How Muscle Actually Grows
What actually tells a muscle to grow, and what only feels like it.
-
Skeletal muscle
Skeletal muscle is the striped tissue attached to your bones that contracts to move your skeleton and keep your body upright.
-
Muscle Hypertrophy
Muscle hypertrophy is the enlargement of skeletal muscle caused by individual muscle cells growing thicker rather than multiplying.
-
Myosatellite cell
A myosatellite cell is a dormant stem cell nestled against the outer edge of a skeletal muscle fiber.
-
Progressive overload
Progressive overload is the training principle of gradually increasing the stress placed on your muscles and nervous system.
-
Muscle Soreness
Delayed onset muscle soreness comes from lengthening muscles under load, not lactic acid.
-
Protein (nutrient)
Protein breaks down into amino acids to build tissue and enzymes.
-
Creatine
Creatine is an organic compound that your body uses to rapidly recycle ATP, the molecule cells consume for energy.
-
Sarcopenia
Sarcopenia is the progressive loss of skeletal muscle mass, strength, and function that happens with aging or prolonged immobility.
