Hot Temperatures - Should You Adjust Your Power On The Bike?

One of the biggest opponents athletes have is heat, no matter if it is during training or on race day…it can be equally challenging. According to research conducted by Stanford University, humans achieve only 20-30% mechanical efficiency cycling with the majority of the energy being produced being lost as heat. Taking this a step further, anaerobic threshold power output declines as air temperature increases. Putting this into perspective, how does this information impact training and racing approaches? We provide you with two options including additional insight

Hydration – Pay attention to your Thirst! 

Our thirst gives us important cues on hydration by just listening to our body. 

Why do we sweat?

                  Sweat keeps us cool and blood vessels open up so that the heat we produce can radiate off. 

                  Our bodies consist of 60-75% water (more muscles = more water) accompanied with minerals, like sodium, potassium, and chloride. As we sweat (made up of 90% of electrolytes) and water from the sweat evaporates, it takes heat with it and what is left behind is the salt that came out of the skin (the white marks on your jersey). Even though all electrolytes are important to our body’s function and performance, sodium is the most important one.
