A study by Belgians finds that pedometers, which are not upto the standard and cheaper does not measure every steps in an accurate manner.
Ghent university researchers have analysed nearly 1,000 pedometers involving 35 adults volunteers using 5 per day for 6 days. Automated step-count log precisely logged their steps were also followed by the volunteers. Finally both (pedometers and the automatic step log) were compared for accuracy.
About 2/3rd of the pedometers studied showed higher steps than recorded by the automated step log. Although a 10 percent variation was been accepted, nearly 3 out of 4 pedometers studied measured a higher variance - researchers said.
Report by the study authors, in the British Journal of Sports Medicine, says 'inexpensive (pedometers) provide incorrect information on step counts, which makes them inappropriate for physical activity promotion targets'.
