Abstract

Purpose: This research aims to analyze the influence of physical fitness and nutritional status on the Academic Performance Index (IP) of Level III Cadets from the 72nd Batch at the Indonesian Naval Academy (AAL). It employs a quantitative approach using multiple linear regression analysis. The study involved a sample of 150 cadets selected through random sampling, with data collected via physical fitness assessments, nutritional status evaluation using Body Mass Index (BMI), and IP data obtained from cadets' academic evaluations. Physical fitness demonstrates a positive and significant effect on the Academic Performance Index, with a significance value below 0.05. Nutritional status also exerts a positive and significant influence on IP, proving more dominant than physical fitness. Simultaneously, both variables significantly impact cadets' IP, as confirmed by the F-test with a significance level under 0.05. The coefficient of determination (R²) of 0.366 indicates that these independent variables explain 36.6% of the variation in IP, while the remainder is influenced by other factors beyond the study's scope. Physical fitness and nutritional status are critical determinants of AAL cadets' academic success. Integrated efforts in physical training and nutritional management are essential to enhance educational quality and cadet performance
