Answer 4

MET

Question 5

if you want to (truly) measure caloric expenditure, you must obtain you _
- limited practical applications

Answer 5

O2 consumption

Question 6

_ do not account for:
- body mass/adiposity (composition)
- sex
- age
- efficiency of movement (economy)
- geographical location (altitude)
- environmental conditions (Ex: smoke)
- individual differences (fitness level)

Answer 6

MET estimates

Question 7

based on measuring an exerciser’s O2 uptake
- energy-releasing reactions depend on oxygen use

Answer 7

indirect calorimetry

Question 8

indirect calorimetry:
- assumed that oxygen consumed is related to the amount of heat produced in the body during _
- we will be measuring caloric expenditure using _ and _

Answer 8

• exercise
• O2 consumption, heart rate

Question 9

indirect calorimetry:
- if we know Vo2, we can calculate _
- an oxygen uptake of 1 L*min-1 is approximately _

Answer 9

• caloric expenditure
• 5 Kcal*L-1
