Acute Responses to exercise
Acute cardiovascular
responses
Increased cardiac output
(Q = SV x HR)
Increased heart rate
Increased stroke volume
(Plateaus at sub-max level)
Increased systolic blood pressure
(Diastolic remains the same)
Redistribution of blood flow
from organs to working muscles
Vasoconstriction to organs
Vasodilatation to working muscles
Increase in Arteriovenous oxygen difference
Increase in venous return
Muscle pump
Respiratory pump
venoconstriction
Acute respiratory responses
Increase in ventilation
(V = TV x RR)
Increase in tidal volume
(plateaus at sub-max level)
Increase in respiratory rate
Increase in Diffusion
Acute muscular responses
Increased blood flow
Increased number of muscular contractions
Increased muscular temperature
Increased enzyme activity
Increased muscle fire recruitment
Decreased fuel stores
Loss of ATP
Depletion of PC stores
(after about 10-15 seconds)
Depletion of muscle glycogen
(Long term)
Lactate inflection point
The last point where lactate removal equals lactate production
Occurs beyond 85% of max heart rate
Produces lactic acid
Lactate
Hydrogen ions
(Produces fatigue)
