Background and Purpose: Physical fitness (PF) and sedentary lifestyles among adolescents have been extensively studied, but comprehensive research comparing differences in PF based on sedentary lifestyle levels remains limited. This study aims to analyze differences in PF based on sedentary lifestyle categories (low, moderate, and high) and compare PF between male and female adolescents. Methods: This comparative study used a one-way ANOVA design. A total of 90 adolescents (38 males, age 17.03±0.91 years; 52 females, age 16.94±1.07 years) were randomly recruited and classified into three sedentary lifestyle groups based on the results of measurements using the Adolescent Sedentary Activity Questionnaire (ASAQ): low (n1=30), moderate (n2=30), and high (n3=30). PF was measured using the Indonesian Physical Fitness Test for ages 16–19 years. Data analysis was performed using one-way ANOVA and Tukey’s post hoc test. Results: The results showed significant differences in PF scores between sedentary lifestyle groups (p=0.001), with the low sedentary lifestyle group having the highest PF score (mean=16.60) compared to the moderate (mean=14.30) and high (mean=10.40) sedentary groups. No significant difference was found between the PF of male and female adolescents (p=0.109). Conclusions: These findings confirm that a less sedentary lifestyle is associated with better PF in adolescents, while gender does not significantly affect PF levels. Therefore, strategies to reduce sedentary behavior need to be a primary focus in efforts to improve adolescent PF, particularly in Indonesia. © 2026 by the authors.
