생활체육 동호인들의 신체활동 중 에너지소비량 추정을 위한 웨어러블 기기의 타당도 검증

Abstract

The purpose of this study was to verify the validity of wearable devices for estimating energy consumption during physical activity for sports club members in their 20s. In this study, absolute error and relative error were calculated to verify the error in the estimation of energy consumption between measurement tools, and repeated measured ANOVA analysis of variance was performed to verify the difference in the estimation of energy consumption. If there was a statistically significant difference in the repeated measured ANOVA analysis of variance, the dependent t test was performed to verify the difference in the mean value. Pearson correlation analysis was performed to verify the relative relationship of energy consumption estimates between measurement tools, and Bland-Altman plot was applied to confirm the error size between the measurement tool and the reference tool. As a result of the study, it was found that SenseWear Pro3(SWP) overestimates energy consumption during low-intensity physical activity and underestimates energy consumption during moderate-intensity and high-intensity physical activity. However, there was no statistically significant difference between the energy expenditure estimates of SWP and the energy expenditure estimates of the reference tool during moderate-intensity physical activity. Also, as a result of Pearson
