Are visual and auditory reaction times influenced by Ramadan fasting? Neuro performance study on healthy individuals

Aim: The purpose of this study is to find out whether visual and auditory reaction time (VRT and ART) is influenced by Ramadan fastingin healthy individuals in terms of neuro performance.Materials and Methods: 60 healthy individuals (30 male, 30 female) with the mean age of 20.22±1.45 years participated in the study.First reaction measurement was collected on the second week of the date Ramadan fasting started and this period was called fastingperiod. Second reaction measurement was collected five days after Ramadan fasting ended and this period was called post-fastingperiod. VRT and ART of the samples who participated in the study were made with reaction timer device. 10 trials for sound andlight stimuli were taken from each sample. The first five trials were considered as exercise and the average of the last five trials wasdetermined as reaction time. The analysis of VRT and ART in fasting and post-fasting periods was conducted with Wilcoxon matchedpairs test. In addition, Mann Whitney U test was used to analyze whether there were differences between fasting and post-fastingperiods of males and females in terms of VRT and ART.Results: No statistical difference was found between the VRT and ART of males and females in fasting and post-fasting period(p>0.05).Conclusion: In this study which examined the effect of fasting on VRT and ART, it was found that males and females who participatedin this study were not negatively influenced by Ramadan fasting in terms of neuro performance.
