It's called muscular "tension."
.
Muscle cells are called fibers.
Muscle hypertrophy
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
Motor unit = the single motor neuron and the multiple muscle fibers that it innervates.

fibers
The scientific name for a muscle cell is a myocyte. Myocytes are also sometimes called muscle fibers. They are long, tube shaped, cells that develop from myoblasts.
Muscle hypertrophy
What happens when a muscle shortens is that it is contracting. This is when the fibers of the muscles generate tension.

Muscle contraction is affected by four factors:1. The number of muscle fibers stimulated 2. The relative size of the fibers 3. Frequency of stimulation 4. The degree of muscle strength

You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
Fast twitch muscle fibers are Type II muscle fibers. These muscle fibers have high explosive power and are anaerobic. They have a fast contractile speed and can reach peak tension in 50ms. They have a high glycolytic capacity and have low to moderate resistance to fatigue. Their motor unit strength is high.Slow twitch muscle fibers are Type I muscle fibers. These muscle fibers have steady power and are aerobic. The have a slow contractile speed and needs 110ms to reach peak tension. They have a low glycolytic capacity and a high resistance to fatigue. Their motor unit strength is low.
