Cold Water Research Team

A Norwegian research team doing studies on extreme physiology in humans. It all starter at Norseman Xtreme Triathlon. Maintained by @jmelau

The jump from the ferry is one of the most iconic happenings in Triathlons around the world. Why do we spray all athletes with ice-cold seawater before we let them make the famous jump at Norseman? https://t.co/NhHMgWVzv9

Now, this is a good playlist! All the lectures from Norseman Science Seminar in one place. Share and enjoy!

That was all from the Norseman Research Team this evening. Hope you enjoyed it! Please do not hesitate to contact us if any questions. @jmelau #norsemanscience

The team has also compared biomarkers from Norseman to an Olympic distance triathlon. Huge differences. Olympic distance shows small changes compared to Norseman. #norsemanscience

[Cold Water Research Team @ResearchCold]

After the race, there are systematic and statistically relevant changes to several blood samples. Some of them are normally a sign of pathology. As an example - Creatine Kinase (CK) is elevated to 2450 on average (should be below 400) #norsemanscience

The Norseman research team has done a series of blood tests before race start, at the finish line and the day after. #norsemanscience

Last lecture today, is very interesting! The research team has measured biomarkers before and after the race. Medical Doctor Christoffer is presenting the study. https://t.co/fqAaCDyKIf #norsemanscience

This paper shows that Krill Oil is a good source of Choline in athletes. https://t.co/J3ZG9MdEGp @akerbiomarine @superba_krill #norsemanscience

[Cold Water Research Team @ResearchCold]

There was a large and statistically significant reduction in Choline levels in both races, with the longer races being associated with a larger decrease. The krill oil group showed significantly higher values. #norsemanscience

[Cold Water Research Team @ResearchCold]

The study gave 5 weeks pre-race of supplementation of krill oil (or placebo) to a total of 47 athletes at Norseman. Then Choline levels were measured pre-race, at the finish line and 24 hours after race. The same was done at a Olympic distance race @oslotriathlon #norsemanscience

[Cold Water Research Team @ResearchCold]

Choline is present in several processes on the human body. Coline is a precursor to acetylcholine, which stimulate muscular contractions. In long-distance races, studies have shown that Choline levels are depleted. #norsemanscience

[Cold Water Research Team @ResearchCold]

Krill oil is more than an Omega-3 supplement. An advantage of the krill oil supplement in @superba_krill is that it contains Choline. In this present study, the researchers from @akerbiomarine wanted to focus more on choline #norsemanscience

[Cold Water Research Team @ResearchCold]

@Akerbiomarine has been doing research as a part of the Norseman Research Team for a few years now, focusing on the effect of Krill Oil. Aker Biomarine is a company that develope and manufacture krill oil supplements. @superba_krill #norsemanscience

@mringster You think the water is not warm enough to get a thermophysiological effect?

[Cold Water Research Team @ResearchCold]

Results: All 5 study subjects were swimming faster with a wetsuit. No change in stroke rate. No change in average core temperature. And - no difference in core temperature with or without a wetsuit. #norsemanscience

[Cold Water Research Team @ResearchCold]

Next up is Andreas Storsve. He is a researcher and Director of A&D at @akerbiomarine He is going to talk about this study - Effect of krill oil supplements in triathletes https://t.co/J3ZG9MdEGp #norsemanscience

If you want to know more about exercise in the heat, Thijs reccomend downloading the “Beat the heat” compendium from @worldtriathlon https://t.co/A974M1cW4X

4. Stay hydrated. #norsemanscience

[Cold Water Research Team @ResearchCold]

An overwiev study performed by Thijs and the team at @radboudumc about pre-cooling is found here: https://t.co/gB7qlhF66l

3. Apply cooling strategies. Pre-cooling before the race. Per-cooling during the race. Post-cooling after the race. Studies show that if you cool yourself, you can improve your performance in the heat. #norsemanscience

2. Measure or check heat stress levels. Thijs explain the use of Wet Bulb Globe Temperature (WBGT). This measurement account for radiant heat, ambient temperature, humidity and airflow. #norsemanscience #sciencegeek #temperaturephysiology
