Why is glycogen important?

Glycogen is essential as it serves as the primary storage form of glucose in the body, providing readily available energy to our muscles and other tissues. It acts as a critical energy reserve, especially during physical activities where sustained energy output is required, such as running or cycling. When our muscles require energy, glycogen is broken down into glucose, which is then used to fuel muscular contractions and other cellular activities.

Significantly, glycogen storage capacity can be improved through specific training regimens and adequate carbohydrate intake. This adaptation is crucial for athletes, as increased glycogen storage can enable longer periods of exertion before fatigue sets in. Moreover, proper fueling before, during, and after workouts helps in maintaining optimal glycogen levels, facilitating recovery and preparation for subsequent exertions 1 2 3.
