Regular training leads to what change in resting heart rate?

• A. Increased resting heart rate
• B. Decreased resting heart rate
• C. No change in resting heart rate
• D. Random fluctuations in resting heart rate

Answer: (B)

Regular aerobic training makes the heart more efficient at delivering blood. With consistent training, the heart becomes capable of pumping more blood with each beat (the stroke volume increases) because its walls adapt and become stronger, and the circulation becomes more efficient overall. Because the amount of blood the heart needs to move at rest doesn’t change, pushing a larger volume with each beat means the heart doesn’t have to beat as often to achieve the same total blood flow. In other words, resting cardiac output remains about the same, but resting heart rate drops. This lower resting heart rate is a common sign of improved cardiovascular fitness. So, the best description of what regular training does to resting heart rate is that it decreases it.
