Beta Blockers had a brief but significant part to play back in the 80s, when more than a handful of professional snooker players were found to have been taken them on a regular basis.
To understand why they were able to produce a performance enhancing effect is relatively simple. The drug is used to slow the heart rate down. Anxiety and nervousness create a rapid heartbeat. So the consequence of a BB is to increase
the length of time between beats. I have watched certain players who monitored their rate and then waited until the heart just 'boomed'. At this point the body is absolutely still and they launch their final delivery with an enhanced chance of a successful outcome.
BB had been banned earlier by Shooting authorities. Riflemen used this form of timing to pull the trigger (again using their body in the maximum stillness mode).
Prove it to yourself and you will see how it works. Then try it under pressure by shooting a tough case 9 ball for the match. You'll be soon winning a lot more matches. Let me know how you get on
Hey, Doug! Long time no read. Good to see you posting. Hope you are doing well. I've been following Fabio's activities on the tournament trail, and it looks like he's having a good run.

I take a beta blocker called Atenolol. When I first started taking it, after trying two other blood pressure meds, it make me feel odd, not alert or relaxed whatsoever.
In fact, here are the side effects of the beta blocker Atenolol:
People with high blood pressure often do not feel sick, but the medication should be taken even when you feel healthy.
If atenolol is used for chest pain, it must also be taken regularly. It should not be used to treat symptoms such as chest pain when they occur.
Your doctor may prescribe other medications, such as nitroglycerin (placed under the tongue), to relieve chest pain.
Atenolol should never be suddenly discontinued, as this may worsen heart disease or blood pressure.
Atenolol Side Effects:

Why any professional pool player would want any of these side effects does not make sense to me.
Thanks for sharing a little history of the beta blockers and snooker. You are missed around here. Come back more often. :lovies:
