MUSCLE PHYSIOLOGY

Detailed explanation-1: -Muscle fatigue is defined as a decrease in maximal force or power production in response to contractile activity. It can originate at different levels of the motor pathway and is usually divided into central and peripheral components. Peripheral fatigue is produced by changes at or distal to the neuromuscular junction.

Detailed explanation-2: -Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following strenuous activity or exercise. When you experience fatigue, the force behind your muscles’ movements decrease, causing you to feel weaker.

Detailed explanation-3: -Fatigue occurring during exercise can be defined as the inability to maintain the initial force or power output. As fatigue becomes pronounced, force and maximum velocity of shortening are greatly reduced and force relaxation is prolonged.

Detailed explanation-4: -Fatigue is defined as a decrease in the muscle’s ability to generate force. Fatigue is caused by a reversible depletion of the muscle’s fuel supply. If the muscle uses its energy sources faster than they can be generated by cellular metabolism, fatigue occurs.
