Firefighters Aerobic Capacity

VO2 is an index of the body's efficiency at producing work.


results:

VO2 max is an abbreviation for the maximum rate (Volume) at which your body can consume oxygen (O2) during exercise. It is widely used as an indicator of cardiorespiratory fitness.

Evidence

VO2 max is the total amount of oxygen you breathe in. This amount doesn't depend on your age, weight, height, and gender. It's measured in liters per minute. It is recommended by the US National Fire Protection Agency to assess aerobic capacity (VO2 max) in firefighters

FORMULA

the formula used to calculate VO2max based on exercise time on a treadmill (TT), Body Mass Index (BMI), age, and gender is:

VO2max=56.981+(1.242×𝑇𝑇)−(0.805×𝐵𝑀𝐼)

This formula does not directly use age and gender as inputs in the calculation of VO2max. However, age and gender are used to determine the fitness category of the calculated VO2max value. The categories are defined based on the VO2max result and differ for males and females across various age groups, with specific VO2max thresholds assigned to categories ranging from "Very Poor" to "Excellent".
