Hypertrophy
The increase in muscle fiber size caused by overload and protein synthesis.
What is muscle hypertrophy?
These tiny structures are added to muscle fibers during stretch overload.
What are sarcomeres?
This factor helps determine whether muscle fibers become slow-twitch or fast-twitch.
What is mechanical strain?
Mechanical overload such as resistance training or stretching.
What type of stress usually causes hypertrophy in muscles?
This process rapidly increases during hypertrophy to help muscles build proteins.
What is protein synthesis?
This cellular structure helps muscles sense mechanical stress.
What is the cytoskeleton (or dystrophin complex)?
Because cells increase protein synthesis and repair damaged fibers, making them thicker and stronger.
Why do muscles grow larger after repeated overload?
This growth factor is strongly linked to muscle repair and adaptation during overload.
What is Mechano Growth Factor (MGF)?
This process converts mechanical stress into chemical signals that activate genes for muscle growth and repair.
What is mechanotransduction?
