What are common methods for measuring heart rate?

The reason that ECG, HR monitors, stethoscopes, and palpation are recognized as common methods for measuring heart rate is due to their direct and effective nature in establishing how many times the heart beats in a minute.

An electrocardiogram (ECG) provides a real-time graphical representation of heart activity, allowing for precise measurement of heart rate, as well as insights into heart rhythm and function. Heart rate monitors often use electrodes or optical sensors integrated into wearable technology, offering convenience and continuous monitoring during various activities. Stethoscopes allow clinicians to listen to heartbeats directly, thus enabling them to manually count heart rate, while palpation involves physically feeling the pulse at key areas like the wrist or neck to determine heartbeats per minute.

Other options involve different physiological measurements unrelated to heart rate specifically. For instance, assessing resting metabolic rate and strength or conducting flexibility tests and muscle endurance tests focus on other aspects of physical fitness. Skinfold measurements and BMI assessment relate to body composition rather than heart rate, making them irrelevant when considering methods specifically for measuring heart rate.
