Depends on the circulatory system
Fatigue of skeletal muscle may result from a variety of factors, including depletion of energy stores such as ATP and glycogen, accumulation of metabolic byproducts like lactic acid, and disruption of calcium ion homeostasis. Additionally, neurotransmitter depletion at the neuromuscular junction can contribute to muscle fatigue. Prolonged or intense muscle activity can also lead to oxidative stress and damage to muscle fibers, further exacerbating fatigue.

Skeletal muscle
A skeletal muscle.
Skeletal muscle fatigue is primarily attributed to a combination of factors, including the depletion of energy substrates (like ATP and glycogen), the accumulation of metabolic byproducts (such as lactic acid), and impaired calcium handling within muscle fibers. Additionally, changes in the nervous system's ability to stimulate muscles can contribute to fatigue. These factors together hinder muscle contraction efficiency and reduce overall performance during prolonged or intense physical activity.
straited muscle are another form of skeletal muscle.
The skeletal muscle is heavily stratified
Cardiac muscle and skeletal muscle have some similarities in structure and function, but also key differences. Both types of muscle are striated, meaning they have a striped appearance under a microscope. However, cardiac muscle is involuntary and found only in the heart, while skeletal muscle is voluntary and attached to bones to help with movement. Cardiac muscle has intercalated discs that allow for rapid communication between cells, while skeletal muscle fibers are individual cells. Additionally, cardiac muscle has a longer contraction time and does not fatigue easily, while skeletal muscle can contract quickly and tires more easily.
Actually, Skeletal muscle in and of itself is a TYPE of muscle. There are three types of muscle.1.) Skeletal - the muscles that help us move around daily and are under voluntary control2.) Cardiac- the heart muscle basically3.) Smooth- these muscles are under involuntary nervous control. For example, the muscles in your digestive tract contract to move food downward. You don't have to think to initiate contractions do you? :)Skeletal Muscle can further more be broken down into fiber types I, II( IIa, IIb, IIx)type I muscles are slow twitch- highly resistant to fatigue. Type II are fast-twitch and have a low resistance to fatigue.
