A year or so ago, their sports scientists were calling for volunteers amongst competitive cyclists to participate in the testing of sodium phosphate.

I wasn't able to find a link to the study results, do you know if its even published on the website or not?
cheers
duro said:Hi all.
having loaded with SP how long do the improved performance effects last?
is it a case of load for the 4 days up to race day and when the 'effort' is over then youre back to scratch or is there a carry over period?

Roadie_scum said:Ric, is acute hypocalciaemia a concern with Phosphate use?
ric_stern/RST said:Possibly. No one has tested that per se, and the actual data available on phosphate loading in general is limited. Current recommendations are that phosphate loading should be limited to four times per year spread out evenly. When i was doing my thesis on phosphate loading, the thoughts were to either load maximally four times per year, or that continual use of phosphate would just cause it to be excreted.
i'd certainly err on the side of caution and limit it to four times per year, and not use it, if for e.g., you're osteoporotic.
additionally, it's worth noting that if you consume large amounts of (e.g.) cola you may be subjecting yourself to leaching from the bones in a similar manner.
i can't currently think of any [legal] supplements that don't have _some_ health risks associated with them.

Roadie_scum said:Cheers, that's about what I thought the situation would be. I take it none of the participants in your study exhibited the classic twitchiness associated with acute calcium deficit or other noticeable signs, and you don't know of this being reported with acute phosphate loading for ergogenic effect? I couldn't find any suggestion that this had occured in other trials.

Thanks you for explaining. Must admit I had a laugh from your last phrase...ric_stern/RST said:for the purpose of clarification, bicarbonate loading and sodium phosphate loading work by completely different mechanisms (although the mechanisms behind phosphate loading have yet to be fully elucidated).
bicarbonate loading tends to work for only very short events (say up to 10-mins). you need a very large dose of bicarbonate (0.3 g/kg body mass, e.g., a 70 kg person would require 21 g). as i understand it, about 50% of subjects in studies looking at bicarb loading suffer *severe* GI distress. To put it gently, if you decide on trying bicarb loading make sure you stay close to a toilet in case you're one of the 50% who suffers from "distress".

Huuuuuuampppahammmmmmmric_stern/RST said:you may not be laughing if you try it!
i strongly encourage you to listen to ric, makes for easier competition.ric_stern/RST said:leaving aside any discussion on moral/ethical grounds, it's hardly a "marginally better performance". We found an increase of ~ 8%, which represents a highly significant increase, and by way of a comparison (not a suggestion!) is only slightly below the increase from Epo supplementation (~ 10%).

I tried it last year in for a TT as the first stage of a stage race. I did do about 4% better power in the TT than I did in training leading up to the event but I have no way of telling if that was because of:Bailsibub said:I used to use So Phos when I was racing semi-pro. The stuff is the BOMB (no other way to put it).
