Which of the following chronic diseases can be prevented through regular exercise?

Regular exercise plays a significant role in the prevention of Type 2 diabetes by enhancing insulin sensitivity and glucose metabolism. Through consistent physical activity, the body becomes more efficient at managing blood sugar levels, which is crucial for preventing this disease. Exercise helps to maintain a healthy body weight, which is another important factor in reducing the risk of Type 2 diabetes since obesity is a major risk factor for its development.

On the other hand, while there is research suggesting that regular physical activity might have beneficial effects on cognitive function and may reduce the risk of Alzheimer’s disease and possibly other neurodegenerative diseases, there is currently no definitive evidence that exercise can prevent these diseases. Multiple sclerosis is an autoimmune disorder with a complex etiology that is not directly linked to exercise as a preventive measure. Similarly, while exercise can improve quality of life and manage symptoms in individuals with Parkinson’s disease, it is not known to prevent its onset. Consequently, the most substantiated relationship regarding exercise and chronic disease prevention is with Type 2 diabetes.
