“…However, many studies show that athletes from different countries, ages, and sports do not consume diets in line with these nutritional recommendations 5,34 . Several factors can explain this dichotomy: results of new studies that lead to changes in the recommendations do not always reach athletes quickly; often athletes follow information disseminated through social networks and media or by unqualified colleagues and professionals 35 , which creates a nutritional cacophony.…”

From a historical perspective of athletes' eating practices, the advancement of science and the provision of food in the modern Olympic Games, the author seeks to show that many challenges in practicing Sports Nutrition have their roots in how these processes were built. This essay aims to provide arguments for a reflection on the work of dietitians in the sports' scenario considering the growth of interest in this area, as well as the hosting of major sports events in Brazil. The professional training and the skills required to work in this area, as well as the eating practices of athletes, often far from the nutritional recommendations but heavily laden with symbolism and representations, making it important for their identity within their peer group, are among the current challenges that can be emphasized. As the main prospects for the comprehensive care of athletes, the author highlights the importance of adopting an interdisciplinary approach, and of dietitians fully understanding the meaning of nutrition for athletes in order to address the gap between their food practices and the recommendations.

“…If we consider the recommendation for the UM, earlier described intakes are different, many of them do not reach even half of it [22,30]. Two studies are characterized by their percentage of intake [38,39] where the percentages are among the 21 ranges, 4-32%.…”

The ultramarathon is defined as an event whose distance is greater than a marathon. It requires not only a preparation on the endurance performance, but also of other more specific qualities such as orientation and climbing. This type of event has a minimum duration of 5 h up to 22 consecutive days or more. These characteristics influence in the preponderance of the energy system and consequently which nutrients will be necessary to intake and increase in order to replace them.The adequate nutritional planning is a fundamental tool to optimize the athlete's performance, replenishing nutrients and electrolytes and reducing fatigue during exerciseThe aim of the review is to determine dietary guidelines in continuous ultramarathons. The energy, macronutrient, vitamin, and mineral requirements will be increased according to the intensity and duration of the ultramarathon. The energy expenditure ranges from 350-650 kcal/h, determining a negative balance. The role of carbohydrates for its rapid energy replenishment and the role of lipids for multi-day events are distinguished. The recommendation of carbohydrates is 7-12 g/kg in order to achieve muscle glycogen repletion. Protein intake is 1.2-1.7 g/kg to prevent muscle damage and/or used it as an energy source in case of a poor energy supply. Hydration is crucial in prolonged events and especially in warm environments.Once the systematic review of nutritional guidelines in continuous ultra-marathon events has been performed, it has been found that athletes fail to meet nutritional and water recommendations. The cause of this fact is multifactorial (e.g., high energy depletions, inability to carry the totality of food with them, tiredness of the same flavors, hot environmental conditions..), but mainly due to gastrointestinal discomfort and lack of appetite. It is important to provide runners with not only accurate nutritional guidelines, but the correct way to accomplish them to finish the event and to prevent episodes that compromise their health.

Nutrient Intake by Ultramarathon Runners: Can They Meet Recommendations?

Abstract: Sports nutrition recommendations for the habitual diet were not achieved. During a competition day, a large variation was found in nutrient intake; this may be related to a high incidence of GI distress.
