“…Lotfi et al [ 45 ] reported findings for soccer players and runners, and results for the two disciplines were thus considered as independent studies. Similar findings in terms of mean ± SD of body mass were reported in Zarrouk et al [ 51 , 52 ], and only one data of Zarrouk et al [ 52 ] was considered for analysis. From before to the first week of Ramadan, body mass did not change in five studies [ 43 , 45 , 48 , 49 , 52 ], decreased in one study [ 50 ] and increased in another study [ 45 ].…”

“…The training characteristics of the included studies is presented in Table S3: body mass data were reported in eight studies [41][42][43][44][45][46][47][48][49][50][51][52] (Table S4) and body composition data were reported in seven studies [41,[46][47][48][49][50][51] (Table S5). Güvenç [48] used a foot-to-foot bioelectric impedance analyzer and the remaining studies [41,46,[48][49][50][51] used a skinfold caliper to assess body fat content, whilst Meckel et al [42] reported only the total sum of skinfold thickness; the results of this study were not included in the analysis.…”

Effects of Ramadan Observance on Dietary Intake and Body Composition of Adolescent Athletes: Systematic Review and Meta-Analysis

et al. 2020

To evaluate the effects of Ramadan observance on dietary intake, body mass and body composition of adolescent athletes (design: systematic review and meta-analysis; data sources: PubMed and Web of Science; eligibility criteria for selecting studies: single-group, pre-post, with or without control-group studies, conducted in athletes aged <19 years, training at least 3 times/week, and published in any language before 12 February 2020). Studies assessing body mass and/or body composition and/or dietary intake were deemed eligible. The methodological quality was assessed using ‘QualSyst’. Of the twelve selected articles evaluating body mass and/or body composition, one was of strong quality and eleven were rated as moderate. Ten articles evaluated dietary intake; four were rated as strong and the remaining moderate in quality. Continuation of training during Ramadan did not change body mass from before to the first week (trivial effect size (ES) = −0.011, p = 0.899) or from before to the fourth week of Ramadan (trivial ES = 0.069, p = 0.277). Additionally, Ramadan observance did not change body fat content from before to the first week (trivial ES = −0.005, p = 0.947) and from before to the fourth week of Ramadan (trivial ES = -0.057, p = 0.947). Lean body mass remained unchanged from before to the fourth week of Ramadan (trivial ES = −0.025, p = 0.876). Dietary data showed the intake of energy (small ES = -0.272, p = 0.182), fat (trivial ES = 0.044, p = 0.842), protein (trivial ES = 0.069, p = 0.720), carbohydrate (trivial ES = 0.075, p = 0.606) and water (trivial ES = −0.115, p = 0.624) remained essentially unchanged during as compared to before Ramadan. Continued training of adolescent athletes at least three times/week during Ramadan observance has no effect on body mass, body composition or dietary intake.

“…9 Therefore, it is a religious obligation for all healthy adult Muslims to fast during Ramadan. 2,10,11 However, while fulfilling this obligation, Muslims are faced with some changes in their eating and drinking habits, hydration conditions, and in performing physical and mental activities because of their lifestyles on the basis of fasting in Ramadan. 12 These changes cause a number of problems such as fatigue and affect one's general performance negatively.…”

The purpose of this study was to evaluate the effect of Ramadan fasting on fatigue in nurses. The study was conducted between June 19 and July 27, 2014, with a descriptive design. This study was completed with 99 nurses working in a public hospital in the city of Gaziantep located in the Southeastern Anatolia Region of Turkey. The data of the study were collected by using a questionnaire and the Piper Fatigue Scale. The Piper Fatigue Scale includes 4 subscale/dimensional scores and total fatigue scores. Higher scores indicate more fatigue. Statistical significance levels were set at P < .05. It was determined that the fatigue subscale and total mean scores of nurses increased in a statistically significant manner except for the affective subscale after the month of Ramadan (P < .05). In addition, it was found that the fatigue mean scores of those, who were working for 0 to 4 years, were employed in surgery units, and evaluated their health as bad, were higher (P > .05). The Ramadan fasting increased fatigue levels of nurses. Therefore, it is of vital importance to evaluate fatigue levels of nurses especially in the month of Ramadan and take the necessary precautions in terms of patient and personnel safety.

“…In youth soccer players, Güvenç (39) reported that peak running distance, time, and velocity recorded during the 20 m shuttle run test were not adversely affected by Ramadan observance. In Karate players, during Ramadan, Zarrouk et al (52) reported that maximal voluntary contraction (MVC) of the knee extensors and time to exhaustion at 75% of MVC were not adversely affected by Ramadan observance. Conversely, in soccer players, Kirkendall et al (53) showed that agility time during the 4-line agility test, 7 × 30 m repeated sprint time, counter-movement jump height, 10 m sprint time, and the running distance during a 20 m multistage shuttle run test were greater during in comparison with before Ramadan.…”

Teenage students continue to participate in physical education lessons during the month of Ramadan. The combination of intermittent fasting and physical activity may result in impairment in both physical and cognitive performances. Additionally, dietary intake, sleep and hydration status may be negatively affected. To counteract the possible negative effects of intermittent fasting upon health and athletic performance of adolescent students, some practical recommendations should be outlined including (i) nutrition and sleep education of students, (ii) reducing the intensity and increasing the recovery periods during physical education lessons and (iii) practicing physical education in indoor. Additionally, teachers should be aware of clinical signs and symptoms of dehydration and hypoglycemia.
