Cardiovascular responses to exercise part 2 Flashcards
does upper or lower body exercise have lower SV and higher HR
upper body
what are the 3 reasons upper body exercise leads to lower SV and higher HR
increased sympathetic input
lower venous return
recruitment of more torso muscles
what 5 things are higher in upper body exercise than lower
HR SBP DBP TPR RPP
what 2 things are lower in upper body exercise
SV
VO2 max
what happens to Q with sustained static exercise?
increased due to increased HR
what happens to SV with low and high intensities
constant at low and decreases at high
responses to resistance exercise
increase in HR
no change in SV
small increase in Q
large increase in bp
females have higher __ and lower ___ than males at the same work load therefore higher ____
higher HR, lower SV, higher Q
why is it harder for females to maintain the same aerobic work load as males
smaller size and smaller heart
lower O2 carrying capacity
lower VO2 max
true or false: a 25 year old man will have a different max HR than a 25 year old woman
false
children compared to adults
higher HR, SBP, max HR
lower SV, VO2 max
Elderly compared to younger adults
lower: SV, Q, max HR, VO2 max
higher: HR, SBP and DBP
during high intensity static exercise stroke volume will?
decrease because decreased venous return due to intra-throaci pressure and increased LVESV due to high arterial pressure
anticipatory increase in HR is due to?
parasympathetic withdrawal (vagal tone) release of catecholamines
blood plasma is lost during prolonged exercise mainly because of?
sweating
