The fitness assessment that measures cardiovascular endurance is the VO2 max test. This test evaluates the maximum volume of oxygen an individual can utilize during intense exercise, serving as a key indicator of aerobic capacity and overall cardiovascular fitness. Higher VO2 max values indicate better cardiovascular health and endurance, allowing individuals to perform sustained physical activity effectively. Other assessments, like the Rockport Walk Test or the Cooper Run Test, can also provide insights into cardiovascular fitness. Evaluating cardiovascular endurance is essential for tailoring effective workout programs to improve health.
