Thread: How much of an effect does stress have on recovery/muscle gain?

stress raises cortisol levels.

Cortisol is a steroid hormone made in the adrenal glands, which are small glands adjacent to the kidneys. Among its important functions in the body include roles in the regulation of blood pressure and cardiovascular function as well as regulation of the body's use of proteins, carbohydrates, and fats. Cortisol secretion increases in response to any stress in the body, whether physical (such as illness, trauma, surgery, or temperature extremes) or psychological. When cortisol is secreted, it causes a breakdown of muscle protein, leading to release of amino acids (the "building blocks" of protein) into the bloodstream. These amino acids are then used by the liver to synthesize glucose for energy, in a process called gluconeogenesis. This process raises the blood sugar level so the brain will have more glucose for energy. At the same time the other tissues of the body decrease their use of glucose as fuel. Cortisol also leads to the release of so-called fatty acids, an energy source from fat cells, for use by the muscles. Taken together, these energy-directing processes prepare the individual to deal with stressors and insure that the brain receives adequate energy sources.

Stress is the most important factor in the development in both hypertrophy and strength. You have 2 basic forms of stress, one is negative and the other is positive. Positive stress happens in the gym if one understands training and ways to manuplate positive stress, negative stress is things that are detrimental to the individual in either the gym or in every day life.

You can find out alot more on the principle of stress and the bodies adaptive abilities by looking up the GAS principle.

I believe that he was asking about that kind of stress.

fvck.

I think ive finally discovered why my gains have been coming so slowly.

How much of an impact do you think elevated cortisol levels would have on training?

I'm thinking of getting a test done to see if this really is the case for me - theres a company called "Metamatrix" that does testing for it.

I've learned along time ago its effective to learn both sides of things inorder to fully understand the big picture.

It would have a very big impact. A lack of sleep can also lead to higher cortisol levels. Another symptom of high cortisol levels is the accumulation of fat around the midsection.

Stress IMO is crucial in terms of your muscle gain / fat loss. Simply because like Prince stated stress raises a very catabolic horomone in our bodies called "cortisol." Cortisol is pretty much the LAST horomone that we want raised in our body. Causing extreme catabolism (muscle wasting) when elevated for long periods of time. Do your body a favor, and keep your stress level low.

I learned a long time ago to read questions and answer with the correct response.

Thats fine. I've also learned along time ago from my mentor that you should always furthur the education of others and yourself. The question was answered with extra information about the topic.

Btw, you might also wanna read a bit more, the article you posted was in regards to cortisol in the blood. There are many more byproducts from stress. That thread didnt even mention neural fatigue, external stress and more.


Kc

So I guess a good question would be..how would one reduce or get rid of stress? Aside from avoiding stressful situations of course.

Vodka.

Can you explain how the other stress byproducts can affect training?

Actually if you go to google and type in "overreaching" you should get some pretty good documents discribing both overreaching and overtraining. All programs should be designed to overreach.
