How to "Beat The Heat" While Competing!

While here in Doha I was surprised to learn that the Diamond League season opener is this Friday - tickets a plenty and for only $15.  I get to see many of the top track athletes in the world compete? Count me in. Only drawback is that #TeamInfinit athlete Melissa Bishop declined the invitation to compete due to the tough travel schedule associated with the event. Regardless, I'm looking forward to Friday for sure.

While scoping out the event, I saw a tweet on Heat Acclimation and Hydration by Dr. Julien Periard - a great two minute video that prompted me to look him up.  Turns out that he performs his research right here in Doha, at one of the world's leading Sports Nutrition Hospitals - Aspetar.  I reached out to Julien to see if we could meet; I wanted to learn about his research, I know there is value in this area for the athletes we support.  Julien was gracious and invited me to lunch at the hospital and then a tour of their research space.  Aspetar -Sports Medicine Hospital

Following my visit I asked Julien to share with me some of his most relevant research - I have a big list, I will dissect and share in future weeks.  He provided a document that was put together ahead of the 2016 Road Cycling Championships in Doha last October, called "Beat the Heat".  It is a great summary of the how and why to acclimate, and the role of hydration in achieving your best in hotter climates. 

Here is an excerpt from the guidance document:

"The best way to prepare for competing in the heat is to heat acclimatise. Some degree of heat acclimatization is obtained by regular training, even in cool conditions, but the most efficient method for obtaining all benefits is to train in conditions similar to the upcoming competition. The most visible adaptations of the body to repeated training in the heat include; an increased sweat rate, a decreased heart rate at a given intensity, a better retention of electrolytes, and a decreased body core temperature. These adaptations will contribute to increase performance in the heat and minimize the risk of developing heat illness."


If you are training for an endurance event that is going to be significantly hotter and more humid than you are training in, we would recommend you have a read of the entire document.

Thanks to Julien Periard for sharing his wisdom.  I often find some of the best researchers come from an athletic background - they use their academics and their own bodies as real-life science experiments to drive a further understanding of how and why things work.  Here you can see Julien pushing himself in the desert at The 2016 Al Adaid Desert Challenge

  1. Darcy,
    Thanks for sharing your story. I haven't met Julien but I've followed his research, presentations and publications for a few years now. He definitely has not only a wealth of knowledge on the subject, he also has an effective to present it. The icing on the cake for me too was watching him "walk the talk" in the Aldaid Desert Challenge. Hope to meet him someday as well.

  2. Agreed David. Keep following his twitter - doing a 10 day acclimation right now in their chambers (@DrJPeriard). He just finished Day 7 where he held 65% VO2Max heart rate over 90 min while getting to 4% dehydration. Will be good to see the power impact while their systems kept his heart rate constant.
