What effect does exercise have on blood flow?

It decreases blood volume.
It increases heart rate variability.
It increases capillarization of trained muscles.
It reduces blood flow to active muscles.

The correct answer is: It increases capillarization of trained muscles.

Exercise has a significant impact on blood flow, particularly through the process of capillarization in the muscles that are regularly trained. When a person engages in consistent physical activity, the body adapts by creating more capillaries in the trained muscles. This process enhances the blood supply to those areas, allowing for improved oxygen and nutrient delivery as well as better removal of metabolic waste products during exercise. The increase in capillaries improves the efficiency of the cardiovascular system and supports greater endurance and performance in activities requiring muscular effort. Thus, the correct choice highlights the positive adaptive response of muscle tissues to regular exercise, emphasizing the physiological benefits associated with an active lifestyle.
