UNLABELLED There is little information about the actual nutrition and fluid intake habits and gastrointestinal (GI) symptoms of athletes during endurance events. PURPOSE This study aimed to quantify and characterize energy, nutrient, and fluid intakes during endurance competitions and investigate associations with GI symptoms. METHOD A total of 221 endurance athletes (male and female) were recruited from two Ironman triathlons (IM Hawaii and IM GER), a half-Ironman (IM 70.3), a MARATHON, a… 

Figures and Tables from this paper

Carbohydrate-Dependent, Exercise-Induced Gastrointestinal Distress

TLDR
Training the gut with high intake of CHO may increase absorption capacity and probably prevent GI distress, and CHO mouth rinse may be a good strategy to enhance performance without using GI tract in exercises lasting less than an hour.

Ultra-endurance athletes' food choices, nutrition knowledge and strategies to improve dietary intake and performance

TLDR
The aims of this thesis were to explore the challenges to optimal nutritional intake, establish whether a gut-training programme could enable ultra-endurance athletes to meet the CHO recommendations and determine whether a short term high fat, low CHO diet (HFLC) or a low fat, high CHO (LFHC) diet prior to competition is more effective for ultra- endurance performance, when fuel availability is likely to be compromised.

Nutrient Intake by Ultramarathon Runners: Can They Meet Recommendations?

TLDR
Sports nutrition recommendations for the habitual diet were not achieved during a training period and on a competition day; a large variation was found in nutrient intake; this may be related to a high incidence of GI distress.

Low FODMAP: A Preliminary Strategy to Reduce Gastrointestinal Distress in Athletes

TLDR
Preliminary findings suggest that short-term FODMAP reduction may be a beneficial intervention to minimize daily GI symptoms in runners with exercise-related GI distress.

Carbohydrate Intake Practices and Determinants of Food Choices During Training in Recreational, Amateur, and Professional Endurance Athletes: A Survey Analysis

TLDR
Large-scale survey findings suggest a preference of endurance participants’ CHO intake during training in liquid form independent of exercise intensities and offer novel insights into CHO intake practices to guide sports nutrition strategies and education.

Validity of a Food and Fluid Exercise Questionnaire for Macronutrient Intake during Exercise against Observations

TLDR
Even though FFEQ overestimates the energy and carbohydrate intake, it is still a useful tool for ranking individuals based on their intake, and accurately estimates the fluid intake on a group level during competitions in recreational athletes.

Energy, macronutrient and water intake during a mountain ultramarathon event: The influence of distance

TLDR
The majority of the participants in the study present low carbohydrate intakes, however, fluid intake seems to be adequate, and different distances did not significantly influence the participants’ nutritional strategies.

Energy balance, macronutrient intake, and hydration status during a 1,230 km ultra-endurance bike marathon.

TLDR
The results show that participants failed to maintain in energy balance and that CHO and fluid intake dropped below recommended values during the second half of the bike marathon, which may be necessary to improve eating and drinking behavior during prolonged ultra-endurance exercise.

No Effects of a Short-Term Gluten-free Diet on Performance in Nonceliac Athletes.

TLDR
A short-term GFD had no overall effect on performance, GI symptoms, well-being, and a select indicator of intestinal injury or inflammatory markers in nonceliac endurance athletes.

Gastrointestinal Function, Damage and Symptoms During Exercise and the Potential Therapeutic Role of Probiotic Supplementation

TLDR
Investigating the relationship between markers of GI permeability and damage, measured in the blood, and GI symptoms during endurance exercise, up to marathon distance running implies that a moderate prevalence of GI symptoms exists in recreational runners, with 27-58% of marathon participants having reported mild to severeGI symptoms during the race.

Gastrointestinal problems as a function of carbohydrate supplements and mode of exercise.

TLDR
Examination of prevalence and duration/seriousness of gastrointestinal (GI) problems as a function of carbohydrate-rich (CHO) supplements and mode of exercise revealed significant relationships between nausea and urge to defecate, between an urge to defy, GI cramps and flatulence, and between belching and side ache.

Food Intake and Electrolyte Status of Ultramarathoners Competing in Extreme Heat

TLDR
The rate of fluid intake was greater in finishers than in non-finishers, and finishers tended to more nearly meet their energy needs, which is consistent with fluid overload during a running event lasting more than 24 hours in hot and humid conditions.

Nutritional practices of male cyclists before and during an ultraendurance event.

TLDR
Although most cyclists failed to meet recommended prerace CHO intakes, most achieved the recommended CHO intakes during the race.

Nutritional intake during a 244 km multisport ultraendurance race

Data about the nutrition during ultraendurance competitions are scarce, with the exceptions of few case reports. Because very long lasting sports events become more and more popular, we aimed to

Study on food intake and energy expenditure during extreme sustained exercise: the Tour de France.

TLDR
The strategy of intake of large quantities of CHO-rich liquids seems to be the appropriate answer to maintain energy and fluid balance under these extreme conditions.

Nutritional Considerations in Triathlon

TLDR
Although mild endotoxaemia may occur after an Ironman-distance triathlon, this does not seem to be related to the incidence of GI problems, and post-exercise rehydration is best achieved by consuming beverages that have a high sodium content in a volume equivalent to 150% of body mass loss.

Gastrointestinal symptoms in long-distance runners, cyclists, and triathletes: prevalence, medication, and etiology

TLDR
In general, exercise-related GI symptoms were significantly related to the occurrence of GI symptoms during nonexercise periods, age, gender, diet, and years of training.

The effect of two sports drinks and water on GI complaints and performance during an 18-km run.

TLDR
It is concluded that sports drinks used during an 18-km run in cool environmental conditions do not support the performance better than mineral water and addition of caffeine to the sports drink has no effect on either running performance or GI complaints.

Superior endurance performance with ingestion of multiple transportable carbohydrates.

TLDR
Ingestion ofGF led to an 8% improvement in cycling time-trial performance compared with ingestion of G, suggesting that GF led to a sparing of endogenous CHO stores, because GF has been shown to have a greater exogenous CHO oxidation than G.

The effect of carbohydrate gels on gastrointestinal tolerance during a 16-km run.

TLDR
Despite high CHO gel intake, and regardless of the blend (GLU vs. GLU+FRC), average scores for GI symptoms were at the low end of the scale, indicating predominantly good tolerance during a 16-km run, Nevertheless, some runners experienced serious problems, and individualized feeding strategies might be required.
