Which statement is true for both muscle fatigue and muscle injury?

A. Are caused by physical damage to thick and thin filaments
B. Are caused by the accumulation of metabolic by-products
C. Cause temporary decreases in muscle force production
D. Exercise training programs have no effect on their onset



Answer :

Final answer:

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.


Explanation:

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.
