What Is The Heart Rate
Heart rate or pulse rate is the number of times your heart beats in a minute. It is a simple measure to know how much your heart works during rest or activities.;
Heart rate is one of the vital signs that are checked regularly whenever you visit your doctor, or when you get admitted to the hospital.
Your heart rate is lower when you are resting and higher when you are doing any kind of activity, or are feeling stressed or anxious.;
When you exercise, your heart needs to work harder, which increases your heart rate. As soon as you rest, the heart rate starts decreasing gradually and returns to its normal level, usually within an hour.
Ask The Coaches: Heart Rate For A Marathon
Q: I would like to know what percentages of my max heart rate I should be running at race pace for the marathon.
A: There is no specific target heartrate zone for marathons, since it depends on how fast you are willing to run. Joggers can finish marathons while never exceeding 65-70%, while the average Kenyan is probably running the whole distance at several beats above 85%.
To have at least a slight idea of your zone for race day, do some planned Marathon Pace runs at exactly race pace of from from five to ten miles, to establish a likely zone. Even knowing this, however, I don’t recommend running a whole marathon on just HR’s because it is a very tricky matter that could lead to positive splits and a real head banger crash into the wall if you are unfamiliar with what you are doing.
On race day, a number of Magic Intangibles affect your heart rate. These intangibles, including your taper, carbo loading, aid stations and fellow runners at your pace, will make it possible for you to run easier at goal pace than you have in practice. Your HRM reads lower than expected, so you speed up to bring your HR up to the goal range, and pay for it later when you run out of glycogen and have to slow.
The solution then is to not run a marathon on effort alone until you have run several and have correlated your training heart rates with your actual rates at each mile on marathon day.
Food As Fuel Before During And After Workouts
Your body is your vehicle, so you have to keep your engine running when you work out. That means fueling up your body by eating the right foods and drinking the right fluids, in the right amounts at the right times.
The American College of Sports Medicine says, Adequate food and fluid should be consumed before, during, and after exercise to help maintain blood glucose concentration during exercise, maximize exercise performance, and improve recovery time. Athletes should be well hydrated before exercise and drink enough fluid during and after exercise to balance fluid losses.You dont have to adhere to a rigid schedule and there are no hard-fast rules, said Riska Platt, M.S., R.D., a nutrition consultant for the Cardiac Rehabilitation Center at Mount Sinai Medical Center in New York. But there are some things you should do before, during and after you work out.

What Causes An Increase In Heart Rate And What Is The Maximum Heart Rate
When your body is doing a certain physical activity such as walking, a workout or an exercise session, it means that your muscles, tissues and other parts of the body are in a larger requirement of oxygenated blood. In order to fulfill this requirement, your heart has to pump faster and larger portions of blood to the various parts of your body.
This increases the heartbeat to various levels. The ideal heartbeat rate which it should be at its maximum level will differ from person to person. The two factors of weight and age happen to play a very important role in this context. It is said that the ideal limit of your maximum heart rate is your age subtracted from the number 220.;So, if your age is 30, then the maximum heart rate that you can attain is 220-30 = 190. It is obvious that the maximum heart rate is something that will differ from person to person, depending on their age.
Know Your Numbers: Maximum And Target Heart Rate By Age
This table shows target heart rate zones for different ages. Your maximum heart rate is about 220 minus your age.3
In the age category closest to yours, read across to find your target heart rates. Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate, while during vigorous physical activity its about 70-85% of maximum.
The figures are averages, so use them as a general guide.

How To Lower Your Heart Rate
Staying physically active by doing moderate to vigorous exercise regularly is one of the best ways to achieve a lower heart rate that leads to a healthy and long life.
Changes in your lifestyle that may lower your heart rate include:
- Reducing the intake of coffee and caffeine-containing products
- Avoiding binge drinking
- Intake of a healthy diet to keep weight under check
- Doing deep breathing to manage stress and anxiety
If your heart rate becomes too high suddenly, and you feel shortness of breath or chest pain, you need to consult your doctor immediately to get medications prescribed for you. This could be a sign of an impending heart attack or other life-threatening heart problems.
What Can Resting Heart Rate Readings Indicate
Resting heart rate is an indicator of fitness and general health. They are:
- In adults, a lower heart rate is correlated with a higher degree of fitness and a lower incidence of cardiac events, such as heart attacks.
- Highly trained athletes can have an RHR as low as 40. This may be because the lower rate translates to a heart muscle that is stronger and can pump blood more efficiently. Another explanation is that with vigorous exercise, there is the release of nitrous oxide in the hearts blood vessels, which increases the blood supply to the heart.
- However, a consistently higher heart rate has been associated with cardiovascular issues and premature death.
- A 2013 research that studied 3000 men for 16 years found that men with RHR greater than 90 were associated with triple the risk of death when compared to men with RHR below 80.
- An observational study conducted in Norway that looked at 20,000 participants found similar results, even when controlled for factors, such as body mass index and life.
ByJoshua A. Krisch05 February 2020
A study of more than 90,000 people with smartwatches reveals that resting heart rate can vary between individuals by up to 70 beats per minute.
Most healthy people experience little variation in their heart rates at rest, but a new study shows that normal resting heart rates can differ between individuals by an astonishing 70 beats per minute.;

Measuring Your Target Heart Rate
There are several ways to measure your heart rate:
- Resting heart rate – Your heart rate when youre not doing any activity.
- Maximum heart rate – The highest number of times your heart can beat in one minute.
- Target heart rate – The rate your heart should beat during exercise in order to get the most improvement in aerobic capacity . This is usually expressed as a range.
Your target heart rate is a percentage of your maximum heart rate. So to calculate your target heart rate, you have to first find out what your maximum heart rate is.
To calculate your maximum heart rate, use the following equation:
- HRmax = 208 )
This formula has proven to be accurate regardless of gender or current physical activity levels.
To calculate your target heart rate, use the following equations:
- During light intensity activity – Target heart rate is between 45% and 54% of your HRmax
- During moderate intensity activity – Target heart rate is between 55% and 69% of your HRmax
- During high intensity activity – Target heart rate is between 70% and 89% of your HRmax
For The Best Workouts Know Your Target Heart Rate
We know exercise is good for us and has been shown to have many mental and physical health benefits, including burning calories to help lose weight. If your goals for exercise include weight loss, how do you know if youre doing too much or not enough? One way is to monitor your heart rate, which is the number of times your heart beats per minute whether you are at rest watching TV or hard at work climbing a mountain.
Although a normal resting heart rate can range from 60 to 100 beats per minute, UNC cardiologist Christopher Kelly, MD, says a resting rate of 60 to 85 is typically the norm.
The truth is that for most people, a normal resting heart rate is probably 85 or less, Dr. Kelly says. Having a heart rate of 99 when youre sitting, resting and minding your own business, although technically defined as normal, is really not.

Other Factors That Increase Your Heart Rate
In addition to exercise, there are other things that can increase your heart rate, including
stress, uncontrolled anxiety and poor sleep habits. These will all increase your adrenaline levels and your resting heart rate. Drinking caffeine and alcohol also will increase your resting heart rate.
Some medications or medical conditions, such as hyperthyroidism or anemia, can speed up your heart rate, and this means you may have a lower maximum heart rate and target heart rate zone.
Heart failure also can cause an abnormally elevated resting heart rate.
If the heart is not pumping as much blood each time it contracts for a variety of reasons, it will compensate for that fact by getting faster so that the total overall blood being pumped per minute is the same, Dr. Kelly says. If each pump yields less blood, then itll just pump faster so that the total amount of blood being pumped doesnt change.
If you have a heart condition or take medication for anemia or hyperthyroidism, ask your healthcare provider what your heart rate should be.
How High Should The Maximum Heart Rate Be
8. November 2017
The faster our athletic activities, the higher the heart rate increases until it cant go any higher. But which maximum heart rate is normal, which is good – and which is dangerous?
Right at the outset its important to remember: the human heart beat is as individual as the person carrying the heart. If two equally heavy and equally fit people of the same sex run beside each other equally fast, this does not mean that their heart rates will also be the same.;
Thus, the maximum heart rate – i.e. the heart rate that can be achieved through the maximum level of exertion – is also individual and not a measurement that can reveal something about the level of fitness. The maximum heart rate depending on your form on the day is not always the same and can vary significantly from day to day. Some people mostly younger people can easily push their heart rate to over 200 beats per minute, while others already reach their limit with a heart rate of 170. However, this does not reveal anything about whether the person with a maximum heart rate of 220 is fitter than the one with a maximum heart rate of 180.;
A working heart rate refers to the difference between the maximum heart rate and resting heart rate. An athlete with a maximum heart rate of 200 and a resting heart rate of 40 thus has a working heart rate of 160 beats.

What If My Resting Heart Rate Is High; Does The Same Formula Still Apply
Even if your resting heart rate is higher, say 90 beats per minute, the same formula still applies to you. What this means, however, is that you have less room to move in terms of reaching your maximum safe heart rate.
Studies show that a resting heart rate of over 84 may be dangerous and having a medical exam is important to ensure that you dont have any underlying issues causing the accelerated rate.
If you have had a higher heart rate your entire life, then it is likely that you simply have a high heart rate, but it is always best to err on the side of caution and get a medical opinion.
Does Your Heart Have A Maximum Number Of Beats
The maximum number of lifetime heartbeats for humans is about 3 billion. But you wont die when you reach a set number of heartbeats. Heartbeats, however, are a marker of your metabolic rate. The faster your metabolic rate , the shorter your lifespan.
The total number of heartbeats per lifetime is amazingly similar across all mammals. For example, a mouse has; a heart rate of 500 to 600 beats per minute but lives less than two years. At the other extreme, a GalÃ¡pagos tortoise has a heart rate of about six beats per minute and has a life expectancy of 177 years.
Do the math and the heart of a mouse beats 100 times faster than that of a tortoise. But a tortoise lives 100 times longer than a mouse. Humans, however, have about 60 bpm and have about 3 billion heartbeats per lifetime.

What Are Exercise Heart Rate Zones
Heart rate zones are a percentage of your maximum heart rate . Exercise too close to your maximum HR and your heart and body will struggle to keep up with the demands.;
The goal of heart rate zones is to make you the most efficient, but to allow you to challenge yourself to improve cardiovascular fitness, says Travers.;;
Exercise heart rate zones are the training levels based on your maximum heart rate.;As you increase your pace, cadence and workload, you increase the demands on your heart. Travers breaks it down:;
- Lower-intensity zone:;Youre exercising at 50% to 60% of your max heart rate. At this point, 85% of the calories you burn are fat. The downside? Youre burning fewer calories overall than you would if you were exercising at a higher intensity. Youre generally able to sustain this zone the longest amount of time.
- Temperate zone:;Youre exercising at 60% to 70% of your max heart rate. Roughly 65% of the calories you burn are fat.
- Aerobic zone:;Working at 70% to 80% of your max heart rate puts you in the aerobic zone. About 45% of the calories you burn are fat. But youre burning a higher number of overall calories compared to the other heart rate zones. You generally sustain this zone the shortest amount of time.;
What Should My Heart Rate Be During Rest And Exercise
There are so many reasons why you may want to learn more about your heart rate. If you wanted to gage your heart health or if you are an athlete and training for optimal performance then its great to monitor heart rate!
Understanding heart rate during rest and exercise can help determine heart health and determine where your fitness level is. During exercise, your heart rate is important to know for safety and may help enhance your results. Ill break it down for you below.
Note: For most healthy individuals it is not essential to track heart rate.

What Is A Normal Or Resting Heart Rate
There are three general ways to classify;heart rate, 1) normal, 2) fast and 3) slow.
- A resting heart rate is normal between 60-100 beats per minute.
- A resting heart rate is fast at greater than 100 beats per minute.
- A resting heart rate is slow at less than 60 beats per minute.
A resting heart rate predicts longevity and cardiovascular disease, and current evidence suggests that it is also an important marker of outcome in cardiovascular disease, including heart failure. A normal heart rate is generally stated to be between 60-100 beats per minute at rest . However, recent studies have suggested that an ideal resting heart rate is between 50-70 beats per minute. It is well-known that the average resting heart rate for well-trained athletes is between 40-60 beats per minute! A heart rate can change dramatically while sleeping or with daily activity and exercise. Usually, a heart rate will be slower during sleep, faster during daily activities or with exercise, and recover quickly back to a resting rate after exercise. This means your heart has appropriate heart rate variability and recovery, which is associated with good heart health. Your resting heart rate can also be used to estimate how much energy your body uses, or your basal metabolic rate.
