Final answer:
Activity-related physical injuries, such as muscle strains and tendonitis, result from biomechanical stresses like sudden exertion or repetitive motions. Prevention includes proper safety equipment, and warm-up and stretching exercises. These injuries can affect muscles, tendons, skin, or even the brain and vary in severity from mild to severe.
Step-by-step explanation:
Activity-Related Physical Injuries
Activity-related physical injuries are conditions that arise due to various biomechanical stresses on the body during physical activities. These disorders can result from sudden exertion, over-exertion, repetitive motions, or maintaining awkward positions for extended periods. Common examples include muscle strains, tendonitis, and carpal tunnel syndrome.
Characteristics of Injuries
Muscle strains, also known as pulled muscles, occur when muscle fibers or tendons tear due to overstretching. Strains often present with pain, swelling, and limited movement. Tendonitis is the inflammation or irritation of tendons, typically caused by repetitive stress or overuse. Signs of tendonitis include pain, tenderness, and possibly swelling around a joint.
Preventing Injuries
To prevent these types of injuries, it is important to wear the correct safety equipment, warm-up, and cool down properly, and to stretch before and after physical activities. This helps to minimize the risk of bone, ligament, and muscle injuries.
Skin injuries such as burns, wounds, scars, and calluses can occur through interactions with sharp objects, heat, or excessive pressure or friction. Brain injuries, which can be due to falls, accidents, or sports, range in severity but always require medical attention.
