Effect of 30 hours sleep deprivation on shooting score and corticospinal excitability in soldiers

To investigate the Effect of 30 hours sleep deprivation on shooting score and corticospinal excitability of Thenar eminence muscle in soldiers. For this purpose, 11 volunteers (male) were selected from a military training center.

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 software version 16 and by taking 5% of measurement error, were analyzed

it was shown that 30 hours of sleep deprivation caused a significant decrease in shooting score (p=0 /003); also 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.

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. Which can be explore in future research
