What kind of fitness test is commonly used to assess aerobic capacity?

The 12-minute run test is a well-established method used to evaluate aerobic capacity, which is the body’s ability to take in, transport, and utilize oxygen during sustained physical activity. This test often involves running or walking for a designated period (12 minutes) as far as possible, allowing for an assessment of endurance and overall cardiovascular fitness.

The distance covered in this time is then used to estimate an individual's VO2 max, which is a critical indicator of aerobic fitness. The activity engages large muscle groups and elevates heart rate, providing valuable information about one's endurance capabilities.

In contrast, the 1-rep max test primarily measures muscular strength, not aerobic capacity. Flexibility tests focus on range of motion in joints, and push-up tests are typically used to gauge muscular endurance and strength rather than cardiovascular fitness. Thus, the 12-minute run test stands out as the most suitable choice for assessing aerobic capacity among the options provided.
