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
