That was going to be my WAG. Low testosterone can lead to fatigue, reduced energy levels, and memory / cognition issues. Thus, someone who needs to be able to be awake and mentally sharp for extended periods of time would want the opposite.
Besides avoiding the effects of fatigue there’s the off book uses of a stimulant like Ritalin. It’s generally seen as helping focus attention even in those that don’t suffer from ADHD. I could see someone using it to try and improve their mental focus for bridge.
It speaks to a controversy in the bridge world which is the various governing bodies trying to get recognition from the Olympic bodies as a mind sport, hence the PED issue. The controversy arises from many players seeing these efforts as a joke and a huge waste of time and resources [I don’t actually know any player who thinks it’s a good idea but obv they are out there].
I believe the list of prohibited substances is not compartmentalised between physical and mental sports [could be wrong on this]. So you have this ridiculous situation like Helgemo’s where a drug banned mainly for it’s performance-enhancing effect on young power athletes is leading to a suspension for a 60 year old bridge player. And vice versa, there are mental stimulants that are legal to take because no one is interested in them for the real Olympics.
Caffeine is the big one - massively well-documented performance-enhancing qualities for both physical and mental activity, but it would be tough to ban coffee!
But Clomid and other estrogen boosters are common things to be busted for in MMA. They are used to restart endogenous testosterone production after you come off a cycle.
Again, possible, but I doubt Brock Lesnar is transitioning, and he was busted for the same thing in 2016.
And, uh, third, why do they drug test - with the expensive tests that can pick up hormones - bridge players? Contrary to some popular belief, the regular drug tests that employers order and even the military has performed only test for commonly abused drugs. (cocaine, marijuana, heroin, meth) (as a side note, this is why soldiers can use steroids and obviously most units the commander isn’t going to order the far more expensive test unless a juicing solder is actually causing discipline problems with roid rage)
It costs over $500 to test for things like these hormones this athlete was busted for.
Since professional bridge abides by World Anti-Doping Agency rules, there are consistent testing procedures and a specific list of banned substances. Presumably they just go by the official list.
From what I understand, being functionally married to someone who takes a version of Concerta, ADHD drugs really don’t improve concentration for those who don’t suffer from attention disorders. The reason attention disorders exist is that the part of the brain that handles attention fires at a far slower pace for those with disorders than ones that don’t have it. The effect on people who’s attention centers are already working normally is negligible in that respect.
However, what they will do to those without ADHD is work as a long term time-release stimulant that avoids the cycle of up and down that can happen when mainlining caffeine. They also tend to result in a slower come down when they wear off, rather than resulting in a “crash” effect as is common with caffeine. So you basically have a drug that is more effective than caffeine and almost as safe.
