Hi-Lo training is far superior in one respect -- it is WADA approved.
My unconditional advice remains if you want to increase your RBCs, go to altitude.
A couple of things here: Wasn't Jama Aden and his athletes at an altitude training camp at Sabadell, Spain (2016) when the hotel was raided and a bunch of EPO was confiscated? So, the question is that if altitude increases your RBCs, then what was the EPO going to be used for? If there's a limit on the increase of RBCs, Hct, Hgb, etc. - depending how high and how long an athlete is at that particular altitude, maybe the objective here was to increase blood values above & beyond what altitude could do at Sabadell. And just as important, perhaps interfere with the rEPO testing assay. Remember not one single athlete tested positive at the Sabadell raid.
Secondly, many athletes and their coaches don't want to train at altitude or don't have the logistics for it. In these cases, dopers will want to use EPO or blood transfusions and get the same or better benefits of training at altitude (altitude training costs $$$ - traveling, lodging, fees, etc.). Remember "Operation Aderlass" that involved cyclists & XC skiers? A lot of athletes, particularly the XC skiers, resided near areas of higher altitude to train at but instead resorted to blood doping - and what a remarkable operation that was! Athletes withdrawing blood sometime in the off-season and then reinfusing the morning of the competition. Then immediately after competition, the athlete would have the same amount that was reinfused withdrawn so as to not affect the ABP.
Simply ingenious - and if it wasn't for a whistleblower (disgruntled athlete) who went to the Austrian police authorities, this operation would still be going on full speed.
Realize rekrunner there's a lot of O2-vector doping going on in endurance sports - I imagine we don't know the half of it, and probably never will.
