What is the primary purpose of a health screening before a fitness assessment?

The primary purpose of a health screening before a fitness assessment is to identify any medical conditions or risks that may affect exercise safety. This step is crucial because it helps to ensure the well-being of the participant by uncovering any potential health issues that could pose a risk during physical activity. Issues such as cardiovascular disease, orthopedic concerns, or other health status indicators can be recognized through this screening. By understanding these factors, trainers and fitness professionals can modify exercise plans, provide specific guidance, or refer individuals to healthcare providers when necessary to prevent injuries and ensure safe participation in fitness activities.

The other options focus on aspects that, while important, do not directly address the primary safety concerns associated with initiating physical exercise. Creating a customized workout plan, determining fitness goals, and assessing motivation levels can all be informed by information gathered during the screening, but they do not serve the primary function of protecting the participant's health and safety during exercise.
