Lesson 11 - Fitness Assessments | Physiological Assessment

Question 1

Measuring VO max in a laboratory involves the collection and analysis of _______________
during maximal exercise.

Answer 1

Exhaled air

Why?

VO max, an excellent measure of cardiorespiratory efficiency, is an estimation of the body’s
ability to use oxygen for energy, and is closely related to the functional capacity of the heart.
Measuring VO max in a laboratory involves the collection and analysis of exhaled air during
maximal exercise.

Question 2

A personal trainer can accurately estimate VO max from a client’s heart-rate response to
exercise.

Answer 2

TRUE

Why?

Research demonstrates that as workload increases, so do heart rate and oxygen uptake. In fact,
heart rate and oxygen uptake exhibit a fairly linear relationship to workload. This relationship
allows the personal trainer to accurately estimate VO max from the heart-rate response to
exercise with fairly good accuracy.

Question 3

If an activity requires a functional capacity of 6 METs, what is the total oxygen consumption of
someone performing that activity?

Answer 3

21 mL/kg/min

Why?

1 MET is equal to 3.5 mL/kg/min, so 6 METs = 6 x 3.5 mL/kg/min = 21 mL/kg/min
