Medial Tibial Stress Syndrome (MTSS) is one of the most-often reported and incapacitating pathologies in military personnel. Given that the muscles of the lower limb conduct an important task in attenuating impact forces when running and landing, deficiency and asymmetries in the neuromuscular function are associated with greater risk of having musculoskeletal injuries (MSI). Objective: the work sought to determine the risk factors for MTSS associated with the kinetics of the countermovement jump (CMJ) in cadets undergoing training. Methodology: a cohort of 164 cadets was monitored prospectively during 24 weeks. Upon starting the research, the study recorded the anthropometric and demographic data of the participants and inquired on some of their life habits and antecedents in using orthopedic material, injuries in lower limbs, and MTSS. Jump height (cm), eccentric deceleration of rate force development (EDRFD

Introduction.As in other military contexts, high incidence of injuries has been observed at Escuela Militar de Cadetes "General José María Córdova." Tibial stress has been observed in 4% to 10% of the military population during basic training. Resistance, strength, flexibility, and mobility are among the most important physical traits required for the new cadets' proper military training. Therefore, biomechanical evaluations are essential to monitor the neuromuscular system's maximum mechanical capacities; in this case, the lower limbs. The countermovement jump (CMJ) is among the most commonly used tests to indicate lower extremity muscle strength and anaerobic power. Objective. This study employs the countermovement jump test to characterize the lower limbs' neuromuscular component in the military population entering Escuela Militar de Cadetes. Materials and methods. A cross-sectional study was conducted on 63 first-level students (45 men and 18 women) from the military school in the second semester of 2017. Jump tests were measured by using two uniaxial force platforms (PASCO frequency of acquisition 1,000 Hz). The data was processed using ForceDekcs software. Results. Peak landing, concentric force, power, and eccentric deceleration were significantly higher (p value < 0.05) in men than in women. The
