Final answer:
A hamstring strain is an injury where the muscle fibers in the hamstring are overstretched or torn, often causing pain, stiffness, and bruising. Risk factors include inadequate warm-up, previous injuries, and activities with extensive running. Treatment typically involves the PRICE method and NSAIDs.
Step-by-step explanation:
What is a Hamstring Strain?
A hamstring strain is an injury to the muscles at the back of the thigh. This type of injury occurs when the muscle fibers in the hamstring are overstretched or torn. Symptoms typically include pain, stiffness, and sometimes bruising over the affected area. Risk factors for a hamstring strain include a lack of proper warm-up, previous hamstring injuries, and activities that involve a lot of running or sprinting, as is common in track and field athletes.
Proper warm-up and stretching are important preventive measures to avoid such injuries. If a hamstring strain does occur, the recommended first aid is the PRICE method, which stands for protection, rest, ice, compression, and elevation, to reduce pain and inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs) can also be used to manage symptoms.
