What I think really stinks is that how does anybody really know BCAA’s are doing anything for them?
Unless your are at the peak of your genetic potential I don’t see how it is possible to feel that it is working. [/quote]
I get what you’re saying. Most people who “feel” supplements working are morons. “Man, I popped a hand full of BCAAs and am totally pumped! Time to shadow box in the gym!”
But I’ve been on a sub 2,000 cal low-diet with and without in-between meal BCAAs. I feel less like shit. When on a diet, additional BCAAs help with recovery: I feel less sore. These are subjective feelings, of course, but I’m not sure that it means they are invalid.
As an experiment, I told my friend after his workout: “Take these pills” and gave him 10 grams of BCAAs. He didn’t know what they were.
The next day he said: “Hey, were those pills you gave me supposed to help with recovery? Because I’m a lot less sore today than I usually would be.”
Lots of things are measured based on subjective factors. Pain is subjective. Imagine if someone said: “How can you know if a pain reliever works when all of these freaks are just reporting their subjective feelings with this.” Of course, there is always the placebo elephant in the room. But saying that you can’t base things on feelings is quite different from saying those feelings might be influenced by the belief that whatever you are taking will lead to result x.
My life is generally the same week-by-week. Unless something really drastic happened (like my dad died or I lost a major source of income), I wouldn’t have any more or less stress in my life.
I think most people have a lot of “sameness” in their lives. So you can often pin down cause-and-effect.
So if I start Supplement X and notice I can do two extra sprints, I can rationally attribute that the Supplement X.
While it’s true man does not live in a vacuum, most of our lives are pretty stable on a week-by-week basis.
