Michelle is a 36-year old nonsmoker who weighs 108lb (49kg) and is 5’1” (155 cm) tall. She works as an office manager and would like to begin an exercise program to improve her fitness. Two months ago, she started walking 1-2 times per week for 20-30 minutes. Her father had a heart attack at the age of 75 and her mother has osteoporosis, but is otherwise in good health. She recently completed a fitness evaluation, which revealed the following: Resting blood pressure: 110/70 mmHG Resting heart rate: 68 bpm. Lipid profile: Total Cholesterol: 182 mg/dl; LDL of 118 mg/dl; HDL of 52 mg/dl Fasting glucose: 93 mg/dl A YMCA submaximal test was performed. The following are the results of her test: Stage Work rate (kgm/min) HR Blood Pressure 1 150 93 125/72 2 450 130 140/70 3 600 155 152/69 Questions: 1. Calculate her BMI (1 pt): 2. List her cardiovascular risk factors. What her classification of risk? Does she require medical clearance prior to starting an exercise program? Does she need a physician present for exercise testing (be specific regarding moderate and vigorous exercise and submaximal or maximal testing)? (2pts) 3. Calculate her VO2 max: a. Using the graphing method (3 pts) Image transcription text Name: Age: Weight: Predicted Max HR Date 1st Workload HR >110 2nd Workload HR >110 (Est) Max Workload (Est) Max 02 (L . min-1) (Est) Max 02 (mL . kg-1 . min-1) Test #1 Test #2 Test #3 Directions: HR HR 1. Plot the HR of the two 200 200 workloads versus the work (kg . m . min-1). 190 190 2. Determine the subject’s 180 18… Show more b. Multi-stage formula (use the last two stages for the formula- i.e. Stage 2 will be used for VO21 HR1 and Stage 3 will be used at VO22 and HR2). (3 pts) VO2max= VO22 + b(HRmax – HRs) b= (VO22 – VO21)/(HR2 -HR1) 4. Classify her fitness level (1 pt): 5. What exercise intensity would you prescribe? a. VO2 reserve method (choose a range- and be specific as to why you choose that range). (2 pts) b. Express the range in terms of METs (2 pts) c. HR reserve method (provide the range) (2 pts) d. What is her minimum intensity (threshold) for Michelle? (1 pt) 6. Design an exercise program for Michelle (complete the following table—show all work) (10 pts).
