Mid-term Homework Name:____________________________ You must show all your work on back of page or separate sheet of paper. Part 1: Calculations (10pts) A 65-year old male has come to you to complete a submaximal exercise test. His resting heart rate was 81bpm and is 222 pounds and 71 inches. Calculate the following (SHOW YOUR WORK!): a. What is the subject's training heart rate range at 50-75% using the HRR method? b. What is the subject's weight in kilograms and height in meters? c. What is the subject's BMI? According to ACSM, what is his classification? d. After the test, you predict your subject's maximal workload to be 1215kg/m/min. What is his estimated VO2max (mL/kg/min)? e. What is the subject's fitness ranking based on his estimated VO2max (mL/kg/min)? Part 2: Metabolic Calculations Given the information below, complete the table including oxygen consumption and METs. Remember to check your units. Show your work on an attached worksheet.
