“Introduction Most Muslims fast during the holy month of Ramadan from dawn till sunset, when they neither eat nor drink, as it forms one of the fundamental obligations of the Muslim faith [1]. The Ramadan month occurs eleven days earlier every year and thus over time may occur in any of the four seasons [2]. Therefore, the length of the daily fast during Ramadan varies from 11–18 hours in tropical countries [3]. Not only is the eating pattern by necessity altered during Ramadan, the type of food eaten during the night may also be different from that usually consumed during the rest of the year [4]. Energy and water intake are often reduced during this month [5, 6], which may result in reduced body mass [5, 6] and changed hydration status. Participants of Ramadan often maintain physical activity during the holy

month for recreation and health purposes, and this has the potential to further affect body mass and produce dehydration. The few learn more investigations that have examined the effect of Ramadan LY2109761 datasheet fasting on the hydration status of sportsmen report conflicting findings. For example, while urine osmolarity increased in Emirates soccer players [7] indicating a state of dehydration, the absence of change in urine specific gravity has been reported Branched chain aminotransferase in Turkish [8] and Tunisian [9] soccer players. Further, the interaction between participation in Ramadan and exercise and subsequent effects on circulating metabolites are also poorly understood. Resting

serum glucose has been reported to decrease during Ramadan in moderately trained runners [10], soccer and basketball players [11] and runners [12], but not to change in elite rugby players [5], weight lifters [13] and physically active men [1, 2]. Part of this conflict in findings may be due to the difference in time of the day, during which the training was conducted. For example, if the training was performed in the afternoon or early evening towards the latter part of the daily fast, the physiological stresses would be quite different to those if training was undertaken soon after breaking the fast. Certainly it is now well established that training after a 12 hour fast induces significantly different metabolic adaptations than training performed immediately after a meal [13]. Muslim athletes, including strength athletes, employ a variety of coping strategies to deal with the challenges of training and/or competing during the month of Ramadan [14, 15]. Some Muslim athletes train at night to prevent dehydration, hypoglycemia and possible decrements in performance.
