Accuracy of predicted energy expenditure from a Fitbit Inspire HR activity monitor during short- and long-duration exercise

<p>PURPOSE: To determine the accuracy of predicted Energy Expenditure (EE) reported by a wrist-worn activity monitor compared to measured EE during both a long- and short-duration exercise. METHODS: In addition to a VO_2max treadmill test, a running speed at approximately 70 - 75% of that VO_2max was found during the first visit. The second and third visit was comprised of either a 30-minute or 10-minute run at the speed previously determined. A wrist activity monitor was worn and VO2 and EE were recorded by a metabolic cart. Pearson correlation, paired samples t-test, and repeated measures ANOVAs compared predicted and measured EE. An independent samples t-test determined significant differences in characteristics between fitness groups (<em>p</em> < 0.05). RESULTS:<em> N = 25 (60% male)</em>. A significant correlation was found between predicted EE and measured EE for both short and long duration (<em>p</em> < 0.001). The repeated measures ANOVA determined the interactive effect of measurement mode and fitness level was significant. CONCLUSIONS: Overall, there is a strong correlation between criterion and predictive measurement, however, consumers should exercise caution when using predicted measures.</p>
