📄 Research Paper Abstract
Below is the abstract from this arXiv research paper. Mathematical notation has been simplified for readability.
We theoretically investigate the biomechanical aspects of Olympic weightlifting within the framework of optimal control theory. The squared force and the rate of force development (RFD) defined by the time derivative of the force are taken into account in the evaluation functions of the first and second pull phases of the snatch motion. Focusing on the vertical trajectory of the barbell, we develop a minimal model to describe the mechanical characteristics of the weightlifting exercise. The calculated barbell trajectory agrees well with the experimental data obtained by video analysis. Our study would be useful for the further development of mathematical models for weightlifting motions and related exercises.
