Hello all,

What a wonderful forum I discovered here! So I thought about introducing myself:

I have always been a water enthousiast. I live at the northsea in belgium, I used to be at the beach every day in summer. I loved to swim, snorkel, fool around in the water.

I am in a wheelchair because of a muscular dystrophy. This means my muscle strength deteriorates over time, I am now 24 years old and can't really swim a lot of distance anymore (let's say max 50m horizontally in one go). So I am always trying to find new stuff that is possible for me.

Since a couple of years, I have developed an intrest in static apnea, every summer on holidays I practice my apnea's in the swimming pool. Not really serious, just little friendly competitions against my dad (who is an experienced north sea wreck diver (not freediver)). I always thought I was quite good at this because I could win most of the time :)
2 years ago I started doing this every week in our local swimming pool, and my record then was 3:00min.
Partly because of my condition, I have a lot of problems swimming in cold water, the little strength I have is affected a lot by cold, so I did these apnea's in the jacuzzi bath which is nice and warm.

The last year I have not done much excercise anymore, because going to the swimming pool is quite hard for me, changing clothes and having cold afterwards etc...

This week I have seen a youtube video ([ame=http://www.youtube.com/watch?v=uQITWbAaDx0]YouTube - Guillaume Nery base jumping at Dean's Blue Hole, filmed on breath hold by Julie Gautier[/ame]) which has really got me interested again in apnea/freediving. I then remembered I could go to the nemo33 swimming pool (which is also nice and warm) in brussels and try and reach the bottom. I soon realized this is not really realistic after reading some posts on this forum and watching some youtube videos about those depths.
But I do want to train more, who knows, maybe I can reach 10m or even 15m? The deepest I have gone was only 5m, which was obviously no problem, but it was the max depth of the pool.
This seems a really good excercise for me, physically it's not that challenging for my muscles, but I do train my lungs and my heart, which is important for me.
My record was 3:00min, but I think I can do much more. I read about the CO2 and O2 tables in the beginners guide in this forum, and had no problems in completing them.

I saw most freedivers want to be buoyant on -10m, so they can easily swim up and down. I can't really do that, I normally use a heavy lead-belt (does this has a particular name in english?) which takes me to the bottom, there I let go of the belt and go back up. I am very buoyant, it is almost impossible for me to go under without lead, so I go up very easily (and fast) when I let go of the belt. Could this be a good way to dive to 10-15m?
Does someone has experience with freediving, while not being able to swim independently down and up?

Greetings,
Jen
 
Hi Jen and welcome to DB. I don't know much about muscular dystrophy so I would start by saying that it's probably a good idea to consult a knowledgable doctor on what they implications of Freediving and breathholding are. There are lots of ways the body is affected both by breathholding and also with pressure. Better to be cautious and safe :)

Just a few things thoughts on what you have written above - these are just my thoughts and I have no specific experience whatsoever:
1. Firstly and most importantly make sure you don't do ANY freediving without having a competent buddy. This goes for anyone but even more important in your case. Should you get in any trouble, your buddy should be able to bring you to the surface from at least 10-15m and know what to do next..

2. It obviously takes very little effort to go down to 10-15m if you are holding a heavy weight belt so getting down shouldn't be a problem in that respect. However you do need to be aware that the air in your lungs compresses as you go deeper and you do become less boyant which means that there will bea depth that you will continue sinking even if you let go of the belt. The depth varies from person to person but we're not talking great depths here, probably somewhere around 10m or so. The closer to neutral boyancy you get the slower you will obvious float up... Maybe it would be easier to pull yourself up a rope? (I guess it depends which muscles are stronger)

All the best - I am sure you can do it. Just need to take it slowly and be careful. Dive safely ;-)

Hello Simos, thank you for your answer!
I will ask my pneumologist and cardiologist next time I go and see them (in 3 months), I won't do any significant depths till then, I have to train first :)

I know I always need a capable buddy, my dad will be there if I dive deep, and he is a very capable experienced diver who knows the dangers of freediving. When I just do static apnea's in the pool, my girlfriend is there to check me every few seconds. She also knows what to do if I don't respond.

Regarding your second point, I don't think it is that hard to go 10m either, except for equalisation maybe, but never had problems with this when going 3-5m deep, so I hope this will be the same for greater depths. I do fear the point of becoming less boyant. I want to be able to get up independently, and pulling myself up a rope is not really possible for me I think. My dad could always pull me back up if I don't go up by myself. If I am in sweet water, without a wetsuit or anything, and stay upright, my shoulders are out of the water, so I have a really high boyancy!
I will have to experience this by going deeper everytime, not going straight to 15m :)
 
You could use a climbers harness-rope-buoy as an extra security. Maybe also a trimvest aka 'slabbertje' with a small air bottle you can operate. With practice your dad should be able to make repetitive dives of 1 minute to 10m, enough to dive along and provide security.

Enjoy your dives, create some good memories!
 
Hi Kars,
I am intrested in the 'slabbertje', as I am also dutch, I kinda get a picture of what it would be. Could you give me a picture of such a slabbertje, or the correct word?
 
The "slabbertje" is one of the first, if not the first model dive buoyancy device made:

Hello Jen! I know that swimming is excellent exercise for all of us. My husband uses a wheelchair and he swims and dives a lot. He credits it with keeping fit and sane. He scuba dives and has taught a number of people with disabilities to dive. It seems you are very good at free diving. I would like to become a better free diver. Oh, in English we call the lead belt the weight belt or just say, we need some lead. I just joined DeeperBlue today and am happy to have found your interesting post right away. Stay warm and keep diving.
