Before carrying out any tests, it is necessary that you confirm your ability to withstand the stress of the test you are about to undertake. Normally, you should take into account your:

• demographics

•  lifestyle

• known diseases

• risk signs and symptoms

• cardiac risk factors

• self analysis

If you are going through fomal screening you should obtain answers to these three questions:

1. Do you need a medical check-up and stress ECG before being tested or undertaking exercise?

2. Does a medical doctor need to be present during a maximal test?

3. Does a medical doctor need to be present during a submaximal test?
