Yeah beta blockers are great, they make you cool as a cucumber.
they're banned as performance enhancing drugs for this reason, there was widespread use in 8 ball snooker etc to stop adrenaline on big shots.
I've written about it before, but I read some interesting things about beta-blockers and PTSD. If you take a beta-blocker fairly immediately after a traumatic event they may block traumatic events from "setting" in your memory. This could be used on soldiers in combat situations etc, but it raised some ethical concerns wrt to soldiers sort of becoming killing machines who pay no price for it.
Anyone here really up on training for cardio fitness? I've never read up on it and I'm sure there would be a lot to wade through. What I'm wondering is what kind of intensity, duration and frequency is required for improving your cardio? How quickly do you get results? What I have seen is mentions on how it needs to be done at a certain intensity to get something out of it.
I did see some science program that said a certain percentage of people get no improvements from any cardio regimen. The host of the show was told he belonged to this group after a genetic test and was told he would likely not improve his cardio parameters through training
