Simplifying the motion capture–to–simulation workflow: analysis of the resemblance between estimated and measured Fluid force

This study aimed to simplify swimming simulation workflow using motion capture data and evaluate the resemblance of fluid force estimated from simulation and pressure distribution. Marker coordinate was collected during swimming using a motion capture system, while small pressure sensors attached to the hand and foot measured pressure distribution. The simulation used the coordinate data to reproduce relative swimming motions, with absolute angles of body segments input to calculate fluid force. The simplified workflow reduced the number of required inputs and demonstrated close resemblance in the temporal changes of hand and foot fluid force between actual swimming and the simulation.
