The CoreCooling products have been tested:
- In a test at 3in1Sports training centre
- In real-world usage by triathletes in preparation and racing the 2024 Ironman World Championships triathlon long distance in Kona, Hawaii.
Test at 3in1Sports training centre
3 identical training sessions have been completed:
- Without body cooling products
- With the Tri-excellence CoreCooling products
- With traditional body cooling (cold water and ice).
The test subjects followed a 1h45min endurance training protocol.
Many studies have been done where it was proven that cooling during sports has a positive effect on the heart-rate, core temperature and perceived exertion of (endurance) athletes. At 3in1Sports training centre this has been confirmed. Very clear differences can be seen between both ear and core temperatures, heart rate and perceived training intensity (Borg scores). In the first 30-40 minutes the differences are present but not very large, but after that the differences are very significant.
The conclusion is that cooling during sports in warm conditions makes absolute sense, especially after 30-40 minutes the positive effect of body cooling becomes very clear.
Next to that, also trainings with cooling during exercise were applied. In this way the effects of traditional cooling (cold water & ice) and cooling with Tri-excellence CoreCooling were compared with each-other.
Below are some of the graphs that show the test-results. More info can be found on the tri-excellence.com website.
The conclusion of this study is clear:
1) Tri-excellence CoreCooling provides a much lower core temperature during this heat-training (between 0.5 to 2.0 °C (0.9 - 3.6°F)) compared to traditional cold water and ice.
2) the perceived exertion levels are much lower (20-30%) difference when Tri-excellence CoreCooling is applied, compared to traditional cold water and ice.
Real-time experiences
The findings have been confirmed by triathlon elite spotters who have been using CoreCooling prior to their Ironman World Championship long distance Kona, Hawaii and also during the race itself:
Arnaud Guilloux (Pro elite)
I used the CoreCooling with ice in the pockets and I noticed that my core temperature stayed under 38.0°C (100.4°F). In the days before, when I did the same training in the same circumstance, also at the same power pace, my core temperature was 38.6°C (101.5°F) degrees on average. So while using CoreCooling I measured that my core temperature stayed more than 0.6°C (1.1°F) lower, this is a huge difference!
Olaf van den Berg (age-group 30-34)
My Kona Race experience: I used the CoreCooling base-layer and head-band. It was really nice and effective. It helped me extremely well, especially during the run.
Colin Cook (age-group 40-44)
Especially in the 2nd part of the run, I felt way better than I ever have. The last 10 miles on the marathon are normally pure agony and miserable, but I felt much, much better than ever before and that was because I was a lot cooler. Having as much experience on that race, the way I felt in the second half of the run is a huge game-changer.
This was my 7th Kona World Champion race. I managed to get 16 minutes off my Personal Best, including 7 minutes off my Personal Best on the run.
Kacper Stępniak (Pro elite)
I really needed the cooling. I came from the bike 'cooked' and after 5 KM running I felt like I would not be able to finish the race. So I switched to surviving-mode more than racing and I started to fill the pockets of the base-layer with ice. After 5 KM more, when I reached Queen-K, I felt my body cooled down a lot and I could start to race again!
Clément Mignon (Pro elite)
My training was at race pace, like the trainings I did during earlier days at Kona. What I feel is that with the CoreCooling I feel much better, I felt the positive effect directly. Also my heart rate was 10 bpm lower. The arm-sleeves and head-band surprised me the most, fit good and feel very nice.
Tristan Olij (Pro elite)
I could use the head-band and arm-sleeves during the race. Putting the ice in the pockets worked very well, especially since I took ice-cubes in a cup from aid stations and then put the ice-cubes in the pockets one by one during running.
The good thing about the CoreCooling is that I did not notice it during the race. I mean, you just do not notice any hinder. Just the coolness.
The CoreCooling just works, easy as that. I will implement it in my cooling strategy for races. And also use it during my indoor trainings in winter, it will help me to train with more quality and to recover faster.
Lars van der Meulen (Age group 18-24)
Now at Kona, I have done several running sessions as preparation for the IM World Championship race. I have been running (in Energy Lab) at sub3 pace, 4.13 min/km on several days and I saw my Core temperature increase to 39.6 39.6°C (103.3°F) with an average heart-rate of 173 bpm. The distances I ran varied from 9 to 12 KM.
When I did the same training, but now for 16 KM, while using Core Cooling (arm-sleeves, head-band and base-layer, using cold water and ice), my Core temperature did not go higher then 38.5°C (101.3°F)and my average heart-rate was 155. So the CoreCooling gives me a 18 bpm lower heart-rate and 1.1 °C (2.0°F) lower core temperature!
Menno Koolhaas (Pro elite)
In preparation for the IM Kona World Championships 2024 I used the base-layer under my swim-skin during training in The Netherlands. Basically I did not feel I was wearing it and I could swim freely. I found the head-band fine as well, it is very easy to adjust it to my head size exactly.
Now I am at Kona and I used the CoreCooling head-band and arm-sleeves. I used it with ice and that works great. It gave me the feeling it kept me 'cool' and also my core temperature remained low.
Tri-excellence CoreCooling:
Keep your core temperature lower, improve endurance, and recover faster so you can train harder and race stronger. Make cooling part of your routine, in both warm and moderate conditions, and reach new levels of performance!
