Food consumption evaluation before and after judo competition

Abstract

Introduction: Judo is a sport which has as characteristics high intensity and short duration. A well-balanced diet with proper caloric input and appropriate nutrients distribution are mandatory for the good performance during practices and competitions. Studies show that judokas lose weight rapidly before their matches through, amongst other methods, restrictive diets. Objective: Evaluate the dietary consumption before and after judo competition. Materials and methods: The dietary consumption of thirteen competitive judokas, of both genders, was assessed during the twenty four hours prior the weighting and the twenty four hours period that succeeded the match. After the sample collection, the data was inserted in the supporting nutrition program (Nutwin - Unifesp) for the calories and macronutrients calculation. Results: In the pre-competitive period, the average caloric value was 369 kcal, given that two athletes were under complete hydrological and alimentary restriction. The average macronutrient consumption prior the weighting was 0,9, 0,4 and 0,2 g/kg, and after the match was 5,1 1,9 and 1,5 g/kg, related to carbohydrate, protein and lipids, respectively. There has been a high variation between the individuals. Conclusion: The athletes were submitted to a severe alimentary restriction on all the macronutrients prior the weighting. After the match the majority of them had low carbohydrate consumption and an increased protein and lipids consumptions. Given that the athletes take part in a wide range of competitions during the year, those strategies may increase the risk of nutritional deficiency and excesses, with consequences regarding the teenager development and growth.
