HKIN 191 Final Exam Questions and
Answers 100% Pass
Body Volume - ✔✔the amount of space that a body takes up, can be measured through
hydrodensitometry or displacement.
Body Density - ✔✔The weight of molecules present in a certain volume.
D= Mass (kg)/Volume (m^3)
Archimedes' Principle - ✔✔The buoyant force on an object is equal to the weight of the
fluid displaced by the object. An object heavier than the water it displaces will sink,
lighter will float. Can be used to calculate body fat %.
Underwater weighing (hydrostatic) - ✔✔Measure of body composition by expelling all
air from lungs and then being weighed. Extremely accurate.
Tare weight - ✔✔Also called unladen weight, is the weight of an empty container.
Body Mass Index - ✔✔weight (kg) / height^2 (m^2) categories on p. 803
Waist Girth - ✔✔The measurement of waist at navel while standing relaxed.
Waist-to-Hip Ratio (WHR) - ✔✔waist girth / hip girth

, Energy Balance - ✔✔The relationship between intake of food and output of work.
Positive when body stores extra food as energy and Negative when body draws on
stored fats to provide energy.
Weight change = total energy intake - total energy expenditure.
Weight gain: Energy intake - CHO, Fat, Protein
Weight Loss: Energy Output - Thermic effect of food, physical activity, resting
metabolism.
Individual Needs - ✔✔Specific needs for their sport, and their responses
Specificity vs Generality - ✔✔Specificity will be specific to that person's sport, training,
system, and testing. Generality is how in general, a person with a high VO2max in one
area will probably have a high VO2max in another area.
Intensity/Duration - ✔✔Depends on how hard and how long someone is putting effort
in to a specific test.
Calorie - ✔✔Amount of energy needed to raise temperature 1 gram of water 1 degree C
Redox - ✔✔The chemical reaction in which the oxidizing agent is reduced and the
reducing agent is oxidized.
Oxidation - ✔✔Reactions that transfer oxygen, hydrogen, or electrons. A loss of
electrons. LEO
