Which of the following should be initiated after a muscle cramp?

Initiating a stretch of the affected muscle after experiencing a muscle cramp is the most effective immediate response. Stretching helps to alleviate the tightness and tension in the muscle fibers, promoting relaxation. Gentle stretching can also enhance blood flow to the area, which may aid in the recovery process.

Keeping the muscle inactive, moving it forcefully, or ignoring the cramp would not address the immediate discomfort or assist in relief. In fact, keeping the muscle inactive may prolong the cramp or lead to stiffness, while forceful movements could exacerbate the situation and potentially cause injury. Ignoring the cramp does not provide any resolution to the pain or tension being experienced. Thus, stretching is the recommended action to provide relief and promote recovery from a muscle cramp.
