Abstract

University athletes operate within dual-performance environments that require simultaneous academic and athletic excellence. Nutrition plays a critical role in supporting both physiological performance and cognitive functioning; however, limited empirical work has examined its combined influence on athletic and academic outcomes within university athlete populations, particularly in low-resource contexts. This study aimed to investigate the relationship between nutritional practices, sports performance, and academic achievement among university athletes at the Eastern Technical University of Sierra Leone. It further sought to test an integrated model that positions cognitive functioning as a mediating pathway linking nutrition to overall performance outcomes. A cross-sectional mixed-methods design was employed, involving 150 athletes who completed structured questionnaires and 30 athletes who participated in semi-structured interviews. Quantitative data were analyzed using descriptive statistics, Pearson correlations, and multiple regression models, while qualitative interviews were examined through thematic analysis. The integration of both datasets strengthened the validity of findings. Findings revealed strong nutritional engagement, with 85 % of athletes consuming at least one balanced meal daily. Nutrition showed significant positive correlations with energy (r = 0.69), muscle recovery (r = 0.75), endurance (r = 0.72), academic focus (r = 0.63), memory retention (r = 0.58), and GPA (r = 0.65). Regression analyses indicated that nutritional quality significantly predicted both sports performance (β = 0.61, p <.001) and academic performance (β = 0.54, p <.01). Qualitative data highlighted nutrition’s central role in energy regulation, cognitive clarity, and performance consistency, alongside barriers such as time constraints and limited food access. The study provides robust evidence that nutrition is a key determinant of holistic performance among university athletes. Strengthening institutional nutrition support systems is essential for optimizing both athletic and academic success.
