General Review of Test Elements
Cortisol, DHEA (dehydroepiandrosterone), and testosterone are all hormones that play essential roles in the body, including influencing athletic performance, recovery, and overall fitness. By examining the levels of these hormones, researchers and sports professionals can gain insights into an individual's physical fitness and ability to perform in various sports.
Cortisol:
Cortisol is a steroid hormone produced by the adrenal glands, often referred to as the "stress hormone." It is essential for maintaining various bodily functions, including blood pressure regulation, immune response, and metabolism. However, when it comes to sports fitness, cortisol is mainly known for its catabolic effect, meaning it can break down muscle tissue and inhibit muscle growth. High cortisol levels can indicate physical stress, overtraining, or inadequate recovery.
