The most researched ergogenic aid: phosphocreatine kinase dynamics, intracellular osmotic swelling, satellite cell proliferation, and 5g daily dosing.
Creatine Monohydrate saturates skeletal muscle phosphocreatine (PCr) stores, speeding ATP replenishment during high-intensity 1-to-10 rep resistance sets.
1. Ergogenic Mechanisms of Action
Rapid ATP Donation: Phosphocreatine donates its high-energy phosphate group to ADP via creatine kinase, allowing 1–2 additional high-load repetitions.
Intracellular Osmolality: Draws water into muscle myocyte sarcoplasm, creating cellular swelling that activates anabolic mechanotransduction signaling.
Satellite Cell Activation: Increases myogenic regulatory factor expression (myogenin, MRF4) to promote satellite cell fusion with existing muscle fibers.
