Objective: to determine the level of macronutrient intake of Congolese athletes practicing endurance race in relation to their performances.
Methodology: Our study was prospective and conducted in Brazzaville over a period of 14 days, from February 14 to 28, 2017. Twenty-nine (29) mid-distance athletes and nineteen (19) riders High-level backgrounds and males participated in the study. A questionnaire consisting of recording what each athlete ate for seven (7) consecutive days in three periods of the day: morning, noon and evening had been distributed. The quantities of food consumed had to be increased by using the principles of the household units (cup, tablespoon, and plate), pieces (sugar, meat, chicken leg, vegetable, cassava etc.) and to name the foods consumed. The “weekly diary” method (Cubeau J., Pequinot G, 1980) was applied to determine the amount and nature of food consumed by athletes. Results: The energy intake of carbohydrate was 2074.81Kcal, or 518.704 ± 68.60g with a percentage of 80.90% in middle distance runners (MDR) and 2420.6 Kcal, or 605.15 ± 37.82g with a percentage of 68.17% for long distance runners (LDR). While the lipid intake was 356.54Kcal, or 39.22 ± 4.43g with a percentage of 6.12% in MDR and 543.27Kcal, or 59.76 ± 3.67g with a percentage of 6.73% in the LDR. On the other hand, the protein intake was 332.49Kcal, or 83.12 ± 8.89g with a percentage of 12.96% in the MDR and 25.09% in the LDR. Conclusion: The feeding behavior of Congolese endurance runners(ER) does not meet the standards of nutritional balance recommended by modern nutritionists and therefore has a negative effect in athlete’s performance.
