Diseño de Prototipo de Prótesis de Miembro Superior para Práctica de Halterofilia de Crossfit

CrossFit® in people with a upper limb disability is a challenge in designing elements for weight lifting above the head due to: fixation, carrying capacity and safety. This paper presents a proposal for the design of a prosthesis prototype for CrossFit® weightlifting practice with wrist disarticulation, based on the product design methodology of Ulrich and Eppinger, including detailed design through Finite Element Analysis (FEA) and tensile failure test in a load system INSTRON® 5582. The results show from the mechanical point of view that the design allows the lifting of loads up to 2000N.Keywords: Prosthesis, upper limb disability, CrossFit®, weightlifting.
