Hi Everyone,
New poster here. I've had a membership here for a long time but have never posted. I have a question and was wondering if someone could help me out.
I understand that in exercise science, we measure "intensity" differently in the context of aerobic and anaerobic exercise. They are as follows;
Aerobic = % of maximum heart rate.
Anaerobic = % of one rep maximum.
While I understand the practical benifits of using these definitions, I don't fully understand the physiological basis of them. What are the physiological reasons for defining "intensity" in the above ways? My gut feeling tells me it has something to do with the rate of energy conversion, or in other words, energy conversion per unit time. I'm not sure of the details if this is in fact correct, however.
Could someone with an understanding of physiology and the changes that occur in the body when it does work, please explain why we use the definitions that we do. I am particularly interested in the anaerobic definition.
This is probably a basic question that I should know, but I'm a recovering HITer, so go easy on me.
Cheers,
Jeff
