Abstract Background Nutrition is vital for optimal physical performance; however, collegiate athletes have inadequate sports nutrition knowledge. Collegiate athletes also do not have dietary behaviors consistent with the recommendations of the United States Olympic Committee and the American College of Sports Medicine. This study aims to assess if a 6-week sports nutrition education intervention improves sports nutrition knowledge and/or dietary behaviors of NCAA Division 1 swimmers, and to determine if nutrition knowledge and dietary behaviors are correlated. Hypothesis Sports nutrition knowledge and dietary behavior will improve after a sports nutrition education intervention. Better sports nutrition knowledge will be correlated with better dietary habits. Methods Sports nutrition knowledge was assessed using a validated sports nutrition knowledge questionnaire developed by Torres-McGehee. Dietary behavior was assessed using a 3-day diet record. Diet records were analyzed for calorie, carbohydrate, protein, fat, zinc, iron, and calcium intake by the ESHA™ database. Dietary behavior was also assessed using a Fuel Zone Assessment, a tool developed by the authors, which measured why the athletes made food choices before or after 5 random practices during the intervention. Correlation between nutrient intake and nutrition knowledge was assessed using Spearman rho correlation. Males and females were analyzed separately. Results Twenty-three male and 22 female swimmers completed the sports nutrition questionnaires. Nutrition knowledge was significantly higher after the nutrition education intervention for both males and females. Mean score for males increased from 12.0±1.7 to 14.5±1.9 (p<0.05) on a 20 point scale, and female mean score increased from 11.7±2.3 to 13.8±2.0 (p=0.001) on the same scale. Five males and 10 females competed the 3-day food logs. Protein intake significantly increased for females following intervention (71-187g to 105-226g, p=0.03). No other measured nutrients significantly changed for males or female. No significant correlation was found between dietary intake and nutrition knowledge for any nutrient (p>0.05 for all nutrients). Fuel Zone Assessments indicate taste and carbohydrates are top factors for swimmers choosing foods pre-workout, and taste and protein are top factors for swimmers choosing foods post-workout. Conclusion College athletes should participate in sports nutrition education as part of their training to improve nutrition knowledge, but this study’s sample size was too small to make any conclusions regarding changes in dietary behaviors or correlation between nutrition knowledge and dietary behaviors.
