So actually all these WADA doping controls (in its current form) are pretty useless for freediving and are just good for filling pockets of laboratories owners (and emptying those of freedivers). I bet that 90% of the expensive laboratory tests are made for substances that would help no freediver, and oppositely substances that should be banned are not being tested at all. As for using garlic and other "natural" substances - that is is quite a controversary topic. Personally I think that even using such natural substances should not be allowed without any control or limits. And I also do not quite agree that using natural nutrition, herbs, or drugs is always beneficial for the health. Everything has its limits, so once you start abusing it, it will flip the natural balance in your body and start damaging it. Imagine: if a freediver gets better results after consuming 100g of garlic extract, the next one will try it with a pound. Not only gas masks for the audience, organizers, safety divers, and judges would have to be mandatory, but the effect may indeed at some point start damaging the health of the freediver. And the next freediver will get super concentrated extract from one ton of garlic. In the next stage scientist will genetically manipulate garlic to have 100 times stronger effect. Etc, etc. So now, where exactly is the limit of natural nutrition and doping? I am afraid we cannot tell it without making serious scientific research seeing how the effects and the risks are related to concentrations of those substances and start setting allowed limits (better lower than higher).

Eric exactly how sick were you after consuming 100gm's of garlic extract?

How did you learn about the affects of using garlic for freediving? Do you have any references on it? It would be interesting to understand why it causes the benefits it does for freedivers.

Garlic was used by polynesian freedivers as well as Jacques Mayol, as described in Homo Delphinus. My serious experiment in garlic was based on the following study which I purchased online. Here is just the abstract:
The Protective Effect of Allium sativum L. Clove Aqueous and Methanolic Extracts Against Hypoxia-induced Lethality in Mice Hossein Hosseinzadeh* and Nargess Sadati Pharmaceutical Research Center, Pharmacodynamy and Toxicology Department, School of Pharmacy, Mashhad University of Medical Sciences, PO Box 91775-1365, Mashhad, I.R. Iran. The antihypoxic activity of Allium sativum clove (garlic) aqueous and methanolic extracts was studied in mice. The extracts of garlic showed that the antihypoxic effect was dose-dependent. The minimum effective doses of aqueous and methanolic extracts were 0.2 g/kg and 5.12 g/kg, respectively. Phenytoin, 50 mg/kg, and Rphenylisopropyladenosine (R-PIA), 1.6 mg/kg (R-PIA) as positive controls increased survival time up to 52.5 ±2.9 min and 120.5 ± 6 min, respectively, compared to normal saline (34.73 ±0.71 min). The high doses of aqueous (16.9 g/kg) and methanolic (12.8 g/kg) extracts increased survival time up to 73.17 ± 4.9 and 68.41 ± 3.7, respectively. These results indicated that the extracts of A. sativum cloves have a protective effect against hypoxiainduced lethality in mice. Copyright © 2003 John Wiley & Sons, Ltd.

Seizures Accelerate Anoxia-Induced Neuronal
Death in the Neonatal Rat Hippocampus Volodymyr Dzhala, PhD, Yehezkiel Ben-Ari, PhD, and Roustem Khazipov, MD, PhD Seizures occurring in infants with hypoxia are frequently associated with an ominous prognosis. There is, however, no direct evidence that seizures are involved in the pathogenesis of hypoxia-induced neuronal damage. Here, we report that seizures significantly aggravate the hypoxic state by accelerating rapid anoxic depolarization (AD) and associated neuronal death in preparations of the intact hippocampus of neonatal rats in vitro. Under control conditions, prolonged episodes of anoxia/aglycemia induced rapid suppression of synaptic activity followed sequentially by brief bursts of epileptiform activity and then by rapid AD. AD was associated with irreversible neuronal damage manifested by irreversible loss of the membrane potential, synaptic responses, and neuronal degeneration. Aggravation of electrographic seizure activity during anoxic episodes by the adenosine A1 receptor antagonists DPCPX and caffeine or the g-aminobutyric acid-A receptor antagonist bicuculline or pretreatment with 4-aminopyridine accelerated AD and associated neuronal death by up to twofold, whereas blockade of seizure activity by the glutamate receptor antagonists or tetrodotoxin significantly delayed the onset of AD. This report provides direct evidence for the need to prevent seizures during neonatal brain hypoxia. Dzhala V, Ben-Ari Y, Khazipov R. Seizures accelerate anoxia-induced neuronal death in the neonatal rat hippocampus. Ann Neurol 2000;48:632–640 -------------- Influence of combined treatment with NMDA and non-NMDA receptor antagonists on electroconvulsions in mice Stanistaw J. Czuczwar *, Kinga K. Borowicz, Zdzistaw Kleinrok, Piotr Tutka, Tomasz Zarnowski, Waldemar A. Turski Department of Pharmacology and Toxicology, Medical University School, Jaczewskiego 8, 20-090 Lublin, Poland Received 28 December 1994; revised 25 April 1995; accepted 28 April 1995 Abstract a-Amino-3-hydroxy-5-methyl-isoxazole-4-propionate/kainate (AMPA/kainate) receptor antagonists (at subthreshold doses against electroconvulsions), 1-(4-aminophenyl)-4-methyl-7,8-methylenedioxy-5H-2,3-benzodiazepine (GYKI 52466 at maximally 5 mg/kg) and 2,3-dihydroxy-6-nitro-7-sulfamoylbenzo(F)quinoxaline (NBQX at maximally 20 mg/kg) enhanced the protective effects of NMDA receptor antagonists, MK-801 (dizocilpine) or 2-(2-carboxypiperazine-4-yl)-l-propenyl-l-phosphonic acid (o-CPP-ene), against electroconvulsions. Similarly, MK-801 or D-CPP-ene reduced the EDs0 values of both NBQX and GYKI 52466 against maximal electroshock. The adverse effects of D-CPP-ene, evaluated in the chimney and rotorod tests, were potentiated by both GYKI 52466 (2.5 mg/kg) and NBQX (10 mg/kg). Also, n-CPP-ene (0.1 mg/kg) worsened the motor performance of mice pretreated with GYKI 52466 in the rotorod test. Neither MK-801 (0.025 mg/kg) nor D-CPP-ene (0.1 mg/kg) affected the NBQX-induced impairment of motor coordination. Similarly, GYKI 52466 (2.5 mg/kg) or NBQX (10 mg/kg) did not influence the performance of mice treated with MK-801 (0.2 mg/kg). It may be concluded that the blockade of more than one subtype of glutamate receptors leads to a more pronounced anticonvulsive effect when compared with the effect of blockade of an individual receptor subtype. In some cases more efficient seizure protection was not associated with increased adverse effects. Keywords: AMPA receptor antagonist; NMDA receptor

If you read the two above studies (in full), you will find that they show that:
- Hypoxic seizures cause some brain damage, and the damage is caused by the seizure, not the early blackout - Some drugs can prevent the seizure part of the blackout, and also delay the blackout and protect the brain dramatically - and there are also easy to obtain herbs which operate in the same mechanisms If such a herb were administered during a competition, there would be no sambas, only blackouts. Therefore, disqualification would be extremely obvious.

One could start with actually excluding anything that is NOT beneficial for freediving. We would come down to some 10-20-30 (?) substances on the IOC/WADA list that would be forbidden for freedivers. I imagine this work would be pretty easy and there are lots of medics/scientist out there who no doubt could do this for free for us. Its just a question of asking (the right way:-). Problem is - the tests will probably cost the same. Wada has its routines and they check for everything on their lists. Sebastian apnea and doping

this is sort of my oversimplified interpretation of what we should consider natural, but it also still begs the question "how do you enforce it?". Looking at the underlying philosophy of freediving, it seems that the goal is to get back to our primal dive capacity. The capacity we are born with, and capable of attaining on our own, as if we lived without any form of technology to develop pills or supplements. Anything we cant produce from scratch, or pick out of the ground could be considered unnatural, right? i suppose this is a bit of clouded issue anyway, because we use fins, wetsuits, masks and the like. just my $.02.

Thanks for the thread Sebastian. As soon as I can add something, I will. Every time I think I understand drugs and doping I get another surprise. Who'd have believed that Vinokourov would pull a stunt like that? For what?

Very interesting thread and lots of good points raised.
I think that we only have to look as far as professional bodybuilding to see where a free-and-easy approach to performance enhancing drugs can take any sport. None of those guys seriously deny taking steroids, and as a result there are basically two sports - one with 'natural' body builders, and one with the guys who do as they please. But as pointed out many times, it can be hard to know where to draw the line.

I've been following the coverage of the controversial withdrawal of Rasmussen, the current Tour leader, by his own team.
Here is an excerpt from the Bicycling.com blog from today's stage (17), which I think is pretty interesting and relevant to this discussion: Quote:
Does AIDA perform a hemotocrit test? (I have never heard of it). While this is controversial because of assumptions about the effects of freediving on blood volume immediately following a dive and in the long term, I would imagine that diving doctors could develop a protocol. It would be interesting to know the hemotocrits of competitive divers.

Maybe there may have been some discussion inside Aida to check blood haemoglobin values in the future, I guess.
We tried a little blood control/study here in Finnish nationals last year with cheap equipments just to see how these systems and our blood values may work (we lended our equips and a nice doctor - kimmo |

Very interesting thread, science and competition ethics-wise.
So basically, whoever wants to protect himself easily from anoxic depolarization damage without becoming a herbalist could just get this? Bulk Nutrition - Retail Nutritional Supplements, Bodybuilding and Fitness Articles, and Bulk Specialty Powders! How is it different ethically (and medically) than consuming a herb that raises your GABA levels? Is anything beyond adaptation that results from training is un-natural now? I don't recall hyperbaric tents being looked at as cheating, and it's an adaptation that doesn't result from training. Is banning a protective substance ethical only because it might hurt competitiveness? On the other hand, raising the bar in a way that excludes people that aren't "as dedicated" ethical? What is more important? I don't think we're supposed to model ourselves by our aquatic predecessors if they ever existed. I doubt any of them reached the age of 70 years or 70 meters depth.... |
