Decreased underestimation, otherwise overestimation, within the the elderly and you will insufficient awareness of years-associated reduction in real function
As shown in Figures 3b and 3c, the correlation coefficients between EH and age (r = -0.117, p < 0.01) and between AH and age (r = -0.454, p < 0.01) were significant for the older adults, with the AH–age correlation coefficient significantly larger than the EH–age correlation (p < 0.01). This was not the case for the young adults (r = -0.093 and -0.066).
Figure 3d shows that the self-estimation error (? height) was significantly correlated with age for the older adults (r = 0.228, p < 0.01) but not for the young adults (r = -0.073, p > 0.1). As shown in Figure 3e, the ? height was significantly positively correlated with EH for both the older (r = 0.716, p < 0.01) and young (r = 0.755, p < 0.01) adults, indicating that self-estimation error generally reflect EH for both young and older adults. In contrast, shown in Figure 3f, the ? height was significantly negatively correlated with AH in the older adults (r = -0.389, p < 0.01), with no significant correlation in the young adults (r = -0.038, p > 0.1). This indicated that the self-estimation error in the older adults significantly increased (decreasing underestimation and approaching overestimation) as the physical step-over ability deteriorated.
Self-estimate off action-more function and falls
Interviews for falls revealed that 40 (11.6%) young-old and 32 (21.2%) old-old adults, a total of 72 older participants (14.6% of all the older participants), had experienced falls within a year. Figure 4 shows SOT performance for fallers and non-fallers. Two-way ANOVA showed that the non-faller had greater AH than that of the faller group, although EH did not significantly differ for the faller and non-faller groups. Furthermore, 20 out of 72 fallers (27.8%) and 68 out of 422 (16.1%) non-fallers failed to step over the bar at the EH (i.e., overestimation), with these percentage data significantly differing for fallers and non-fallers (p < 0.05).
Comparisons of SOT performance of EH and AH between the fallers and non-fallers. The main effects of SOT performance (F1, 492 = 9.35, p < 0.01) and non-fallers/fallers (Fstep 1, 492 = 13.2, p < 0.01) were significant, with the interaction between the two factors being also significant (F1, 492 = 4.58, p < 0.05). The graphical symbol of “**” indicates p < 0.01. SOT, step-over test; EH, estimated height; AH, actual height.

Our very own performance indicated that 17.8% out of society-hold older adults didn’t action over the bar within estimated limit peak (i.elizabeth., EH), while all of the teenagers succeeded regarding the SOT samples in the EH. Furthermore, contrasting between EH, AH, together with resultant quote error (? height) indicated that brand new older adults had a tendency to overestimate, otherwise take too lightly so you can a lower the amount, SOT ability, compared with the students adults.
