KIN 375 Exam 2 2025/2026 Exam
Questions with 100% Correct Answers |
Latest Update
Work - 🧠 ANSWER ✔✔force x distance
Power - 🧠 ANSWER ✔✔(force x distance) / time
Ergometry - 🧠 ANSWER ✔✔- measurement of work on a device
- Erg = work
When is quantifiable work performed? - 🧠 ANSWER ✔✔- when walking or
running up or down a slope
Direct Calorimetry - 🧠 ANSWER ✔✔- measurement of heat production as
an indication of metabolism
- food + O2 --> ATP + heat
Indirect Calorimetry - 🧠 ANSWER ✔✔- O2 consumed
,- measures O2 used as an estimate of metabolic rate
- food + O2 --> heat + CO2 + H2O
How many kcals are in 1L of O2? - 🧠 ANSWER ✔✔5 kcals
Open-circuit Spirometry - 🧠 ANSWER ✔✔- Measures the amount of O2
used from the air (VO2)
- VO2 = vol. O2 inspired - vol. O2 expired
VO2 (L•min) vs. VO2 (ml•kg-1•min-1) - 🧠 ANSWER ✔✔VO2 (L•min) --> an
absolute amount of O2 used in L/min
VO2 (ml•kg-1•min-1) --> amount adjusted to body weight (relative to
individual)
How much O2 do we use at rest? - 🧠 ANSWER ✔✔~ .25 L/min-1 --> varies
based on body composition, & their metabolism (.20-.27)
What is resting metabolism? - 🧠 ANSWER ✔✔1 Met = 1 metabolic
equivalent
What is normal resting value? - 🧠 ANSWER ✔✔VO2 = 3.5 ml•kg-1•min-1
To convert L•min-1 to kcal•min-1 - 🧠 ANSWER ✔✔multiply by 5.0 kcals
, To convert L•min-1 to (ml•kg-1•min-1) - 🧠 ANSWER ✔✔multiply by 1000
anddivide by body weight in kilograms
To convert ml•kg-1•min-1 to METs or kcal•kg-1•hr-1 - 🧠 ANSWER ✔✔divide
by 3.5 ml•kg-1•min-1
What is the relationship between O2 requirement and speed? - 🧠 ANSWER
✔✔O2 usage ↑ in a + linear relationship as speed ↑ (m•min-1)
T/F: Walking demonstrates twice the slope as running? - 🧠 ANSWER
✔✔False
- walking: VO2 ml•kg-1•min-1 = (.1 x m/min) + 3.5
- running: VO2 ml•kg-1•min-1 = (.2 x m/min) + 3.5
Net Efficiency - 🧠 ANSWER ✔✔ratio of work output divided by energy
expended above rest
- % net efficiency = (work output/ energy expended above rest) x 100
What is the relationship between efficiency (energy expenditure) and work
rate? - 🧠 ANSWER ✔✔+curvilinear relationship
- efficiency decreases w/ increased work rate
