Muscle fatigue has been suggested as one factor that can increase the chances of non-contact sports injuries, such as anterior cruciate ligament (ACL) tears. Notably, some researchers have noted a delay in the reflex response after muscle fatigue. With your understanding of the stretch reflex, which of the following is the most logical contributing factor to the injury? a. the distraction of the game causes inhibitory impulses to be sent down from the somatosensory cortex, so muscles are not operating at full capacity b. the proprioceptors adapt and become less sensitive c. there is an increase in time to muscle contraction after triggering a reflex

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
