Comparison of Water Exercise Equipment  

The resistance surface is measured facing the direction of  movement, perpendicular to the line of momentum. All equipment is used isokinetically in a three dimensional, viscous environment. Measurable resistance is the combination of variable gradients on the equipment with the Navier-Stokes equation of fluid motion to produce pounds of force. Streamline ability is a laminar flow isolation technique of returning the equipment to the starting position of a movement with no resistance, no turbulence, zero vorticity and minimal drag.
