Creatine plays a significant role in enhancing fitness and performance by increasing the availability of ATP, the energy currency of cells, during high-intensity exercise. It aids in improving strength, power, and muscle mass. Athletes often use creatine to maximize their training effectiveness, particularly in sports that require short bursts of energy, like sprinting or weightlifting. Furthermore, creatine has been shown to assist in recovery by reducing muscle damage and soreness post-exercise. Overall, creatine supplementation can lead to improved performance outcomes in both recreational and competitive athletes.
