How Creatine REALLY Works - The Biology Behind It

The video explains how bodybuilders use creatine for energy and muscle growth. It covers muscle contraction at the cellular level, focusing on sarcomeres, myosin, and actin. ATP is crucial for muscle contraction, acting as the body's energy currency. The video details ATP's role, its hydrolysis into ADP and inorganic phosphate, and the powerstroke mechanism. Creatine supplements help replenish ATP by converting ADP back to ATP, enhancing energy supply during exercise. The video also touches on creatine's effects on water retention and muscle growth hormones.
