Any physical activity is not without some level of risk, so it's not surprising that a few case reports have come up, which are what most of the publications that mingshi mentioned. I would recommend, mingshi, that you might want to consult someone with a scientific/medical background (i.e. someone with at least a science/medical degree) before you cut and paste a PubMed search result on a big global forum where not everyone has a scientific/medical background. Some of the abstracts shown are easy to follow, while others would make one's head spin! I think the best approach for someone citing a PubMed result or any other scientific article is that they be able to translate it into everyday language, as best they can, or ask someone who can. My feeble attempt at this is outlined on the second page of the "women and do" thread. One day I will figure out how to put a link to that...

The article by Lee doesn't address an injury or ill-effect at all but an increased speed in muscle responses of kendoka and karateka! My muscles will work faster over time, whee!

Regarding march hemaglobinuria (hemaglobin in the urine)...
March hemaglobinuria is when the inner contents of crushed red blood cells (i.e. for kendo: frequent bruising, high-impact footwork) are excreted by the kidneys into the urine. Hemaglobin, the protein responsible for binding oxygen for delivery throughout the body and also responsible for red blood cells being red (hemaglobin has iron attached to it too), winds up in the urine along with all the other stuff that was inside the squashed red blood cells. Old-school and prefectural riot-squad kendoka are more likely to encounter this at a noticeable level than others, but no one is immune. For avid kendoka, if your diet is fine and you feel sluggish for no other apparent reason, this may be the reason why so bring it up with your doctor if your lack of energy is serious enough to warrant medical attention, as most doctors outside of Japan and Korea have little idea what kendo/kumdo is. This kind of hemaglobinuria is certainly not a kendo-specific injury, as the condition was named after soldiers developing anemia after prolonged marching! Same goes for the metatarsal (metatarsals are the long bones in the foot) injury referred to by Sakamoto, which is also known as a march fracture, which I've had the pleasure of having. Not fun!

Anyhow, train hard and respect both yourself and your opponent.
