1) You have a job interview downtown at 9:00 AM sharp. The interview is on the 12th floor. You arrive in the lobby at 8:55 only to find out the elevator is out of order. You run up the 180 steps in 1 minute and 47 seconds. If the steps are 8 inches high, what was your VO2 when you ran up to your job interview?
2) Your client has been told that she should begin her exercise program at 50% of her VO2reserve. She wants to walk on the treadmill with a 3% grade. How fast should she walk? Her VO2max is 37.8 ml . kg-1 . min-1 and she weighs 136 lbs.
3) For the same woman in Question #2 with the same exercise prescription, what would be the power output required on the arm ergometer?
4) Your client is 41 years old with a resting HR of 62 bpm. What would his HR be at 60% of HRreserve?
5) When administering the bench step test to estimate VO2max , the bench height is 16.25 inches. The stepping rate is 22 steps per minute for women. That is, the metronome is set to 88 beats/clicks per minute and the person steps up on the bench with one foot on the first beat/click, up with the other foot on the second beat/click, down with the first foot on the third beat/click, and down with the other foot on the fourth beat/click.
What is the VO2 for a woman performing the test?
Below are the results of lactate threshold test done on a 26 year old woman who is a distance runner.
VO2max = 58.6 ml/kg/min
Running speed at VO2max = 11.5 mph
HRmax = 189 bpm
At LT1
VO2 = 39.26 ml/kg/min
Running speed = 7.0 mph
HR = 125 bpm
At LT2
VO2 = 49.8 ml/kg/min
Running speed = 10.0 mph
HR = 175 bpm
Based on these results,
6) Below what HR and running speed would be considered low intensity for this distance runner?
7) What range of HRs and speeds would be considered low to moderate intensity for her?
8) What range of HRs and speeds would be considered moderate to high intensity for her?
9) Above what HR and running speed would be considered high intensity for this woman?
10) Based on these results, is she at optimal fitness level? Explain your answer.
