AI Thread Summary
The discussion invites math, physics, and engineering enthusiasts who are also runners to collaborate on understanding running performance using the Spring Mass (SM) Model. This model conceptualizes a runner as a mass on spring-like legs, akin to pogo sticks, and has been validated through several research papers. Participants with knowledge of Newton’s and Euler’s equations, Kunge-Kutta methods, and Lagrangian mechanics are encouraged to reach out for collaboration. Additionally, a user from Brazil expresses interest in using a gait cycle image for their physiotherapy thesis but encounters access issues. The conversation highlights a blend of biomechanics and academic collaboration in running performance analysis.

Looking for math/physics people interested in the running biomechanics

Are there any other math/physics/engineering runners out there who are interested in collaborating on an effort to understand their own running performance by using a mathematical model known as the Spring Mass (SM) Model (1). It treats the runner as a single mass bouncing on a pair of spring-like legs, similar to pogo sticks (2). There have been a few papers verifying the model and demonstrating that it does model a runner’s performance.

If you have a mathematical background, understand Newton’s and Euler’s equations, know a little bit about Kunge-Kutta and have some understanding of the Langrangian formulation and equations of motion, please send me an email at tjacmc@aol.com. It might be interesting to see what insights we can come up with together.

hey
i live in brazil and I'm doing a theses in physiotherapy and i would like to use your picture of gait cycle, if you don't mind. but i can't get it open! if you can, please send me! i wouldn't know how to thank you
see you soon!
love,
julia
