All those words- what do they mean?
| Constant weight - CWT | The king discipline - as deep as you can with the fin of your choice. |
| Static - STA | Breatholding without moving |
| Dynamic - DYF | As far as you can with fins in a pool. |
| Dynamic no fins - DNF | as above but no fins. |
| Constant no fins - CNF | Breaststrokes as deep as you can. |
| Free immersion - FIM | Pull yourself down and up without fins. |
| No limit - NLT | Whatevere means as deep as possible. Weighted sled down - airsack up. |
| Variable weight - VWT | Weighted sled down - pull yourself up (with fins) |
| LMC | Loss of motor control (also called samba) happens at low oxygen levels. Gives DQ |
| BO | Unconciousness due to low oxygen in blood and/or brain. Gives DQ |
| Rope violation | penalty points for touching the rope more than once or at the wrong point. |
| DQ | Disqualification |
| Diving response | See *below |
| *Bradycardia | Drop in pulse |
| *Anaerobic metabolism | Cells ability to function without oxygen |
| *Vasoconstriction | Bloodvessels shrink. Bloodstream directed away from limbs for the benefit of heart, lungs and brain. |
| *Splenic contraction | Releasing red blood cells carrying oxygen |
| *CO2 tolerance | After repeated breatholds |
| *Higher blood pressure | To "compensate" lower heart rate and less stroke volume. |
| *Less stroke volume in heart | To "compensate" vasoconstriction. |
| Blood shift | Blood fills up bloodvessels in the lung and reduces residual volume. |
| Blood shunt | Term wrongfully used for vasoconstriction |
| Residual volume RV | Whats left in the lungs after FULLY breathing out |
| Vital capacity VC | the maximal amount of air you can exhale in one breath |
| Functional residual capacity FRC | What´s in your lungs when relaxing diapragma/stomachmuscles. Just let out your breath without any force. |
| Total lung capacity TLC | What your lungs contain when taking a full breath |
| Lungpacking/ carp breathing | Swollowing air into the lungs |
| Hypoxia | Lack of oxygen |
| Hypoxemia |
Lack of oxygen in the blood. |
| hypercapnia | The presence in the blood of an abnormally high concentration of carbon dioxide. |
| Hypocapnia |
A condition in which there is an abnormally low concentration of carbon dioxide in the blood. This may be caused by hyperventilation |
| Hyperventilation | Higher then normal intervals of breathing (cycle) – lowers carbon dioxide (below usuall 4.5%) |
| Stroke volume | Amount of blood in each heart stroke |
| MAP | Mean arterial pressure |
| ECG | Measures the heart rate and its function. |
| 02 narcossis | Oxygen narcossis due to pressure at depth. |
| N2 narcossis | Nitrogen narcossis due to pressure at depth. |
| CO2 narcossis | Carbon dioxide narcossis due to pressure at depth. |
