UNIT: J/S

Question 7

___________ Any device that is used to measure work:

Ex:

• Bench step
• cycle
• arm
• Treadmill

Answer 7

Ergometer

Question 8

Bench: given 70kg person on 30 cm step @ 30steps/min for 15 min

Find work in KPM?

Answer 8

Bench: given 70kg person on 30 cm step @ 30steps/min for 15 min:

Work= 70kp X 0.3 m/step X 30steps/min X 15 min

70 kp

0.3M

30 steps

15min

=9450 kpm

Question 9

Treadmill: Given 70kg person on a 10% grade @ 100m/min for 15min

Find work in KPM:

Answer 9

Treadmill: Given 70kg person on a 10% grade @ 100m/min for 15min

70kp

0.1

100m/min

15m

10500 KPM

Question 10

Cycle: given 2 kp resistance against flywheel @ 50 rpm (rev/min) for 15 min, flywheel travels 6 m/rev

Find work in KPM

Answer 10

Work = 2 kp X 6 m/rev X 50 rev/min X 15 min = 9000 kpm

Question 11

How do you convert kpm to J or convert force to N before multiplying.

Answer 11

Once you have work in J, divide by time in seconds to get power (work rate) in Watts. Or, you can calculate work rate initially without calculating work first by doing above but not multiplying by time. This will give you work rate in kpm/min. Then, can convert kpm/min to Watts

Question 12

Bench: given 70 kg person on 30 cm step @ 30 steps/min for 15 min

Find in KPM/Min

Answer 12

Bench: given 70 kg person on 30 cm step @ 30 steps/min for 15 min

Work rate= 70 kp X 0.3 m/step X 30 steps/min = 630 kpm/min

Question 13

GIVEN just be understand what they mean

1Kg=1Kp=9.81J

1w=6.12KPM/min

1 j= 1 N.M

1kpm/min= 0.263 W

Answer 13

GIVEN just be understand what they mean

1Kg=1Kp=9.81J

1w=6.12KPM/min

1 j= 1 N.M

1kpm/min= 0.263 W

Question 14

What does % Grade Mean?

Answer 14

Amount of vertical rise per 100 units of belt travel.

ex. 10% grade means 10m vertal rise for 100m of belt travel.

*So for every 1unit of vertical rise 10 units of horizontal movement.

Question 15

What is a Kcal?

Answer 15

1 kcal= Amount of heat required to raise the temperature of 1 kg of water by 1 Degree Celsius

1kcal=4186j

Question 16

What are the differences between

kcal, Calorie, calorie

Answer 16

1kcal=1000calories

Question 17

________ caloriemtry is the measurement of heath production as an indirect metabolic rate.

Answer 17

Direct Calorimetry

Question 18

________ Calorimetry is the measurement of oxygen consumptionas an estimate of resting metabolic rate.

Answer 18

Indirect calorimetry

Question 19

_____=volume of o2 inspired (-) volume of o2 inspired.

Answer 19

VO2

Question 20

When converting ablsolute Vo₂ (L/min) to Relative Vo_{2 (ml/kg/min)} you would do what?

Answer 20

Take the Absolute Vo₂ and multiply by 1000 then ÷ by the body weight/mass.

Question 21

just know that average Kcal consumption for 1L/o_{<span>2 </span>}

is ______

Answer 21

5kcals/ L.o₂^-1

Question 22

1 met =_______

In relative VO₂

Answer 22

3.5 ml/kg/min
