Physical training must provide future officers optimal performance in the harsh scenarios typical of military operations. Understanding the behavior of strength as a physical capacity allows recognizing muscular conditions that enhance physical performance and defining possible musculoskeletal risk factors that cause injuries. OBJECTIVE: Evaluate the isokinetic strength of knee flexor and extensor muscles in students of the GJMC Military School at 60°/sec to determine absolute peak torque (aPT), symmetry (NS), and muscle balance (MB) according to body mass (BM) and muscle mass (MM). METHODOLOGY: A quantitative, descriptive, and cross-sectional study in a population (n) of 75 male students, on average aged between 19.76 ±1.35, evaluating strength using a Humac Norm isokinetic machine and body composition with a SECA mBCA 514 bioimpedance scale. RESULTS: Physical characteristics: height 1.73 ± 0.06m, bodyweight 67.4 ± 6.6, and muscle mass 43.75 ± 2.2 Kg. Descriptive values (mean and SD) of aPT extensors: right knee (RK) 178 ± 28.9, left knee (LK) 173 ± 31.23. aPT flexors: RK 109 ± 19.9, LK 102 ± 18.6 without significant differences. Peak extensor torque for BM: RK 2.6 ± 0.4, LK 1.63 ± 0.2 with a significant difference of p < 0.0001. Peak flexor torque for BM: RK 1.63 ± 0.2, LK 1.52 ± 0.24 with a significant difference of p 0.014; Peak extensor torque for MM: RK 6.07 ± 0.9, LK 3.73 ± 0.58 with a significant difference of p<0.0001. Peak flexor torque for MM: RK 3.73 ± 0.58, LK 3.46 ± 0.59 with a significant difference of p 0.0068. Knee extensor asymmetries: 9.72 ± 7.99%. Knee flexor asymmetries 9.00 ± 6.92 %. LK flexor-extensor muscle balance of 60.39 ± 10.33 %, and RK flexor-extensor muscle balance of 61.79 ± 8.27%. CONCLUSION: No significant differences were found in extensor and flexor peak torque values. The quadriceps/hamstring muscle balance was 1.4%, which is outside the risk of injury, maintains an adequate proportion between muscle groups, and trends positively towards the right leg expressed in significant differences for BM and MM. The asymmetry of flexors and extensors presented a difference of 0.72%, becoming a reference for the military population.
