The aim of this study was to examine characteristics between nutrient intakes, body composition and physical fitness in gifted athletic boys. The subjects were conducted in 50 boys aged 9～12 years living in Busan, Ulsan and Gyeongsangnam-do, Korea. Dietary intake information was collected from participants using 3-day food recorded and body composition was measured by bioelectrical impedance analysis, and their anthropometric parameters were measured. Swimming group"s daily energy intakes were significantly higher compared to those of other groups. Athletics and swimming groups were significantly taller than gymnastics. Swimming group was significantly higher than gymnastics group in weight, fat mass, body fat percent and lean body mass. Athletics and swimming groups were significantly longer than gymnastics group in sit and ball throwing. Swimming group was significantly better than other groups in sit up, and athletics group was significantly faster than gymnastics group in 50 m run. In correlation result for nutrient intake and body composition: 1) Body weight shows positive correlation with protein, phosphorus, sodium, vitamin B1, C and niacin. BMI shows positive correlation with sodium and niacin. Fat mass shows positive correlation with niacin and folate. Body fat% shows positive correlation with vitamin C, E, niacin and folate. LBM shows positive correlation with allelements except lipid, calcium, vitamin A, C, E and folate. In correlation result for nutrient intake and physical fitness: 2) Push up shows positive correlation with iron and vitamin C. Sit and throw ball shows positive correlation with the events except lipid, fiber, vitamin A, E and folate. Sit up shows positive correlation with vitamin B₁. Half squat shows positive correlation with iron. Standing long jump shows positive correlation with total energy, lipid, and vitamin A, B and B₂. Long run shows negative correlation with protein, carbohydrate, fiber, phosphorus, iron, sodium and zinc. Side step shows positive correlation with niacin. Sit and reach shows negative correlation with total energy, carbohydrate, phosphorus, sodium, zinc and vitamin B₂. In correlation result for body composition and physical fitness: 3) Sit and throw ball shows positive correlation with body weight, BMI, fat mass, body fat% and LBM. Standing long jump shows positive correlation with LBM. But long run and 50 m run shows negative correlation with body weight and LBM.
