Like skateboarding acceleration in surfing on a hydrofoil with muscle power is achieved by a constant sinusoidal motion. Both are challenging sports to begin with because learning the complex up and down movements takes time, skill and reflexion. The interplay of rotating joints and applying forces at the right time is hard to perceive, understand and to transfer into muscle memory. Since the motions in skateboarding on pump tracks and hydrofoil pumping are similar, we are comparing both motion sequences with inertial measurement units and 3D pose estimation. We postulate that learning the physically challenging and expensive hydrofoil pumping can be improved and accelerated by training with skateboards. Therefore, we are capturing forces with inertial measurement units and validate them with 3D pose estimation. Finally, we are comparing and visualizing the motions and forces of the boards and the skeleton to show the similarities within the y- and z-momentum.
