Abstract

This study aimed to examine the direct and indirect effects of physical activity, body mass index, and sleep quality on students’ physical fitness. This quantitative study used a path analysis design involving 85 students from SMA Pembangunan Laboratory, Padang State University. Physical fitness was measured using the Nusantara Student Fitness Test, physical activity using PAQ-A/GPAQ, body mass index through anthropometric measurement, and sleep quality using the Pittsburgh Sleep Quality Index. Physical activity significantly affected physical fitness (β = 0.352, p < 0.001), and sleep quality also had a significant effect (β = 0.353, p < 0.001). Body mass index showed no significant effect (β = −0.026, p = 0.786). The model explained 30.4% of physical fitness variance. Physical activity and sleep quality are key determinants of students’ physical fitness.
