Muscle Anatomy and Function


Sarcoplasmic Hypertrophy is muscle growth that comes from increasing the amount of sarcoplasm inside a muscle fiber. Each muscle fiber is made up of sarcoplasm and myofibrils. The sarcoplasm is a fluid that contains things like glycogen (stored carbohydrates), water, ATP (energy source), minerals (like calcium), fats, and oxygen-binding proteins […]

Sarcoplasmic Hypertrophy


Myofibrillar Hypertrophy is muscle growth that comes from the myofibrils (inside a muscle fiber) growing in size or increasing in number. Each muscle fiber is made up of chains of these myofibrils surrounded by a fluid (called sarcoplasm) that contains things like glycogen (stored carbohydrates), water, ATP (energy source), minerals […]

Myofibrillar Hypertrophy


There are generally three different muscle fiber types that can make up the individual skeletal muscles in the body. Knowing the different muscle fiber types can help with understanding a certain muscle’s primary function and therefore how best to train the muscle for a particular goal such as strength, growth, […]
