Pedometer Accuracy in Elementary School Children while Walking, Skipping, Galloping, and Sliding

Abstract

The purpose of this study was to examine the accuracy of the SW-701 (Yamax Corporation, Tokyo, Japan) and NL-800 (New-Lifestyles, Inc., Lee's Summit, Missouri, USA) pedometer in fifth-grade students while walking, skipping, galloping, sliding, and hopping. Counts registered by both pedometer models were significantly lower than actual counts while skipping, galloping, and sliding, and counts from the NL-800 were significantly lower than the SW-701 during these same movements. No significant differences in step counts were detected between actual counts and the SW-701 and between the pedometer models while walking and hopping; however, the NL-800 registered counts significantly higher than actual counts while hopping. Bland-Altman plots suggest the greatest variability occurred while skipping, galloping, and sliding, with the percent error lowest in the SW-701 during these movements.

Convergent Validity of a Piezoelectric Pedometer and an Omnidirectional Accelerometer for Measuring Children’s Physical Activity

“…A recent study investigating the accuracy of step counts in a pedometer that uses the same internal mechanism as the NL-1000 (NL-800) supported the notion that the mode of activity is an important determinant of pedometer accuracy (17). The latter authors observed significant underestimation of step counts (compared with a hand counter) when children were skipping, galloping, and sliding, with acceptable performance during walking and hopping.…”

“…Παλαιότερες έρευνες είχαν μελετήσει την ακρίβεια και εγκυρότητα καταγραφής βημάτων κυρίως μηχανικών βηματομετρητών σε παιδιά και εφήβους (e.g. Duncan, Schofield, Duncan, & Hinckson, 2007;Hart, Brusseau, Kulinna, McClain, & Tudor-Locke, 2011;Nakae, Oshima, & Ishii, 2008;Smith & Schroeder, 2010 (Nakae, Oshima, & Ishii, 2008). Όσον αφορά έρευνες σε ενηλίκες, η πλειοψηφία αυτών έχει καταλήξει στο συμπέρασμα ότι οι νέες συσκευές (π.χ.…”
