> I find the anticipation of a race provokes anxiety although not in the same league or nature of social anxiety. Running stress is predictable and the anxiety can be funnelled into physical effort. It is logical and expected. Social anxiety and panic are unfair. There is no where to dissipate the adrenaline...you just sizzle and fry in your own juices and then go on to worry about it happening the next time.

> sabreI didn't know tyrosine had that effect, and I'm impressed at how well you were able to define it. Tyrosine reduces both heart rate and blood pressure, but reports have it that it increases endurance.
It's anxiolytic properties are probably related to reductions in sympathetic tone. It looks like this works well for you, but if you feel that it interferes with your workout intensity, by all means take it afterwards. It's a good idea to take it with some simple carbs to avoid any excessive reduction in heart function, post exertion.
