The month-long diurnal Ramadan fast imposes a major challenge to Islamic athletes. Sporting events are programmed throughout the year, with the result that training and competition are often scheduled during Ramadan. The small numbers of well-controlled studies that have examined the effects of Ramadan on athletic performance suggest that few aspects of physical fitness are negatively affected, and only modest decrements are observed. Whereas subjective feelings of fatigue and other mood…

The effects of Ramadan intermittent fasting on athletic performance: Recommendations for the maintenance of physical fitness

Current evidence from good, well-controlled research supports the conclusion that athletes who maintain their total energy and macronutrient intake, training load, body composition, and sleep length and quality are unlikely to suffer any substantial decrements in performance during Ramadan.

Effects of Ramadan Fasting on Health and Athletic Performance

The available data indicate that high-level athletes who maintain their training load and control their sleep, food, and fluid intake and therefore do not undergo body composition changes, could sustain their performance during Ramadan.

Sport participation and Ramadan observance: Advice for the athlete

Competitors in most events can observe Ramadan with a small loss of athletic performance, however, intermittent fasting can endanger health for individuals with type I diabetes mellitus, and for participants in ultra-endurance events (particularly under hot conditions).

Achieving optimum sports performance during Ramadan: Some practical recommendations

The available evidence indicates that high-level athletes can maintain performance during Ramadan if physical training, food and fluid intake, and sleep are appropriate and well controlled, and athletes should ensure adequate sleep throughout Ramadan.

Ramadan and Sport: Minimizing Effects Upon the Observant Athlete

The intermittent fasting of Ramadan could affect various aspects of body physiology and biochemistry important to athletic success, andLogical measures to minimize the effects of Ramadan include the optimization of mood state, maintenance of training, minimization of sleep loss, appropriate adjustments of diet, and the monitoring of competitors for chronic dehydration.

The Impact of Ramadan Observance upon Athletic Performance

Empirical data on the extent of changes in anaerobic effort, endurance performance and muscle strength might be anticipated from the decrease in muscle glycogen and body fluid reserves are considered, suggesting potential nutritional and behavioral tactics for minimizing such effects in the Muslim competitor.

Strategies for maintaining fitness and performance during Ramadan

Science can help coaches improve their training plans and educate players with respect to the challenges presented by Ramadan to all levels of sports participation.

In most of the situations studied to date, Ramadan observance has had only limited adverse consequences for either training or competitive performance, and more information is needed on responses in situations where protein intake is likely to be inadequate and when vigorous muscle training is in progress.

Effect of Ramadan Fasting on Body Composition and Physical Performance in Female Athletes

It is found that Ramadan fasting could affect the body composition, but not physical performance in female athletes during Ramadan.

Effects of Ramadan Fasting on Perceived Exercise Intensity during High-Intensity Interval Training in Elite Youth Soccer Players

There was no adverse effect of fasting on perceived exercise intensity in Ramadan fasted players, and also no impact on their maximal aerobic performance post-Ramadan.



Lipid profiles of judo athletes during Ramadan.

The present results show that the combination of the change in diet pattern during Ramadan, along with intense exercise training, induced a significant decrease in body mass associated with a reduction in body fat and changes in some of the serum lipids and lipoproteins.

Impact of Ramadan on physical performance in professional soccer players

The phase shift of food intake and disruption of sleep patterns affect actual and perceived physical performance in Islamic athletes and Islamic athletes need to explore strategies that will maximise performance during Ramadan.

Influence of Ramadan fasting on physiological and performance variables in football players: Summary of the F-MARC 2006 Ramadan fasting study

Abstract The timing of food and liquid intake depends on the times of sunset and sunrise during the month of Ramadan. The current body of knowledge presents contradicting results as to the effect of

The influence of Ramadan on physical performance measures in young Muslim footballers

Ramadan had little effect on objective tests of physical performance in this sample of youth players observing Ramadan, most likely due to the effects of training and familiarity with the test methods.

A balance diet with high content of carbon hydrates is recommended to prevent hypoglycaemia that affects the health of fasting sportsman training for resistance.

The effect of the Ramadan fast on physical performance and dietary habits in adolescent soccer players

It is indicated that Ramadan fasting can lead to a significant decrease in athletic performance capacities, and the decrease in performance does not necessarily relate to changes in caloric intake and sleeping hours during the fast.

Haematological, inflammatory, and immunological responses in elite judo athletes maintaining high training loads during Ramadan.

The results suggest that athletes who continue to train intensely during Ramadan are liable to experience a myriad of small fluctuations in hormones, immunoglobulins, antioxidants, and inflammatory responses.

Effect of Ramadan Intermittent Fasting on Aerobic and Anaerobic Performance and Perception of Fatigue in Male Elite Judo Athletes

The results show that the RIF has little effect on aerobic performance and on very short duration sprinting and jumping test performance in elite Judokas, and experienced athletes can maintain both sufficient energy intake and normal training loads during the R IF.

Effects on health of fluid restriction during fasting in Ramadan

Common findings of the studies reviewed were increased irritability and incidences of headaches with sleep deprivation and lassitude prevalent, and a reduction in drug compliance was an inherent negative aspect of the fast.
