Circadian rhythms play a crucial role in regulating various physiological functions of the human body and can impact the ability tasks. The aim of this study was to investigate the effect of time of day on static and dynamic balance using the cognitive task approach. We recruited 24 elderly men who performed both static and dynamic balance tests with and without cognitive dual tasks. Our statistical analysis, using a significance level of 0.05, revealed significant differences in the parameters of the 95% confidence ellipse, length of path, and average velocity of the center of pressure when performing the dual task compared to normal walking. However, these variables did not significantly differ at different times of the day. Interestingly, our results showed that the center of pressure fluctuations in closed eyes and different times of the day did not have a significant difference. Overall, our findings suggest that healthy elderly individuals are at similar risk of falling during different hours of the day. Nonetheless, the simultaneous execution of dual cognitive tasks leads to balance disruption in both eyes-arm closed positions. [ABSTRACT FROM AUTHOR] |
