Expectations for the exam?
akkxn:
Yeah just saw that in the 2004 exam. The assessors report had some half-assed explanation which didn't even make sense.
In relation to energy systems, I think finite capacity refers to the oxygen deficit created by the anaerobic systems, namely the ATP-PC system which has finite stores of PC therefore a finite capactiy?
However I'm still confused how it relates to the LA system. Anyone?
mtwtfss:
Hydrogen ions limit the function of the LA system.
studyhound:
yeah that sorta makes sense,
im just going to interpret finite capcity as the factor which limits the energy system from opperating,
ATP-PC : limited PC stores
LA : H+ ion accumulation
Aerobic : oxygen deficit / depletion of glycogen stores
correct me if im wrong :)
mtwtfss:
Um...Aerobic system is pretty much infinite..maybe? someone correct me on this?
Depletion of glycogen stores would be a fatiguing factor though, doesn't stop it from working.

Yeah aerobic energy system has an (reletively) infinite capacity. Apparentely we can walk for 50 hours non-stop using the fat stores in our body
Thanks for clearing up the finite capacity of the LA system
