Greg Doucette calls out US Olympic team for 'doping' in Paris - "It's happened in US & Canada" 

IFBB Pro coach Greg Doucette has gone all out while reacting to a YouTube video whose theme and sole goal appears to be clarification. He has falsified the claims and justifications given in the video 'Why Swimmers' Faces Are Turning Purple at the Paris Olympics' by @FaresKsebati on YouTube.

Ksebati is a swimming coach-turned-entrepreneur and a TedX speaker who recently reacted to the US Olympic swimming team's faces turning blue in Paris.

Doucette also called out the US and Canadian anti-doping agencies for secretly allowing their Olympic teams to use undetectable substances in their blood.

"Sometimes the countries do not even report the athletes that failed the dope test. That has happened in Canada, it's happened in United States," he said (9:22).

When a child is doing activities like playing and swimming, their face becomes pink due to the blood rushing. But if it is any shade of blue or purple - it shows the lack of Oxygen. The color of deoxygenated blood is in the violet-blue-green range, as Doucette continued to cite what was actually happening:

"Normally, your blood Oxygen saturation is perhaps close to 100%. May be 98% and so. But during this race, you're clearly swimming faster than last time, you're holding breath underwater, so that goes down." (5:22).

But this appeared to be not-so-normal to the coach as he continued:

"But if you're not on drugs, it doesn't go down so much that you're gonna turn blue." (5:31).

"That is a definite sign they could be using ITPP, or they're doing blood doping."

What is blood doping? Does it make one turn violet?

Greg explained how blood doping is done. One has to take out a small volume of their blood a month or so before the event or competition. They then have to inject it back into the body right before going in. The blood has to be kept under refrigeration during this time.

The injected blood is going to contribute to the total hemoglobin in one's body, per unit of blood. The normal value of hemoglobin in blood is 14g/dL (12-16 g/dL for females, 14-18 g/dL for males), with an optimum Oxygen saturation of 98%.

When blood doping happens, the critical blood oxygen level one needs to survive comes down to 87%. Doucette stated in the same video:

"ITPP reduces the affinity of Oxygen for hemoglobin." (7:19).

ITTP is a performance-enhancing substance that is prohibited for athletes. Sadly, as of now, its presence cannot be detected in human urine. This clearly makes it a preferred choice over the drugs that can be detected or have well-recognizable symptoms.

"Their whole body looks nice and tan with their six packs but their faces are blue and purple," Doucette said (7:55).
