Heart Rate Calculations:



1. Meg is an 19 year old sophomore at CSU. She weighs 130 lbs and walks to school every day on the completely flat College Avenue. She walks at 3.5 mph and it takes her 12 minutes to get to campus.



a. Calculate how many calories she would burn in one day walking to and from campus.



2. Mathew is a 62 year old who refuses to use the heart rate monitors on the exercise machines, swearing they are never correct. His resting heart rate is 70 bpm. You tell him that he can take his own heart rate manually and does not need to rely on the machines.



a. Describe (using anatomical terminology) how you would tell him to take his heart rate.


b. What is his age predicted max heart rate?


c. Calculate his HRR for his “light” training days (40-55%)


d. For HRR, list the 6 second count as well as the RPE for his light training days.



3. Eric is a 64 year old moderate-risk client who weighs 180 lbs. He recently joined Adult Fitness and wants to walk on the treadmill at 4.2 mph at a 4% grade.



a. What is his estimate oxygen consumption (VO2) and METs during this workout?


b. How many total kcals would he expend if he were to walk at this speed and grade for 60 minutes?


MET Equations



4. Bryan recently had hip surgery and has been biking for ~ 15 minutes, every other day. His maximal aerobic power (VO2) is 46 mL/kg/min. You prescribe Doug to work at 65% of his VO2Reserve. Doug weighs 200 pounds.



a. Calculate his work rate.


b. How many total kcals would Doug burn if he biked for 30 minutes 4 times a week?



5. Mary is a 28 year women who is 10 weeks into her pregnancy. Her doctor wants her to be regularly active, and she comes to you for help. Which method (HR max, HRR, RPE or talk test) would you recommend for her and why?
