What is an exercise test?
The main purpose of exercise testing is to measure your body’s ability to produce energy or in other words your exercise capacity.
The test might include walking on a treadmill, cycling or stepping up and down on a step. It is used to assess what your ability is to perform the activity and to assess your endurance in doing the activity. From the testing you will get a maximum heart rate and a reading called a MET level. MET stands for metabolic equivalent. When you are resting sitting in a chair you use 1 MET. For weeding the garden you will use 2.5 METs. The test tells you what your Maximum MET capacity is at that time and you can be advised on what activities you have have sufficient exercise capacity.
Why do I need an exercise test?
While exercise testing takes a very short time it gives quite a lot of information. If you are very breathless the test will give a level where the breathlessness starts and assesses your hearts and oxygen capacity level response to it. It is also used to ensure the settings on the pacemaker are fully optimized for you. From the test an exercise regime can be prescribed specific to you.

At Heart 2 Heart we complete functional exercise testing with you before you commence our exercise classes.
