1. What is Resting VO2?

Resting VO2 refers to the volume of oxygen consumed by the body at complete rest. The standard value of 3.5 mL/kg/min (often called "1 MET") represents the average oxygen consumption of a person at rest.

2. How Does the Calculator Work?

The calculator uses the standard resting VO2 value:

Where:

• 3.5 — Standard oxygen consumption at rest (mL/kg/min)

Explanation: This value is multiplied by body weight to calculate absolute oxygen consumption (mL/min).

3. Importance of Resting VO2

Details: Resting VO2 serves as the baseline for calculating exercise intensity and energy expenditure. It's fundamental in exercise physiology, cardiopulmonary testing, and metabolic calculations.

4. Using the Calculator

Tips: Simply enter your body weight in kilograms to calculate both relative (per kg) and absolute resting VO2 values.

5. Frequently Asked Questions (FAQ)

Q1: Is 3.5 mL/kg/min accurate for everyone?
A: While this is the standard value, actual resting VO2 can vary slightly based on factors like body composition, fitness level, and metabolic rate.

Q2: Why is resting VO2 important in exercise?
A: It serves as the baseline for calculating exercise intensity and energy expenditure during physical activity.

Q3: How does resting VO2 relate to METs?
A: 1 MET equals the resting VO2 of 3.5 mL/kg/min. Exercise intensity is often expressed in multiples of METs.

Q4: Can resting VO2 change?
A: Yes, factors like training status, body composition, and certain medical conditions can influence resting metabolic rate and thus resting VO2.

Q5: What's the difference between relative and absolute VO2?
A: Relative VO2 is expressed per kg body weight (mL/kg/min), while absolute VO2 is total volume (mL/min).
