Introduction: Many studies indicated that sleep deprivation has several different effects on athletic performance.
However, there are controversies in findings and little attention has been on the interaction of sleep deprivation
with circadian rhythm. Purpose: The aim of this study was to investigate the effect of 4 hours of sleep
deprivation on indices of skill related physical fitness during morning and evening. Methodology: Twenty three
female collegiate athletic students with at least 2 years’ experience of regular participation in sport activities
(age: 21.47±0.73yr, height: 160.4±4.82 cm, weight: 56.25±1.07 kg) participated in this study voluntarily. Study
variables were measured during 4 testing sessions with one week interval. Measurements were performed after 8
hours sleep deprivation during morning (0:700-0:800) and evening (18:00-19:00). Measured study variables and
tests included neuromuscular coordination (stick test), reaction time (nelson test), balance (static balance test)
and agility (Illinois test). Results: Four hours of sleep deprivation induced negative effects on reaction time and
balance during morning (p=0.01 and 0.035 respectively). But did not cause significant effect on agility during
morning and evening (p>0.05). Conclusions: It was concluded that short-term sleep deprivation adversely
affects reaction time and balance in the morning.
