Tibial stress fractures are a common occupational injury suffered by military personnel. Yet, it is unknown if the body borne load military personnel commonly carry during operational activities increases tibial compression and risk of stress fracture. This study sought to examine how tibial compression is affected by body borne load and speed of locomotion. Up to 16 participants will have tibial compression force quantified while they walk (1.3 m/s), jog (3.0 m/s), and run (4.5 m/s) with three body borne loads (0, 15 and 30 kg). Tibial compressive force will be quantified with custom Matlab code and submitted to RM ANOVA to test main and interaction effects of load (0, 15, and 30 kg) and speed (1.3, 3.0 and 4.5 m/s). Peak tibial compression is expected to significantly increase with each incremental increase of locomotion speed and body borne load. Understanding how tibial compressive force changes during common military operational activities will produce the military the knowledge to decrease the number of tibial stress fractures suffered by military personnel.
