In my post about Cardiovascular/respiratory endurance I talked about three different metabolic pathways, the Phosphagenic, Glycolytic and Oxidative. And how Cardiovascular/respiratory endurance is not the same as Stamina.
If we look at the wikipedia definition of stamina it states “ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue”
So Stamina in the context of Crossfit has more to do with the body’s ability to quickly recover from the external forces imposed on it, rather than its ability to exert effort for prolonged periods of time, which is more related to Cardiovascular/respiratory endurance.
In other words stamina is what helps us deal with fatigue, the more stamina you have, the less easily you fatigue. Of course, there are different ways that stamina and fatigue can manifest. someone with high Cardiovascular/respiratory endurance would most likely have high stamina in the low intensity setting of a marathon. but the same athlete would have low stamina is the high intensity setting of weightlifting.
The Crossfit definition of stamina – The ability of body systems to process, deliver, store, and utilize energy. – highlights how stamina focuses on the body’s efficient use of energy. when you apply this ability across broad time and modal domains, which is what Crossfit training strives for, you’re ultimately tuning the bodys engine to be efficent no matter what ‘gear’ its in, with contributes not only to better performance, but also better health and well being.
