“…In agreement with other studies (Ramadan 2002;Karli et al 2007;Brisswalter et al 2011;Aziz et al 2012), we found no significant changes in body mass and composition during Ramadan. Conversely, several studies have reported significant reduction in body mass during Ramadan fasting (Bigard et al 1998;Bouhlel et al 2006;Ziaee et al 2006;Chaouachi et al 2008;Chennaoui et al 2009), while others showed significant mass gain during the month of Ramadan (Frost and Pirani 1987;Yucel et al 2004;Siddiqui et al 2005).…”

“…This latter study showed significant increases in absolute and relative peak power during Ramadan, with no reduction in mean power, fatigue index, and change in lactate kinetics compared with the preRamadan tests. Likewise, Aziz et al (2012) showed that aerobic and anaerobic adaptations to a high-intensity training program were not adversely affected by RIF, possibly because the overall training intensity and nutrient intake were maintained throughout the Ramadan period. Other studies have shown a reduction in muscular performances during the month of Ramadan (Chtourou et al 2012a,b).…”

“…In fact, the effects of RIF on body mass and composition vary among different studies. Some works reported a reduction in body mass during Ramadan fasting (Bigard et al 1998;Bouhlel et al 2006;Ziaee et al 2006;Chaouachi et al 2008;Chennaoui et al 2009), while other ones reported no significant changes (Ramadan 2002;Karli et al 2007;Brisswalter et al 2011;Aziz et al 2012). Conversely, several studies have reported significant mass gain during the month of Ramadan (Frost and Pirani 1987;Yucel et al 2004;Siddiqui et al 2005).…”

“…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.…”

BackgroundMuslim bodybuilders often continue training during Ramadan. However, the effect of resistance training in a fasted versus a fed state during Ramadan on body composition and metabolic parameters in bodybuilders is not well known. The aim of this study was to evaluate the effects of resistance training in a fasted versus a fed state during Ramadan on body composition and metabolic parameters in bodybuilders.MethodsSixteen men were allocated to two groups: Eight practicing resistance training in the late afternoon in a fasted state (FAST), and eight training in the late evening in an acutely fed state (FED) during Ramadan. All visited the laboratory in the morning two days before the start of Ramadan (Bef-R) and on the 29th day of Ramadan (End-R) for anthropometric measurement, completion of a dietary questionnaire, and provision of fasting blood and urine samples.ResultsBody mass and body fat percentage remained unchanged in FAST and FED during the whole period of the investigation. Both FAST and FED experienced an increase in the following parameters from Bef-R to End-R: urine specific gravity (1%; p = 0.028, p = 0.004 respectively), serum concentrations of urea (4%, p = 0.006; 7%, p = 0.004 respectively), creatinine (5%, p = 0.015; 6%, p = 0.04 respectively), uric acid (17%; p < 0.001, p = 0.04 respectively), sodium (1%; p = 0.029, p = 0.019 respectively), chloride (2%; p = 0.039, p = 0.004 respectively), and high-density lipoprotein cholesterol (11%, p = 0.04; 10%, p = 0.04 respectively).ConclusionHypertrophic training in a fasted or in a fed state during Ramadan does not affect body mass and body composition of bodybuilders. Additionally, Ramadan fasting induced changes in urinary and some biochemical parameters, but these changes were not different according to when the training occurred.

“…The duration of this ritual of worshipping is 1 month every year and involves the limitation of food and liquid intake between sunrise and sunset [2,3]. Since the Islamic calendar is a lunar calendar and it is 10 days shorter than a solar calendar, the month of Ramadan arrives 10 days earlier every year.…”

Abstract:Objective: Our aim was to determine how Ramadan fasting eff ects serum Human NAD-dependent deacetylase sirtuin 1 (SIRT1/ SIR2L1) and visfatin levels during pregnancy. Materials and methods: Thirty-six patients were included in this case-control study. The patient group consisted of 18 pregnant women who were Ramadan fasting. Another healthy 18 pregnant women with matching pregnancy weeks and ages formed the control group. Blood samples were obtained from the patients for biochemical analyses and serum adipokine level measurements. Results: The mean sirtuin and visfatin levels in fasting pregnant women were 2.87 ± 0.95 and 60.18 ± 19.49 ng/mL, respectively, while the mean serum sirtuin and visfatin levels in the control group was determined to be 4.28 ± 1.45 and 23.26 ± 6.18 ng/mL, respectively. A statistically signifi cant diff erence was determined between the groups (p = 0.002, p = 0.0001). A correlation analysis provided a negative correlation between number of fasting days and sirtuin levels (r = 0.45, p = 0.005) and a positive correlation with visfatin levels (r = 0.73, p = 0.0001). Conclusion: As a result, while the serum sirtuin 1 level of pregnant women decreased due to fasting in Ramadan, we determined that their visfatin levels increased and this increase was in correlation with the days of fasting.
