Understanding VO2 Max

VO2 max is a crucial indicator of fitness, measured in milliliters of oxygen used per kilogram of body weight per minute. A score below 18 suggests a loss of independence, particularly for women, while average scores vary by age and sex. For instance, a 40 to 49-year-old female with a VO2 max of 28 is considered below average, highlighting the importance of maintaining fitness for daily living.
