Many pedometers appear to be most accurate at 80 meters per minute or about 3 miles per hour (mph) (actually 2.98 mph).

Normal walking speed for most people is between 2 mph and 4.5 mph.

Whether a pedometer is worn on the left or right side does not appear to affect accuracy.

Excess fat at the waist may create inaccuracy.

The slower the walking speed, the more inaccurate the step count. This may be because the vertical accelerations of the waist (the pendulum movements) are less pronounced at slower speeds. Also stride length may be shorter than what is programmed in the pedometer.

Distance and caloric expenditure are estimated from the step data, using manufacturers proprietary formulas. Joanna's pedometers have been developed in conjunction with Walk4Life, independent studies have shown this pedometer step count to have a 1% error rate, the accepted industry error rate is 3%. A recent study in the British Medical Journal reported that different makes of pedometers can vary in accuracy with some models showing a 58% error rate. Obviously this amount of error is a major limitation for you achieving your goals whether you are walking for health, for fitness or wanting to address healthy weight management. Joanna Hall in conjunction with Walk4Life strive very hard to provide you with the most accurate and simplest pedometer available.

Consistently delivering results within 1% accuracy, the following independent studies have shown how Joanna's pedometer is THE ONLY pedometer to buy.

Most accurate measurement of activity at various speeds (March 2005. ACSM Medicine & Science in Sports and Exercise; Oregon State University, Corvallis: Beets, Patton, Edwards.)

Designated highest level of accuracy for use in research studies
(August 2003. ACSM Medicine & Science in Sports and Exercise ; University of Tennessee, Knoxville: Crouter, Schneider, Karabulut, Bassett)

Achieved consistent performance in a variety of terrains and settings (C. Van Der Bruggen, Queensland University of Technology, Australia; T. Cuddihy, University of Maastrich, The Netherlands; r. Pangrazi, Arizona State University, USA)
