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.
How To Check Your Heart Rate
Checking your heart rate can be done anytime, anywhere and doesnt cost a dime. The first step is to find your pulse. You can try the wrist, inside of the elbow, side of your neck, or top of your foot. These are usually the easiest places to feel the pulse. To get the most accurate reading, put your finger over your pulse and count the number of beats in 60 seconds. If youre under 100, youre probably good to go. If youre higher than that, its time to lower your heart rate.
Defining Maximum Heart Rate
According to the American Heart Association your maximum heart rate is the number of heart beats you have per minute when you are at your highest exercise ability. But, as Dr. Singh point out, you only want to reach whats called your target heart rate 60 to 80 percent of that number. Also, this range gradually lowers with age.
To find the target heart rate range for your age, subtract your age from 220 and then multiply that number by 0.60 and by 0.80 to find the low and high ends of the range. If you are 40 years old, for instance, this formula will tell you that your target range for healthy exercise is about 108 to 144 beats a minute.
Increasing your heart rate during exercise is the best way to increase your heart strength and lower your risk for heart attack, according to Harvard Health Publishing. If you exercise a lot and are in excellent physical shape, it will take more exercise to get to your target range. If youre new to exercise, your heart rate will increase quickly with less exercise.

The Key To Lowering Resting Heart Rate
The subject of athletics has not been understood until recently nor has the best method of training been investigated, Dr. Sargent told a Harvard audience on March 6, 1896. Dr. Sargent seems to be suggesting that everything about athletic training was now settled. 121 years later, however, there is still so much to learn about our amazing bodies, and how to maximize what they can do.
One useful measure is resting heart rate . A low RHR is the hallmark of cardio health. RHR is just what it sounds like, the measure of how many times your heart beats when you are at rest. , which measures the variation between beats.)
A normal resting heart rate for adults ranges from 60 to 90. When it comes to RHR, it important to know how to lower resting heart rate. Elite athletes have RHR in the 50s, 40s, even 30s. High RHR is associated with an increase in risk of death. But can you change your RHR? If so, how? And by how much?
Data Management And Data Extraction
After checking the potentially relevant primary studies according to the eligibility criteria mentioned above, the articles were additionally checked for double publication. The following data was extracted from each primary study included in this systematic review: author year of publication number, gender, and age of the participants type of sports/exercise duration of the intervention frequency of exercise sessions method of RHR measurement randomisation blinding RHR at the beginning and end of the interventional period in the intervention and control groups, resp.
In case of studies with more than two arms , those comparisons with the higher exercise intensity, duration or frequency, continuous and concentric strength training, land-based training, and jogging/running were considered for the meta-analyses. Additionally, if both pre and post-menstrual or pre and post-menopausal RHR results were presented, the first ones were included in the meta-analyses.

If your heart is racing as youre sitting reading this article, its possible your body is trying to tell you something. A high resting heart rate, or a heart rate of more than 100 beats per minute, means your heart is working extra hard to pump blood through your body. And, that extra effort could result in a wide range of negative effects on your overall health, including feelings of dizziness and fatigue and most seriously blood clots, heart failure and, in rare cases, sudden death.
Normal resting heart rate is anywhere between 60 and 100 beats per minute, and its simple to check how fast yours is beating. While idle, hold your pointer and middle finger between your bone and tendon on the thumb side on your wrist until you feel your pulse, and count the number of beats for a minute that is your resting heart rate.
Certain aspects of someones resting heart rate are directly connected to uncontrollable factors, such as age and genetics, however there are certain actions that be taken to help decrease heart rate and improve overall wellbeing for those whose resting heart rate is above normal.
Here are six proven ways to lower your resting heart rate:
Target Heart Rates Chart
What should your heart rate be when working out, and how can you keep track of it? Our simple chart will help keep you in the target training zone, whether you want to lose weight or just maximize your workout. Find out what normal resting and maximum heart rates are for your age and how exercise intensity and other factors affect heart rate.

Target Heart Rate And Estimated Maximum Heart Rate
For moderate-intensity physical activity, your target heart rate should be between 64% and 76%1,2 of your maximum heart rate. You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 50 years = 170 beats per minute . The 64% and 76% levels would be:
- 64% level: 170 x 0.64 = 109 bpm, and
- 76% level: 170 x 0.76 = 129 bpm
This shows that moderate-intensity physical activity for a 50-year-old person will require that the heart rate remains between 109 and 129 bpm during physical activity.
For vigorous-intensity physical activity, your target heart rate should be between 77% and 93%1,2 of your maximum heart rate. To figure out this range, follow the same formula used above, except change 64 and 76% to 77 and 93%. For example, for a 35-year-old person, the estimated maximum age-related heart rate would be calculated as 220 35 years = 185 beats per minute . The 77% and 93% levels would be:
- 77% level: 185 x 0.77 = 142 bpm, and
- 93% level: 185 x 0.93 = 172 bpm
What Is The Best Exercise For Heart Rate
While interval-style exercise training is a popular choice for people who are time-poor, the intermittent nature of the exercise means heart rate will fluctuate, providing not much more benefit than traditional steady-state exercise.
From a scientific perspective, athletes typically use heart-rate ranges to train at specific intensities during aerobic exercise, like cycling or long-distance running.
Exercising at certain intensities are known to elicit adaptive responses from the body, for example, exercising at or below the lactate threshold.
These intensities are called training zones and are expressed relative to HRmax. For instance, a light aerobic training session would be prescribed below 75% HRmax, while training at threshold will induce physiological change.
Overall, some exercise is better than no exercise for your cardiovascular health. Accumulating 150 minutes of exercise per week is the minimum requirement for health benefit. Exercising at your maximal heart rate is not necessary to achieve these benefits. Athletes can use training zones, relative to HRmax, to achieve optimal adaptation and enhance endurance performance.
Is Exercising At Maximal Heart Rates Unsafe
In short, the answer is no. For most adults, the risk of not doing enough exercise is far greater than that of doing excessive endurance exercise.
The health benefits of regular exercise are well established, although emerging evidence suggests excessive exercise may not provide extra cardiovascular health benefits.
Likewise, theres a higher chance a sedentary person will experience an acute cardiac event, like a heart attack, during exercise when theyre unaccustomed to high-intensity exercise, or they have a pre-existing heart condition. The maximal risk is 0.3 to 2.7 events per 10,000 person-hours.
With a third of Australians not meeting the WHO recommended guidelines of accumulating 150 minutes of exercise per week, encouraging regular physical activity continues to be a pervasive public health message.
In terms of assessing risk, an exercise pre-screening assessment with an ESSA-qualified exercise specialist will be able to assess and mitigate the risk of exercise participation.
What Is A Normal Heart Rate
A normal resting heart rate usually sits between 60 and 100 beats per minute. Anything that is consistently over 90 beats per minute warrants attention from a doctor. If you are very athletic, your heart rate might reach as low as 40 beats per minute. As long as your heart rate is within the normal range, you probably have good heart health. Anything over that, however, is enough to make you take notice.
When to Consult a Doctor
Remember that there is a wide range of what is a normal heart rate. If you want to learn how to lower heart rate, speak to your doctor first about the existing resting heart rate you have and then ask for specific advice on how to bring it down. Remember that you should never embark on an exercise program or other options to bring down your heart rate without the okay from your physician.

Exercise Intensity: What Happens When We Go All Out
Muscle cells require two key ingredients to function: fuel and oxygen.
Muscles rely heavily on blood vessels to deliver the necessary nutrients and oxygen around the body, and also to remove by-products such as carbon dioxide.
The more muscles used in exercise, the more blood is distributed towards the active tissues.
When the intensity of the exercise is particularly high, the muscles start to produce another by-product called lactate.
Cells can also use lactate as a fuel although if production rate exceeds metabolism, lactate starts to accumulate and can interfere with cellular function.
The point at which this by-product starts to accumulate is termed the lactate threshold.
Any exercise intensity that can be comfortably sustained is usually below this threshold, and will have an accompanying heart rate. As it is much easier to measure heart rate than lactate production, heart rate can be used as a surrogate measure of exercise intensity.
Bradycardia Causes + 9 Natural Ways To Improve Slow Heart Rate
If your heart beats less than 60 times each minute, you have bradycardia. This condition can also be referred to as sinus bradycardia. At rest, an adult heart typically beats between 60 and 100 times a minute anything lower may be a sign of an underlying medical condition. It can be a serious condition if your heart isnt pumping enough blood throughout the body.
There are, of course, exceptions. Young adults and premier athletes may have a resting heart rate of less than 60 beats a minute and this is generally not considered a health concern. Bradycardia symptoms can range from mild to severe, particularly when your brain, liver, kidneys and other organs arent getting enough oxygen.
Several conditions can cause bradycardia, including several potentially serious conditions, such as myocarditis, sleep apnea, lupus or certain medications. Bradycardia treatment depends on the underlying cause of the low resting heart rate but may also include the surgical placement of a pacemaker.
If you become suddenly faint, have difficulty breathing or experience chest pains, call 911 immediately.

Stretching Flexibility And Balance
What they do: Flexibility workouts, such as stretching, dont directly contribute to heart health. What they do is benefit musculoskeletal health, which enables you to stay flexible and free from joint pain, cramping and other muscular issues. That flexibility is a critical part of being able to maintain aerobic exercise and resistance training, says Stewart.
If you have a good musculoskeletal foundation, that enables you to do the exercises that help your heart, he says. As a bonus, flexibility and balance exercises help maintain stability and prevent falls, which can cause injuries that limit other kinds of exercise.
How much: Every day and before and after other exercise.
Examples: Your doctor can recommend basic stretches you can do at home, or you can find DVDs or YouTube videos to follow . Tai chi and yoga also improve these skills, and classes are available in many communities.
What’s the Best Exercise for Weight Loss?
Both aerobic exercise and resistance training burn calories, as well ashelp improve your baseline metabolic rate. The more muscle mass youdevelop, the more calories you burn, says Johns Hopkins exercisephysiologist Kerry J. Stewart, Ed.D. Together with diet, thats what leadsto weight loss, he says.

If you have a new or existing heart problem, it’s vital to see a doctor. Our heart health checklist can help you determine when to seek care.
Normal Resting Heart Rate
A healthy resting heart rate for adults is 60 to 80 bpm. Adults with a high level of fitness can have a resting heart rate below 60. Some elite endurance athletes have a resting heart rate below 40.
An average adult resting heart rate range is 60 to 100 bpm. The higher end of the range is associated with increased health risks including metabolic syndrome.
An elevated resting heart rate of 80 bpm or higher can be an indicator of increased cardiovascular risk and all-cause mortality risk. The risk is most pronounced when the resting heart rate goes above 90 bpm.
Resting heart rate varies by sex. Women tend to have smaller hearts and lower blood volume and hemoglobin, which means the heart needs to beat more frequently to nourish the body’s tissues.
A person’s average resting heart rate also changes from throughout the lifespan, being much faster in infants and slowing by adulthood. The average ranges also change slightly as you age.
Your resting heart rate can also be affected by any medications that you take. For example, beta-blockers and calcium channel blockers can lower your resting heart rate below 60, while medications to treat asthma, depression, and attention deficit disorder might raise it.
Talk to your doctor if you do not actively exercise but you have a low RHR with symptoms of dizziness or shortness of breath.
When someone who is not an athlete or at a high level of fitness has a low resting heart rate , it can be a sign of a medical or health problem.

/10the Normal Heart Rate
Your pulse rate is defined as the number of times your heart beats per minute when you are resting. For an average adult, it is somewhere between 60 to 100 beats per minute. However, the number can vary from person to person depending on several factors like age, sex, health conditions, body size and medications. Our heart rate fluctuates throughout the day depending on our emotions, physical activity and temperature.
High Resting Heart Rate: Should You Worry
In general, a slower resting heart rate is a sign of good health. Some athletes and people who are very active even have heart rates that dip below 60 when theyre at rest.
A high resting heart rate, on the other hand, can be an indicator of problems such as:
- Poor physical condition.
- Thyroid problems.
Often, a high resting heart rate is a sign that your heart is working harder than it needs to. Like any muscle, the heart doesnt work as well when its out of shape. In people who arent very active, the heart isnt as efficient. It has to work harder to pump blood through your body, Dr. Singh says.
