Hi All,
As people were doing so well with static training last Monday I have created some low O2 and low CO2 tables for the October session.
There are 10 separate tables, getting harder and harder, so you can try out a table you think you can do and drop down or step up if required.
They have been laminated for pool use and will really improve your tolerances to low O2 and high CO2.
James and Katie discovered the benefits of neck weights last session.
These are made from a bicycle inner tube filled with leadshot and a plastic buckle fitted to each end.
The advantage of this kind of weight over a more normal weight belt is this:
Legs are generally heavy and the chest when full of air is very buoyant. To be able to swim in the most aqua-dynamic way, the body has to be very horizontal with the direction of travel.
Swimming up or down the water column this is not usually a problem but when practicing dynamic apnea, the chest, being floaty, wants to rise.
To counter this we have to angle ourselves in a legs up attitude, destroying our ability to slip through the water easily.
The answer to this is the neck weight. So, paradoxically if we are swimming legs up, we need to weight ourselves above our lungs to bring ourselves horizontal. I had a hard time trying to explain this to a local guy in Kalymnos during the summer camp and I’m sure he was still not convinced at the end since he refused outright to try it out. He wanted more and more weight on his belt instead!
My neck weight is 2Kg. Katie needed only the 1Kg weight; whereas James needed both to keep him level, though I think 2.5Kg would be his optimum. So everyone is different obviously and needs their own custom weight, just as we have to adjust our weight belts to suit the individual.
I shall be holding a masterclass on how to make these (I think commercially unobtainable) items in the October session. They are very easy and quite cheap to fabricate. Now here’s one I made earlier………..
