While adolescent endurance runners are at risk for energy deficiency, limited studies have evaluated the effect of a nutrition education intervention. We evaluated the effect of a 4-week nutrition curriculum on adolescent cross-country runners’ nutrition knowledge, dietary behaviors, and self-efficacy to optimize intake of nutrient-dense carbohydrate foods, using a quasi-experimental, pretest-posttest design. Runners (n = 45; n = 26 F, n = 19 M; age 15.7 ± 0.2y) attended 4 weekly 30 to 60-minute lessons. Baseline body weight and composition were measured using bioelectrical impedance analysis. Paired samples t-tests measured difference in nutrition knowledge and self-efficacy scores, before and after each lesson. Mean nutrition knowledge scores significantly increased from pre- to post-test for lessons 1 and 2 (p < .001). Mean self-efficacy scores significantly improved pre- to post-test for all lessons (p < .001). Findings suggest a benefit of the curriculum to increase nutrition knowledge, self-efficacy, and support dietary behaviors promoting increase in nutrient-dense carbohydrate intake among adolescent runners.
