Which type of exercise is shown to have a better effect on claudication?

Aerobic exercise has been shown to have a significant positive effect on claudication, which is a condition characterized by muscle pain or cramping in the legs due to inadequate blood flow during physical activity. The mechanism behind this improvement is central to how aerobic exercise influences vascular health and physical endurance.

Engaging in aerobic exercises, such as walking or cycling, promotes increased blood flow and improves the body's overall cardiovascular function. This type of exercise enhances the efficiency of the muscles in using oxygen and can stimulate the development of collateral circulation, effectively bypassing blocked arteries. Over time, individuals with claudication can experience an improvement in distance and duration of pain-free walking, which directly addresses their functional limitations.

In contrast, while resistance training has its own benefits for strength and muscle mass, it does not specifically target the mechanisms involved in claudication. Stretching exercises may improve flexibility and range of motion but do not adequately address blood flow or the physiological adaptations that enhance endurance. High-intensity interval training can be beneficial for overall fitness, yet for claudication specifically, moderate, consistent aerobic activity has been empirically validated as the most effective approach.
