Question 10

VO₂ max can be estimated by completing a cycle ergometer test to exhaustion.Calculate the estimated VO₂ max from a graded cycle ergometer test given the following information: Subjects age = 40 years old

Highest work rate achieved on cycle = 1000 kpm
VO₂ (ml^. min^-1)= (1.8 ml^.kpm^-1 X kpm^.min^-1 )+ (7ml^.kg^-1.min^-1 X kg body weight)

A)1800
B)2304
C)1296
D)VO₂ max cannot be calculated from the above information

Question 11

The "double product" is___________________.

A)an estimate of cardiac work and oxygen demand
B)computed as the product of heart rate and systolic blood pressure.
C)a biomarker indicating that the subject has reached their maximal heart.
D)Both A and B are correct

Question 12

A sphygmomanometer may be used during a cycling exercise test to determine

A)arrhythmias.
B)conduction disturbances.
C)myocardial ischemia.
D)blood pressure.

Question 13

VO₂ max can be estimated by drawing a line through the heart rate values measured during a submaximal graded exercise test and extrapolating to the age-adjusted maximal heart rate.This VO₂ max estimate could be incorrect if:

A)the subjects true maximal heart rate was incorrectly estimated.
B)the subject held onto the treadmill railing during the test.
C)the measurement of treadmill speed and grade were inaccurate.
D)All of the above answers are correct
