This study aimed to describe the physique characteristics and competition nutrient intake of professional Rugby League players and to assess use of a statistical technique for evaluating validity of dietary reporting. Players (n = 74) were endomorphic mesomorphs and had a mean weight, height, and BMI of 93.4 ± 10.9 kg, 179.9 ± 7.3 cm, and 28.5 ± 2.1 kg/m2 respectively. Mean sum of eight skinfolds was 78.9 ± 2.2 mm (12.4 ± 2.9% fat). Players (n = 34) reported a mean daily energy intake of 17,708 ± 3,688 kJ (carbohydrate 51%, protein 18%, fat 25%, alcohol 4%) with 6 and 2.0 g · kg−1 · d−1 from carbohydrate and protein respectively. Micronutrient intake was adequate but alcohol consumption was high relative to health standards. The dietary records provided a plausible estimate of energy intake however further research is required to evaluate statistical techniques for assessing dietary validity in athlete groups.
