Understanding the Input Fields
Before calculating your VO2 max, you’ll need to provide some basic personal information that helps us accurately estimate your cardiovascular fitness level. First, enter your age in years – this is crucial because VO2 max naturally declines with age, and your results will be compared against others in your age group.
Next, input your weight and select whether you’re measuring in kilograms or pounds using the unit dropdown – weight affects the calculation because VO2 max is expressed relative to body weight (ml/kg/min).
Finally, select your gender (male or female) as this influences the formula since men and women typically have different cardiovascular capacities due to physiological differences like heart size, lung capacity, and hemoglobin levels. These three pieces of information form the foundation for personalizing your VO2 max calculation and ensuring your results are accurately compared to appropriate reference standards.
The Cooper Test
Choose between two proven tests based on your fitness level. The Cooper Test requires you to run or walk as far as possible in 12 minutes – afterward, simply enter the distance you covered (in meters, kilometers, or miles). This test suits runners and active individuals.
