“…This is most likely due to learning effects, which are also documented in other studies (Tian et al 2011, Lotfi et al 2010, Doniger and Simos 2006, Halyburton et al 2007. Halyburton et al (2007) also found a practise effect for the Digit Span Backward test, albeit significantly smaller than the time effect in our study.…”

“…Participants in the study by Tian et al (2011) had better reaction times during the second half of Ramadan (P<0.01) at the identification task of the CogState test (11). Dolu et al (2007) found that concentration of medical students at the Mesulam and Weintraum Cancellation Tasks was lower during the first week Ramadan, with less targets marked and more targets missed (P<0.01) (10).…”

“…Two studies found a slower reaction speed during the first week of Ramadan (Roky et al 2004, Dolu et al 2007, while measurements in the second half of Ramadan showed no effect on reaction speed (Roky et al 2000, Tian et al 2011. Information processing speed and concentration were decreased in the first week of Ramadan in one study (Roky et al 2004), but were better than normal in another study (Lotfi et al 2010).…”

Background -During Ramadan, Muslims refrain from eating and drinking from dawn until sunset. In 2012, Ramadan took place during summer, with fasting periods up to 19 hours. Previous studies have reported delays in sleeping and waking time and consequently decreased daytime alertness. Nevertheless, data on the effects of Ramadan on neuroperformance are scarce. Aims -We investigated the impact of Ramadan on tiredness and neuroperformance in Belgian Muslims.Methods -20 Subjects were tested outside of Ramadan, halfway through Ramadan and in the last week of Ramadan. Tiredness was assessed with the Fatigue Assessment Scale (FAS) and alertness with the Stanford Sleepiness Scale (SSS). Neuroperformance was tested with the simple reaction time for reaction time (REA-t) and concentration (REA-sd), symbol digit substitution for visual perception (SDS), digit span backwards for short term memory (DSB) and hand-eye coordination test (EYE).Results -Ramadan had no effect on FAS. SSS increased during Ramadan, but remained within normal physiological boundaries. There was no significant effect on REA-t and SDS. Ramadan had beneficiary effects on REA-sd, DSB and EYE. There were no correlations between FAS or SSS and other neuroperformance parameters.Conclusion -Daytime sleepiness moderately increases during Ramadan. Neuroperformance remains mostly unaffected. Concentration improved during Ramadan, but we observed are large interindividual differences.

“…sleep disturbances, general fatigue, and impairment of cognitive functions (Kadri et al, 2000;Leiper et al, 2003;Tian et al, 2012). Research related to Ramadan and performance in Malaysia have been helpful in understanding how Ramadan fasting affects sports performance (see Aziz & Weileen, 2008;Roy et al, 2011a;Roy et al, 2011b;Singh et al, 2011).…”

The article examines the influence of socio-cultural practices of Ramadan fasting in competitive sports and adaptation pathway of the athletes. The study describes how the socio-cultural context acts as the social "panopticon" and explains the adaptation pathways among Muslim archers. Foucauldian concept explains individual actions and behaviors within social and cultural settings, and adaptation pathways during Ramadan fasting. Eleven elite Malaysian Muslim archers participated in an open ended interview to identify individual experiences of competing in high level sports while engaging in Ramadan fasting. Relevant quotes were extracted to identify means and methods leading to a pathway toward adaptation. The inductively identified pathway viz. understanding of the context, control and adjustment, willpower and self enhancement, belonging and gravitating, trust and support culminates in the dimension of adaptation. The study highlights how cultural and societal influences have a bearing on actions, behaviors, and decisions of competitive athletes.
