From airplane, jump out,
sky dive and open parachute,
glide down to water,
freedive into the hole. Wow!

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).
