Muscular Hypertrophy

One Goal for Working Out is Muscle Hypertrophy:

Muscle hypertrophy means an increase in the size of muscle cells.  Weight training can increase our muscle strength as well as our muscle size.  It is best to understand what our bodies are going through in order to get the results we desire.  

The Process

Exercising a muscle increases nerve impulses that cause contraction.  This will increase our strength but will not effect the muscle’s size.  Continuing exercise causes an interaction of nervous system responses. These responses increase protein synthesis over time and the muscle cells start to get larger.  Two components must happen for muscles to grow.  Stimulation and Repair.  Contracting the muscle is when the stimulation component occurs.  Repeated contraction causes damage within the muscle fibers which puts us in our second component.  These damaged muscle fibers are then repaired, causing muscle growth.  From there, fibers are actually produced to reinforce damaged muscle fibers, adding even more growth. 

Genetic Impact

The process may never differ from person to person, but the amount may.  Each person may have a different amount they grow.  Some people tend to grow at a faster rate as well.  Our rate of growth of muscle hypertrophy is due to our genetics.  

The shape and appearance of muscle are another factor that is based from genetics.  Depending on our tendon length, we may not have the potential to have round and plump muscles.  Our muscle shape is dependent on the length of the tendons of the muscle.  Having shorter muscle tendons would mean that you have plumper muscles.
