ml/kg/min or L/min
|
|
|
what is VO2 max measured?
|
good measure of cardiorespiratory fitness, evaluation of endurance training programs, screen of people for various tasks, diagnosis/modification of training program descriptions
|
|
|
3 factors influencing VO2max
|
circulation, type of exercise, adaptation
|
|

|
manual method of measuring VO2 max?
|
expired gas is collected in meteorological balloons durign exercise and then analyzed

|
|
what is the automated method of measuring VO2max?
|
inspired gas is directed through a pneumotachograph or a turbine devie which measures air flow rate, expired gas is routed to a mixing box

|
what can VO2 max aid in determining measures of physiological stress responses to exercise?
|
linear relation between work load and energy cost, linear HR response to exercise, recovery of cardio respiratory system to exercise
|
|
|
what is a threat to validity of the 20m shuttle test?

21 year old sedentary female, 21 year old female having trained for a year
|
|
|
at what speed does the subject run at to measure metabolic responses to prolonged exercise?
|
115m/min for 60, then for 120min in trained female
|
|
|
what metabolic responses are measured to prolonged exercise?
|
pulmonary - VO2, RER
blood - glucose, FFA, FFA uptake, glycerol, catecholamines Sarcoplasmic - glycogen and mitochondrial volumes Blood glucose regulation - muscle glucose uptake, liver glycogen, liver output |
