Work tests to evaluate cardiorespiratory fitness

Dr. Imran Rafiq

Objectives 1.Identify the sequence of steps in the procedures

for evaluating cardio respiratory fitness (CRF). 2.Describe one maximal and one submaximal field test used to evaluate CRF. 3.Explain the rationale underlying the use of distance runs as estimates of CRF. 4.Identify the common measures taken during a graded exercise test (GXT). 5.Describe changes in the ECG that may take place during a GXT in subjects with ischemic heart disease.
