Introduction: Most youth do not meet national nutrition recommendations and overconsume high-calorie, low nutrient-dense foods. There are many nutrition-related interventions targeting school-aged youth; however, these programs have shown mixed results regarding effectiveness. Youth sports provide an alternative means for delivering nutrition-based education. Coaches have been identified as a main source of information for youth athletes, however, most coaches do not possess adequate nutrition knowledge to provide recommendations. Purpose: 1) Determine the effects of a six-lesson, coach-facilitated nutrition intervention on improving knowledge, behaviors, and self-efficacy (SE) related to general and sport-specific nutrition practices, 2) determine coach knowledge and SE of nutrition related behaviors for young athletes, and 3) examine implementation strategies of participating coaches. Methods: Athletes, 13-18-year-old (N = 143), and coaches (N = 13) from mid-Michigan were recruited and randomized by team into either a nutrition education group (NE; n = 70) or a mental skills control group (MS; n=73). Coaches received a 90-minute training on delivering the intervention and delivered two lessons per week for three weeks. Athletes completed a pretest and posttest assessing knowledge, SE, and general (GN) and sport-specific (SN) nutrition behaviors, including food group consumption, hydration practices, and sport supplement use. Coaches completed a pretest and posttest assessing level of knowledge and SE related to general and sport-specific nutrition recommendations. Coaches also completed a process evaluation after each lesson, assessing reach, dose delivered, dose received, use of videos (treatment group only), and overall rating of each lesson provided. Mixed-model ANOVA, controlling for age, gender, and sport, was used to determine differences between athletes in the NE group and MS group and mixed-model ANOVA was used to determine differences between coaches in the NE group and MS group. Significance was set at p<0.05. Results: A total of 89 athletes (NE: n=36; MS: n = 53) and 10 coaches (NE; n = 5; MS; n = 5) completed pre- and posttest assessments. Results revealed significant improvements among athletes in the NE group compared to the MS group in SS nutrition knowledge (F(1,83) = 4.89, p = 0.03, Np2 = 0.06) SS nutrition knowledge SE (F(1,83) = 5.10, p = 0.03, Np2 = 0.06), GN knowledge SE (F(1,84) = 8.44, p = 0.005, Np2 = 0.09) and total WG consumption (F(1,84) = 4.52, p = 0.04, Np2 = 0.05). The proportion of coaches meeting requirements for adequate knowledge (i.e. ≥ 80% correct) was higher in the NE group for SS knowledge (20% pretest vs. 80% posttest) compared to the MS group (0% pretest vs. 20% posttest), but was found to be non-significant (z = 1.29, p = 0.20). A significant increase in GN knowledge SE among the treatment group coaches (t(4) = -2.73, p = 0.05) and improvements in SE related to SS nutrition knowledge were approaching significance (p = 0.10). Coaches followed the intervention protocol as intended. Average attendance during the 6-lesson series was 77% for the NE group and 71% for the MS group. Conclusion: A six-lesson nutrition intervention can improve nutrition knowledge, behaviors and SE in adolescent athletes and may improve nutrition knowledge and SE in coaches. Results from the current research study can also help inform best practices for delivering nutrition education to young athletes. Future studies should include larger samples and assess social ecological factors that impact nutrition behaviors, including food choices, access, and availability.
