More anecdotal evidence. Regardless, if resveratrol does in fact improve some sorts of sport performance that does not mean that it is good for health or longevity, compare anabolic steroids. It should also be noted that both carnitine and CoQ10 has peer-reviewed human studies suggesting enhanced sports performance, every one of them worth more than the anecodatal claims from a coach on a web forum. Sure, regarding sports performance there are other studies suggesting no effects, so the effect may not exist or be related to a particular sport and its requirements. But this just shows the importance of large, multiple, carefully controlled, double-blind, placebo-controlled, human studies and that very little weight should be given to the anecdotal claims on a web forum.Except that we have some careful measurements that have been made supporting Kenj's observations. Cyclist in need of Mitochondrial Biogenesis; the numbers that I observed using a cylcing ergonometer (one with with lab accuracy) support this; I never was able to get similar results with ALA and ALCAR.
That is simply outright false. What are the "mostly in virto" studies in this link for example:The references you gave are secondary, the studies mostly in vitro, and sometimes contradicted by other studies, and on the whole not more convincing than those studies we have for resveratrol.
https://healthlibrar...kiid=21450#ref1So you consider the ancedotal reports regarding the homeopathic supplements valid? Regarding the cyclists, see first response.Observational studies -- and many of the reports we have here amount to that -- are valid, though dirtier than controlled double blind testing. Here resveratrol's effects are noted by a coach realizing something unusual is going on in his athletes, he grills them, and finds they have been taking resveratrol supplements. After asking for information in this forum, he then tries to measure the effect in his own regimen. To his surprise, he notes nothing until the third periodization training cycle, where despite continued increase in training intensity he notes performance improvement that would be obtained with a slow taper. Not something one would expect. Placebo effects are generally noted at the onset of a study, and tend to disappear with time.
This is somewhat more than anecdotal, where actual measurements are involved. The coach's report is not anecdotal, in that he was measuring hiis athletes, and found performance variations inconsistent with their past performance, and was able to replicate the results in his own training, and elucidated an unexpected characteristic of the effect. While not a double blind study, the gol standard, this qualifies as an observational sudy, and his measurements are careful enough it could be written up as such in a journal. It is quite different from the homeopathic stories, far beyond I"I took a pill and I fee the energy".
You link is still secondary. And just because the references it points to are published, this still means little; even hmeopathic studies get published. You have to look at multiple studies, and nt cherr-pick the favorable ones.
As far as your preferred supplements go, while I they are on my short list of possibly beneficial substances, I do not find the published evidenceas referenced in pub med to be any more convincing than the evidence for resveratrol. The evidence that resveratrol induces mitochondrial biogenesis is extremely strong. The decline of mitochondria is a critical defect that comes with aging. Anything that improves mitochondrial health is likely to be anti-aging. Sports improvement is a side effect, but one we can measure that provides favorable evidence.
