What are the normal ranges for adult resting heart rate?

• A. 50 to 80 beats per minute
• B. 60 to 100 beats per minute
• C. 70 to 110 beats per minute
• D. 80 to 120 beats per minute

Answer: (B)

The normal resting heart rate for adults is typically defined as 60 to 100 beats per minute. This range is considered standard for a healthy adult at rest, as it reflects an efficient cardiovascular system capable of maintaining adequate blood circulation while the body is in a state of minimal physical exertion.

The heart rate can be influenced by several factors including age, fitness level, medications, and overall health. Athletes, for instance, may demonstrate resting heart rates that fall below 60 beats per minute due to superior cardiovascular conditioning. However, for the general adult population, maintaining a resting heart rate within the range of 60 to 100 beats per minute is indicative of a normal heart function.

Heart rates below or above this range can signal potential health concerns and may warrant further evaluation. Therefore, recognizing this normal range is crucial for assessing cardiovascular health.
