Studies Participants And Exercise
Initially based on database queries and through screening of additional sources 15,992 articles have been identified and included in the screening process. After exclusion of 660 duplicates, 15,332 articles have been screened. Finally, the literature search yielded 191 studies meeting the eligibility criteria. Ten of these articles presented the same data as presented in another article and therefore were excluded. Thus, finally the data of 181 articles encompassing 215 samples were included in the meta-analytical synthesis. The selection process of the articles included in this systematic review is presented in and detailed descriptions of the 215 samples included in the meta-analysis are presented in .
All studies included have been published between 1971 and 2018. Altogether, 12,952 individuals were incorporated in the intervention and control groups . The sample sizes of these groups ranged from 5 to 1456 within the studies with a median sample size of 17 participants . Of the 215 comparisons 92 included both female and male participants, whereas 65 only included females and 58 only males. Wiley et al. did not report the gender of their participants . This study was considered in the group of studies including both sexes.
What Your Heart Rate Can Signal
During cardiac assessments, experts often take into account resting heart rate, how quickly it increases during physical activity, heart rate recovery and heart rate variability, said Daniel Cantillon, the associate section head of cardiac electrophysiology and pacing at the Cleveland Clinic.
For most people, it is considered normal to have a resting heart rate when the heart is pumping the lowest amount of blood you need between 60 and 100 beats per minute, according to the American Heart Association. Generally, a lower resting heart rate is associated with higher cardiovascular fitness. Some athletes, for instance, have resting heart rates well below 60.
A low resting heart rate can indicate a heart thats physically fit, Martin said. If your hearts in good shape, with each beat of the heart then youre pumping blood efficiently to the rest of your body.
If, on the other hand, a person at rest has a high heart rate, that indicates that the hearts working harder than we would expect it to have to work at that state, he said.
Another marker that can be tracked with technology is heart rate variability, or a measure of the variation in time between each heartbeat. A fair amount of heart rate variability, Cantillon noted, can indicate a healthy autonomic nervous system.

Measuring Your Heart Rate
Watch any medical drama on TV and the first thing youll see the doctor do is measure the patients heart rate. Firstly because yes, it means theyre alive! Secondly, because our heart rate reveals so much about our general health and fitness. For example, a weak pulse or a racing heart rate can be a sign to a medical professional that something is not right.
So what exactly are they checking? By definition, your heart rate means the number of times your heart beats in a minute. The two most common ways to describe heart rate are:
- In beats per minute .
- As a percentage of your maximum heart rate .
Can Your Heart Rate Increase Too Fast During Exercise
Most people cannot exercise a healthy heart too much. Exercise is what causes your heart to get stronger and stay healthy. However, if you have any kind of heart disease or potential heart complications, then exercising too much can be dangerous.
You should never embark on an exercise routine without a doctors permission. If you have any heart problems your doctor can guide you to appropriate exercises for your condition.
Any heart condition, a stroke, chest pain, easy breathlessness, or high blood pressure are all reasons to consult with a physician. You may also need to discuss any conditions related to your joints or muscles before starting any type of vigorous exercise.
Whenever you are exercising you should pay attention to how your body feels. Endorphins are released during exercise, which causes you to feel good and stimulates you to continue. If you start feeling tired it is a sign that you are losing energy and your muscles may not be getting their required oxygen.
If you have a hard time carrying a conversation, feel faint or dizzy, or develop any type of chest pain then you should stop exercising immediately and seek medical assistance. Whenever you are exercising it is better to use caution.

Heart Rates And Exercise Intensity
Because heart rates vary so much between people many trainers use the Rating of Perceived Exertion scale to measure and set exercise intensity with clients.
The RPE scale is a simple 1-10 scale where the client rates the intensity of the exercise according to how hard it feels to them.
If you were aiming to take a new, unfit client through a low-moderate intensity cycling workout and they rated the workout at 7 it would indicate that youd exceeded the intensity you planned !
The RPE scale is an easy client friendly way of measuring intensity according to the clients feedback and providing direction to clients regarding the intensity they should train at.
What direction do you think a client would find easier to understand jog at an intensity of 3/10 that you feel is light for 30 minutes, or jog at a point where your heart rate is between 120-135 bpm for 30 minutes?
Your Target Heart Rate
Because hanging out in the max zone for too long can be dangerous, you need to find a range that’s both safe and intense enough to give you a good workout that’s where your target heart rate zone comes in.
According to the AHA, your target heart rate zone during moderate-intensity exercise is about 50 to 70 percent of your max heart rate. If you want to work at a vigorous level, you bump the range up to 70 to 85 percent of maximum.
Additionally, you can skip the math session and use one of the online calculators to do the calculation for you. The American Council on Exercise has one that calculates your target heart rate range based on whether you’re at a beginner, intermediate or advanced fitness level.
The bottom line: It’s always important to consult a doctor before starting any new exercise program, especially if it’s strenuous. In some cases, a visit to the doctor is especially important before engaging in activities that will raise your heart rate to the top of the recommended cardiovascular zone for your age.

Aerobic Exercise For Heart Health
Your heart is made up of cardiac muscle. This specialized tissue takes on electrical and neurological signals so that it can pump blood for the entire life of the organism. If you really think about how the heart never stops to take a break, its an amazing tissue within the human body.
Taking care of the heart should be your top priority. Its important to work the heart and raise the heart rate. Remind yourself that the heart is a muscle, which can be exercised just as easily as the biceps or triceps.
When your heart rate increases from a resting state, the muscle is exercising at a more intense rate than before. As a result, the heart gains strength and resiliency through the effort.
What Is Target Heart Rate
Your target heart rate is a range of numbers that reflect how fast your heart should be beating when you exercise. A higher heart rate is a good thing that leads to greater fitness, says Johns Hopkins cardiologist Michael Blaha, M.D., M.P.H. During exercise, you can monitor heart rate and try to reach this target zone. Doctors also use target heart rate to interpret the results of a cardiac stress test.

How High Can You Go
If you’re an athlete or serious fitness fanatic, you might like to take your body to the brink to see how it performs. If that’s the case, your heart and lungs are likely conditioned to handle this extreme level, even if it’s just for a brief period of time. But if you’re an average gym-goer, runner or cyclist, you might be wondering how high is too high for you.
According to Dr. Doshi, there is no “single danger zone.” How high you take your heart rate during exercise, he says, depends on several variables, including your fitness level and underlying medical problems. “You need to listen to and understand your body when pushing the limits,” Dr. Doshi says. And be aware of symptoms such as severe shortness of breath, chest pain, dizziness or severe heart palpitations, which “are all signs that you need to slow down,” he adds.
Although you can go over the “theoretical calculated maximal heart rate,” Dr. Doshi says it’s important to note that this formula generalizes people and doesn’t correct if you’re an older athlete or an extremely fit person. Thus, Dr. Doshi recommends discussing your needs with your doctor or health care provider. If you’re new to exercise or have a medical condition, they can help you determine a safe zone for getting started.
If you want to train at your maximal heart rate, consider consulting an exercise physiologist who can help you find your baseline max heart rate and monitor you while you exercise.
Why Is My Heart Rate So High When Exercising
During cardio exercise such as running, your heart rate increases. Your heart rate while running can be a good measurement of how hard youre working. As your pace and work rate increase, so does your heart rate. Blood circulates to your muscles so they can get the oxygen and nutrients they need to keep going.

Getting To The Heart Of It: Cardio Fitness Your Heart Rate And What To Aim For During Exercise
By health reporter Olivia Willis
It will beat around three billion times over your lifetime, without you even having to think about it.
Every day, your heart pumps blood through a system of blood vessels over 100,000 kilometres long, providing your body with the oxygen and nutrients it needs to function.
It’s nothing short of miraculous. But how fast your heart beats depends on a few things, including your age, medical conditions, and overall fitness level.
Thanks to smartwatches and fitness trackers, you can now monitor your heart rate more easily, particularly during exercise.
But what constitutes a ‘normal’ heart rate? And is there much to gain from tracking it?
Why Does My Resting Heart Rate Fluctuate
You now know that there are many factors that can cause resting heart rate fluctuations. Its important to think about all of these if you observe any resting heart rate changes, as its likely to be a short term change. Its relatively normal if your RHR fluctuates a lot and, for example, you are having a varied sleep pattern, experiencing stress, taking medication, changing your training schedule, or are affected by hot weather.
There is a wide range of normal when it comes to your RHR so yours fluctuate, it wont often be cause for concern. However, if your RHR is consistently over 100 beats per minute, then you could have tachycardia, which could be caused by a heart rhythm disorder. Alternatively, if youre not a trained athlete and your RHR is below 60 beats per minute and you are dizzy or short of breath, you could have bradycardia. In either of these cases, its important to speak to a doctor so they can look at why your RHR fluctuates.

How To Monitor Heart Rate
Once a person has calculated their target heart rate zones, they can find out whether or not they are meeting these ranges by measuring their heart rate while running.
The most basic method for testing heart rate is to count pulse rate by hand. To do this, a person can place two fingers lightly on the opposite wrist until they can feel the pulse.
Count the number of pulse beats that occur in 30 seconds and multiply this by two to find out the number of beats in 60 seconds.
An easier way to measure heart rate during exercise is to wear a wristwatch or chest monitor that picks up on heartbeat. There are many products to choose from, such as heart rate watches and heart rate straps, online.
Otherwise, it may be a good idea to book some time with a treadmill or a personal trainer to get accurate heart rate readings and set goals.
Although an increased heart rate is one aim of exercise, pushing the heart too far can be harmful.
Signs that a person is pushing their heart too far include chest tightness, difficulty breathing, and a relative inability to talk while running.
If a person notices any of these signs, they should slow down and concentrate on breathing steadily. If a person always experiences chest pain with exercise, they should seek a professional medical opinion immediately.
It is important to note that these target heart rates are for average individuals who are otherwise healthy.
What Your Resting Heart Rate Can Tell You About Your Fitness
One of the often-highlighted features of the new iteration of the Apple Watch is its ability to track your resting heart rate . Fitbit, Garmin, Samsung, and other tech brands also offer fitness trackers that measure your heart rate during exercise and keep tabs on your resting heart rate throughout the day.
We know that heart rate during exercise can show you how intensely youre workinga higher heart rate means youre putting greater demands on your cardiovascular system, and therefore, your heart is working really hard to pump blood quickly enough to meet those demands. The importance of resting heart rate is a little more vague, but this number can actually give you some insight into your fitness level and how its changing over time.
In addition, it could give your doctor information that, combined with other factors, may signal a heart problem.
Now, its important to first note that you should never rely on a fitness tracker to diagnose a potential heart condition. Only a doctor can make a diagnosis . Trackers are not medical devices and the accuracy from tracker to tracker varies greatly. Wrist heart rate monitors can be used to glean insights into your stats, but are never a substitute for seeing a doctor and getting advanced screenings done if you are concerned that something might be wrong. That being said, these devices may be helpful in spotting overall trends and big picture changes that are worth talking to your doctor about more.

Why Does Heart Rate Increase During Exercise
If youve ever wondered why your heart rate increases during exercise, then you should know that while you exercise, or carry out any vigorous physical activity, your muscles require a large amount of energy. Although the muscles can get some energy by carrying out anaerobic metabolism, the majority of their energy needs are fulfilled by aerobic metabolism, which cannot be completed without oxygen. Since your bloodstream is responsible for bringing the oxygen to your muscles, your heart needs to pump a great amount of blood for maintaining the oxygen supply to the muscles that are working. To fulfill this goal, the heart starts beating rapidly and forcefully, which increases the heartbeat.
In addition to that, if you are exercising on a hot day, then too, the high temperature coupled with the vigorous activity performed by your heart will result in an abnormal increase in your heart rate. This happens because the heart needs to supply blood to the skin for cooling you down and it also needs to supply the blood to the working muscles. These two changes require the heart to beat quickly than usual. People who train a lot in hot environments become quite efficient at cooling their bodies.
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.
