EH and AH of the step-over test (SOT) for the 3 age groups. The main effects of SOT performance (F_{1, 562 =} 34.9, p < 0.01) and age (F_{2, 562 =} 34.6, p < 0.01) were significant, with the interaction between the two factors being also significant (F_{2, 562 =} 40.2, p < 0.01). The graphical symbol of “**” indicates p < 0.01. EH, estimated height; AH, actual height.
