This work investigates human Walking to Running transition (WRT) and Running to Walking transition (RWT). The focus is to be able to identify the correct WRT and RWT phase jumps. This investigation uses experimental data from the VICON Motion Analysis System (MAS) and of the treadmill WRT and RWT trials. The musculoskeletal model consists of pelvis, femur, tibia, and foot. This investigation uses as reference the work reported in the literature by Diedricj and Warren.. For the calculations in this investigation Excel and Matlab are used to filter the data and calculate the relative phase jumps. This work reports the effects of experimental MAS capture frequency, and subject’s level of obesity, on WRT and RWT. Specifically, in order to investigate obesity, the subject’s experiments were conducted with no additional weight of the subject, additional weight of the subject of 5 Kg, 10 Kg, and 15Kg.
