Objective  The present study aims to measure the incidence of overload injuries in training soldiers, who are subjected to intense physical exercise, and to compare it with a control group. Next, it intends to verify whether there is any relationship between overload injuries and some neuromuscular function parameters. Methods  Analytical, prospective observational study. Both the observational and the control group consisted of soldiers from the Portuguese Army. Clinical evaluation was performed by medical interview in the week prior to the beginning of a military parachuting course and in the week immediately after its completion. The neuromuscular performance was assessed by isokinetic dynamometry during the medical interview. Results  With 44 of the 57 military personnel in training complaining of pain, the observational group had significantly more injuries than the control group ( p < 0.001). Five complaints had traumatic origin and 39 were overload injuries. Of the 39 military personnel with overload injuries, 21 reported limited sports performance. However, isokinetic dynamometry showed no statistically significant differences in neuromuscular performance ( p  = 0.223 and p  = 0.229). Conclusion  Military personnel in training are prone to overload injuries, with an incidence rate > 70%. The implementation of strategies for injury monitoring and prevention is critical to promote health and physical capacity.
