Kinesiology 110 Spring 2009 Barry Braun, PhD Lecture 13 questions 1. What is the “critical window” for glycogen storage (repletion)? - Since the great majority of exercise energy comes from the use of CHO, there is a big need to replace stored CHO after exercise - Refill muscle and liver glycogen stores (MAJOR GOAL) - When should you eat to replace the lost CHO? o Replenish glycogen storage to allow recovery for next bout of exercise - There is a “critical window” in which the enzyme glyocgen synthase (responsible for glycogen synthesis) is particularly active 2. Why is more glycogen stored if carbohydrates are eaten within this window? o Glycogen synthase is very active for about 2 hours after exercise - Consuming CHO in the first 2 hours after exercise can optimize the replacement of muscle glycogen 3. Does the form of the carbohydrate matter in terms of its impact on glycogen repletion? What kinds of carbohydrates work best?
