In other words, myofibrillar hypertrophy leads to a greater density of the contractible myofibrils which increases the ability to exert strength and is best accomplished by training heavy weights with low reps, and sarcoplasmic hypertrophy is an increase in the volume of the non-contractible muscle cell fluid
called sarcoplasm (which makes up to 30 % of the muscle's size), doesn't lead to an increase in muscular strength and can be achieved by performing high - rep, low - load training.
They occur as a result of the running blood and nutrients into the non-contractile part of the muscle cells also known
as sarcoplasm.
This is a fast way to increase the size of a muscle, but
since sarcoplasm is a fluid and can't contract... it won't make the muscle significantly stronger.
I've also noticed through additional research that it may primarily be an increase
in sarcoplasm that is creating the size increase.
The first one is
called sarcoplasmic hypertrophy and it represents an increase in the non-contractile muscle cell fluid, called sarcoplasm.
High reps will cause sarcoplasmic hypertrophy, which means that you'll get an increase in volume of the non-contractile fluids of the muscle,
the sarcoplasm.
You won't get a lot stronger either.The bad news here is that
sarcoplasm is only about 25 % of the muscle mass, or in other words — you'll get a little bigger and bloated but not toned or defined.
Essentially, you achieve expansion of both the myofibrils and
the sarcoplasm, the energy fluid in muscles that expands in response to long tension times.
The sarcoplasm consists of nutrients, glycogen, capillaries, and mitochondria proliferation.This type of hypertrophy is mainly a result of high rep, high frequency «bodybuilding - type» training.
Sarcoplasmic Hypertrophy is an increase in the muscle cell fluid (called
sarcoplasm) within the muscle cell.
-- Sarcoplasmic hypertrophy, which focuses more on expansion of
the sarcoplasm inside the muscle.
Sarcoplasm is the plasmic parts of muscles cells that include proteins, glycogen, water, collagen and other substances.
Sarcoplasm is a fuild and myofibrillis are little rods that help the muscles contract.
Sarcoplasmic hypertrophy is an increase of
the sarcoplasm and other non-contractile proteins within muscle cells and is primarily induced by lifting light loads for higher reps.. This type of growth, although not typically accompanied by any strength gains, is the primary reason why bodybuilders tend to be more muscular than strength and power athletes.
Muscle is composed of viscous (
sarcoplasm), elastic (muscle filaments) and nonelastic (connective tissue) fibers.
