What Is A Normal Resting Heart Rate

Why do Athletes Have Low Heart Rates? (Explained in 30 Seconds!)

With any aspect of human physiology, it can be irresponsible to paint anything as either normal or abnormal. Itâs typical for athletesâ resting heart rate to be lower at rest than the general population, for their maximum capacity to be higher, and for them to be able to do more work at a lower heart rate than an untrained person. As a result, itâs common to find resting heart rates in the 40 to 60 beats per minute range, and if you train elite athletes, a couple might even dip below that. Women typically have slightly higher RHR than men because their hearts are usually smaller and so need to pump faster to output a similar amount of blood. This isnât just true of sedentary people but also athletes, with WHOOP reporting that the average male who uses their technology has an RHR of 55.2, with the average woman at 58.8.

Quick Answer: Why Do Athletes Have Lower Resting Heart Rate

  • Posted On:

Thats likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles. This means the heart beats fewer times per minute than it would in a nonathlete.

Athlete Resting Heart Rate

An athletes resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm.

Thats likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles.

This means the heart beats fewer times per minute than it would in a nonathlete. However, an athletes heart rate may go up to 180 bpm to 200 bpm during exercise.

Resting heart rates vary for everyone, including athletes. Some factors that could influence it include:

  • age
  • air temperature
  • emotion
  • medication

What Is The Fat

Exercising in the fat-burning zone may not be the best way to lose weight.

On large fitness equipment and some fitness trackers, you might notice something called the fat-burning zone. The fat-burning zone often refers to zones 2 and 3, where you are working out at a lower to moderate intensity level. In this zone, your body is likely to burn proportionately more calories from fat than from carbohydrates, hence the name.

Does that mean that working out in this supposed fat-burning is the best way to go about losing weight? Not really. Losing weight is a matter of burning more total calories than you take in. At a higher heart rate, youll burn more calories overall , even if more of those calories come from carbs. If your goal is to lose weight, youre better off working at a higher heart rate to burn more calories than you are focusing on burning fat specifically.

Risks Involved With Very Low Rhr

The Benefits of a Lowered Heart Rate

When an athlete has a resting rate of the heart that is lesser than thirty, there arent many risks involved with this condition except that, at times, dangerously low levels of heart rate,i.e., bradycardia, may go undiagnosed, because, it may be assumed that an athletes heart rate is usually low and it is a normal condition. Also, the person has higher vulnerability to severe symptoms of any condition that leads to lesser blood flow to the heart. Thus, this can lead to decreased blood flow to the organs and may even cause occasional fainting spells. If you are suffering from such a condition, then you need to see a cardiologist right away.

There is also a condition known as athletic heart syndrome or athletic bradycardia, which is seen due to rigorous exercise. In this condition, there is cardiomegaly, i.e., an abnormal increase in the size of the heart. This is basically because, when more blood is pumped out, the force of contraction of the left ventricle increases, which is the reason why, it increases in size and leads to cardiomegaly. This neednt necessarily be accompanied by any severe symptoms, however, if there is a heart condition that is leading to responsive cardiomegaly, then it may become difficult to detect and diagnose it.

Why Does Heart Rate Increase When Exercising

Every part of our body needs oxygen and blood at every single second. This need increases when we induce in any kind of physical activity. At the time of exercising, our body needs a much greater amount of oxygenated blood. This is also because during this time our muscles need more energy to respond to the various calls that we make on them to move our body with increased vigor . This is when the heart has to pump more blood into the body parts especially the muscles. This is the why the heart rate experiences a potential increase and eventually the systolic blood pressure also increases. The systolic blood pressure is the blood pressure in the vessels at the time when the heart pumps in the blood into the blood vessels. Hence, this is also an indication that the heart is working harder to pump in a greater amount of blood into the blood vessels and that too at a faster rate.

Athlete Heart Rate Zones

Heart rate, VO2 Max, power , and blood lactate are all methods that endurance athletes use for training. Heart rate training may be the most commonly used method across all demographics and populations. Its convenience, accessibility, and repeatability make it an asset for the time strapped endurance athlete. Heart rate zone training is a very individualized training method because it is based off of your personal maximum heart rate. This allows the individual to accurately train at specific intensities. The convenience makes it particularly useful for junior, para, recreational and masters athletes who may not have access to a physiological laboratory where VO2 Max and blood lactate testing can be done to determine your maximum heart rate and heart rate training zones.

A Little Exercise Provides Great Health Benefits

Hallén does not doubt that good condition is good for your health, but believes it is important to include other goals.

For people who dont want to excel at a specific sport, it may be that getting enough exercise is a little more important than being super fit, Hallén said.

With that in mind, you dont have to train so hard.

To increase your heart size, you probably need to increase your exercise level to a certain intensity, but to improve your health, it is enough to be active, without putting too great of a demand on your body in terms of the intensity, Hallén said.

He cites a Norwegian School of Sports Science study that shows that even a few small steps per day can prolong life.

When To Be Concerned About A High Heart Rate

An abnormally high heart rate is called tachycardia. There are different types and causes of tachycardia. Most have to do with a high resting heart rate. But if you have tachycardia, exercise could be a factor in causing your heart rate to spike.

The more data you have about your resting and maximum heart rate, the more you will know if something isnt right. If your heart rate seems too high for the effort youre making, take note. See if it happens again. Your heart rate monitor may be malfunctioning .

You may also want to consider using your RHR to determine if you are overtraining. Kentaro Onishi, DO, a physiatrist at UPMC Sports Medicine and an avid runner, recommends recording your normal, true RHR before beginning any training program. If your true RHR increases by more than seven BPM after you begin a training regimen, then you may be overtraining. Overtraining should be avoided. It can result in less interest in continuing to train as well as injuries.

If you notice a high heart rate along with dizziness or nausea, stop immediately and call your doctor. Always listen to your body over any piece of wearable technology or a heart rate chart. If something feels off, it probably is. To be safe, its best to talk with your doctor.

The Risks Of Having A Large Athletes Heart

Most data suggests that athletes heart and heart disease are two distinct conditions, and most authors believe that athletic left ventricular hypertrophy is a purely physiological condition.

Its not clear if this means athletes hearts are *healthier*, but it does indicate they arent *less* healthy.

According to Dr. Aaron L. Baggish, the author of a recent review on this topic, athletes heart is most likely a beneficial physiologic adaptation to exercise.

However, there are researchers who disagree. Some data indicates that in certain people, athletes heart might not be completely benign. Its not clear if training caused their heart problems, and theres some question as to whether or not these abnormalities are even problems in the long-run.

There is no direct evidence that the *structural* changes in athletes heart are dangerous.

Nevertheless, there are studies that seem to provide indirect evidence that too much exercise, especially endurance training, can damage the heart and blood vessels, and may cause dangerous heart rhythm disorders.

Higher Heart Rates During Training

Why do Athletes Have Low Heart Rates? (Explained in 30 ...

A second way for you to assess the cardiac efficiency of your athletes, chart their progress, and evaluate the effectiveness of your training programs is to see what their heart rate looks like during various types of training and how it changes over time. There are many different ways to assign different heart rate zones or bands. One of the most experienced players in the heart rate game, Polar, breaks these down as follows:

Is A Heart Rate Of 40 Bad

Some people can have a heart rate of 40 beats per minute and have no symptoms and no long-term consequences. However in other people this can lead to symptoms and require treatment. In some patients a low heart rate is found as part of a routine physical exam or study such as an EKG or a heart monitor.

Why Is It Good To Have A Lower Heart Rate

A lower resting heart rate is better when it comes to your health. Its a sign your heart is working well. When its lower, your heart pumps more blood with each contraction and easily keeps a regular beat. On the flip side, a high resting heart rate may mean your heart works extra hard to pump blood.

Why Endurance Athletes Should Watch A High Heart Rate

Some studies suggest a correlation between endurance training and atrial fibrillation , a potentially dangerous heart condition. This athlete saw the signs early.

Last winter I was on a long base training ride, and I felt generally awful. At first, I blamed my much higher-than-normal heart rate on fatigue, or perhaps a dying HRM battery. But after a couple of days off the bike, and more closely monitoring my heart rate in general, I decided something still didnât seem right.

A visit to my primary care doctor and a quick EKG resulted in a speedy referral to a cardiologist. Long story short, the diagnosis was Persistent Lone Atrial Fibrillation or AFib. âPersistentâ meaning my heart was in a state of AFib all the time âLone or âIdiopathicâ meaning that the cause was unknown.

Atrial fibrillation is a heart condition characterized by an irregular and often rapid heart rate. Its not lethal on its own, but it can increase your risk of stroke, heart failure and other heart-related complications. The American Heart Association estimates that at least 2.7 million Americans are living with the disorder. Traditional risk factors include what most would expect for heart conditions: congenital defects, age, heart disease, excessive stress, and stimulant use. However recent evidence suggests that long-term endurance sports training might also be a significant factor.

How To Determine Your Ideal Exercising Heart Rate

Why does your resting heart rate decrease?

Some athletes like to follow target-heart-rate training. This is based on your intensity level compared to your maximum heart rate.

Your maximum heart rate is considered the highest amount your heart can sustain during cardiovascular training. To calculate your maximum heart rate, subtract your age from 220.

Most athletes train at between 50 and 70 percent of their maximum heart rate. For example, if your maximum heart rate is 180 bpm, your target-training zone would be between 90 and 126 bpm. Use a heart rate monitor to keep track during exercise.

Many Athletes Have A Very Low Resting Heart Rate But That Doesnt Mean That A Low Resting Heart Rate In Itself Means That You Are In Good Condition Says A Professor At The Norwegian School Of Sports Science

Many people use a heart rate monitor as part of their training, and consequently have the ability to monitor their heart rate continuously. If you are part of this group, you might be curious about what your resting heart rate really says about how fit you are.

As is always true in research, the answer is not that straightforward, says Jostein Hallén a professor at the Norwegian School of Sports Sciences.

Some people are simply born with a heart that beats slower at rest than others .

Your heart rate determines how much blood your heartbeat can supply to the body. But even if some of this is determined by your genes, you can influence your resting heart rate with exercise.

Have you ever felt your heart beating quickly during a workout and stopped to check your pulse on your wrist or neck? Your pulse determines your heart rate, or how many times your heart beats in one minute. Pulse rates differ from person to person based on various factors, such as weight and activity level. To get the best results, you should exercise below your maximum heart rate in what is referred to as your target heart rate this will guarantee that you are achieving the ideal intensity level for your goals. Knowing and monitoring your maximum heart rate while youre active can be a powerful gauge of your intensity level and help you to avoid over- or underexercising.

Heart Rate by Age

The traditional method, also known as HRmax, is a simple way of gauging your maximum heart rate. Start by subtracting your age from 220. Then, use the result to calculate your range.

For example, if youre 50 years old, the calculation would be: 220 50 = 170 . To calculate your heart rate on the high end of the suitable range , multiply 170 by 0.75 to get about 128 beats per minute .

Heart Rate by Age and Gender

Heart Rate by Age and Resting Heart Rate

For example, a 50-year-old with a resting heart rate of 65 would calculate as follows:

  • 220 50 = 170 for HRmax
  • 170 65 = 105 for RHR
  • + 65 = about 144 bpm
