Pedometers for work site environment

Hi team,

I'm doing some work with a work-place in Melbourne, Australia. They have 150 workers, all walking on a concrete, mainly flat surface for up to 20 km per day we think. The aim is to find out actually how far they travel during a 12 hour shift.

It is within a large warehouse situation, but with some steps being taken around a pellet with crates on it. It is the small step down that seems to be throwing out the pedometer we are using from Sports Medicine Australia (10,000 steps SW-700). The readings we have got are around 36km for one worker and doesn't reflect how hard he worked/far he walked in that day (seemed far too much).

Any ideas of super reliable Pedometers that may allow for sensitivity to be adjusted?

thanks in advance,

Gareth

We buy in bulk the cheapest one here for our knee OA study and have had no problemos with it or a previous one we used to use.

Effects of age, walking speed, and body composition on pedometer accuracy in children.
Duncan JS, Schofield G, Duncan EK, Hinckson EA.
Res Q Exerc Sport. 2007 Dec;78(5):420-8

The objective of this study was to investigate the effects of age group, walking speed, and body composition on the accuracy of pedometer-determined step counts in children. Eighty-five participants (43 boys, 42 girls), ages 5-7 and 9-11 years, walked on a treadmill for two-minute bouts at speeds of 42, 66, and 90 m x min(-1) while wearing a spring-levered (Yamax SW-200) and a piezoelectric (New Lifestyles NL-2000) pedometer. The number of steps taken during each bout was also recorded using a hand counter Body mass index (BMI) was calculated from height and mass, and percentage of body fat (%BF) was determined using hand-to-foot bioelectrical impedance analysis. The tilt angle of the pedometer was assessed using a magnetic protractor. Both pedometers performed well at 66 and 90 m x min(-1), but undercounted steps by approximately 20% at 42 m x min(-1). Although age group, BMI, waist circumference, and %BF did not affect pedometer accuracy, children with large pedometer tilt angles (> or =10 degrees) showed significantly greater percent bias than those with small tilt angles (< 10 degrees). We suggest that the style of waistband on the child's clothing is a more important determinant of tilt angle and thus pedometer accuracy than body composition. Our results also indicate that the NL-2000 pedometer provides similar accuracy and better precision than the SW-200 pedometer, especially in children with large tilt angles. We conclude that fastening pedometers to a firm elastic belt may improve stability and reduce undercounting in young people.

Assessing Pedometer Accuracy while Walking, Skipping, Galloping, Sliding, and Hopping.
Smith JD, Schroeder CA.
J Strength Cond Res. 2008 Jan;22(1):276-82.

The purpose of this study was to determine the accuracy of the pedometer when walking, skipping, galloping, sliding, and hopping. One hundred-two college students were fitted with a pedometer (Walk4Life LS-7010) at mid-thigh on the right and left of the hip. Participants then performed the randomly assigned movements for the length (26 m) of a hardwood court playing surface, during which time the investigator tallied the steps with a hand counter. Each step with the lead foot elicited a tally on the counter. Participants were instructed to perform the movement at a brisk pace, to jump-stop at the end of the court, and to remain still until after the pedometer reading was recorded. Repeated measure ANOVAs using the Bonferroni technique were used to compare differences between pedometer counts and hand counts. Significant differences were evident between the hand tally counts and readings from the right and left pedometers during all five locomotor movements (P < .01). Mean error was lowest between the hand tally and the average of the right and left pedometers while walking (-1.35 +/- 1.60) and hopping (-2.94 +/- 2.33), and increased while sliding (-6.42 +/- 4.78), galloping (-8.22 +/- 4.63), and skipping (-8.30 +/- 4.45). Results indicate the pedometer may not consistently register the vertical force produced by the trail foot contact, the lead foot contact, or a combination of the two while skipping, galloping, and sliding. Though the pedometer is a valid instrument when estimating physical activity levels, caution is urged when interpreting movements other than walking.
