GRIJOTA PEREZ, Francisco Javier et al. Nutritional analysis in long and middle distance athletes during a sport season. Nutr. Hosp. [online]. 2016, vol.33, n.5, pp.1136-1141. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.578.

Objective: The main objective of this study was to analyze the nutritional intake of high-level athletes specialties in long and middle distance during an athletic season to identify possible deficiencies. Methods: To carry out the study, we proceeded to assess the diet and different intake levels of macronutrients (carbohydrates, fat and proteins); and changes that occur in the concentration of these elements were analyzed 4 different times of the season: at baseline and at 3, 6 and 9 months of training. The sample consisted of a group of 23 elite endurance athletes with a minimum of 5 years of training, a weekly charge between 14-20 hours, and an average of 100-120 miles a week. The procedure consisted of nutritional register for a period of three consecutive days in the 4 different moments of the season. Results: The results show significant increases (p < 0,05) in protein intake between 3-9 months. Conclusion: Nutritional intake in endurance athletes increases throughout the athletic season, with lower intake in macronutrients than recommended by the scientific community, and increases in protein intake during periods of spring and summer, according to competition periods.
