Fasting and athletic performance studies reported pertormance aerobic capacity, measured by a VO 2 max test, remained unchanged after intermittent fasting in elite perforance and Metabolic rate calculatoras well as in well-trained long-distance and middle-distance runners.

In trained runnersthere was no effect on running time 10 kmlevel of perceived exertion or heart rate. Trained cyclists reported increased fatigue and muscle soreness during Ramadan, but this may be partly due to dehydration, since fluids are also restricted during this period when you cannot consume anything from sunrise to sunset.

In the context of fasting, low glycogen carbohydrate reserves may limit the execution of repeated, intense efforts. Active adults reported a decreased speed in repeated sprints after fasting 14 hours per day for three consecutive days. Active students reported decreased power and anaerobic capacity after ten days of intermittent fasting as assessed by the Wingate stationary bike test, although the study reported that power increased in the same group after four weeks.

Men and women who followed a strength training program had similar gains in muscle mass and strength when practising intermittent fasting compared to a control diet. There was no significant difference in muscle power between active men who did or did not practise intermittent fasting.

However, one study reported an increase in strength and muscular endurance in active young adults after eight weeks of strength training combined with intermittent fasting.

So, as we see, the results vary greatly from one study to another and are influenced by several factors, including the type of fasting and its duration, the level of the athletes, the type of sport they practise and so on.

In addition, very few studies have been carried out in women. Also, the lack of a control group in most studies means the effect of intermittent fasting cannot be isolated. So for the moment, it is not possible to draw a conclusion about the effectiveness of intermittent fasting on athletic performance.

Athletes who wish to use intermittent fasting should consider several practical issues before starting. Are their training schedules compatible with this dietary approach?

For example, does the period during which an athlete is allowed to eat allow them to consume enough food prior to doing physical exercise, or to be able to recover after the training? And, importantly, what about food quality, given that athletes must consume sufficient protein to recover and maintain their lean body mass and limit negative impacts on their performance?

Intermittent fasting may result in an energy deficiency that is too great for athletes with high energy needs to overcome.

This could be the case for endurance athletes running, cycling, cross-country skiing, triathlon, etc. due to their high volume of training.

These athletes may end up suffering from Relative energy deficiency in sport RED-Sa syndrome that affects hormone secretion, immunity, sleep and protein synthesis, among other things. It is also important to question the motivation for adopting a dietary practice as strict as intermittent fasting.

Some people do it for religious reasons such as Ramadan. A recent study showed a significant association between intermittent fasting in the past 12 months and eating disorder behaviours overeating, compulsive exercise, vomiting and laxative use.

Although this study does not determine whether fasting causes eating disorders, or eating disorders lead to fasting, it does highlight an associated risk in this practice. Finally, the potential impact of intermittent fasting on social interactions must also be considered.

A fasting schedule may limit participation in social activities that involve food. What is the risk of negatively influencing the eating behaviours of other family members, especially children or teenagers who see their parents abstain from eating and skip meals?

With such conflicting scientific data, it is not possible at this time to come to a conclusion about the effects of intermittent fasting on sports performance. Further studies are needed before this practice can be recommended, especially for seasoned athletes. Furthermore, the potential negative effects on other aspects of health, including eating habits and social interactions, are not negligible.

For these reasons, I was skeptical when I first learned of the intermittent fasting strategy that has gained some degree of popularity among endurance athletes.
