Abstract
Introduction: The aim of this study was to investigate the Effect of 30 hours sleep deprivation on shooting score and corticospinal excitability of thenar eminence muscle in soldiers.
Methodology: For this purpose, 11 volunteers (male) with an average height of 185 and an average age of 20 years,After passing on the research entry (sleep quality, general health level and sports medicine history), were selected from a military training center; After doing ethical protocols. Methodology of the study performed in two stages, using Transcranial magnetic stimulation technique by Medtronic device as well as to register the shooting score by air rifle before and after 30 hours of sleep deprivation, the subjects were studied. Obtained data, with descriptive and inferential statistics using SPSS (Statistical package for social science) software version 16 and by taking 5% of measurement error, were analyzed.
Results: It was shown that 30 hours of sleep deprivation caused a significant decrease in shooting score (p=0.003); also 30 hours of sleep deprivation caused a significantly increased the range of motor evoked potential (MEP) amplitude (p=0.009), no significant reduction of MEP latency (p=0.98) and no significant increase in facilitated MEP latency (p=0.15) measured in the thenar of subjects.
Discussion: According to the results of this study it can be concluded that 30 hours of sleep deprivation, significantly decreased the score of shooting, probably because of disturbances in corticospinal excitability following sleep disorders. In other words we can say that probably standing fatigue central nervous system which reduces the shooting score after sleep deprivation, can be associated with disturbances in the neuronal excitability Be. Which can be explore in future research.
