Freediving Lingo¬†are the terms and phrases commonly used by freedivers, which can seem confusing to those that are not familiar. This program focuses on freediving lingo and Erin explains those terms and phrases so you can understand.
Blackouts can be caused by many different factors in freediving, whether you ran out of oxygen or if you breathed the wrong way and it decreased blood flow to your brain. There are numerous different reasons one may have experienced a blackout, but regardless the outcome is the same. And simply a blackout means there is a cessation of breathing.
If you are holding your breath during freediving, you are undergoing apnea, temporary cessation of breathing.
Pool disciplines include static apnea, holding your breath for time, dynamic apnea with fins, which means swimming in the pool on one breath for distance with fins and dynamic apnea without fins, which is swimming in the pool on one breath for distance without the assistance of fins.
There are also the self-powered disciplines. Constant Ballast or Weight with fins, which is when the diver goes for a depth with a constant weight with the use of fins. There is Constant Ballast or Weight with no fins, when you are going for depth with constant weight and no fin assistance. Free Immersion is when you are using a line to pull yourself down to depth.
No Limits is a discipline when one uses a weighted sled to take them down to depth and a lift bag to get back up to the surface or Variable Ballast, when you use a weight to get down and you make a buoyant descent with either kicking or pulling yourself up with a line.
A barotrauma is a pressure-related trauma or injury. You can damage your ears during a dive, which is one form of barotrauma or you can have a sinus squeeze or blockage, which is also considered a barotauma. Others included are a chest squeeze, trachea squeeze, and intestinal squeezes.
A sled is just a device that divers use for No Limits or during Variable Ballast to get down to depth. It is merely a platform for the diver to hold on to that control their position in the water. They add weight to the sled in order to get them down to depth.
