Hello! My name is Junghyun and my Polygence project is on building an accessible, compact, and convinient gym equipment using electromagnetic induction. I chose to work on this project because I wanted gym experience to be more welcoming to beginners and those who are interested but have limited access to various types of gym equipment. After my project is complete, I would like to build up on my project to further nourish my interest in mechanical engineering involving sports science.

How to engineer better exercise equipment

Started Mar. 21, 2023

Abstract or project description

Exercise equipment is engineered with many different types of design criteria (ease of production, usability by people of differing sizes, comfort). However, is exercise equipment actually designed in a way that scientifically achieves the best outcome for the building and maintenance of muscle? This project will survey the design and effectiveness of different models of leg extension machines. The survey will consider how well the machines achieve particular outcomes for muscle physiology, such as tension applied to the muscle, how tension changes over time, muscle groups targeted, etc. These data will be combined with what is known about how different exercise routines affect muscle physiology. The results of this survey will then be used to design a leg extension machine that achieves optimal results for a given training objective. The goal of this project is to create an exercise machine that is optimally effective given the current state of knowledge in the fields of biomechanics and kinesiology.
