Week 3

Question 1

Define calorimetry

Answer 1

Calorimetry is the study of measuring heat transfer during physical or chemical processes, such as reactions, phase changes, or heat capacity determinations. This is done using a calorimeter, an insulated device that minimizes heat exchange with the environment. There are two primary types: direct calorimetry, and indirect calorimetry. Calorimetry is essential in fields like thermodynamics, chemistry, and biology to analyze and quantify energy transformations.

Answer 14

Question 15

Explain oxygen deficit in trained vs untrained individuals

Answer 15

Question 16

Explain

Answer 16

Maximal oxygen uptake (VO2 max):

3 minutes per grade

Grades increase intensity

VO2 max plateaus at higher grades

Question 17

Explain VO2 max

Answer 18

Question 19

Explain

Answer 19

Question 20

Explain recovery oxygen consumption

Answer 20

Question 21

What are the factors that contribute to EPOC following exhaustive exercise?

Answer 21

Question 22

Explain BMR and RMR

Answer 22

Question 23

Does increased fat free mass affect RMR?

Answer 23

yes, higher levels of fat free mass = higher RMR

Question 24

Explain metabolism and the factors that affect total daily energy expenditure (TDEE)

Answer 24

Question 25

How does climate affect RMR?

Answer 25

Question 26

What is diet induced thermogenesis (DIT) and thermic effect of food (TEF)?

Answer 26

Question 27

Describe the calorigenic effect of food and exercise

Answer 27

Question 28

What are the physical effects on TDEE?

Answer 28

Question 29

Explain metabolic equivalent of a task (MET)

Answer 29

Question 30

What are the five level classifications of physical activity based on energy expenditure?

Answer 30

Question 31

What are the average daily rates of energy expenditure?

Answer 31

Question 32

Explain

Answer 32

Question 33

Explain energy expenditure during walking and the factors that affect it

Answer 33

Question 34

Explain

Answer 34

Question 35

Explain energy expenditure during running

Answer 35

• Energy requirement for running a given distance at steady-rate is about the same regardless of running speed
• Energy requirement to complete each mile remains fairly constant regardless of running speed
• Example: a person who weighs 62 kg requires about 2600 net kcal to run a 26.2-mile marathon regardless of whether the run takes just over 2 h, 3 h, 4 h, or more
