Abstract

|
Background: Hand grip strength (HGS) is used clinically with regards to rehabilitation and recommended as a basic measure in determining musculoskeletal function, weakness, and disability. The purpose of this study was to examine the relationship between sleep duration and muscle strength in Korean adults.
Methods: The Korea National Health and Nutrition Examination Survey (KNHANES) is a cohort survey investigating the health behavior, chronic disease prevalence, and food and nutrition intake statuses of the Korean population. We analyzed the association between sleep duration and hand grip strength by performing a logistic regression analysis on KNHANES data from 2014 to 2017. All statistical analyses were performed with SPSS and R tools.
Results: Among the 20,933 participants, compared to the group of patients who slept less than 5 hours a day, the group of patients who slept 6?7 hours had higher HGS, whereas the group of patients who slept more than 9 hours had weaker HGS. This trend was more apparent in the elderly population.
Conclusion: This study of the adult population of South Korea suggests that sleeping for approximately 6 to 7 h a day increases muscle strength and general well-being, whereas extreme sleep durations, such as less than 5 h or more than 9 h, result in weaker muscle strength, in general.
