I think you are talking about the effect of exercise on the human body. There's two types of respiration humans use, when exercising - aerobic respiration - when oxygen is plenty, thus when you are not panting and getting enough oxygen you are using the kind of respiration. It requires the prescence of oxygen and glucose and produces 38 ATP and carbon dioxide, which is is exhaled. The other respiration, when you are panting and not gettiong enough air, is called anaerobic respiration. It only requires the prescence of glucose and only produces 2 ATP and lactic acid, which attacks your muscles, making you feel fatigued and produces muscle pain. Hope this anmswers your question. Fun Fact: The more time it takes for your body to go into anaerobic respiration, the more fit you are ! :)
Depends on the circulatory system
Striated (or skeletal) muscle
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
By a muscle that fails to relax completely resulting in the muscle going into spasm.
Muscle loss. Have you not been eating?
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.
Muscle fatigue has a number of causes including ion imbalance within the muscle or nervous fatigue. And most importantly, from the accumulation of lactic acid in the muscle.
