Abstract
Objective: Sleepiness caused by sleep deprivation may increase the risk of injuries and damages during physical activity. Individual data so far indicate a generally better static postural stability of women regardless of sleeping conditions. The main aim of this study was to assess the impact of sleep deprivation on postural stability according to gender after 24 h of sleep deprivation. Methods: Participants included 83 students (36 men and 47 women). Postural stability was measured with eyes open and closed eyes before and after sleep deprivation. Data from posturographic platform were used to assess postural stability objectively. Results: The type of test determined the size of observed changes in postural stability. The data suggest that women are better able to cope with the effects of sleep deprivation than men. Conclusion: Postural control system is very important in sport and in physically active people. The results show that men are more sensitive to sleep deprivation than women because they had higher COP (center of pressure) values in tests. Less postural stability of the body due to sleep deprivation indicates a higher risk of injury during physical activity.
Highlights
Stable posture is a motor skill that allows to maintain and restore the body balance in any position
An increase in the COP path length in the open eye test after sleep deprivation was only recorded in men in the experimental group, and this indicates less stable postural control of men after a sleepless night
Not all aspects have been clarified, we believe that the results presented in this study make an important contribution to the study of the effects of sleep deprivation on postural stability and may constitute an important step in the development of future research in this direction
Summary
Stable posture is a motor skill that allows to maintain and restore the body balance in any position. Postural stability is a determinant of functional independence and plays an important role in the daily routine. Good stable posture is essential for practicing physical activities. The prerequisite for maintaining a stable posture is primarily the proper functioning of vestibular, somatosensory, and visual systems. The lack of integration of one of these systems may lead to reduced postural stability [1]. Postural control in most activities of daily living, such as standing, is well trained, but for more complicated activities, it requires other resources to be activated
