How many risk stratification categories are defined by ACSM?

The American College of Sports Medicine (ACSM) defines three risk stratification categories in the context of exercise and physical activity assessments. These categories are based on an individual's health history, specifically regarding cardiovascular diseases, metabolic conditions, and their overall health status, which helps in determining the level of supervision or intervention needed during exercise programs.

These three categories are:

1. Low Risk: Individuals with no known cardiovascular, metabolic, or renal disease and no more than one risk factor.
2. Moderate Risk: Individuals with no known cardiovascular, metabolic, or renal disease but with two or more risk factors.
3. High Risk: Individuals with one or more signs or symptoms of cardiovascular, metabolic, or renal disease, or those with established disease.

These classifications are important for tailoring exercise interventions to match individuals' health and safety needs, ensuring appropriate monitoring and guidance during physical activity. The existence of three categories provides a structured framework for health professionals to assess risks and implement suitable exercise prescriptions.
