What is the typical resting heart rate reference range for a young adult?

• A. A 40-60
• B. B 60-100
• C. C 80-120
• D. D 100-140

Answer: (B)

Resting heart rate is the number of times the heart beats each minute when the body is at rest. For a healthy young adult, the typical reference range is about 60 to 100 beats per minute. This range accounts for normal daily variation due to fitness level, autonomic nervous system balance, and recent activities. Values below 60 can occur in people who are very well trained, since their hearts pump more efficiently; values above 100 at rest suggest tachycardia and can be due to factors like fever, dehydration, stress, caffeine or stimulant use, anemia, or thyroid issues. So, the 60–100 beats per minute range best represents a normal resting heart rate for a young adult.
