Abstract

The purpose of this study was to compare estimation accuracy of an accelerometer (Lifecorder Ex: LC) and a wristband type accelerometer (ViM sports memory: ViM) during non-locomotive activities. We chose fifteen activities. Fourteen young adults (7 males and 7 females) participated into 8 activities at least. An indirect calorimeter (MetaMax 3B) measured metabolic equivalent (MET) throughout all activities. Participants wore the LC on their hip and the ViM on non-dominate their wrist to estimate MET. To estimate MET, LC derivations (LC1 and LC2) were used and ViM derivations (ViM1 and ViM2) were used. Differences between MET and each estimates were analyzed by 2-way repeated ANOVA model in mixed model. Both of the LC1 and the LC2 significantly underestimated MET during most of activities (p ≤ 0.008). The ViM1 was significantly different from MET for all activities (p < 0.001), while the ViM2 showed not significant differences to MET during Dynamic stretch, Darts, Active video game (boxing), and Walking (p ≥ 0.162). These results show that the ViM can assess MET during non-locomotive activities more accurate than the LC and the LC consistently underestimates MET during all of non-locomotive activities.
