What is the normal resting heart rate range for adults?

• A. 60-100 beats per minute
• B. 50-70 beats per minute
• C. 70-90 beats per minute
• D. 40-60 beats per minute

Answer: (A)

Normal resting heart rate for adults is about 60 to 100 beats per minute. This range reflects heart activity when the body is at rest and the demand for oxygen and nutrients is low, so the autonomic nervous system can keep a steady pace. Fitness level influences this: well-trained athletes often have lower resting rates, sometimes in the upper 50s or even 40s, because their hearts pump more blood with each beat (greater stroke volume). Rates above 100 can occur with illness, stress, dehydration, caffeine, medications, or fever, and are considered tachycardia when persistent. Conversely, resting rates consistently below 60 aren’t always a problem—bradycardia can be normal in some healthy individuals, especially athletes, but it can indicate issues in others. If a resting heart rate is consistently outside this range or is accompanied by symptoms like dizziness or shortness of breath, seek medical advice.
