BACKGROUND : The FitTrack Index is a web-based programme developed in South Africa and
widely used by athletes to indicate their fitness. A need exists for a self-managed, noninvasive
tool to evaluate and categorise health-related fitness in different population
groups. The aim of this study was to compare the FitTrack Index with a reliable measure of
cardio-respiratory fitness as indicated by maximal oxygen uptake (direct VO2max).
METHODS AND RESULTS : During a 12-week cross-sectional, descriptive pilot study the direct laboratory
tested VO2max indicated a moderate to strong correlation with the FitTrack
Index (Spearman's rho ¼ 0.439, p ¼ 0.089 at baseline; Spearman's rho ¼ 0.853, p < 0.001 after 12
CONCLUSIONS : These results suggest that the web-based FitTrack Index may be considered an
appropriate tool to evaluate exercise capacity and cardiovascular fitness in healthy individuals
following an aerobic training programme.
