Muscle fatigue and muscle injury are linked to physical damage to muscle filaments and the accumulation of metabolic by-products, causing temporary decreases in muscle force production.
Muscle fatigue and muscle injury share similarities in their effects on muscle function. Both conditions can be caused by physical damage to thick and thin filaments, leading to temporary decreases in muscle force production. Additionally, they can both result from the accumulation of metabolic by-products such as lactic acid, contributing to their onset.
