Abstract Summary
To better understand the effects of fatigue on running biomechanics, data were collected using an inertial measurement unit (IMU) for 28 subjects running a marathon race. During one marathon, however, one male recreational runner sustained a running-related injury in his left calf muscle and retired near the 28-km mark. In this case study, we use a composite index to characterize subject-specific ‘typical’ running patterns for the injured runner at the beginning of the race and detect ‘atypical’ patterns that may have been indicative of injury.
