Which fitness component does not directly relate to cardiovascular capacity?

Muscular strength is the fitness component that does not directly relate to cardiovascular capacity. In contrast to cardiovascular endurance, which focuses on the efficiency of the heart, lungs, and blood vessels to supply oxygen during prolonged exercise, muscular strength pertains to the maximum amount of force that a muscle or group of muscles can exert in a single effort.

While cardiovascular endurance and aerobic endurance are essential for sustained physical activity and involve the body’s ability to deliver oxygen to muscles throughout extended exercise, muscular strength involves different physiological systems that do not primarily influence the cardiovascular system. This distinction emphasizes how muscle strength training and cardiovascular training address separate aspects of fitness, where one improves muscle force and the other enhances heart and lung function.
