AITank: Fitness Explained

Step into a gym and what do you notice first? The big guys right. What some people can transform their bodies into amazes all of us at some point or another. Men who look like descendants of Hercules himself. It is only natural for us to want to try and imitate these icons of strength and fitness, but before you set about training to be nothing but huge, ask yourself this. Do you just want to be able to move weight around, or be strong and immensely quick, explosive as I like to call it. The difference is this, being able to jump higher, run faster and exert force in general faster versus being able to pick up a tree or car real slow, but able to. Ridiculous examples but I think you get the point. The mechanical difference is the types of muscle fibers we recruit to perform certain tasks.

There are two types of muscle fibers, fast-twitch and slow-twitch or TypeII and TypeI. Within the TypeII class there are fast-oxidative-glycolytic TypeIIa and fast-glycolytic TypeIIb fibers. Contrary to what some people believe, both exert the same amount of force, it is simply the rate at which they do so that varies. TypeIIb fibers, as their name implies, are primarily anaerobic by nature possessing larger stores of glycogen and the enzymes necessary for anaerobic respiration, meaning they operate without oxygen. Adding to their architecture they have few mitochondria, the primary structure that is utilized for aerobic respiration.
