Ramadan fasting in SOCCER

ISSPF Article

During the ninth month of the Muslim year, a strict fasting from sunrise to sunset is performed. Within this period of Ramadan, Muslim athletes and soccer players are no different & also abstain from eating and drinking from dawn to sunset.

During May 2018 the UEFA Champions League Final contesting both CF Real Madrid & Liverpool FC coincided with the holy month of Ramadan. Within the Liverpool team that season, it contained Mohammed Salah, along with Liverpool teammates Sadio Mane and Emre Can, as well as Real Madrid’s Karim Benzema and Achraf Hakimi. Some reports have discussed around this time the big decision these players will have had to make on whether to refrain completely from eating and drinking on the day of the final – and subsequently influence their personal performance strategies.

Salah, who set a Premier League record number of goals during that season, had always been strict to adhere to the Ramadan period in his career, however, in the 48hrs build-up to the UEFA Champions League Final 2018, it was suggested he cleverly added a level of flexibility with his nutritional strategies in order to fuel correctly for one of the world’s biggest competition whilst continue with the Ramadan process.

Although several studies & research have been conducted on athletes to determine the effects of Ramadan fasting in terms of physical preparation, fitness and performance, there is little data or reports available regarding the knowledge, beliefs and attitudes of soccer players and performance coaching understanding towards Ramadan fasting during high-level competitions. 

Do we as a coach or performance coach understand the issues our players might be facing during this Ramadan period?

ISSPF faculty member, Professor Karim Chamari, is seen as one of the leading researchers & world renowned experts in the area of Ramadan fasting in soccer and the effects of intermittent-fasting in general has outlined some key thoughts to tackle this area.

Chamari and colleagues in this area of research & performance have professed how physical performance during a competitive 90-min soccer match among trained Muslim players was adversely affected by Ramadan fasting. These findings were shown through a deterioration of physical performance as early as in the 1st half of match-play. These are huge implications not only for the individual player from a health & wellbeing perspective, but also performance and injury risk wise

Furthermore, researchers in the area of Ramadan fasting in soccer have also reported:

  1. Higher levels of fatigue late during match
  2. Acute depletion of muscle glycogen to critical levels
  3. Severe dehydration and physical fatigue

The above-mentioned adaptations in soccer players drinking, sleep patterns, and energy/food reserves will probably impact not only the performance side in terms of training and match play, but additionally the recovery of the player or athlete post-training or games. In fact, the recovery process of after training or games is highly variable and depends on several factors but are mainly related to glycogen, or energy reduction or depletion, sleep loss, and dehydration.

Are we prepared as a coach to assist them, advise them, understand their possible lack of energy, poor training and match performance levels, change in personality traits due to lack of food and fluid, lack of sleep. How do we alter their training routines or compensate for this phase in their careers to reduce the risk of injury? Do we manage their training load through this period

What are the issues?

One of the main components in athletic or soccer performance is the provision of proper fuelling and hydration techniques, so this becomes an issue to players during this Ramadan phase. Available literature has suggested Muslim soccer players participating through this period may face performance decrements as a result of:

  • Changes in circadian or bodily rhythms
  • Changes in sleep patterns
  • Duration of sleep
  • Reduction in blood glucose or energy levels
  • Reduced daytime fluid intake and subsequent dehydration
  • Injury


All these issues discussed are then resultant in a more rapid onset of fatigue/tiredness and increased incidence of non-contact and overuse injury within the game and sport in general.

TOP TIPS for athletes during Ramadan

Some leading researchers and practitioners have suggested that if compelled to play a competitive match during the month of Ramadan, it is important that players:

  • Rehearse dietary fasted states throughout the normal training period rather than initiating on competition days
  • Playing a friendly match in a simulated Ramadan fasted state if more than 1-2 players in the squad following Ramadan e. This allow the player to get accustomed both physiologically & psychologically
  • Pre-training & pre-match strategies such as mouth-rinsing…make the body think energy is available!
  • Remember to educate your players, coaches and family members about the physiological and psychological effects of Ramadan fasting!


What are the experts in Ramadan fasting in soccer saying?

The importance of education sessions to help players to better manage Ramadan intermittent fasting and sports participation is paramount…. furthermore, some players, despite having good knowledge about the influence of Ramadan fasting on sleep, and potentially on football performance, still intended to observe fasting due to their religious commitment.

Farooq et al., (2016)
