FIFTH PART
I was planning five chapters to deal with triathlon physiology. I will extend myself with different titles. I already used different titles in previous writings.
Scott Tinley, a man that started triathlon training and went beyond the limits of training in the 80’s to improve performance, gives a good recounting of what could happen if one does not follow a plan to improve. This was an interview at the end of his career. Inside triathlon magazine, volume 15, June: 2000:
“You have alluded that there have been a lot things going wrong with your body in the past four years. What have they been?
I think I compromise in number of different systems in my body—my pituitary-adrenal axis and my hormonal system. And my emotional state—because of depleted neurotransmitters.
What are some of the signs of these depleted states?
When you exercise cortisol increases because is a parasympathetic stimulator –fight or flight. You want your cortisol to go up…My cortisol level was already elevated. A normal person is 8 to 9 –mine was 13 at rest…We did tests at the Olympic Training Center and found that my cortisol production dropped during an eight-mile-run (20).
Our memory can help us or kill us. But let us go back to basics. I copied this research from:
Wilmore, J.H., Costill, D.L., & Kenney, W.L. (2007). Physiology of sport and exercise. Champaign, IL: Human Kinetics.
We start with questions about what we see from this serious research. How long the cortisol is going to be up to hit the body once again to produce GH? It depends on the intensity of the training and the athlete´s level of training. But six hour is enough for most of the high performance athletes. This way we can produce more GH with another hit to the body. Some research tell us not to wait so long, because the longer you wait after a hard work out the higher the cortisol increases. We have not done cortisol testing on our athletes. We have empirical research based on performance. Remember, it does no matter what you produce as hormone if your technique and specifically your cadence is not adequate for what you expect as performance. “Practice as you compete and compete as you practice.”
Exercise is a stress, and cortisol, often called the "stress hormone" is produced in response to stress. The longer you exercise, the more cortisol you produce, and the production is increased the longer you rest between exercises. Keeping your rest periods short can limit your body's ability to produce cortisol. One of the functions of cortisol is to break down proteins for amino acids, and large concentrations of cortisol will scavenge muscle tissue for any amino acids your body may require…
Your production of growth hormone can be increased with exercise, but again only with heavy exercise. Rest periods play a larger role in the stimulation of growth hormone, so by keeping your volume and intensity high and your rest periods under 90 seconds, you can increase your production of this hormone.

I would not keep kicking a dead horse but knowing consequences and how to improve training is important, and cortisol places an important part in it. As I said previously: Do not forget that there are many variables in training and we should know most of the them to have an edge over competitors.
