If you're asking what that number is called, it's "Heart rate" or sometimes "pulse rate" or "pulse" (technically these are different, though in practice they're usually the same number).
If you're asking what a device to measure that would be, the general term is "heart rate monitor."
Pulse
Your pulse measures the action of the heart.
Pulse Rate is the number of times your heart beats in a minute. Breathing Rate (Respiratory Rate) is the number of times you breathe in one minute.
The number of times your heart beats in a minute, the heart rate.
Number of beats per minute the heart drops after exercise.
The pulse (usually taken in the wrist) measures the heart rate.
No, it measures your heart rate. Number of times it beats in a minute.
A heart-rate monitor is used.
A continuous heart rate monitor constantly measures the heart rate. Typically, these monitors have a chest strap that transmits the heart rate to a wrist watch continuously over the period of workout. A non-continuous monitor is a monitor that has to be told to measure the heart rate. These monitors are typically watches without a chest strap. The user measures the heart rate by pushing on the watch so that firm contact is made with the user's pulse. The watch then displays the heart rate while the user pushes on the watch.
A heart rate monitor is a device that measures the number of times the heart beats per minute. It helps track and monitor heart rate during physical activity by providing real-time data on how hard the heart is working. This information can help individuals adjust their exercise intensity to stay within their target heart rate zone for optimal fitness and health benefits.
Pulse rate(AKA heart rate) is number of beats per minute
A heart rate monitor measures the number of times the heart beats per minute. It helps track and monitor heart activity by providing real-time data on heart rate during exercise or daily activities. This information can help individuals understand their fitness levels, set goals, and ensure they are exercising at an appropriate intensity for their cardiovascular health.
Heart rate monitor is personal monitoring device that measure the heart rate in real time (measuring the number of your heart's beat per minute).
The number of times your heart beats in a minute, the heart rate.
Heart rate is the number of times the heart beats per minute. It is usually recorded as bpm, which stands for "beats per minute".
Pulse
Your target heart rate should be between 75-85% of your max heart rate. To find your max heart rate you take 220 and subtract your age from it to get your max heart rate. Then you can find your target heart rate easily by taking a calculator, typing in your max heart rate, and then type in "subtract (-) 15%". Record that number on a piece of paper of some sort. Then retype your max heart rate and then type in "subtract(-) 25%". Also record that number down on the same piece of paper you wrote the original number on and put a dash (-) between the numbers. This will show you the two numbers your target heart rate should be in-between.
