Practice Problems

 

1.      You want a client to exercise at 7 METs on a treadmill.  Your treadmill is broken and will only work at a 10 percent grade.  At what walking speed should you set the treadmill?

 

2.      Your client has a VO2max of 58 ml. kg-1. min-1.  You want him to exercise at 85 percent of his VO2max on a treadmill.  If the speed is set at 7 mph, what percent grade should be used?

 

3.      You want your 47 kg client to exercise at 10 METs on a Tunturi bike.  If she pedals at 50 rpm, what resistance setting is needed?

 

4.      You want your 100 kg client to exercise at 60% of his 4.5 L . min-1 capacity on a Monark bike.  If he pedals at 60 rpm, what resistance is needed?

 

5.      Your 53 kg client has a VO2max of  2.1 L . min-1 during arm exercise.  What workload in kgm . min-1 would place her at 60% of her capacity?

 

6.      If an individual reduces his or her dietary intake by 1750 kcal per week, how much weight  (in lb) would he or she lose in 6 months (26 weeks)?

 

7.      If an 18 year old female steps up and down on a 12-inch step at a rate of 20 steps (complete up and down cycles) per minute, what would her gross VO2 be

      (in ml. kg-1.min-1) ?

 

8.      You want your client to exercise at 15 ml. kg-1. min-1.  You plan to use a stepping rate of 24 steps per minute.  What step height in inches is needed?

 

9.      A 62 kg client walks on a treadmill at 3.2 mph and 12 percent grade.  What is the metabolic cost?

 

10.  Which of the following would provide a metabolic cost equal to 14.30  METs for a 62 kg client?

  1. Running on a treadmill at 6 mph and 18 percent grade
  2. Cycling at 1200 kgm . min-1
  3. Stepping at a rate of 50 steps per minute on a 12 inch platform
  4. Walking at 4 mph and 5 percent grade
