Answer: The purpose of pre-screening before the conduction of cardiovascular fitness testing is to identify individuals who may be at elevated risk for exercise-related sudden cardiac death and/or acute myocardial infarction. Pre-screening can also help determine the appropriate level and intensity of exercise for the individual, based on their current physical activity, medical history, signs or symptoms, and medication use. Pre-screening can reduce the potential harm and liability associated with exercise testing and prescription and promote the safety and effectiveness of physical activity interventions.
