Abstract
The current study investigated the association between sports nutrition knowledge and dietary quality in a sample of adult Irish male hurling players. Nutrition knowledge was measured by the validated Sports Nutrition Knowledge Questionnaire (SNKQ). Diet quality was measured by the Australian Recommended Food Score (ARFS) calculated from food frequency questionnaire data. Analysis of variance and linear modelling were used to assess associations between variables. A total of 265 (129 elite, 136 sub-elite) players were recruited. No significant difference in nutrition knowledge (SNKQ) was found between groups. Results showed a significant difference (p = 0.02; d = 0.39 ± 0.25; small) in food score (ARFS) between groups. A weak, positive association (r = 0.3, p = 0.007) was found between nutrition knowledge and food score. Elite level players, aged 28–32, with college degrees, that have previously received nutritional guidance displayed the highest levels of both nutrition knowledge and food score. Higher levels of nutrition knowledge and food score were expected in elite players, however were only found in food score. Nutrition knowledge does contribute to dietary quality although future interventions should focus on specific gaps in knowledge such as how to meet total energy/carbohydrate requirements.
