3.5.2 OWNINDEX - FITNESS TEST RESULT

OwnIndex is a value that is comparable to your maximal oxygen uptake (VO in ml/kg/min), a commonly used descriptor of
2max
aerobic fitness. Aerobic (cardiovascular) fitness relates to how well your cardiovascular system works to transport and utilize
oxygen in your body. The stronger and more efficient your heart is, the better your aerobic fitness is. VO is a good indicator
2max
of performance capability in endurance and outdoor sports. OwnIndex or your preset VO value is used in the estimation of
2max
your energy expenditure.
If you want to improve your aerobic fitness, it takes a minimum of 6 weeks on average to see a noticeable change in your
OwnIndex. Less fit individuals see progress even more rapidly, while more fit individuals need more time. Aerobic fitness is
improved by exercise types that employ large muscle groups over longer periods of time (more than 30 minutes). OwnIndex is
based on your heart rate and heart rate variability at rest, age, gender, height, body weight, and the self-assessed physical
activity level given in the Settings: User menu.
