Abstract

Aerobic capacity (VO2peak ) testing equipment can be expensive. Garmin fitness watches are significantly cheaper, and Garmin has developed a fitness test that estimates VO 2peak . The purpose of this study was to validate the Garmin fitness test, using a Garmin Forerunner 920XT fitness watch, against VO 2peak measurement, using a Parvomedics TrueOne 2400 open circuit spirometry device. Sixteen college students (10 male and 6 female) volunteered to complete the Garmin fitness test followed several days later by a Bruce treadmill test while oxygen consumption was measured via open circuit spirometry. The average VO 2peak from the Garmin test was 45.4 (± 5.6) ml/kg/min, compared to 45.0 (± 8.9) ml/kg /min from open circuit spirometry. There were no significant differences between the measurements (t = 0.221 with p = 0.828). The two measurements were highly correlated with a correlation coefficient of 0.84 (p =0.000). The Garmin fitness test seems to be a highly accurate estimation of VO 2peak2peak.
