Coaches and athletes are understandably confused by the mixed messages they hear and read about the value of dietary carbohydrate. Should athletes fast? Can performance benefit from ketosis? What is periodized nutrition? Is fat a better fuel source than carbohydrate? If enhanced fat burning is the key to better performance, should we care about muscle glycogen? Is carbohydrate loading necessary? Can purposefully reducing glycogen stores promote fat burning and better performance? Isn't glycogen only of concern to endurance athletes?
New research both clarifies and complicates our understanding of the importance of muscle (and liver) glycogen to not only fuel muscular activity but to promote the intracellular adaptations that are essential to improved performance. This webinar highlights our evolving understanding of the role glycogen plays in adaptation, recovery, and performance, including practical messages to help educate and guide coaches and athletes in the effective use of nutrition achieve their performance goals.
- Explain in practical terms the importance of muscle glycogen and contrast its metabolism to fat oxidation for fueling muscles during training and competition.
- Identify the current science-based recommendations for how much carbohydrate athletes should consume each day and provide three practical examples of how athletes can ensure adequate daily intake.
- Explain the role of muscle glycogen in the context of "periodized nutrition" and give at least one practical example of how purposefully manipulating glycogen stores can benefit sports performance.
