Document Summary
Cho intake during performances: over the first 30 mins - 1 hour there is not much difference in peoples abilities to performs (despite the fact that one group is ingesting cho regularly and other group isn"t) Start to observe change around 60-90 mins: people will be able to sustain or level up power output when ingesting cho (cho conserves muscle glycogen because they have available glucose coming from blood) Later portion of that particular activity session is where you"re going to see the greatest differences between the 2 groups: also applies to continues and intermitted (exc. Soccer, hockey) exercises: 1tsp of sugar= 4 grams of cho. If you take cho every 15 mins throughout exercise stamina is going to be improved. If you take in cho every 15 mins or so during exercise you can maintain blood glucose levels. Glycemic index: how quickly a particular food is being absorbed, glucose has highest absorption rate.
