What are the proposed mechanisms for peripheral fatigue? (5)
Give this one a try later!
decrease in neurotransmitter release, decrease in receptor activity, change
in muscle membrane potential SR Ca 2+ leak channel, decrease in Ca 2+
release, decrease in Ca 2+-troponin interaction
What is Fast-twitch oxidative-glycolytic fibers (Type IIa) fatigue resistance and what
happens to its capacity to resist fatigue?
Give this one a try later!
Moderately to high fatigue-resistant & capacity to resist fatigue increases
with endurance training
,Which response might not be able to elicit a response?
Give this one a try later!
the 2nd stimulus
What is the following process referred to as: glucose is converted into pyruvate and
then enters into tricarboxylic acid cycle (TCA) to produce ATP with adequate oxygen
supply?
Give this one a try later!
oxidative-glycolytic
Normally, where does the pyruvic acid ender and what does it do there?
Give this one a try later!
it enters into the mitochondria to produce more ATP if oxygen is avalible
What is the result when the skeletal muscle fibre is stimulated at a rate of 20-30 times
per second?
Give this one a try later!
, the result is a sustained but wavering contraction (phenomenon known as
unfused or incomplete tetanus)
What does myoglobin have the ability to do?
Give this one a try later!
to bind to oxygen
How is ATP produced by anaerobic cellular respiration?
Give this one a try later!
mainly from blood, but also from muscle "bank"
What is neural connection failure or depletion of neurotransmitter usually related to?
Give this one a try later!
neuromuscular diseases rather than exercise
What is the first source of energy that the beginning of the muscle contraction?
Give this one a try later!
