MUSCLE GROWTH PHYSIOLOGY BY ANABOLIC STEROIDS

Growth physiology 1

Medifit Education explains in brief the exact physiology of Muscle growth, when anybody is on Anabolic steroids.

This physiology explained is only related to Anabolic steroids use for Muscle building or to prevent body wasting after long term illness.

Some examples of the anabolic effects of these hormones are increased protein synthesis from amino acids, increased appetite, increased bone remodelling and growth, and stimulation of bone marrow, which increases the production of red blood cells. Through a number of mechanisms anabolic steroids stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles, leading to increased strength.

 

Brief exposure to anabolic steroids may have long lasting, possibly permanent, performance-enhancing effects, shows a study published today in The Journal of Physiology.

Previously, re-acquisition of muscle mass – with or without steroid use – after periods of inactivity has been attributed to motor learning. However, this new data from the University of Oslo suggests that there is a cellular ‘memory mechanism’ within muscle of brief steroid users.

The team investigated the effects of steroids on muscle re-acquisition in mice and discovered greater muscle mass and more myonuclei – which are essential components for muscle fibre function – were apparent after returning to exercise.

“Mice were briefly exposed to steroids which resulted in increased muscle mass and number of cell nuclei in the muscle fibres. Three months after withdrawal of the drug (approximately 15% of a mouse’s life span) their muscles grew by 30% over six days following load exercise. The untreated mice grew insignificantly.”

The findings might have consequences for the exclusion time of doping offenders as brief exposure to anabolic steroids might have long lasting performance-enhancing effects.

Steroids are derived from the male hormone called testosterone. This leads to the growth of muscle as the male hormone increases the number of receptors on the muscle tissue. These steroids enter body cells and stimulate the production of protein. This fabrication of protein is used for the repairing and developing of muscle tissues. Apart from muscle building, steroids help in quicker recuperation from infections and sicknesses. This is because additional production of protein allows rapid restoration of the body.
