Impact of EPOC adjustment on estimation of energy expenditure using activity monitors

Abstract

The activity monitors tended to underestimate EE during moderate and vigorous treadmill and cycling activities. The EE estimates from the activity monitors did not account for the energy cost met by anaerobic means during activity, as suggested by the higher EPOC-adjusted EE error rates.

Reliability and Validity of Commercially Available Wearable Devices for Measuring Steps, Energy Expenditure, and Heart Rate: Systematic Review

“…A total of 36 studies (312 comparisons) examined wearable device energy expenditure measurements compared with reference standard criterion measures, including direct calorimetry [ 86 , 104 ] and indirect calorimetry [ 20 , 21 , 29 - 31 , 38 , 39 , 41 - 43 , 53 , 55 , 63 , 66 , 73 , 85 , 87 , 93 , 95 , 97 , 103 , 105 , 116 , 117 , 129 , 130 , 142 , 143 , 146 , 148 , 159 , 165 , 166 , 177 ], in controlled settings. Of these, 35 studies recruited healthy adults (mean age 27.2 years, SD 7.1 years), and one study recruited adults living with cardiovascular disease (mean age 64.2 years, SD 2.3 years).…”

Review of Validity and Reliability of Garmin Activity Trackers

“…Twelve studies assessed validity of the Garmin activity trackers to assess energy expenditure including the: Forerunner 225 (Dooley et al, 2017) Generally, CC comparing agreement ranged from low to substantial (Boudreaux et al, 2018;Brooke et al, 2017;Price et al, 2017;Reddy et al, 2018;Wahl et al, 2017), with high variability across devices and studies (Figure 3a). In most cases, the MAPE was unacceptable (Figure 3b) (Boudreaux et al, 2018;Brooke et al, 2017;Dooley et al, 2017;Pribyslavska et al, 2018;Reddy et al, 2018;Roos et al, 2017;Wahl et al, 2017;Woodman et al, 2017). The MPE was also large for many different activities (Pribyslavska et al, 2018;Reddy et al, 2018).…”

The MPE was also large for many different activities (Pribyslavska et al, 2018;Reddy et al, 2018). Three studies not reporting CC or MAPE found large mean differences between the Garmin assessment of energy expenditure and the criterion measure during physical activity (Alsubheen et al, 2016;Hongu et al, 2013;Yavelberg et al, 2018).…”

Time‐restricted feeding combined with aerobic exercise training can prevent weight gain and improve metabolic disorders in mice fed a high‐fat diet

“…Calorimetry test also showed a peak $${\dot V_{{{\rm{O}}_{\rm{2}}}}}$$ after a period of running, reflecting a response to exercise known as excess post‐exercise oxygen consumption (EPOC), which represents an additional energy expenditure to that generated during exercise, indicating an increase in oxidative metabolism (Gaesser & Brooks, 1984; Speakman & Selman, 2003; Pribyslavska et al . 2018). EPOC is a major metabolic modulator of body mass, and this response to AE training in our work may have contributed to the body mass control of the TRF+Exe group.…”
