Explanation:
Muscle stiffness is multifaceted and can result from factors such as overworked muscles, cellular damage after intense exercise, improper alignment of joints, lack of warm-up before exercises, and myosin heads not detaching from action-binding sites. Muscles gain mass as the damage is repaired, a process called hypertrophy. This contrasts with the atrophy process where sarcomeres and myofibrils disappear but the number of muscle fibers remains.
Stiff muscles do not only result from overworking them but can be due to various factors. Improper resistance training, for instance, can lead to overused muscles, tendons, or bones resulting from too heavy loads or insufficient recovery time between workouts. Other causes include cellular damage to muscle fibers after intense exercise and joints not properly aligned. Besides, the condition of muscles being rarely completely relaxed or flaccid also contributes to muscle stiffness.
However, it's worth noting that muscles gain mass as the muscle damage is repaired, and additional structural proteins are added to replace the damaged ones. This is referred to as hypertrophy. The opposite process - atrophy, results in the disappearance of sarcomeres and myofibrils but not the number of muscle fibers, which can be observed when a limb casts are removed or in diseases like polio.
Everyday activities, such as exercise and stretching, matter too. Warm-up exercises increase blood flow to the muscles while stretching helps pull on the muscle fibers. Absence of a proper warm-up can result in damage to muscle fibers or a pulled tendon. Lastly, myosin heads not detaching from actin-binding sites results in muscle stiffness, causing conditions like 'writer's cramp' or rigor mortis in a recently deceased person.
