Ex Phys: Test 2

Measuring heat production in the body in order to estimate energy expenditure is

Direct Calorimetry

At rest, the average person burns approximately

1.0 kcal/min

The rate of energy expenditure for an individual at rest measured approximate 4 hours after a light meal and after 30-60 minutes of resting quietly is the

Resting Metabolic Rate (RMR)

Lactate Threshold (LT) is usually expressed as the

 

%VO2 max at which it occurs

Which of the following VO2 max values would be more likely to be recorded in an elite male endurance athlete?

 

75 ml/kg/min

According to classical excess postexercise oxygen consumption (EPOC) theory, the fast portion of the curve represents

 

Rebuilding of phosphocreatine stores

Higher exercise intensities have lower O2 deficits than lower intensity work.

False

If all other variables are similar between two athletes, the one with the better running economy (economy of effort) is likely to do better in endurance events.

True

In which of the following situations, should RER not be used?

 

During an all-out sprint to exhaustion

Which of the following is NOT a potential cause of an increase in blood lactate values (i.e. reaching the lactate threshold (LT))?

low muscle glycogen
