Which of the following is an example of a chronic disease that can benefit from physical activity?

Diabetes is a chronic disease that has been shown to significantly benefit from regular physical activity. Engaging in exercise can help manage blood glucose levels, improve insulin sensitivity, and aid in weight management. Importantly, physical activity can reduce the risk of developing type 2 diabetes and can be an essential component of a comprehensive treatment plan for those who already have the condition.

In contrast, cancer is also a chronic disease, but its relationship with exercise is more complex. While physical activity can support overall health and improve quality of life for cancer survivors, it may not always be a direct treatment for the cancer itself.

Acute respiratory infections and the common cold are typically not classified as chronic diseases; they are transient conditions that do not benefit in the same way from long-term physical activity as chronic diseases do. In fact, they generally require different management strategies and do not have the same association with ongoing lifestyle changes such as exercise.

Thus, diabetes is the most suitable example among the options provided of a chronic condition that can gain direct benefits from physical activity.
