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.
