muscle regeneration, replenish lost energy
Personal trainers and fitness professionals always spend countless hours reading articles and research on new methods and techniques in sports training programs, to develop and multiply muscle capabilities.
Despite this, a limited class of trainers and fitness professionals are actually aware of how muscles adapt and gradually grow in response to the increased load resulting from exercise.
In fact, skeletal muscle is the fastest-adapting tissue in the human body, and the issue of muscle hypertrophy is a fertile topic that is widely covered in research.
**********************
When the muscles are exposed to severe exertion through an exercise, such as what you are exposed to during resistance training, a direct shock occurs to the muscle fibers, which indicates an injury or laceration - according to scientific research.
This disruption of muscle cell organelles leads to the activation of a type of cell known as satellite cells that are centered on the outer end of the muscle fibers between the basement membrane and the sarcolemma of the muscle fibers, and this works. The type of cell compensates for the injury by breeding new muscle cells.
It is a biological process to replace the damaged muscle fibers, and it begins with the satellite cells where they fuse together and then fuse with the muscle fibers several times, which leads to an increase in muscle mass and its enlargement.
Satellite cells have one nucleus and have the ability to multiply by division.
And when they multiply, some of them remain as organelles on the muscle fibers, while most of them differentiate and fuse with the muscle fibers to form a new muscle protein that works to repair the damaged fibers.
Consequently, myofibrils will increase in thickness and number.
After fusion with muscle fibers, some satellite cells are used as a source of new nuclei to complete the growth of muscle fibers.
With these new nuclei, muscle fibers will be able to synthesize more proteins and form contractile muscle filaments known as actin and myosin filaments, in skeletal muscle cells.
It is interesting to note that there are large numbers of satellite cells that are associated with slow-twitch muscle fibers compared to those that revolve faster in the same muscle mass, as they regularly participate in cell maintenance after daily activities.
************
A group of hormones - or hormone-like compounds - that stimulate satellite cells to produce increases in muscle mass.
And it has been proven that these factors affect muscle growth by regulating satellite cell activity.
Hepatic growth factors (HGF) are the key to satellite cell regulation, as it has been shown to be the active agent in damaged muscle sites and may be responsible for the fusion of satellite cells at these muscle sites.
Fibroblast growth factor (FGF), another important type of growth factor that contributes to repairing muscle mass affected by successive exercises, and its role may be in regenerating blood vessels during muscular regeneration.
Research has focused on the role of an insulin-like hormone called “Growth Factor 1 and 2” (IGFs) in muscle growth, as it plays a fundamental role in regulating muscle mass growth, promoting changes in DNA to build proteins, and supporting repair and maintenance of muscle cells. .
Insulin also stimulates muscle growth by stimulating the building of proteins and facilitating glucose entry into the cell.
As satellite cells use it as fuel, the cell growth activities are thus activated.
Glucose is also included in the muscle’s energy needs.
Growth hormones also play an important role in muscle growth.
Resistance training stimulates the secretion of growth hormones from the anterior pituitary gland, and levels of secretion of these hormones depend on the extent of the muscular effort involved in the exercise.
Growth hormones also help spark the fuse of burning fat to use the resulting energy in the muscle growth process.
It also stimulates skeletal muscles to absorb amino acids.
***********************
Finally, the male hormone testosterone affects the enlargement of muscle mass, and stimulates the growth hormone response in the pituitary gland whose role we mentioned previously.
In addition, it increases the efficiency of neurotransmitters at the site of the fibers, which help stimulate tissue growth.
As a steroid hormone, testosterone interacts with the nuclear receptors on DNA, causing protein synthesis.
And it may have some regulating effects of satellite cells
