|
|
|
What type of exercise time limit would your PC stores allow?
|
10-15 seconds (tennis rally) (power output 8.6)

|
|
What would be the best type of pregame meal?
|
One that is mild and easily digested.
|
|
|
In rapid glycolysis, why is fatigue inducing pyruvate used?
|
It does induce fatigue, but its synthesis produces NAD, which is necessary for glycolysis to continue!!!! (This would obviously induce "fatigue" more!!
|
|

90-120 Minutes (Marathon) (power output 2.7)
|
|
|
What is the physiological reason behind "hitting the wall"?
|
You have depleted your muscle glycogen stores.
|
|
