Sedentary women (n=92) classified as low (L), medium (M), and high (H) in baseline step counts and assigned to 10,000-step goal (TSG) and personal step goal (PSG) groups (within levels) were compared on goal attainment and step counts. A significant interaction for goal attainment, F(2, 86)=4.51, p=.014, indicated that the L group was significantly less likely to meet the TSG than the M and H groups. Step counts increased after goal assignment, but not more for one group than the other. Results of this research support the previous finding that women with low baseline step counts are unlikely to meet a TSG, but a TSG does not result in lower step counts than a PSG.
