Advanced Swimming Kinematics
Calculate stroke rates (SPM), model distance per stroke (DPS), evaluate SWOLF efficiency scores, breakout speeds, and hydro-dynamic drag suit resistances.
Configure Parameters
Classification calibrated specifically for a 25m pool profile. A lower SWOLF indicates highly streamlined mechanics and optimal hydrodynamic positioning.
