Abstract | The recent compilation of pedometer-determined physical activity studies of youth by Tudor-Locke and colleagues (Tudor-Locke, McClain, Hart, Sisson, & Washington, 2009) is a valuable addition to the growing field of physical activity assessment via pedometry. In this study, Tudor-Locke and colleagues presented an "expected" habitual daily step-curve beginning from ages 6 through 18 years based on 22 studies. They provided median steps/day values from studies that represented boys and girls, separately, and for each year of chronological age. While the study is informative, three caveats require additional consideration. First, prior research (Vincent, Pangrazi, Raustorp, Tomson, & Cuddihy, 2003), albeit limited in number, suggested there is considerable disparity among countries for the average daily steps taken by youth. Second, the use of the median steps/day (the middle average steps/day from lowest to highest values reported from the included studies) and the inattention to weighting these values provided estimates that did not fully account for the differences in the amount of information each study contributed. Third, presentation of the expected step-curve provided estimates that challenge common sense. Such considerations as above will facilitate a greater understanding of the differences and similarities in pedometer-determined physical activity of youth over time. (ERIC). |
