Q: Should we really be worried about cortisol? If so, how can we decrease it?
A: We should be worried about cortisol, and not just because of its catabolic effects on muscle. For one thing, the overproduction of cortisol has been linked to brain aging.
If you run on cortisol for too long, it will actually shrink the hypothalamus, the vital part of the brain for memory. By the way, athletes who produce the highest amount of cortisol — which are rowers and cross country skiers — also have a high incidence of Alzheimer's.
Cortisol is a double-edged sword of a hormone. You need it for energy, but if you have too much it can break down tissue. Morning is a good time to have cortisol; it's basically what wakes you up and gets you going. But people who've been stressed for too long have what they call "low morning energy." They push the snooze button fifty times. That can be a sign of low cortisol.
Your cortisol should be high in the morning and low at night. When people get stressed this tends to reverse: low in the morning and high at night. After a while it's low all the time; they have low energy and depression.
But it's well documented in the literature that the less cortisol you have and the more anabolic hormones you have, the more progress in the gym you'll make.
Is cortisol controllable? Yes. The post-workout drink is your basic tool to control cortisol produced by training.
remarque : il dit ça parce que t-nation vend un post-corkout drink. Je pense que boire des hydrates avec un peu de BCAA+leucine pendant le trainign est un meilleur moyen de limiter la hausse de cortisol
Anything that will mitigate how much cortisol you produce in a day will make a big difference. For example, just seven grams of fish oil a day has been shown in a French study to mitigate the amount of stress hormones a person produces. Rhodiola rosea and Siberian ginseng, which are known as adaptogens, can help mitigate cortisol as well.
Interesting note: Wales, Ireland, and England have the highest rates of depression in the world, and they also have the highest levels of omega-3 deficiency. Omega-3 raises serotonin in the brain. There have been over 600 studies coming out on depression and omega-3s in the last two years alone. So, yet another good reason to use fish oil.
