustained physical activity results in rising core body temperature and the aim is to keep as cool as possible so your body can divert more energy to generating power than to trying to keep cool.

During training cooling approaches can be tested to identify which which ones and which combinations work most effectively. Active cooling includes hydration, sport wear selection, cooling with water, enhancing wind flow and sweating but also race strategy.

For example a hilly course will usually mean the core temperature rises on the hills and fall on the descents. Using known (or expected) course profile information and weather conditions a race strategy can include pre-cooling and then specific cooling approaches such as check-points for hydration and, for example, to pour water over the head and body to foster cooling.
