Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
Muscle cells are called fibers.
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
There are basically two types of muscle fibers in our bodies that we have voluntary control over. One is called "red" muscle, and the other is called "white". Red muscle fibers have the ability to perform work over longer periods of time without fatigue. White muscle fibers are able to work hard, but for a shorter period of time than red fibers. An endurance athlete will have exercised his or her red muscle fibers (through long exercise sessions), so that they grow stronger and bigger. This means that their body will have the ability to do work for much longer than a person who only exercises for shorter periods (and exercises their white muscle fibers).
Fibers of the conduction system of the heart is called Purkinje fibers
A natural cluster of wool fibers is called a fleece.

They are called Fibers
Individual fibers wrapped within a CT sheath is called an endomysium.
