Dynamic Apnea Safety Rules
Posted By Aharon & MT Solomons on 1 December 2003
Safety is vital in Dynamic Apnea. People tend to stretch their limits, as there is no depth involved.
Apart from being a competitive event in itself, dynamic apnea is probably the single most important training for Fixed Weight, other than doing Fixed Weights (FW)training itself. Dynamic is breath-hold with stress as you would have in FW and here you have the opportunity to do hypoxic training, i.e. lactic acid training, to train the specific muscles you would use in FW and to train style and rhythm. Monofinners should be covering 50m (in a 50m pool), in about 25 undulations.
We FREEDIVERS instruct with the maxim 'A 10% improvement in style equals a 10% improvement in results whereas a 10% improvement in fitness IF it is invested in poor style may not even produce a 1% improvement in results.'
This is particularly true of dynamic, but if we remove equalisation problems from the equasion it also applies to FW and Free Immersion. The recording of dynamic is important and can produce a wealth of information, (i.e. distance, time, number of kick cycles or undulations, recovery time etc.). This is particularly interesting when a heart monitor is employed.
Using the Tables
As the length of pools varies it may be difficult to find an exact number of whole pool lengths to express an ideal 75% of your maximum apnea distance, i.e. if your maximum is 85m and you had at your disposal a 33m pool, you would set Table A with a dive distance of 2 lengths. If you had a 50m pool at your disposal you would set it for 1 length. With a 25m pool, you would probably set it at 2 lengths. Thus your setting could be anywhere from 60-80% of your maximum. If your setting is closer to the bottom range of distance in order to make the exercise more challenging you would immediately reduce the 'rest times'.
Your safety diver (partner) should be ready to meet you during the last stressed 25% of the exercise. Here we are basically talking about a 50m pool scenario. In Table A, he should be recording not only the length of time it would take to do each length but also the number of kick cycles as well as being ready to intervene in the case of Shallow Water Blackout (SWB).
The objectives of dynamic apnea are to increase apnea times in movement and to improve style and hydro-dynamicism.
