Exercise Physiology Flashcards
Exercise and effect on maxCO vs resting CO
Max CO will increase with aerobic training, but not resting CO
What can be used to estimate the MVO2
Rate pressure product (RPP)
VO2 corresponds to which muscles?
Peripheral skeletal muscles
Relationship between anginal threshold, MVO2, and VO2
MVO2 and VO2 increase in a linear fashion until it reaches anginal threshold, which is the point at which MVO2 exceeds ability of coronary circulation to meet demand
Effect of exercise on SV
Exercise increases resting SV
Force of contraction in response to increase stretch
frank starling relationship
Effect of exercise on HR
Exercise decreases HR at rest, but does not change max HR
Effect of HR on SV and EDV
Faster HR = decrease EDV = decrease SV
MET
Metabolic equivalent. Ratio of working metabolic rate to resting metabolic rate.
Point where increase in work does not increase VO2
VO2 max
Relation between SV and sitting vs standing
SV decreases when standing up.
SV is max when lying down.
Represents oxygen consumption of the whole body
VO2
Units of VO2max
mL O2/kg/min
Effect of exercise on VO2 vs VO2max
Increases VO2max but not VO2.
