Aerobic Threshold is the stage of an exercise at which an individual utilizes the most fat. The metabolism of fat requires oxygen (O2 + fat > CO2 + H2O + energy). The more oxygen that is required; the more carbohydrates play a role in energy production. Aerobic threshold is also considered to be the highest point of exertion at which the body can still eliminate the lactic acid generated during the course of a particular exercise or activity to such a degree that the level of lactic acid does not rise above the level sustained at rest. The AeT will differ amongst individuals, and will also vary between different activities. Beginners typically have a considerably low AeT of 46% - 55% of VO2 max. A professional athlete or elite athletic competitor may have an aerobic threshold in the high eighties or nineties.
I worked in construction for quite a while when I was younger. As a kid I was often told “it is good to have something to fall back on.” Other than the fact that the sentence ends in a preposition, it is absolutely correct. Having a trade skill has allowed me to work while I prepare myself to take my Master Trainer test again next weekend. It has also reminded me of how much I do not want to have to do manual labor in the 100+ degree weather here in Arizona. It wasn’t so bad when I was 20, but I’m not 20 anymore.
In related news I’ve landed a position as a Travel Coordinator (basically a travel agent). The great thing about this new job is that it is work from home. I start my training on Monday. It sounds like it is going to be a great deal of fun working with people who are traveling here from all over the world.
I’m so looking forward to doing what I love to do rather than what I have to do.
Just a couple more weeks…
