BACKGROUND: The types of physical exertion undertaken by weightlifters and race walkers markedly differ. This difference should also be reflected in their respective diets. OBJECTIVES: The aim of the study was to investigate and assess the diets of professional weightlifters and race walkers, along with a comparison to the diets of those students studying physical education (PE). Materials and Methods. Subjects were respectively 12 weightlifters, 12 race walkers and 12 physical education students whose body composition and nutrition were determined by weighing the foods that were both eaten and drunk. RESULTS: The study groups showed body differences, which may have arisen through dietary differences. Higher calorie diets were observed for race walkers according to body mass whilst weightlifters showed no difference with the other groups. Dietary intakes of protein, fat, and carbohydrates were however inappropriate for all groups. Vitamin and mineral intakes in weightlifters and students were within tolerable limits, but the rather aggressive taking of supplements by race walkers resulted in standard/recommended consumption levels being greatly exceeded in some cases. CONCLUSIONS: The diets of the study groups of weightlifters and race walkers need to be corrected. KEY WORDS: nutrition in sport, weightlifting, race walking, food supplementation.
