Cardiovascular training is specifically designed to enhance the efficiency and capacity of the heart, lungs, and circulatory system, which collectively improve cardiovascular endurance. This type of training engages large muscle groups over extended periods and promotes improvements in aerobic capacity, allowing the body to utilize oxygen more effectively during physical activity.

Enhanced cardiovascular endurance directly correlates with various health benefits, including increased stamina, better performance in physical activities, and reduced risk of chronic diseases such as heart disease and type 2 diabetes. It supports overall fitness by improving the body's ability to perform sustained exercises, leading to increased energy levels and overall well-being.

In the context of the other options, while increased muscle mass might result from resistance training, improved flexibility is typically associated with stretching and mobility work, and enhanced digestion is not a primary benefit linked to cardiovascular training specifically. Thus, the most accurate choice highlighting a key benefit of cardiovascular training is the improvement of cardiovascular endurance.
