Question

6 & 27 Case Study: Please use the following information to answer questions 2 Here are the results of Mr. Barnes' GXT which was conducted physician present and no ECG monitoring. Mr. Barnes is 40 years old and has no major risk factors in your testing facilities without a 144/92 152/100 164/106 172/116 188/124 10 0-2 2-4 4-6 6-8 8-10 300 kg-m/m 450 kg-m/m 600 kg-m/nm 750 kg-m/m 900 kg-m/m 104 118 129 136 147 12 14 17 17. After reviewing the graded exercise test data, you conclude that: the test should have been terminated earlier because of excessive D8P response to exercise the test should have been terminated earlier because of excessive SBP response to exercise the test should have been terminated earlier because the RPE increased by too large an increment from min 6-8 to min 8-10 everything proceeded normally for Mr. Barnes a. b. c. d. 18. The heart rate response during the test is/has: a. b. c. d. relatively normal demonstrated excessive increases for each workload demonstrated a blunted increase for each workload reached maximum levels for Mr. Barnes 19. Generally, what is often the limiting factor during a maximal exercise test on a cycle ergometer? a. b. c. d. heart rate increases too quickly. DBP goes above 100 mmHg leg fatigue RPE reaches 19-20 20. What is quantified by the RPE scale? a. b. c. d. degree of difficulty breathing during exercise degree of chest pain during exercise degree of light-headedness during exercise subjective feeling of physical effort during exercise 21. How would holding onto the handrail likely affect a submaximal treadmill test? a. HR increases, VO;max would be overestimated b. HR decreases, VO;max would be overestimated c. HR increases, VO2max would be underestimated d. HR decreases, VO max would be underestimated 22. Which of the following does NOT typically change as a result of regular exercise training? a. Resting heart rate b. Maximal heart rate c. Heart rate response to a standard submaximal workload d. Anticipatory heart rate

Answer 1

17. After reviewing the graded exercise test :-

Option B) the test should have been terminated earlier because of excessive SBP response to exercise . Because the systolic blood pressure has crossed the maximum limits.

18. The heart rate response during the test is :-

A) relatively normal ,because according to the GXT his maximum predicted normal heart rate should be 220 - age ( for men ) .

19. The limiting factor during a maximal exercise test on a cycle ergometer is :-

- RPE reaches 19 to 20 due to hyperventilation

20. RPE scale is a frequently used quantitative measure of perceived exertion during physical activity .

The correct option is D) - subjective feeling of physical effort during exercise .
