Exercise is recommended as a major treatment component for individuals with Type II diabetes primarily for its positive impact on what?

Exercise plays a crucial role in managing Type II diabetes, primarily due to its positive impact on insulin sensitivity. When individuals engage in regular physical activity, their muscles become more adept at using glucose for energy, which enhances the body's ability to respond to insulin. This increased insulin sensitivity helps to lower blood sugar levels, making it easier to maintain glycemic control.

Moreover, exercise contributes to weight management, which is particularly important for individuals with Type II diabetes, as obesity can worsen insulin resistance. Through consistent physical activity, people can lose weight or prevent further weight gain, both of which are beneficial for improving insulin sensitivity.

While flexibility, cardiovascular endurance, and muscle strength are all important components of overall fitness and health, they do not specifically address the core metabolic concerns associated with Type II diabetes in the same way that improved insulin sensitivity does. Therefore, the focus on insulin sensitivity aligns directly with the management and treatment of this condition, making it the key reason why exercise is recommended.
