How does aerobic exercise impact heart health in older adults?

Aerobic exercise plays a significant role in improving heart health, particularly in older adults. Engaging in regular aerobic activities, such as walking, swimming, or cycling, leads to enhanced heart endurance. This improvement means the heart becomes more efficient at pumping blood, which can support overall cardiovascular health. An increased heart endurance allows the heart to work less hard during both exercise and rest, which is crucial as one ages.

As individuals engage in aerobic exercise, their cardiovascular system adapts, leading to a range of positive outcomes, including lower resting heart rates, improved circulation, and increased oxygen consumption during physical activity. These adaptations indicate that the heart can handle increased workloads without undue stress, contributing to better long-term health outcomes.
