Swimming stroke efficiency

Much more needs to be done to determine the best combination of stroke form, breath management, hydrodynamic vortices control, etc. By using real-time software (coarse-grained) and 3D triangulation to measure flow rates, sensors help to get a better view of all-around max aerobic efficiency and performance per O2 and per nutritive requirements (amount of food consumed per dive series).
