|
determinants of VO2 max and what VO2 max is |
sex, genetics, mode of testing, age -max amt oxygen consumed despite increases in exercise intensity |
|
|
2 goals of aerobic training |
develop capacity of central circulation improve aerobic capacity of muscle |
|
|
limiting factors of VO2 max |
ventilation-respiration muscle metabolism central blood flow peripheral blood flow |
|
|
adaptations to aerobic training that increase O2 delivery to muscle
|
increased total blood volume
increased EDV increase EF increased SV increased CO |
|
|
a-v O2 difference
|
difference in O2 concentration of arterial and venous ends of capillary -- becomes larger during exercise
|
|
|
systolic blood pressure and exercise
|
systolic bp increases proportionally to exercise intensity (diastolic does not change)
|
|
|
pulse pressure =
|
SBP - DBP
|
|
|
Heart rate response to exercise
|
increase heart rate as oxygen uptake increases
-trained athlete: lower heart rate at higher oxygen uptakes than sedentary people |
|
|
stroke volume response to exercise |
increased stroke volume as oxygen uptake increases -largest stroke volume for trained athlete |
|
|
relationship of CO to O2 uptake |
steady increase of CO as oxygen uptake increases- largest cardiac output achieved by athlete
