Question

Case Study #4-CVD Bob is a 36 year old construction worker. He is mildly overweight (BMI-27), has hypertension, a family history of heart disease, no structured exercise and he is presently trying to quit smoking. One month ago, he complained of chest pain at work, and was rushed to hospital. A coronary angiogram confirmed that he had two (2) blocked arteries. Physicians tried to do angioplasty to open his clogged arteries but the procedure did not work. Subsequently, as a preventive measure, Bob had open heart surgery. His recovery in the hospital was excellent. His follow-up Bruce protocol test results (performed at rehab facility) are below Stage Stage Speed Grade Heart Blood (96) | Rate | pressure 120/80 Time Previous exercise history/diet history: never exercised before. Only reason he is exercising is because his wife and doctor have told him he needs to. Eats fast food for lunch every day. Only healthy meal is dinner Summary of Client Interview: thinks he gets enough exercise at work. "Hey I work hard all day, isn't that enough?" "When I'm I going to possibly find the time to exercise?" Medications: anti-coagulant-Coumadin. No arrhythmias noted during test 60 80 86 102 120 125/76 136 140 146 140/80 150 152 160 156/82 170 176 TEMINATION Standing 1.00 2.00 3.00 4.00 2.5 5.00 6.00 7.00 8.00 9.00 10.00 4.2 10.30 1.7 10 Answer the following questions. You may work with your group 1. Based on his test results, what is Bob's VO2 max? Calculate MET value (hint: Table 2.4) 2. Were his test responses considered normal? (hint: what should happen to HR & BP during 12 exercise?) Using the FITT principle, recommend a cardiovascular exercise program for Bob What SMART goals would you set for Bob to keep him motivated? What diet may his physician have recommended that you may be able to help him with? 3.4 14 3. 4. 5. IV 16

I only need help with questions 1 and 2, if you could please also explain why. thank you! (again I only need help with questions 1 and 2)

Answer 1

1.VO2 max is the number that ecpress just how much oxygen you consume when exercising your hardest.

The formula used to calculate VO2 max is

VO2 max= 15×(MHR/RHR)

MHR( Maximum Heart Rate) =220- his age, ie 220-36=184

RHR(Resting Heart Rate) = 60

Then VO2 max = 15×184÷60 = 46.001mL/Kg/Min

MET are used to estimate the energy expenditure for many common physical activities. One MET is an individual resting metabolic rate (RMR) and is approximately 3.5 Milliliters of oxygen consumed per kilogram body weight per minute.

MET = VO2 max/VO2 at rest

We already found VO2 max is 46.001 and VO2 at rest is set by convention at 3.5 ml of oxygen per kilograms per minute.

MET=46.001/3.5= 13.14

VO2 max is 46.001 and is in the category " Good "for age group 36-45.

2.During each stage of exercise, HR is keep on increasing. It is considered normal and may extend upto 175 bpm.

Irrespective of apparent normal BP at resting phase, some individual may elevate to excess level during exercise. ie systolic BP upto 220 mm Hg and diastolic BP upto 110 mm Hg in men.
