What type of fitness test primarily evaluates aerobic endurance?

The Beep Test, also known as the Conconi Test or shuttle run test, is designed specifically to assess a person's aerobic endurance, which is the ability of the cardiovascular and respiratory systems to supply oxygen during sustained physical activity. During the test, participants run back and forth over a set distance at increasing speeds, guided by audio cues that beep at set intervals. As the pace becomes faster, it pushes the limit of the individual's aerobic capacity, making it an effective measure of cardiovascular fitness.

In contrast, other tests mentioned serve different purposes. The 1RM Test is focused on measuring maximal strength, indicating how much weight one can lift in a single attempt. The Vertical Jump Test evaluates power and explosiveness rather than endurance, assessing how high one can jump from a standing position. Lastly, the Sit and Reach Test measures flexibility, specifically in the hamstrings and lower back, and does not relate to aerobic endurance at all.
