$75 per article, suggest your own reviewers, which may not be evidence of dubious review, but is certainly not as independent as the gold standard (I have never suggested reviewers for my publications, though I have often been able to work out who they are.) Whether those reviewers are used is another matter. I just feel it should be taken with a pinch of salt. After nine years nobody has repeated what sounds like an interesting finding. If there was a plausible mechanism whereby iron loading without a concomitant haemoglobin increase could have an effect on VO2 or DO2 then I would be more inclined to believe. Unfortunately these papers are often quoted as proof positive and go uncriticised, particularly on websites. |

I didn't find any, though I only spent half an hour. It's also worth noting that the paper hasn't been cited much. Any subsequent larger study should have referenced it. |

I wonder if the new ovid clinical tools searchie thing might be useful in this sort of case... (i dont work for them by the way nor have any interest in the sucess of said product) |

I think Johnny is right to urge caution about the article. However, I only read it yesterday, and the conclusions for my own case came from my own research plus talking to both running coaches and colleagues (I have a research background and now happen to work in a Nutritional Sciences Research Division at a top UK University). After further discussion, my doctor supports my decision to take iron supplements. Just a note on the journal and on publishing scientific research. My Nutritional Scientist colleagues strive to publish in Am J Clin Nutr - it is the gold standard journal for Nutritional Science. I strongly disagree with journals making authors pay to publish their work, but unfortunately it is extremely common that the best scientitific journals (particularly American ones) charge to publish. In many cases scientists have no option but to pay the extortionate page charges demanded from journals (which can be over £1000). Suggesting reviewers is also common in scientific publishing. However journal editors send manuscripts to more than one reviewer and will always also send it to somebody who hasn't been suggested by the authors. The suggestion of reviewers helps the journal editorial team target the most appropriate experts for the field. I have been on both sides of the fence. Peer review is rigorous. |

£2000 is the article processing charge maximum at which it is no longer an overall beneficial model for widening access to the research btw. Usually, for the pricey ones it is expected that the research funding body or institution pays rather than the author directly. For journals where you dont pay upfront, someone else (i.e. UK HE and therefore mostly the tax payer) is paying to read that article later down the line...I am neutral about OA on the whole, but I do think its good for the scholarly publishing industry to explore lots of models or it does risk going the same way as newspapers are (which is also causing a decline in journalist standards and editorial standards). Hipps - I am not medically trained - whats TSAT? |

I went to Holland and Barratt yesterday and bought Spatone, an iron rich liquid, so hopefully no stomach repercussions. Took a dose at lunchtime, ran at night, 6 miles the day after a 10km race. Felt fine, although did run quite slowly. Woke up at 4.00am wide awake - this never happens to me!. Took me ages to get back to sleep. Hope this is not a side effect!! Rest day today but a very hilly 12 miles tomorrow. It could be quite difficult to measure the 'effects' as I've also just given up quite a stressful job, so increased energy levels may also be due to that.

More non peer reviewed stuff, but an experienced coach's observations on SF levels. There do appear to be potential side effects to taking iron when not necessary so it's not a case of just chewing on an anvil in your spare time. runningtimes.com The usual rules apply when trying to persuade a GP to do an iron test. Pretend you have all the symptoms and let the GP suggest it. |

there are very serious effects from taking iron if you're not deficient and it can be fatal It is extremely dangerous to just take iron supplements blindly - do not take them unless you have a proven deficiency |
