hyperbaric chambers is equivalent to blood-doping. What do people think?
I can see how it might possibly be of value to some unperfused injury or something, but surely for cyclists the effect of spending time in higher oxygen concentrations would be to lower Hb? The opposite of spending time pre-season at high altitude, which increases blood haemoglobin.
I know little about it but I would have thought there would be the potential for adverse effects, oxygen being toxic at higher concentrations.
Pure idle speculation on my part, I haven’t even bothered to Google it.
