    One problem I have always had with Maffetones method: we always hear that we shouldnt use 220 minus your age for a max heartrate guideline; BUT.Maffetone says use 180 minus your age for a guideline instead. Arent we trying to shoehorn individuals with different needs into the same formula in either case?

    Can you help me understand?

    Have just started using Phil maffetones MAF Training method. Iam using this method and run 60 minutes 5-6 days a week. I keep HR under MAF HR I have to do a lot of walking. Infact, my pace while walking is much better than running in this method. Should I walk or continue with run-walk combination

  • Find Your Target Heart Rate

    The AHA breaks down the basics of calculating your target heart rate for exercise. Start by subtracting your age from 220; the resulting number is your maximum heart rate. If you’re 40 years old, it’s 220 – 40 = 180 beats per minute .

    The name “maximum heart rate” is a little misleading, because you don’t actually want to reach that number. Instead, aim for 50 to 70 percent of that number for moderate-intensity physical activity and 70 to 85 percent for vigorous-intensity physical activity.

    Continuing the example, that means for moderate-intensity exercise, a 40-year-old would aim for a heart rate between 180 x 0.5 = 90 bpm and 180 x 0.7 = 126 bpm. For vigorous intensity, that same 40-year-old would aim for a heart rate between 180 x 0.7 = 126 bpm and 180 x 0.85 = 153 bpm.

    But this formula doesn’t account for gender and according to a 2014 summary of research from the American College of Cardiology, men’s and women’s hearts can respond differently to exercise. Based on data from 25,000 patients who underwent stress tests at the Mayo Clinic, the researchers recommended a new formula for calculating your maximum heart rate:

    • For men, expect your maximum heart rate to be 216 minus 93 percent of your age.
    • For women 40 to 89 years old, expect your maximum heart rate to be 200 minus 67 percent of your age.

    What The Results Mean

    A prolonged elevated heart rate after exercise, as confirmed by a slow heart rate recovery, suggests you may be at higher risk of metabolic syndrome or heart problems, but factors like dehydration, excessive fatigue, and stress can affect the results too.

    If you measure your heart rate recovery, make sure youre well-rested and are drinking enough liquids beforehand. The first thing in the morning isnt a good time since most people wake up mildly dehydrated and that will slow heart rate recovery.

    Also, certain medications, like beta-blockers, can affect the results and give you an unreliable reading. Still, its a useful test you can do at home that says something about your future health risks.

    Its best to do the test several times on different days and average the values. Also, recheck your recovery heart rate every few months and record the value. As you become fitter, how fast your heart rate recovers should improve.

    Measuring Heart Rate On The Fly

    You may be sold on the importance of measuring your heart rate, but gaining that knowledge is a bit difficult. Taking your pulse by hand is possible, although its not as precise as other methods.

    Try a cardiovascular machine at the gym. Most of these machines have sensors where you grab on and see the current, heart rate. Use these sensors as a way to guide your workout. You may be surprised at the level of effort necessary to achieve your heart-rate goals. These machines are usually accurate because of their calibration required by the manufacturer.

    Why Train With Heart Rate

    Control of heart rate

    Your heart rate is a useful tool for understanding and improving your fitness level and performance.;Training with heart rate;allows you to monitor and control the intensity of your workouts, allowing for variation in your;training plan.

    Whats An Ideal Target Heart Rate

    Your target heart rate during exercise should be between 50% to 85% of your MHR, depending on what type of exercise you are doing and for what purpose.;

    For example, if you want to improve your endurance, you should do long training sessions at low intensity. If your aim is to improve your cardiovascular health, then;high-intensity interval training; is what you should try.

    Do Emotions Come From The Heart Or Brain

    Psychologists once maintained that emotions were purely mental expressions generated by the brain alone. We now know that this is not true emotions have as much to do with the heart and body as they do with the brain. Of the bodily organs, the heart plays a particularly important role in our emotional experience.

    Is Resting Heart Rate Different By Age

    For most of us , between 60 and 100 beats per minute is normal.1 The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now thats chill!

    When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness and higher blood pressure and body weight.2

    Cardiovascular Drift Explained – Heart Rate INCREASE During a Steady Run

    Heart rate and blood pressure responses to postural change can be measured conveniently on a tilt-table. The patient lies supine until consistent values are obtained for at least 5 minutes. The patient then is tilted to be in a 60-degree head-up position and the heart rate and blood pressure are monitored. The normal decline in systolic and diastolic pressures should not exceed 25 and 10;mmHg, respectively. The heart rate normally increases by about 10 to 30 beats per minute, but the response declines with age.7

    What Does A Prolonged Elevated Heart Rate After Exercise Mean

    What Does a Prolonged Elevated Heart Rate after Exercise Mean?

    When you work out, especially at a high intensity, your heart rate speeds up to deliver more oxygen to your hard-working muscles. The extent to which your heart rate rises varies with your fitness level, age, and the environment youre working out in.

    Some medications, like beta-blockers used to treat high blood pressure, can affect your exercise heart rate. Beta-blockers cause resting heart rate to slow and make it harder to reach your target heart rate during exercise.

    How fit you are matters too. As you become fitter from a cardiovascular standpoint, your heart rate wont speed up as much at a given exercise intensity because your heart has become a more efficient pump and can pump more blood with each heartbeat.

    A normal resting heart rate is between 60 and 100 beats per minute, but during a workout, your heart rate may more than double. This increase in heart rate is normal as your heart speeds up because of the added demands of exercise. After you stop your workout, your heart rate gradually comes down. Once your muscles are no longer working as hard, your heart doesnt need to either, so it slows. In fact, how quickly your heart rate drops after exercise is an indirect marker of heart health. It also says something about how aerobically fit you are.

    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 Get Your Heart Rate Up

    Its essential that some of your exercise make your heart beat fasterthan it does when youre resting.

    Exercise is an important part of disease prevention and that includes cancer prevention, too. But not all exercise is created equal. Its essential that some of your exercise make your heart beat faster than it does when youre resting.

    Getting your heart to beat faster trains your body to move oxygen and blood to your muscles more efficiently, helps you burn more calories and lowers your cholesterol. All of this can help you stay healthy and lower your cancer risk.

    According to the American Institute for Cancer Research, 150 minutes of moderate physical activity or 75 minutes of vigorous exercise each week can help lower your cancer risk. Its the vigorous exercises that can help you get your heart rate up.

    How to measure your heart rate

    So, how do you determine your heart rate? One of the easiest ways to measure your heart rate is with a monitor, says Whittney Thoman, exercise physiologist at MD Andersons Cancer Prevention Center. This is typically a watch or a strap that goes around your arm or chest that syncs with a watch or another device. Many wearable fitness trackers now include heart rate monitors.

    Understanding your heart rate

    Now that you know how to measure your heart rate, you can determine:

    Check your pulse or your heart rate monitor while youre resting and then again while youre exercising to compare your resting heart rate to your active heart rate.

    Heart Rate Increase Any Side Effect

    Why Does Your Heart Rate Increase When You Exercise ...

    It is obvious that during exercise your heart pumps blood faster to the muscle and other parts of the body thereby increasing the heart rate. But the question is, is there any negative effect of the increase in the heart rate?

    So far, there is no scientifically proven side effect of an increase in the heart rate during exercise but there is a maximum heart rate you should not exceed. Your maximum heart rate is the highest rate your cardiovascular or heart can pump during exercise.

    This depends on the intensity of the exercise you engaged in. If you engaged in high-intensity exercise your heart rate will be very high while if you engaged in low-intensity exercise your heart rate will not be as fast as in the case of high-intensity exercise.

    The best way to measure your maximum heart rate during exercise is to know your limit. Dont exercise beyond your physical limit. Doing so will definitely push your heart rate beyond the normal limit.

    Another way to know what your heart rate will be under a high-intensity exercise is to subtract your age from 220. This means that if you are a 40-year-old man, the value of your heart rate will be calculated by subtracting 40 from 220.

    This entails that for a 40-year-old man, the heartbeat will be 180 times per minute during exercise.

    With all these in mind, it is obvious that if you are exercising within your limit, then there is no any side effect as to why heart rate increases during exercise

    Hr Increment Between 40 And 100% Of Maximal Workload Cvd Mortality And Other Exercise Test

    The associations of HR40100 with mortality were compared also with those of VO2max, resting HR, maximal HR, HR reserve, and systolic blood pressure response. All variables were considered as continuous variables, and relative risks were calculated for 1 SD increment. HR40100 significantly predicted mortality after adjustment for known risk factors . When entered into the same model, other exercise test variables had weaker associations with CVD and CHD mortality than HR40100 but VO2max was a stronger predictor of all-cause death than HR40100 . When HR40100 and each of the other exercise test variables were entered into the fully adjusted model using stepwise method, HR40100 remained in the model for CVD and CHD mortality, whereas other exercise test variables did not. In the corresponding model for all-cause mortality, both VO2max and HR40100 were included in the model but VO2max was a stronger predictor than HR40100 .

    The best cut-off point of HR40100 for predicting CVD mortality was 43b.p.m., and 272 subjects had low HR40100 . When HR40100 was entered as a dichotomous variable into a Cox model, the strongest predictor of CVD death was smoking followed by a low HR40100 , myocardial ischaemia during exercise , high systolic blood pressure at rest , high age , and CVD history . The strongest predictor of CHD death was a low HR40100 followed by myocardial ischaemia during exercise and smoking .

    Effects Of Exercise On Blood Pressure

    Aerobic activities such as swimming, cycling, and running put additional demands on your cardiovascular system. Your muscles need more oxygen than they do when youre at rest, so you have to breathe more quickly.

    Your heart starts to pump harder and faster to circulate blood to deliver oxygen to your muscles. As a result, systolic blood pressure rises.

    Its normal for systolic blood pressure to rise to between 160 and 220 mm Hg during exercise. Unless youve cleared it with your doctor, stop exercising if your systolic blood pressure surpasses 200 mm Hg. Beyond 220 mm Hg, your risk of a heart problem increases.

    Different factors can influence how your cardiovascular system responds to exercise. Some of these factors include diet, medical conditions, and medications.

    For instance, exercise hypertension is a condition that causes an extreme spike in blood pressure during physical activity. People with exercise hypertension can experience spikes in systolic blood pressure up to 250 mm Hg during exercise.

    In general, your blood pressure should return to normal within several hours of a workout. Even then, you might notice that your blood pressure doesnt return to exactly what it was before exercise. Thats because its normal for blood pressure to drop slightly within a few hours of exercise.

    The Importance Of Heart Rate When Exercising

    When you were a child, the importance of exercise was probably stressed by your parents and teachers. Playing, running and other activities made you feel good. As youve developed into an adult, its harder to find time for exercise. Its time to prioritize exercise in your life because its effects on your heart are numerous and extremely important. In fact, your heart rate is a measurement that should always be tested as you try new and exciting exercises.

    How To Find Your Target Heart Rate

    What Is A Healthy Heart Rate – What Affects Heart Rate – What Is Maximum Heart Rate

    First, it helps to know your resting heart rate, Martin says. Find your pulse . Then count the number of beats in a minutethats your resting heart rate. The average resting heart rate is between 60 and 100, he says. The more fit you are, the lower your resting heart rate; for very fit people, its in the range of 40 to 50 beats per minute.

    Target heart rate is generally expressed as a percentage of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute. At a 50 percent exertion level, your target would be 50 percent of that maximum, or 85 beats per minute. At an 85 percent level of exertion, your target would be 145 beats per minute. Therefore, the target heart rate that a 50-year-old would want to aim for during exercise is 85 to 145 beats per minute.

    But theres an easier way to figure it out if you want to skip the math: Wear a fitness tracking device, or exercise on a treadmill or other machine that calculates target heart rate for you, Blaha suggests.

    What Should I Do If My Pulse Is High

    Ways to reduce sudden changes in heart rate include: practicing deep or guided breathing techniques, such as box breathing. relaxing and trying to remain calm. going for a walk, ideally away from an urban environment. having a warm, relaxing bath or shower. practice stretching and relaxation exercises, such as yoga.

    Physiological Interpretation Of Hrv

    Interpretation of HRV as reflecting certain aspects of cardiac autonomic activity is complicated by the fact that rather than being a direct measure of autonomic nerve activity, HRV quantifies the modulation of the end-organ response, i.e., HR. HR is under the dual control of direct sympathetic and parasympathetic innervation at the sino-atrial node, but is also influenced by sympatho-adrenal activation and non-autonomic effects such as mechanical/hemodynamic influences and local reflexes . Furthermore, complex non-linear pre-junctional and post-junctional parasympathetic-sympathetic interactions have been reported , whereby activity of one branch can in some instances augment and in other instances attenuate the activity and/or effect of the other branch. It is therefore critical to appreciate that HRV is an indirect indicator of cardiac autonomic modulation.

    Interpretation of HRV measures associated with respiratory sinus arrhythmia

    Interpretation of other HRV measures

    Measures of overall variability are considered to be influenced by both parasympathetic as well as sympathetic cardiac activity, although these measures tend to be associated with cPNA-HRV measures , suggesting that parasympathetic activity is the primary influence. Although HF-nu has sometimes been employed as a cPNA-HRV index , the response of this measure during exercise is not consistent with a decrease in cardiac parasympathetic activity .
