Ramadan is a period in which Muslims fast during daylight hours and is associated with disturbances in sleep-wake behaviour and adverse effects on physical and mental health in normal volunteers. Studies using athletes are rare and remain equivocal as to whether Ramadan influences sleep-wake patterns. Notably, the standardized assessment of subjective sleep quality and daytime sleepiness in athletes has not been established. This study employed the Arabic version of the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale in nine football players aged 20-35 years (mean +/- s: 26 +/- 4) one week before and during the last week of Ramadan. Compliance rates with self-administration were high (71%) and the results demonstrated a robust decline in total sleep time (before Ramadan: 6.6 +/- 2 h; at the end of Ramadan: 5.3 +/- 1 h; P<0.05, effect size 0.81). Compared with previous research, the study questionnaires offer improved methodology, including less time constraints plus standardization in scoring. Thus, this study demonstrates a framework for greater reproducibility and reliability in the assessment of subjective sleep-wake patterns in athletes before and during Ramadan.
