ABSTRACT

PURPOSE:

Few studies have addressed the effect of diurnal circadian rhythms on postural stability, and thus the aim of the present study was to examine circadian effects on static and dynamic postural stability in young adults.

METHODS:

Twenty-four subjects (9 men, 11 women age=22.20±1.77, height=167.20±10.47, weight=59.85±10.66) from a university community volunteered for this study. Static and dynamic balance testing, which recorded using a Good Balance system (Good Balance, Metitur Ltd, Finland) was conducted at 900, 1300, and 1700 hours on two consecutive days, and the sequencing of static and dynamic balance tests were randomized. Results were analyzed using the non-parametric one-way repeated Friedman test in SPSS version 18.0 (SPSS Inc., Chicago, IL, USA), and variable found to be significant were subjected to Wilcoxon post hoc testing.

RESULTS:

Static and dynamic balance showed significant difference at the three times assessments (test at 900, 1300, and 1700) during circadian. In the post hoc test of static (anteroposterior distance, mediolateral distance and COP (center of pressure) velocity) and dynamic balance (performance time), 1300 was the longer and faster than 900.

CONCLUSION:

These results indicated that control of postural balance is influenced by diurnal circadian rhythms, and confirm that control of postural balance is more effective and better performance in the 0900 hours than 1300 hours or 1700 hours.
