This research aims to analyze the dynamic strength of athletes' punches and kicks using digital sansak equipped with sensors. The objective is to optimize athlete training in sports that rely on striking power by providing detailed insights into the stress and deformation experienced by the digital sansak. The methodology involves a simulation study where dynamic loads of 150 and 700 psi are applied to the right-left and middle pads of the digital sansak. The results indicate that the stress values on each frame do not exceed their yield strength. Specifically, the lowest stress (0.002 to 0.0641 MPa) was observed on the right-left pad with a 150 psi impact, while the highest stress (0.01 to 0.308 MPa) was found on the middle pad with a 700 psi power punch. Deformation values also varied, with the maximum recorded deformation being 0.00067 mm for the center pad at 700 psi. These findings suggest that the digital sansak is a robust tool for measuring and analyzing the dynamic strength of punches and kicks, offering valuable data for improving athlete training programs. Further research is recommended to enhance the design and application of digital sansak in various sports disciplines. © 2025 Author(s).
