Why is BMI measured in physical education classes?

• A. To measure flexibility
• B. To determine cardiovascular endurance
• C. To screen health by weight-to-height ratio
• D. To assess athletic potential

Answer: (C)

BMI in physical education is used to screen health by weight relative to height. It provides a quick snapshot of whether a student’s body weight may be outside a healthy range for their height, signaling when follow-up with a health professional might be helpful. It isn’t a measure of flexibility, cardiovascular endurance, or athletic potential—those aspects come from other fitness tests and performance measures. Remember, BMI doesn’t distinguish fat from muscle or capture how fat is distributed, so it’s a starting point for screening rather than a definitive health assessment.
