Hardening of the arteries, also called atherosclerosis, occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques. Over time, these plaques can block the arteries and cause problems throughout the body.
CNS fatigue (CNS = central nervous system) is a slightly more convoluted phenomenon, but the term is thrown around frequently in the world of fitness. By itself, the acronym evokes notions of frailty, complication, and extreme caution.NS fatigue (CNS = central nervous system) is a slightly more convoluted phenomenon, but the term is thrown around frequently in the world of fitness.

Fatigue in the muscle itself is referred to as peripheral fatigue while fatigue at the point of origin is known as central fatigue. We're all familiar with peripheral fatigue and what to do about it-proper nutrition, supplementation and allowing sufficient time for recovery between training sessions.he theory is the high 5-HT/low Dopamine brings on CNS Fatigue with low 5-HT/high Dopamine resulting in enhanced performance. That is really good news because proper training, nutrition and supplementation can help manage Serotonin/Dopamine levels in our brains.
