Question

Quizplus · Accepted Answer

Cardiovascular fitness refers to the ability of the heart, lungs, and blood vessels to efficiently deliver oxygen and nutrients to the muscles during prolonged periods of physical activity. Aerobic exercise, which involves continuous and rhythmic movements that elevate the heart rate and require a sustained effort, is the most effective way to improve cardiovascular fitness. Anaerobic exercise, which involves short bursts of intense activity that do not rely on oxygen as the primary fuel source, can improve muscular strength and power but does not have the same benefits for cardiovascular health. Anabolic and isometric exercise do not directly target cardiovascular fitness.
