To assess cardiovascular fitness, one can perform various tests, such as the vo2 max test, which measures the maximum amount of oxygen consumed during intense exercise. Other methods include the 2-mile run test or the 1.5-mile run/walk test, assessing how efficiently the heart and lungs deliver oxygen to working muscles. Monitoring heart rate during physical activity can also provide insight into cardiovascular conditioning. Regular engagement in aerobic exercises helps improve overall cardiovascular fitness.
