Abstract :
Abstract:Sleep is one of the basic human needs that is regulated by homeostatic and circadian processes. The aim of this research is the effect of 24 hours of sleep deprivation on reaction time, working memory and attention in college students. The statistical population of the research is all male students of Islamic Azad University, Babol branch. 180 male students who were between 19 and 25 years old volunteered (available sampling) to cooperate with the present research; Among them, 64 people were selected as a statistical sample after initial screenings. The subjects were randomly divided into two control (n=32) and experimental (n=32) groups. The experimental group experienced 24 hours of sleep deprivation. Then from both groups simple and selective reaction time tests, working memory (N-back=1,2) and attention. In order to analyze the data, analysis of covariance and one-way ANCOVA statistical method were used. The results showed that 24 hours of sleep deprivation had no effect on simple and selective retrieval time, working memory (1-back) and selective attention, but there was a significant decrease on working memory (2-back) and divided and sustained attention. Therefore, it can be said that sleep deprivation has a negative effect on some components related to sports performance and causes a decline in sports performance.
