Question

1. What are the minimum and maximum resting heart rates for an individual to be cleared for participation in an exercise test? [2 marks]
2. Compared to rest, explain why an exercise heart rate pulse is easier to palpate at the radial artery? [2 marks]
3. What is the cut-off relative contraindication for exercise testing value for resting blood pressure? Include both systolic and diastolic cut-off values. [2 marks
4. Explain the normal change in blood pressure between rest, exercise and post-exercise recovery. [3 marks]
5. When measuring heart-rate it is sometimes advisable to start counting from zero and other times from one. Explain why this is necessary and under which circumstances each applies.
6. What are the terms given to resting heart rate greater than 100 bpm and less than 60 bpm?

Answer 1

●Exercise is a form of activity which first increases the heart rate.The normal heart rate is considered to be 60 to 100 beats/minute.For a person to participate in exercise testing the minimum testing heart rate should be not be less than 60 bpm and the maximum heart rate should not be more than 100 bpm.

●When a person exercise it increases the cardiac activity like it's pulse,blood pressure,volume,etc.,. An increase in systolic blood pressure increases .This pressure ways can simultaneously move the arterial walls making them more palpable.This palpable artery is more easily felt in the radial artery.

●The cut off relative contraindication for exercise testing value for resting blood pressure are systolic 140mmHg and diastolic pressure of 90mmHg

● The normal changes in the blood pressure are

Rest:The normal ranges from 120/80mmHg

Exercise:During exercise the systolic heart pressure can be elevated into 20mmHg and.In an Exercise test the blood pressure is considered normal till 160 to 200mmHg.In a healthy individual exercise doesn't increases the diastolic pressure ,if it happens a medical help to be seeked.

Post exercise:The blood pressure after exercises comes to the nearby value of resting blood pressure within one minute.Usually the systolic blood pressure reaches to its normal level in five minutes.If not a medical help will be needed.
