Creatine plays a key role in sports performance by providing a rapid source of energy during high-intensity exercise. It helps replenish ATP (adenosine triphosphate), the primary energy currency in cells, allowing athletes to perform better in short bursts of activity, such as sprinting or weightlifting. Creatine supplementation can enhance muscle strength, power, and recovery, making it a popular choice among those engaging in strength and explosive power sports. Its benefits are particularly noticeable during intense training sessions.
