“…The absence of changes in body mass and composition can be explained by our findings which identified a decline in daily training duration and intensity and the reduced exercise caloric expenditure which resulted in a comparable energy availability value. This result was in agreement with results from previous studies that reported no change in body mass during Ramadan fasting when comparable energy availability values were maintained ( 31 , 35 ). Additionally, Mujika ( 36 ) suggested that athletes and trained subjects could maintain their lean body mass and muscular strength after reducing training loads.…”

A distance runner's performance is generally limited by energy availability when competing or training. Modifying meal frequency and timing by abstaining from eating or drinking, from dawn to dusk, during Ramadan fasting is hypothesized to induce hypohydration and reduced caloric and nutrient intake. The purpose of this study was to investigate the impact of Ramadan fasting on runners' performances. Fifteen trained male distance runners who observed Ramadan participated in this study (Age = 23.9 ± 3.1 years; Peak VO2 = 71.1 ± 3.4 ml/kg/min). Each participant reported to the human performance lab on two testing occasions (pre-Ramadan and the last week of Ramadan). In each visit, participants performed a graded exercise test on the treadmill (Conconi protocol) and their VO2, Heart Rate, time to exhaustion, RPE, and running speed were recorded. Detailed anthropometrics, food records, and exercise logs were kept for the entire period of the study. Repeated measure ANOVA, paired t-test, and Cohen's effect size analysis were carried out. Results indicated no significant influence for Ramadan fasting on body mass (p = 0.201), body fat (p = 0.488), lean body mass (p = 0.525), VO2max (p = 0.960), energy availability (p = 0.137), and protein intake (p = 0.124). However, carbohydrate (p = 0.026), lipid (p = 0.009), water (p < 0.001), and caloric intakes (p = 0.002) were significantly reduced during Ramadan Fasting. Daily training duration (p < 0.001) and exercise energy expenditure (p = 0.001) were also reduced after Ramadan. Time to exhaustion (p = 0.049), and maximal running speed (p = 0.048) were improved. Overall, time to exhaustion and maximal running speed of the distance runners was improved during Ramadan fasting, independent of changes in nutrients intake observed during the current study. With proper modulation of training, distance runners performance can be maintained or even slightly improved following the month of Ramadan fasting.

“…They found no significant difference in mean HR (P = 0.03) between groups when comparing Ramadan and 1 month after Ramadan for small-sided games. This study indicated that RF combined with small-sided games and repeated-sprint ability training has no significant effect on most aerobic and anaerobic performances in male senior basketball players Bataineh et al [77] examined the effects of carbohydrate mouth rinsing during RF on running time to exhaustion and on peak treadmill speed. The study concluded that carbohydrate mouth rinsing improves running time to exhaustion and peak treadmill speed under RF conditions.…”

Invited Review introduCtionRamadan fasting (RF) is practiced by adult Muslims during the 9 th lunar month every year. It entails that they abstain from eating and drinking between dawn and sunset. Medical and religious scholars got closer in their approach to advice given to patients based on objective risk assessment. [1] Muslim patients with acute or chronic medical conditions may be exempted from fasting; many do still choose to observe the fast sometimes against medical advice. This may adversely affect their health if not addressed properly by evidence-based recommendations. [2] There has been a tremendous recent interest in the health implications of RF. Keeping up with developments in this area may prove difficult, and hence, a narrative overview under a single cover may be particularly useful in presenting a digest of the research and expert opinion in the year. [3] Our previous review of the literature published in 2017 was the most viewed Introduction: There has been an increased interest in health implications of Ramadan fasting (RF). Materials and Methods: This is a narrative, nonsystematic review of the literature including all relevant full articles in English in three electronic databases (Scopus, PubMed, and Google Scholar). The search term "Ramadan fasting" was used to identify the relevant records to provide a readily comprehensible concise account of the contributions made to research and clinical practice in 1 year (2018). Results: The publications spanned basic, clinical, ethical, professional, and cultural and advocacy facets of the subject. The publications crossed the conventional disciplinary lines and geographical locations and appeared in journals with varying systems of access. Only full-text research articles in English were reviewed. Review articles, news, note items, and correspondence were not included. No formal bibliometric analysis is presented. Emerging concepts are presented under the relevant subheading depending on the available literature. Impact of RF on diabetes control, pregnancy outcome and fetal life, and sports and athletes' well-being received somewhat more prominent coverage by research work published in 2018. Renovascular disease, and risk factors, posttransplant care, and some metabolic concerns for patients with hepatic, renal, and metabolic conditions were covered too. Patterns of use of emergency services during Ramadan and features of some specific medical emergencies were examined by some workers. Most interesting perhaps was the greater focus on documenting the perception, attitudes, and practices of both patients and healthcare professions regarding deciding and acting during Ramadan. Isolated research reports addressed subjects of wide nature from body composition and energy metabolism to smoking, law, music, and history. Conclusions: The volume of scholarly work on Ramadan fasting and health remains modest. Greater improvements in both quality and quantity of research on Ramadan are needed. Most studies indicate that Ramadan fasting is safe in mild and st...

“…En cuanto a volumen e intensidad de la carga se sabe que esta no siempre logra reflejar mejoras producto de que el rendimiento físico también es modulado por diversos principios del entrenamiento, además del componente cognitivo que puede generar mejoras independientemente de los cambios fisiológicos relacionados a la intensidad y volumen de la carga (Clarke, Hammond, Kornilios y Mundy 2017;Fuentes-Barría et al, 2020). Por otro lado, se sabe que un volumen de carga hasta el agotamiento o pruebas de extenuación no son muy efectivas producto de la transición generada desde el metabolismo glucolítico a lipídico como sustrato energético principal (Bataineh et al, 2018;Bavaresco Gambassi et al, 2019). Del mismo modo, entre las principales limitaciones de los diversos protocolos de enjuagues bucales con CHO se ha descrito a la demanda energética asociada a la intensidad y la tolerancia a la ingesta durante el ejercicio, siendo los protocolos que involucran un periodo prolongado de la solución al interior de la cavidad bucal los que pueden ocasionar molestias gastrointestinales o vómitos dificultando el proceso de inspiración y expiración (Ali, Moss, Yoo, Wilkinson y Breier, 2017;Pires et al, 2018).…”

Objetivo; Analizar los efectos del enjuague bucal con carbohidratos en deportistas. Material y Métodos; Se realizó una búsqueda en la revista Retos, además de Medline / PubMed, Web of Science, Springer, Scopus, Europe PMC, SPOLIT, SPORTDiscus, SciELO, Epistemonikos y Trip database. Las búsquedas se realizaron entre los años 2018 y 2022 utilizando la estrategia “carbohydrate AND mouth rinse AND sports”, seleccionándose solo revisiones sistemáticas con metaanálisis. Resultados; Se identificaron 318 registros de los cuales luego de aplicar los criterios de elegibilidad se analizaron tres, cuyos resultados mostraron posibles mejoras sobre la potencia media de salida (Diferencia media estandarizada (DME) = 0,25, IC 95%; 0,04 a 0,46), rendimiento deportivo (DME = 0,15, IC 95%; 0,04 a 0,27) y la resistencia muscular hasta el fallo (Diferencia media (DM) = 1,24, IC 95%; 0,70 a 1,77), mientras que el tiempo contrarreloj (DME = -0,13, IC 95; -0,36 a 0,10) y la fuerza máxima muscular (DM = 0,25, IC 95%; -1,81 a 2,32) no muestran mejoras significativas. Conclusión; La suministración de un protocolo de enjuagues bucales con carbohidratos en forma constante puede constituir una ayuda ergogénica. Sin embargo, estos efectos aún son controvertidos. Palabras clave: Suplementos dietético; carbohidratos; enjuague bucal; rendimiento deportivo; medicina deportiva. Abstract. Objective; To analyze the effects of mouthwash with carbohydrates in athletes. Material and methods; A search was carried out in the journal Retos, in addition to Medline / PubMed, Web of Science, Springer, Scopus, Europe PMC, SPOLIT, SPORTDiscus, SciELO, Epistemonikos and Trip database. The searches were carried out between the years 2018 and 2022 using the strategy "carbohydrates AND mouthwash AND sports", selecting only systematic reviews with meta-analysis. Results; 318 records were identified, of which after applying the eligibility criteria, three were analyzed, which results showed possible improvements on the mean power output (Standardized Mean Difference (SMD) = 0.25, 95% CI; 0.04 to 0 .46), athletic performance (SMD = 0.15, 95% CI, 0.04 to 0.27), and muscular endurance to failure (Mean Difference (MD) = 1.24, 95% CI, 0.70 to 1.77), while time trial (SMD = -0.13, 95% CI; -0.36 to 0.10) and maximum muscle strength (MD = 0.25, 95% CI; -1, 81 to 2.32) does not show significant improvements. Conclution; The administration of a protocol of mouth rinses with carbohydrates in a constant way could constitute an ergogenic aid. However, these effects are still controversial. Keywords: Dietary supplements; carbohydrates; mouthwashes; athletic performance; sports medicine.
