Question

what is heart rate ?​

Answer 1

Answer:

Heart rate is the speed of the heartbeat measured by the number of contractions of the heart per minute.

Answer 2

Answer:

• The number of times the heart beats within a certain time period, usually a minute.

• A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.
