This short article is for individuals who will be attending our training camp in Thanyapura, Thailand, or maybe you have a race coming up in a hot and humid climate (such as the IRONMAN World Championships in Kona or Busso).
The heat, as we all know, is a hot topic in long-distance triathlon. Because our camp in Thailand will be hot and humid, we will need to adapt to the heat before partaking in these hot-weather activities. Heat acclimatisation may appear to be a complicated procedure, but it is just the process by which your body adapts to heat stress. High temperatures and humidity (which can raise your heart rate and make your workout feel much tougher) can be mitigated with the correct training and exposure. Acclimating to hot temperatures properly might mean the difference between performing at your best on race day and blazing past everyone or struggling and potentially crashing in the middle of the race. So, what are your options?
Many athletes are using heat to up-regulate regular endurance training adaptations, similar to how high-altitude exposure has resulted in beneficial changes. Sweat response for heat dissipation and core temperature management, as well as plasma volume and heart rate, all improve when you practise becoming used to the heat. We propose that sauna bathing after exercise be used to elicit heat acclimation responses and hence increase physiological performance. Sauna bathing after a workout involves soaking in the hot, dry heat of a sauna for 30-40 minutes. The logic behind this strategy is that you've already disturbed and stressed your body by exercising, and now you're in a very hot environment, which will raise your core temperature and sweat rate even more when you're at rest. Because increases in core and skin temperature are apparently at least part of the mechanism behind the heat acclimatisation responses we see with training in hot environments, we should expect some of these adaptations with post-exercise sauna bathing. In the coming months, going to the sauna a few times a week will help you prepare for Thailand's hot and humid climate. Finding a hot yoga/Pilates studio or not using your fan during a wind session are two other ways to boost your heat adaptation (with reason). When undertaking these sessions, remember to drink enough of water and electrolytes. Don't make Thailand any more difficult than it needs to be; instead, find the nearest sauna and start acclimating!
