The Polar V800TM, A300TM, and Garmin Forerunner 235TM predict VO2max from a submaximal effort. Purpose: To examine the predictability of VO2max from two heart rate monitors (Device A and V) and a global positioning system (GPS) watch compared to measured VO2max. Methods: Forty participants, 22 males and 18 females ages 18 to 55, came to the Running Science Laboratory at Eastern Michigan University. During visit 1, participants completed a maximal graded exercise test (GXT) to determine VO2max. At visit 2, each device’s protocol was followed to estimate VO2max. Pearson correlations, repeated measures ANOVA, and a paired samples t-test were utilized to compare estimated VO2max values from the devices to measured VO2max from the GXT (p < 0.05). Results: Ten participants were excluded. The GPS watch revealed a RMANOVA p-value < .001 for participants with > 50 ml/kg/min VO2max. Conclusion: Even though there were moderate to strong relationships, all three watches underestimated VO2max compared to measured VO2max.
