What happens to glycogen storage as a result of training?

As a result of training, glycogen storage in the body typically increases. Regular aerobic and resistance training enhances the muscles' ability to store glycogen, a form of carbohydrate that serves as a vital energy source during physical activity. This increased storage capacity occurs because with consistent training, the skeletal muscles adapt by enhancing their glycogen synthesis pathways and increasing the number of enzymes that facilitate glycogen storage. Additionally, the muscle fibers themselves can increase in size and number, providing more space for glycogen storage.

Overall, as fitness levels improve through training, the body becomes more efficient at utilizing and storing glycogen, allowing for sustained energy availability during prolonged exercise. This adaptation contributes significantly to an athlete's endurance and performance.
