The purpose of this study was to clarify the differences between the visual and walking estimations of the target distance and how they are affected by the changes of participants’ heart rates. Eight healthy subjects participated in this study. They were required to estimate the distances ranging from 1 to 8 meters either by visual measurement or by walking measurement, with the distances set randomly. These estimation tasks were conducted on the participants both at resting state and with elevated heart rate. The stimulus to increase their heart rates was upper body exercise so as not to affect the participants’ gait. The estimation results were grouped into one for the shorter distance (1-4.5 m) and the other for the longer distance (4.6-8 m), and the errors from the correct distances were compared, respectively. For statistical analysis, t-test and two-way ANOVA were performed at a significance level of 0.05. With regard to the shorter distance estimation, there was no significant difference between the visual measurement and the walking measurement one for the participants at resting state, but a significant difference was observed among those with their heart rate elevated. On the other hand, as for the long distance estimation, there was a significant difference between the visual measurement and walking measurement for both conditions and two-way ANOVA showed that there was an interaction only at short distances (p<0.05). This suggests that an elevated heart rate tends to cause errors in visual measurement at short distances, and that walking measurement can be more accurate than visual measurement in estimating distances. The results of this study mean that an athlete’s heart rate may have an influence on their performances such as putting in golf under great psychological stress.
