Your OwnIndex is most meaningful when comparing your individual values and changes in them over
time. OwnIndex can also be interpreted based on gender and age. Locate your OwnIndex on the table
below, and find out how your aerobic fitness compares to others of the same gender and age.
Top athletes typically score OwnIndex values above 70 (men) and 60 (women). Olympic-level
endurance athletes can reach values as high as 95. OwnIndex is highest in sports that involve large
muscle groups, such as running and cross-country skiing.
