Problem Statement: In the context of military modernization and competency-based educational reform, the physical fitness of students majoring in National Defense and Security Education (NDSE) at Ho Chi Minh City University of Education (HCMUE) plays a pivotal role in shaping the "teacher-soldier" persona. However, current evidence suggests that traditional physical education (PE) programs fail to meet the rigorous demands of specialized military activities, resulting in a low overall fitness compliance rate (48.1%) and a high injury prevalence (63,18%).

Approach: This study employed a pedagogical experimental design involving 100 students, divided into an Experimental Group (EG, n=50) utilizing a Circuit Training system and a Control Group (CG, n=50) following the existing curriculum. The exercises were selected based on the validation of 20 experts and experienced lecturers, focusing on stimulating the ATP-CP, Glycolytic, and Oxidative energy systems to induce a state of supercompensation.

Purpose: The primary objective was to establish a specialized "Pedagogical-Military" exercise system and evaluate the efficacy of the circuit training method in developing core physical qualities and adaptability to specialized military training intensities.

Results: Following a 10-week intervention, the EG demonstrated significant improvements (p < 0.01) across all six fitness assessments mandated by Decision 53/2008/ DECISION - MINISTRY OF EDUCATION AND TRAINING. The average growth rate (W%) for the EG reached 16.67% for males and 19.53% for females; notably, sit-up performance exhibited a sharp increase of 45.15% among female students. In contrast, the CG showed no significant changes (p > 0.05).
