Background. The association between self-perceived and actual physical activity, with particular reference to physical activity guidelines,
may be an important factor in determining the extent of uptake of and compliance with physical activity.
Objectives. To examine the association between self-perceived and actual physical activity in relation to physical activity guidelines, with
reference to volume, intensity and duration of steps/day, and to establish the level of agreement between pedometer-measured and selfreported
ambulatory physical activity, in relation to current guidelines.
Methods. A convenience sample of adults (N=312; mean (standard deviation) age 37 (9) years), wore a pedometer (minimum 3 consecutive
days) and completed a questionnaire that included information on physical activity patterns. Analyses of covariance, adjusted for age and
gender, compared volume- and intensity-based steps according to meeting/not meeting guidelines (self-reported). The extent of agreement
between self-reported and pedometer-measured physical activity was also determined.
Results. Average (SD) steps/day were 6 574 (3 541). Of a total of 312 participants’ self-reported data, those meeting guidelines (n=63)
accumulated significantly more steps/day than those not meeting guidelines (8 753 (4 251) v. 6 022 (3 114) total steps/day and 1 772 (2 020)
v. 421 (1 140) aerobic steps/day, respectively; p<0.0001). More than half of the group who self-reported meeting the guidelines did not meet
guidelines as per pedometer data.
Conclusion. The use of pedometers as an alternative and/or adjunct to self-reported measures is an area for consideration. Steps/day
recommendations that consider intensity-based steps may provide significant effects in improving fitness and health.
