having a small child who doesn't sleep all night.
-
12 hour shifts and not enough sleep
-
Smoking to many cigarettes before I bat
-
g/f poking u in the side for snoring every hour lol

8 pints of the black stuff, 20 benson and a bucket of dry roasted should do the trick

Being middle aged and overweight!!!

1. Lactic acid build up
2. dehydration
3. Glycogen depletion
4. reduced rate of atp synthesis
5. low calcium levels
6. low levels of ach
7. Overheating (thermoregulation!)
i guess thats what they'll be after if its sports course, as thats what my a level pe was :) shocked i can remember!

Surely 1, 2, 3 and 7 are symptoms of doing something else? Scoring a double hundred? Running a marathon in 25 celsius heat, bowling twenty overs in the west indies, etc...

not understanding tim?
those are the 7 always given...

Maybe, but you get Lactic Acid build up from running 20 odd miles, so they aren't really the causes of fatigue, just the initial symptoms that you are likely to end up fatigued because, surprise surprise, running 20 odd miles is really hard! Funnily enough, that's also the point at which you generally find that you hit the wall, which is caused by glycogen depletion because you have exhausted your supplies by, yes you guessed it, running 20 odd miles!
I know I'm playing Devil's Advocate, but the root cause of the fatigue is not the list, it's the activity that causes the list in the first place!
-
but you could go to such a molecular level with it all, as everything is caused by something. Lactic acid isnt a symptom, its a cause, as lactic acid fatigues you, not you get fatigued and then get lactic acid.
The other way of looking at it is to name every activity in the world you could get fatigued from, which it certainly isnt that, as its pretty muh anytihng in the world.
Lactic acid is just a posh way of describing oxygen debts which is a cause of fatigue.
-
but you could run a mile and not be fatigued? and someone else could run a mile and be f*cked, non-fatigued wouldnt be so because none of the list has taken place... (not likely!)
so its not a specific activity causing it, its the one or more things on the list that are causing fatigue. no?
-
In order to suffer "catastrophe" fatigue, you have to use up various metabolites and liquids. The root cause of your fatigue is the activity that has caused you to do this.
However, according to the "Central Governor Theory", fatigue is not generally caused by these cited items. It's caused by the brain reacting to the feedback mechanisms within your body, causing you to reduce the amount of activity to avoid this catastrophic situation.
As a result, true exercise related fatigue is in fact a result directly of the exercise and the way your brain deals with it and not the list. There are a number of studies that reflect this. More importantly, sprint finishes wouldn't be possible in endurance events if catastrophic fatigue had really set in...

No i wouldnt disagree with that at all, but thats very complex and a psychological side to things. I am just saying having done school work, which college is very similar i owuld have thuoght, those 7 are the main ones that get you the marks and that will be recognised by the exam boards and markers.
You do bring a good point to the table though i must say!
