Fitness Level (Vo2 Max) - Withings ScanWatch Series Installation And Operating Instructions Manual

Fitness Level (VO2 max)

VO2 max is a key indicator of fitness. VO2 max is defined as the maximum
amount of oxygen an individual consumes over one minute during intense
physical effort. The more oxygen consumed, the harder muscles can work, and
therefore the higher the VO2 max level. A higher VO2 max level indicates a more
fit individual.
Medically, VO2 max can be measured by spiroergometry, where the person
exercising wears a mask designed to capture maximum oxygen absorption
capacity (VO2 max). The mask is worn in front of the mouth and face when
running or biking on an ergometer or treadmill.
The higher the VO2 max level is, the more oxygen can be converted in the
working muscles to provide energy, the higher is the corresponding endurance
capacity.
ScanWatch provides a VO2 max estimate based on data including heart rate, age,
gender, weight, and pace from a connected GPS running session.
What is the Fitness Level score?
Our Fitness Level assessment is calculated on the basis of several factors. The
most important ones include heart rate, age, sex, and weight, and they are
combined with the GPS data tracked by the ScanWatch during your running
sessions. The fitness level is then estimated by comparing your heart rate and
your running pace.
The higher your fitness level, the more fit you are. People with a higher VO2 max
usually have a lower heart rate during running sessions. People who are new to
the workout game have a higher heart rate at the same pace and therefore a
lower VO2 max.
To see an accurate estimate, you need to go on runs that are at least 10 minutes
long. It is also recommended that you run on flat terrain because running downhill
or uphill can put too much or too little effort compared to a flat run, which can
throw off the estimate.
Continuity is key: wear your ScanWatch with the GPS feature enabled every time
you go on a run. This not only delivers the most accurate measurement but also
tracks your cardio fitness development over time.
Note: Always consult with your doctor or trusted health professional before
beginning a new fitness routine.
