Nutritional monitoring of adolescent who are professional cyclists from Curitiba-Pr
Abstract
The physical exercise promotes increased energy expenditure in athletes and the physical training routine induces to considerable changes in nutritional needs. Adolescents begin professional sports practice early and need help to reach their nutritional goals, especially during training and competitions. This study aims to evaluate body composition, food intake and hydration of adolescent cyclists from the junior and youth categories, and perform nutritional interventions. Six professional teenager cyclists were evaluated in two steps regarding the anthropometric variables, dietary intake and hydration degree. Then interventions were made about the inadequacies found. Between the two evaluations the average intake of energy, carbohydrates and protein were 2390.95±325.19kcal/d, 5.08±2.0g/kg/d, 1.71±0.70g/kg, respectively. There was an average of 1.45±1.21% water loss between workouts and the average urine specific gravity was 1.005 g. ml-1at the end of training. The percentage of body fat estimated by the skin fold and by the bioelectrical impedance was respectively 9.39% and 10.56%, with no significant difference between the two methods. The results demonstrate inadequacies in carbohydrate intake and micronutrients. The study demonstrates the need for greater nutritional monitoring of athletes to ensure the health, recovery and maximum performance of adolescents.
