The spring-mass system is a simple physics problem that has been widely discussed due to its importance and wide applications in different problems, particularly the waist-legs-feet system of a person could be represented by a spring-mass model, and the leap of a person can also be represented by the compression-release phenomena of the spring-mass system previously mentioned, this phenomenon is of great importance in different areas such as human health, and robotics. Thus, a model of damped spring-mass with a deformable load cell platform was used for getting a characteristic Green’s Function of a vertical jump of a person.
