Training in the Heat? Acclimatization?
I have a quick comment/question. I train a lot of young athletes like hockey players and lacrosse players, as I was a former hockey player myself ...but it also run a boxing gym, as I cut into Boxing and boxed professionally for a few years. I keep the gym. Relatively warm, even though we have air conditioning. I want the athletes, especially the boxers, to get comfortable with being uncomfortable. When I was boxing professionally, I was training with sweatsuits on in the heat and obviously it was very uncomfortable, but I got really used to it. Is there a level of a acclimatization when training in the heat or cold weather? I got really used to training in the heat and could deal with it very, but I know there are a number of performance decreases as soon as the heat increases. Would love to know some thoughts.

Yes—there is a level of acclimatization to heat and cold. According to CSCS principles, repeated exposure to training in hot environments (usually over 7–14 days) leads to heat acclimatization: earlier onset of sweating, increased plasma volume, improved skin blood flow, and lower core/skin temperatures during exercise. This helps reduce physiological strain, but performance can still decrease in extreme heat. Cold acclimatization is less pronounced, but repeated exposure can blunt shivering and improve peripheral blood flow. So while training in heat can improve tolerance, it doesn’t make athletes immune to performance decrements or safety risks (e.g., dehydration, heat illness). .
