120m PB Dynamic Questions

[OceanMan]

Wes,

I don't think your warm up is so good.
You were probably very hyperventilated and you would probably have done a bad BO at 125-130m.

My 2 cents...

My breathe up is total 12 minutes sitting on edge of pool with 4 min slow relaxing breaths, 4 min of 4 count in breath, 8 count packing, and 4 count exhale, then 4 min of quick very deep breaths followed by last breath with full pack, maybe 15 gulps. Is this a reasonable breatheup? Also at the end I stopped because I "got scared" and "felt funny, like being all of a sudden paranoid", I didn't feel like I had to stop to breathe like I do when I do the static dryland apneas. I also didn't have any low Oxygen symptoms like stars in eyes or leg tingles or anything like that (and I have experienced these before in different open water deep feedives) and had very clean and easy exits.

The 4 min of quick very deep breaths is a lot. I hadn't noticed that when I first read your post. If you felt fine afterwards, then it might be ok. It would be worth trying a much shorter warm up to see what happens. I have done better with shorter warm ups than with longer ones.

Naiad and Ocean Man,

Thanks for your views. I will try some different breatheups as I have now read about more in these forums.

Cheers Wes

Probably, you did your attempt without weights? If it was so, you had to overcome buoyancy in the shallow pool by high speed. I think you have potential to increase distance simply by using weights to lower speed and oxygen consumption.

Victor,

Thanks, this is excellent tip and I think you are correct. If I pack then I am positively bouyant down to about 7 meters (21 feet) so I would be "fighting" the bouyancy with some of my energy while swimming in a very shallow pool without weights.
Cheers Wes

You not only fight bouyancy without a neck weight, you also swim in a diagonal attitude. This would add around 3 metres extra distance during a 100m swim. In a shallow pool your fin will hit the surface while your hands scrape the bottom. You follow the pool along the floor to the deep end, rather than staying horizontal to the surface.

Hook Breath: Used at the end of a long dive, inhale, hold it and bear down with your chest and diaphram. The idea is to force 02 into the blood stream as fast as possible.
