Final answer:
The type of acute injury that occurs in a muscle is a muscle strain, which involves the tearing of muscle fibers due to overstretching. Symptoms may include pain, stiffness, and bruising, and the injury is commonly treated using the PRICE protocol, consisting of Protection, Rest, Ice, Compression, and Elevation.
Step-by-step explanation:
When considering types of acute injuries that can occur in a muscle, the correct answer is a muscle strain. A muscle strain is when muscle fibers tear due to overstretching, which is often referred to as a pulled muscle or torn muscle. This kind of injury can range in severity and typically causes symptoms such as pain, stiffness, and potential bruising. For example, hamstring strains are not uncommon in athletes, particularly those in track and field. If an athlete has suffered from a hamstring strain in the past, they're at a higher risk of experiencing one again.
To help treat a muscle strain, it is recommended to follow the five-step PRICE protocol: Protection, Rest, Ice, Compression, and Elevation. Applying soft padding, resting the muscle, using ice and compression to reduce swelling, and keeping the affected muscle elevated can all assist in accelerating the healing process and preventing further injury.
