What is the resting rate for oxygen consumption (VO2) typically measured at?

1. 1.5 ml/1 MET

2. 3.5 ml/1 MET

3. 5.0 ml/1 MET

4. 7.5 ml/1 MET

The correct answer is: 3.5 ml/1 MET

The resting rate for oxygen consumption, commonly referred to as VO2 at rest, is typically measured at 3.5 milliliters of oxygen per minute per kilogram of body weight, equivalent to 1 MET (Metabolic Equivalent of Task). This benchmark represents the standard metabolic rate for an average individual at rest and is essential in exercise physiology for assessing physical fitness and energy expenditure. Using 3.5 ml/1 MET as a standard provides a reference point for calculating how physical activity increases oxygen consumption. For instance, when an individual performs exercises with a higher intensity, their VO2 increases well beyond this resting level, and the difference helps trainers and exercise scientists quantify exercise intensity and caloric expenditure during various activities. Understanding this concept is crucial for personal trainers as it allows them to create exercise programs that are tailored to the individual's fitness level and metabolic responses, ensuring effective and safe training regimens.
