I. ULUSLARARASI FİZİKSEL AKTİVİTE, BESLENME VE SAĞLIK KONGRESİ 1 st INTERNATIONAL PHYSICAL ACTIVITY, NUTRITION AND HEALTH CONGRESS P12 Effect of Sleep Deprivation on Reaction Time and Agility Hasan Mohammadzadeh 1 , Mandana Heydari 2 1 Department of Motor Behavior, Urmia University, Urmia, Iran 2 Department of Physical Education, Peyam Noor University, Urmia, Iran Aim: One of the important human basic needs is sleep. Even a one and a half hours of sleeplessness can be reduced to 32% in individual consciousness. In the area of physical activity and sport, the level of effect of sleep deprivation on performance are depend factors such as time and type of deprivation and the type and complexity of the task (3) (Riley 1990) (1).

The purpose of this study was to determine the effect of partial and overall sleep deprivation on reaction time and agility of male high school students. Methods: The 15 mail Student voluntarily choose to justify and after obtaining consent participated in the study. Data collection tools including Nelson ruler test to measure reaction time and Illinois agility. Measure was distance type. Subjects on three alternating e nights of sleep in terms of normal, full and partial sleep deprivation have been completed reaction time and agility tests. The (ANOVA repeated measures) and paired t test were used data analysis. Results: Results showed on averages of triple agility, reaction time tests differences are seen. In term of reaction time, differences between normal sleep and both partial and overall sleep deprivation were significant. On the other hand, in agility test, just differences between normal sleep and overall sleep deprivation groups were significant. Conclusion: These findings conforms the results of Scott (2006) (3. Water House (1988) & et all found that the effect of sleep deprivation on reaction time of drivers. The Maximum effect observes by over thirty hours deprivation.
