How Do I Take My Heart Rate

What Happens to your Heart when you Exercise – The Human Body – A User’s Guide

There are a few places on your body where itâs easier to take your pulse:

  • The insides of your wrists
  • The insides of your elbows
  • The sides of your neck
  • The tops of your feet

Put the tips of your index and middle fingers on your skin. Press lightly until you feel theÂ;bloodÂ;pulsing beneath your fingers. You may need to move your fingers around until you feel it.

Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate per minute

Exercise And Your Heart

Your heart is a muscle and just like the other muscles in your body, it gets stronger with exercise. Kaiser Permanente explains that when your heart gets stronger, it pushes out more blood with every beat which means it doesn’t have to work as hard to circulate adequate oxygen and nutrients when you exercise. So your heart rate will still rise with exercise, but it won’t have to rise as much.

Regular exercise helps the rest of your circulatory system get more efficient too. This includes greater ability to utilize oxygen, better blood flow in small arteries around your heart and an improved cholesterol profile.


As Kaiser Permanente notes, if you haven’t exercised in a long time or have a history of high blood pressure, stroke, dizziness, heart disease or exercise-related pain, you should talk to your doctor before working out.

Your resting heart rate can provide a useful glimpse into your heart health. Count your pulse for 60 seconds, after a good night’s sleep and before you get out of bed. The result is your resting heart rate.

As the American Heart Association notes, for most people who are sitting or lying down calm, relaxed and not ill a resting heart rate of 60 to 100 beats per minute is normal. Your resting heart rate might be lower if you take certain drugs, such as beta blockers. Athletic people may also have lower resting heart rates, down to about 40 bpm, because their entire circulatory system works more efficiently.


What Are The Symptoms Of Sudden Increase In Heart Rate

When the heart beats too quickly, it is not able to effectively pump blood to the other organs of your body. This may deprive the tissues and organs of your body of oxygen and may result in the following symptoms and signs related to tachycardia:

  • Lightheadedness
  • Heart palpitations, irregular, uncomfortable or racing heartbeat or flopping sensation in chest
  • Fainting or syncope

In some individuals,;tachycardia may produce no symptoms and signs and the condition is discovered when a physical exam is conducted or during an electrocardiogram .

When to Visit Your Physician?

Symptoms of tachycardia and increased heart rate can be caused by numerous medical conditions. Its imperative to get accurate and prompt diagnosis of the condition and appropriate treatment. You should visit your physician if either your kid or you develop any symptoms of tachycardia.

If you develop a fainting episode, have difficulty in breathing or develop chest pain that lasts longer than few minutes, it is imperative to get immediate emergency medical care or you should call your local medical emergency number or 911. You should seek immediate emergency care if anyone else is having these symptoms.


The severity of complications of sudden increase in heart rate;varies, depending on several factors including the kind of tachycardia, the duration and rate of tachycardia and presence of other problems of heart. Some of the possible complications are:

The resting heart rate of most normal, healthy adults is 60 to 100 beats per minute. Your heart rate should increase as your body’s demand for oxygen rises during exercise — but not everyone’s heart responds the same. Various factors can result in an abnormally slow pulse in some people. A low heart rate can be caused by certain medications or may simply indicate a strong heart muscle that doesn’t need to contract as frequently. Unfortunately, it can also signal a health condition. Until a doctor has determined the cause, a low pulse during exercise should be taken seriously.

How Does Cardiovascular Exercise Affect Your Heart

Is it normal to have a 165 heart rate while exercising ...

When performing cardio, blood flow is directed toward working muscles and away from areas that aren’t doing much . There is increased blood flow, and blood volume returning to the heart.

As the heart registers a larger blood volume, over time the left ventricle adapts and enlarges. This larger cavity can hold more blood, and ejects more blood per beat, even at rest.

Over time, with chronic cardio training, our resting heart rate drops because each beat delivers a bigger burst of blood, and fewer beats are needed. This takes work off your heart and is why cardio exercise is recommended for heart health.

However, cardiovascular exercise can also produce stress. If we get into over-training, we may hit a point where we are drowning in cortisol. This eventually leads to immune-suppression and fat gain around the abdomen and face.

People who spend a significant part of their day in stress, who have poor digestion or other sources of physiological stress, should not further their stress levels by overtraining. Always think of your goals, moderate your exercise if necessary, and work to reduce your stress levels.

How Do I Check My Heart Rate

Now that we’ve reviewed why does heart rate increase during exercise, let’s take a closer look at your heart rate.

The easiest way to find your heart rate is to use a heart rate monitor. There are many good ones on the market. Some have bands that go around your chest. Those are usually slightly more accurate. Others just use a watch. It’s a good idea to wear it both while you exercise and when you want to find your resting heart rate.

If you don’t have a heart rate monitor, you can find your heart rate by holding your finger lightly over your pulse and counting the beats for 10 seconds. Then multiply that number by six to get your beats per minute.

What Is A Normal Heart Rate

A normal resting heart rate is usually between 60 and 100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults.

The best time to measure your resting heart rate is just after you wake up in the morning, before you start moving around or have any caffeine.

The Heart’s Response To Exercise

Two of the key functions of the cardiovascular system are to:

1. Transport nutrients, hormones, gases and waste to and from our cells.

2.; Regulate our body temperature and maintain our bodies fluid balance.

When we exercise a greater demand is placed on these functions as working muscles require more oxygen and nutrients than normal, they produce more waste products and generate more heat.;

The degree of the cardiovascular response is determined by the demands placed on it by the training stimulus, the greater the demand the greater the response.; The cardiovascular system is essentially made up of two parts – the heart and the blood vessels .; On the this page we’ll focus our attention on the heart’s responses to exercise.

How Fast Your Heart Rate Should Come Down After Exercise

How to Re-Condition Your Body Through Exercise : How Do I Exercise to Lower Heart Rate?

When you ask the question, “Why does heart rate increase during exercise,” you also have to ask how quickly your heart rate should come back down afterward.

As a general rule, the faster your heart rate recovers back down to normal after exercise, the better shape you’re in overall. That’s why exercise stress tests measure your recovery time.

In the first minute after you stop exercising, your heart rate drops the most sharply. After that first minute, your heart will slow by around 20 beats per minute until you recover. Dropping at less than 12 beats per minute is considered abnormal.

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.

What Is An Average Resting Heart Rate By Age

When you are resting -;whether sitting or lying down -;you can check your resting heart rate. Provided that you have not smoked, consumed coffee, or exercised vigorously an hour before. Activities such as smoking, having coffee, loud noises, and vigorous physical activity make your heart beat faster for a while, and so you might not get your exact resting heart rate. And hence this may interfere with the correct heart rate.

Average resting heart rate by age:

Children : 70-100 beats per minute

Adults :; 60-100 beats per minute

When Heart Rate Or Rhythm Changes Are More Serious

Irregular heartbeats change the amount of blood that flows to the lungs and other parts of the body. The amount of blood that the heart pumps may be decreased when the heart pumps too slow or too fast.

Changes such as atrial fibrillation that start in the upper chambers of the heart can be serious, because they increase your risk of forming blood clots in your heart. This in turn can increase your risk for having a stroke or a blood clot in your lungs . People who have heart disease, heart failure, or a history of heart attack should be more concerned with any changes in their usual heart rhythm or rate.

Fast heart rhythms that begin in the lower chambers of the heart are called ventricular arrhythmias. They include ventricular tachycardia and ventricular fibrillation. These types of heart rhythms make it hard for the heart to pump enough blood to the brain or the rest of the body and can be life-threatening. Ventricular arrhythmias may be caused by heart disease such as heart valve problems, impaired blood flow to the heart muscle , a weakened heart muscle , or heart failure.

Symptoms of ventricular tachycardia include palpitations, feeling dizzy or light-headed, shortness of breath, chest pain or pressure, and fainting or near-fainting. Ventricular fibrillation may cause fainting within seconds and causes death if not treated. Emergency medical treatment may include medicines and electrical shock .

Check your symptoms to decide if and when you should see a doctor.

How Do I Calculate My Maximum Heart Rate

How To: Easily Find Your Target Heart Rate for Exercise ...

That is why it is easier to say that a safe upper limit is 60% to 90% of your maximum heart rate rather than us trying to provide you with a specific number. If you want a general idea of what your maximum exercise heart rate should be, then you take 220 and subtract your age.

That is the maximum rate your heart should beat while exercising. If you are exceeding that amount, then you are working too hard and need to back off until your rate is 60% to 90% of that level.

When it comes to exercising, you want your heart rate to go up. The goal is not to keep your heart rate down, something that many people dont understand. You want your resting heart rate to be low, not your exercising heart rate.

You really want your heart rate to be elevated and if you arent achieving an increase of at least 50% of your maximum heart rate, then you arent benefiting like you should from your exercises.

As you get into better shape, you want to try to achieve 90% of your maximum heart rate to get the most benefit from your exercises.

Preparing For Your Appointment

To prepare for your appointment, see the topic Making the Most of Your Appointment.

You can help your doctor diagnose and treat your condition by being prepared to answer the following questions:

  • Do you have a history of problems with your heart rate or rhythm? If so:
  • Did you see a doctor?
  • What was the diagnosis?
  • What tests were done?
  • How was it treated?
  • When did you first notice the change in your heart rate or irregular rhythm? What were you doing when it started? Were you walking, standing, sitting, or lying down?
  • Is the change in heart rate or irregular rhythm related to activity, or does it happen when you are resting?
  • How often does the change in heart rate or irregular rhythm occur? How long does it last?
  • Is the change in heart rate or irregular rhythm related to eating?
  • What does the change in heart rate or irregular rhythm feel like?
  • Did you have other symptoms with the change in heart rate or irregular rhythm? What were the other symptoms?
  • What have you tried at home to relieve the change in heart rate or irregular rhythm?
  • Do you have any health risks?
  • If you have kept a record of your heart rate or rhythm changes, be sure to discuss this with your doctor.

    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:

    Can You Change Your Resting Heart Rate

    If you run or do other moderate to vigorous physical activity regularly, you can lower your resting heart rate. Thats because exercise strengthens the heart muscle, allowing it to pump a higher volume of blood with each heartbeat. As a result, more oxygen gets delivered to the muscles, so the heart doesnt need to beat as many times as it would in someone who is less fit.

    As people age, the resting heart rate stays about the same unless they are taking medicines that slow heart rate, such as beta blockers or calcium channel blockers.

    To determine your resting heart rate, try taking your pulse when you wake up a few days a week over the course of several weeks. With your index and middle fingers, press lightly on the opposite wrist, just below the fat pad of your thumb. Or press gently on the side of your neck, just below your jawbone. Count the number of beats over a period of 30 seconds. Double that number to get your heart rate in beats per minute.

    A resting heart rate that is too low , or one that is 100 or higher, could be a sign of trouble and should prompt a call to your doctor.

    Defining Maximum Heart Rate

    Your 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 what’s 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 you’re new to exercise, your heart rate will increase quickly with less exercise.
