As individuals age, there is a natural decline in the elasticity of the blood vessels, which is referred to as vascular compliance. This decrease means that the blood vessels become stiffer and less able to expand and contract in response to changes in blood flow and pressure. Consequently, during exercise, the cardiovascular system has a diminished ability to maintain adequate blood circulation due to these stiffened vessels.

This reduced vascular compliance impacts overall cardiovascular performance, making it more challenging for the body to efficiently deliver oxygen and nutrients to muscles during physical activity. This response is critical for personal trainers to understand, as they need to tailor exercise programs for older adults to accommodate these changes, ensuring that cardiovascular challenges are balanced with safety and effectiveness. Understanding the relationship between aging and vascular response is key for optimizing training regimens for older populations.
