1. How much work (in kgm) is accomplished when a 4 kg weight is lifted through a distance of 2 meters? (1 point)

2. If you lift a 3 kg weight a distance of 1 meters, 120 times in 3 minutes, what is the work rate (power) in kgm/min? (1 point)

3. What is the work rate (in kpm.min-1 and Watts) for a person cycling on a Monark leg cycle ergometer at 70 rpm and 2.5 kp resistance? (1 point)

3a) Work rate in kgm.min:

3b) Work rate in Watts:

4. What is the workrate at zero (0) kp resistance and 90 rpm? (1 point)

5. At a power output of 500 kcal/hr, how much energy (kcal) is expended in 30 minutes? (1 point)

6. 8 METs is equivalent to how many ml/kg/min of oxygen uptake? (1 point)

7. A person is exercising at an absolute VO2 of 0.92 L/min and they weigh 125 lbs. What is their relative VO2? (1 point)

8. How many total kcal would a person expend if they cycled at intensity of 32 ml/kg/min for 30 minutes? Their body weight is 76 kg. (2 point)

9. Using the MET method, what would be the energy expenditure in kcal/min of someone exercising at 4 METs and weighing 185 lbs? (1 point)

10. How much total energy (kcal) would some expend who is engaged in masonry work at a moderate effort for 4 hours (Physical Activity Compendium: code 11480)? They weigh 77 kg. Use the VO2 method to calculate the total energy expenditure, not the MET method. (1 point)

11. A 65-year-old woman has a VO2max of 26 ml/kg/min on the treadmill. What percentile ranking would apply to her? (1 point)

12. Graph the following data points as a scatterplot with a line of best fit using a computer graphics program such as EXCEL. Label the axes properly including the units in parentheses. Insert a linear trendline (In Excel: go to Design => Add Chart Element => Trendline => linear). Copy-paste the graph onto this document making sure all the features of the graph are retained. (2 points)

Velocity (m/min) Oxygen Consumption (ml/kg/min)

The graph you made for #12 allows you to estimate an oxygen consumption if the running speed is known or vice-versa. By drawing lines on the graph you have constructed, estimate a runner's running speed for each of the following VO2 amounts: (Provide the speed in m/min and show your work on the graph.) (2 points)

a) 51 ml/kg/min: ________________

b) 58 ml/kg/min: ________________

13. Using the graph, estimate oxygen consumption at the following speeds. (Hint: make sure all data is in m/min; Provide the oxygen consumption in ml/kg/min and show your work on the graph.) (2 points)

  1. 160 m/min: _______________

b) 250 m/min: _______________

13.Using the graph above, estimate the maximum oxygen consumption of a runner who runs three miles in 15:30 minutes? (Note: There are 1609 meters/mile. Convert miles to meters and divide by the amount of time it took to complete the run to yield m/min; Show your work on the graph.) (2 point)

Velocity:_______ m/min Maximal oxygen consumption: _________ ml/kg/min
