Muscle is quite an amazing aspect of our bodies. Without it, it would be impossible to make any type of action, walk, talk, run or even make a simple gesture. Since muscle are so crucial, they are quite complex. They’re self-healing, long-lasting, and are able to be improved by hitting up the gym and lifting weights.
Skeletal muscle, or striated muscle, is the type of muscle fiber you work out when you lift weights. Like the name suggestions, skeletal muscle actually attaches to the skeleton. The basic movement of any muscle is contraction.
For example, when you’re hitting bicep curls, you’re using your brain sends a signal down a nerve cell to tell your bicep muscles to contract, and pull up the weight.
Muscles are made up of a bundle of fibers, and compared to other cells in your body, muscles are fairly large. Each muscle fiber contains many cylinders of muscle proteins, or myofibrils.
These proteins allow the cell of a muscle to contract. Myofbrils contain two types of filaments that run along the long axis of the fiber.
Our muscles are made up of two different, but basic types of fibers, fast twitch and slow twitch. Fast-twitch muscles are able to develope greater forces, contracting quicker, and have much more anaerobic capacity. This is why it’s a good idea to use both fast and slow tempos when you contract your muscles.
Bodybuilding increases muscle mass, by changing the size and number of fibers, rather than the types of fibers in the muscle.
