You don't need a force sensor to map the force-velocity curve in swim training — gear already does it. Paddles, parachute, pull buoy, fins, and bare hands each shift a swimmer's F-v operating point by changing the resistance they face. Capturing which gear a swimmer used during a timed set turns the stopwatch from a time recorder into a force-velocity measurement instrument. No new hardware, no lab protocol — just one variable captured at the right moment.
