Which of the following is indicative of an overuse injury due to excessive training or activity?

Bursitis is indicative of an overuse injury due to excessive training or activity. This condition involves inflammation of the bursa, which are small, fluid-filled sacs that reduce friction between tissues of the body, such as bone and tendon. When athletes or physically active individuals engage in repetitive motions or excessive training without adequate rest, the bursa can become irritated and inflamed, leading to bursitis.

This condition commonly occurs in areas like the shoulder, elbow, hip, or knee where repeated movements happen. It showcases the physical stress placed on the body due to prolonged and intensified activity, making it a classic example of an overuse injury.

In contrast, cardiovascular disease is a broad term encompassing various heart conditions, which are influenced by factors like genetics, lifestyle, and diet, rather than simply overuse. Hyponatremia refers to a low sodium level in the blood, often related to excessive fluid intake rather than increased activity alone. Palpitations involve irregular heartbeats and can arise from numerous causes including stress, anxiety, or medical conditions, rather than being directly linked to an overuse injury.
