It's hot these days in San Diego. I'm not enjoying it. The heat is limiting my miles and forcing me into the trailer-park of the running world, the treadmill.
What if we can make this heat work for us?
Studies have shown that training in the heat can have the same effect of training at altitude.Cycling or running in the heat has been shown to increase VO2 max, raise lactic acid threshold, and maximum cardiac output.
But what about hydration and heat stroke risks?
The current paradigm for hydration says to drink to thirst. If you are thirsty during a training session, drink. If you are not thirsty don't drink. It's that simple. It would appear that our bodies have a built-in regulation system. On a hot day, you will go slower and be thirstier. Heat stroke becomes an issue when you ignore the heat and try to push the pace.
In theory it is possible to "hyper-hydration" in the few minutes before a training session. This will create a bloated feeling for the first few minutes of the session. It's probably easier to just drink when you're thirsty.
