During physical exertion, muscles require vast amounts of energy to sustain contractions. NAD+ plays a crucial role by ensuring efficient ATP production. This is essential not only for immediate energy needs but also for sustaining prolonged periods of activity, contributing significantly to endurance. Athletes with higher NAD+ levels are known to experience reduced fatigue, enabling them to push harder and recover swiftly.
Muscle Repair and Recovery
Post-exercise, NAD+-dependent pathways are activated to manage muscle recovery. This involves the autophagolysosomal system, which breaks down damaged cellular components, and regenerative processes such as satellite cell proliferation. These processes are critical for muscle repair and growth, helping mitigate muscle fatigue and enhancing recovery.
Metabolic Efficiency and Muscle Protection
NAD+ also enhances metabolic reactions that regulate the cell cycle and energy usage during muscle activity. Efficient metabolism ensures optimal substrate utilization, crucial during intense trainings [1]. Moreover, NAD+ provides protective benefits by enhancing muscle function and shielding against exercise-induced damage. This protection helps maintain muscle integrity and capacity[2].
