Study aim: The purpose of this research was to examine the effects of different times of day on static and dynamic balance performance.
Material and methods: Thirty male individuals (age 22 ± 1.2 years, BMI 23.4 ± 1.3 kg/m2, height 178.5 ± 6.52 cm) volunteered for the study. The participants performed static and dynamic balance tests at 10:00, 15:00, and 20:00. Static and dynamic balance were measured using Y Balance Test (YBT) and the Balance Error Scoring System (BESS). One-factor repeated measures ANOVA with the LSD post-hoc procedure was performed to examine balance changes in the morning, afternoon, and evening.
Results: Results indicated a significant difference in static balance scores at different times of day (p < 0.05). Post-hoc analysis indicates that mean of errors in afternoon exhibits significantly smaller than those of morning (p = 0.024), and evening (p = 0.029). Other results showed significant differences in dynamic balance at different times of day (p < 0.05). Post-hoc analysis indicates that means of reaching distance in afternoon exhibits significantly larger than those of morning (p = 0.032), and evening (p = 0.026).
Conclusions: The results provide strong evidence about the effect of different times of day on performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
