We now have several reports of increased strength manifested in more reps with greater weight, occuring very shortly after beginning C60 supplementation.
A putative mechanism of C60 action is improving mitochondrial function by limiting ROS damage by virtue of its anti-oxidant effect when it takes up residence in the mitochondrial membrane. This may happen, but I do not believe it would account for the gain in strength being reported: first, lifting is not an aerobic activity. It can be accomplished with fast-twitch muscles that have few if any mitochondria, and it occurs rapidly enough that (aerobic) mitochondrial function shouldn't be involved. Second, strength depends on size and number of muscle fibers. I do not think these could increase significantly in the short time in which gains were reported.
This could be a placebo effect, but the degree of improvement reported casts doubt on that to my mind.
There is a training effect seen in cycling, where greater strength is achieved through training, enabling muscle fibers to fire together, so it is possible to deliver more power by recruiting the muscle fibers more efficiently. I suppose it is possible C60 is improving the coordination between fibers without increasing their number or individual strength, though I do not know of a mechanism to explain such an effect.
Any other insights into what may be going on here?
