acute responses Flashcards
(17 cards)
what are the acute cardiovascular responses
Heart rate
stroke volume
cardiac output
redistribution of blood flow
venus return
systolic blood pressure
what are the acute muscular responses
motor unit recruitment
firing rate
a-Vo2 diff
depletion of fuels and increased enzyme activity
muscle temperature
production of metabolic by products
what are the acute respiratory responses
respiratory rate
tidal volume
ventilation
pulmonary diffusion
what is pulmonary diffusion
exchange of gasses between the lungs and bloodstream (O2 in c02 out)
explain increased motor unit recruitment
more motor units recruited the more force produced
what is a motor unit
a muscle fiber and its attached motor neuron
what is arteriovenous oxygen difference
difference in oxygen concentration between the arterioles and the venules.
An indirect measure of how much oxygen muscles are using
what is the ATP-CP fatiguing factor and most appropriate recovery method
depletion of CP stores
passive recovery
what is the anaerobic glycolysis fatiguing factor and most appropriate recovery method
accumulation of H+ ions
active recovery
what are the three aerobic fatiguing factor and most appropriate recovery method
accumulation of H+ions-active recovery
Depletion of glycogen-eat carbs
Thermoregulation-cool/warm body
what is passive recovery
when you stand/sit still, allows all available O2 to replenish CP
how long does the aerobic system use glycogen
90-120 mins before glycogen depletes within the body, then uses triglycerides
what are the affects of sweat
loss of blood plasma, blood becomes thicker, stroke volume decreases, HR increases, body works harder
how does water help recovery
restores blood plasma, optimizing blood flow
how do carbohydrates help recovery
uptake of glycogen is highest immediately after exercise, 30-60 mins after “window of opportunity”
why is protein consumption important
recover faster from heavy load or generate appropriate adaptions from training
what should you co-ingest
carbs and protein
carbs and water
