what's superior? marquez had some proven results with that hyperbaric chamber.... jury's still out on floyd's subzero bs....
Subzero bs? Cryogenic chambers have been used by professional sports teams for a couple of decades. Its not some new fangled invention. Its essentially a scientific step up from the old ice baths that people used to get into after training
PEDs are the best method of enhancing performance - it is a game changer. You can't compare a hypobaric chamber to cryogenic cooling. They are two completely different things and do completely different things. Cryogenic & oxygen treatments are usefull recovery methods/tools. I wouldn't say they could help either men win this fight. hypobaric and high altitude training methods are usefull in improving cardiovascular fitness however the effectiveness in improving performance is hard to quantify. It's all down to the physiology of the person...it could actually do more harm than good. Stick Floyd or Pac at high altitude 2 weeks before the fight it would screw them over. Blood doping is probably the best illegal method of performance enhancing either of these two could use to gain an advantage over one another.
