Metabolism changes in the heat impact protein needs

The body goes through a lot when exercising in the heat. On top of the sweat changes that occur there are several changes that occur in metabolism as well. Staying mindful of these changes will allow you to ensure you keep your body optimally prepared. Impacts on the metabolism affect what the body is predominately using during activity. Naturally in response then it impacts what needs to be consumed to optimally recover afterwards.

Performance in hotter temperatures

It shouldn’t come as a surprise but when in a hot environment, performance generally declines. On top of the stress being put on the body physically, it has the added stress of having to try cooling itself down. With that added stress, less focus is able to be purely devoted to muscles to maximize performance. With this divided focus, the metabolism is impacted to try and navigate everything going on

Glucose metabolism in the heat

Given all the craziness that the body is navigating, the body is needing a lot of energy. Not only is it needing a lot, it’s also needing it quickly! The nutrient that is able to most conveniently come to the rescue in a hurry is glucose and carbohydrates. To help with this, having some carbs pre-workout and during can be extra beneficial. If not provided enough glucose through food or drink the body will try to pull them elsewhere from glycogen or…..protein.

Protein metabolism in the heat

Protein is the key component of muscles and naturally we don’t want to make sure it’s being primarily used for muscle building and repair. Unfortunately, in certain situations protein gets prioritized and used for energy more than desired. Training in a hot environment is one of those situations.

Some amino acids (small proteins) are able to be converted into glucose. When the glucose within the body is being used rapidly, extra glucose needs to be provided from somewhere. This is where protein comes into the scene. Increased protein use for energy results in great muscle breakdown and increased overall soreness. To offset this, greater amounts of protein has to be consumed throughout the day. Nobody wants to lose their hard-earned muscle!

Adaptation decreases metabolism impact

Just like with hydration and sweat changes, as the body adapts to the heat so too does the metabolism. The overall stress on the body becomes less as it is less of a shock to the system. Giving the proper time to adapt then decreases that glucose utilization a little bit which preserves the body’s protein stores to decrease protein loss. So during the initial few days, keep these changes in mind to ensure maximum performance and recovery. Have a little bit of extra carbs around and ensure good protein is being consumed at meals and snacks.
