Abstract: The human body is a dynamic system subjected to impact. It is represented by 15 spring–mass–damper model. Both linear and non-linear analysis of the model has been carried out. A square wave impact of various magnitude (t = 0.1 s) has been applied at the human shoes to study the response of lumbar spine. The variation of response due to alteration of shoes stiffness and damping has also been investigated.

Keywords: human body modelling; repetitive impact; parameters; lumbar spine; vibrations; human shoes; shoe stiffness; shoe damping; vertical jumping; musculoskeletal stress; biomechanics; biomedical engineering.
