Hormones are our couriers that prompt specific regulatory responses of certain cells or organs. They are crucial in every single biological activity in the human body. For bodybuilders they are vital for the growth and development of lean muscle mass. They also influence sleep, metabolism, tissue function, behavior and mood.
Anabolic hormones are the most crucial muscle building hormones. On the flip side we have catabolic hormones that also are active and at work. When we are talking about exercise this applies to the breakdown of stored energy to fuel the activity, as well as the breakdown of food and supplements into amino acids, fatty acids and glycogen. These nutrient building blocks are then absorbed into muscle cells to help fuel working muscles, as well as repair and rebuild the structure.
Catabolic hormones can also breakdown muscle tissue and ultimately reduce the gains you make in the gym. Due to this catabolic process it is crucial that you have a basic understanding of all the hormones that relate to bodybuilding and muscle development. These hormones have a complex interrelationship releasing a hormonal tidal wave that has multifaceted effects on the body.
