The Cooper Test is a physical fitness test designed to measure a person's aerobic capacity and endurance. Developed by Dr. Kenneth H. Cooper in the 1960s, it involves running as far as possible within a 12-minute time frame. The distance covered is then used to estimate the individual's maximum oxygen uptake, or VO2 max, which is a key indicator of cardiovascular fitness. This test is commonly used in various settings, including military training, sports, and physical education programs. It provides a simple and effective way to assess fitness levels and track improvements over time, making it a valuable tool for athletes and fitness enthusiasts alike.
