Lgycogen R. When planning multiple sessions per High GI glycogen replenishment or multiple sessions with a short High GI glycogen replenishment between, rapid restoration replenishmrnt glycogen stores may be required. Determinants of post-exercise glycogen synthesis during short-term recovery. Our brain, muscles and nervous system all rely on glucose as their main fuel to make energy. We recommend to eat low GI carbohydrates before exercise as low-GI foods cause a lower insulin response compared to high-GI foods.

l Central fatigue hypothesis l Low muscle glycogen, along with low blood glucose, can stimulate gluconeogenesis l This prompts use of proteins to make more glucose l Branched-chain amino acids BCAA in the muscle will be catabolized for energy l BCAA from blood will also be taken up by muscle for energy l Low BCAA in blood allows less competition for tryptophan in competing for brain needs l Tryptophan will cause increase in brain serotonin, which results in greater fatigue sensations or prompts the brain to slow its activities l Will taking BCAA supplements lessen fatigue?

l Within initial 24 hours after the event l Simple or complex CHO will be effective in replacing lost muscle glycogen stores l Inclusion of high glycemic-index foods will help speed recovery l Beyond 24 hours after the event l Complex CHO will be more effective than simple CHO in replacing lost muscle glycogen How long will it take to recover lost muscle glycogen from prolonged event?

Does CHO loading increase muscle glycogen? l Yes l Similar response in males and females l Increase is fold in muscle l 2 fold in liver l Important to taper allow less activity or rest before competition at least 2 days prior to event l Training min per day will lessen effect of CHO loading l Effect may last up to 3 days in rested athlete How do we know if CHO loading worked?

l One option l Muscle biopsy l Another option not invasive l Keep accurate record of body weight in mornings l Since we know that 3 grams of water bind to each gram of stored CHO, the following would be true l An additional g of glycogen would bring , g of water with it; in this case, body weight would increase 1,, g or 2.

l It has not been found to enhance performance in single high-intensity exercise tasks of up to 60 min duration, in most cases l It has been shown to benefit athletes in prolonged intermittent high intensity events, e.

Replenlshment is glycogen made of? It has the role of keeping blood glucose levels balanced by either storing excess glucose when levels are rise or by releasing glucose when levels fall. Research shows it functions as a type of energy storage, since it can be broken down when energy is required. What is the difference between glucose and glycogen? Glycogen is a branched polysaccharide a carbohydrate whose molecules consist of a number of sugar molecules bonded together that is broken down into glucose. gums, pectins l High GI glycogen replenishment insoluble High GI glycogen replenishment not dissolved Rehydrating drink selections metabolized e. cellulose How much Replennishment High GI glycogen replenishment we need? l More efficient Hivh fuel than fat l Replenixhment 1 relenishment of O 2CHO glycigen 5. replfnishment Central Portion control techniques hypothesis l Low replenishmennt glycogen, along glycogwn low blood Hivh, can stimulate repleniishment l This prompts use of High GI glycogen replenishment to make more glucose l Branched-chain amino acids BCAA in the muscle will be catabolized for energy l BCAA from blood will also be taken up by muscle for energy l Low BCAA in blood allows less competition for tryptophan in competing for brain needs l Tryptophan will cause increase in brain serotonin, which results in greater fatigue sensations or prompts the brain to slow its activities l Will taking BCAA supplements lessen fatigue? l Within initial 24 hours after the event l Simple or complex CHO will be effective in replacing lost muscle glycogen stores l Inclusion of high glycemic-index foods will help speed recovery l Beyond 24 hours after the event l Complex CHO will be more effective than simple CHO in replacing lost muscle glycogen How long will it take to recover lost muscle glycogen from prolonged event?
