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

When you exercise, your heart and breathing rates increase, delivering greater quantities of oxygen from the lungs to the blood, then to exercising muscles. Determining an optimal heart rate for exercise depends on your exercise goal, age, and current fitness level.

If Youre In The Middle Of A Race

One of the keys to performing well is getting the most out of your physical ability.

Far too often Ive had a runner tell me he or she was racing along just fine and then boom, out of nowhere they needed to slow way down, Cane says. It might have felt like it came out of nowhere, but in reality, it didnt.

More often than not, the difference between a successful race and a disappointing one comes down to having the awareness to make minor adjustments sooner rather than major adjustments later.

In some cases, an athlete can recognize that their effort is too hard and can back off accordingly.

Oftentimes, by the time your brain has caught on, your body has been writing checks it cant cash for quite a while already, Cane says.

Determining an appropriate heart rate for the event at hand is a great way to help determine the appropriate intensity. If you see your heart rate drifting past where it should be, you can and should adjust, Cane says.

Ideally, Cane adds, that adjustment is a subtle one, and the combination of tuning into the bodys cues and the data from your heart rate monitor can help you know when to back off a little. That scenario is preferable to having to slow to a walk.

Of course, in a race setting, at a certain point you should just race and react and not worry about going too fast, but in the earlier stages, its important not to let your ambition get the best of you.

What Happens When Your Running Heart Rate Gets Too High For Too Long

Take a marathon training schedule, for example. A marathon training plan has a lot of easy, aerobic runs, because the act of running a marathon is primarily aerobic, Lakritz says. Your body has to become really efficient at burning fat for energy so it can last a long time.

Over time, the pace at which you can do this will improve you can run faster at the same heart rate as you get in shape. But, if you consistently run your easy runs at 75% of your max heart rate, you wont train this system of your body.

Youll probably get better at shorter distance races because youre training the lactic threshold system, which helps you run faster for a shorter period of time, Lakritz explains. But by always running at this pace, your body wont be able to recover enough to properly train the lactic threshold system, either.

Eventually, running at a heart rate thats too high for the purpose of your training will lead to a plateau in race times, burnout, or injury.

Your body will already be tired, so your heart rate will actually be higher at slower running paces. According to your heart rate, you might be within your lactic threshold range at a 6-minute mile pace if youre tired from running too fast the previous day. But if you were fully recovered from the previous day, you might be able to run a 5:45 pace at the same heart rate range.

While heart rate training is a great tool to ensure youre training in the appropriate zones, the numbers dont lie.

What Should Our Maximum Heart Rate Be During Exercise

You have your runners on, your FitBit is charged, but now what?

When you exercise, your heart and breathing rates increase, delivering greater quantities of oxygen from the lungs to the blood, then to exercising muscles.

Determining an optimal heart rate for exercise depends on your exercise goal, age and current fitness level.

Heart rate and exercise intensity share a direct, linear relationship: the more intense the exercise, the higher the heart rate.

When you exercise at the highest possible intensity, your heart will reach maximal heart rate , the fastest rate it is capable of beating.

But exercising at a maximal heart rate for every exercise session will not produce efficient fitness results. These high intensities can rarely be sustained, negating the potential benefit of the exercise.

Exercise Makes Your Heart More Efficient

Is it better to exercise at 90% of your maximum heart rate ...

Typical resting heart rate can vary quite substantially between people and even within an individual. Around 60-80 beats per minute for adults is common.

Improving your aerobic fitness reduces your resting heart rate, as the heart becomes more efficient with each beat. An athletes resting heart rate, for instance, is typically around 40 BPM.

In fact, evidence suggests that long-term exercise training increases the size of the heart, specifically the left ventricle, a phenomenon known as Athletes Heart. A bigger heart means more blood can be pumped with each beat, and fewer beats per minute are required to maintain blood flow around the body. This is a beneficial physiological adaptation allowing athletes to exercise at higher intensities for longer.

Why Does My Heart Rate Go So High When I Exercise

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.

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 To Calculate Your Maximal Heart Rate

Ideas on how to recover when your heart rate gets too high.

There is substantial variation in HRmax. The only true method of determining HRmax is to conduct a maximal exercise test. But HRmax can be estimated using formulas based on age.

The authors of a 2001 study proposed the following revised equation for estimating maximal heart rate:

HRMax = 208

This means a 45-year-old would have a predicted HRmax of 177 BPM.

Indeed, our genetics can influence actual maximal heart rates from their predicted value. However, HRmax is not a major determinant of exercise or athletic performance. Far more important is our physiological efficiency.

When assessing heart rate, its also important to take into account the effects of emotions such as excitement or fear, stimulants like caffeine, and circulating hormones like adrenaline, all of which can increase heart rate.

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.

How To Tell If Your Running Heart Rate Is Too High And Then What

Originally published April 12, 2018 9:15 am, updated September 28, 2020

Its Track Tuesday, and youre up with the sun to meet your crew for an intense 12x400m workout. After a proper warm-up, you take off, crushing the first interval. Then the second. Then the third.

Going out too eager, too hard, and too fast is common. But sometimes, the problem isnt just the pace, and its definitely not your legs its your heart rate. While what goes up must eventually come down, there are warning signs that youre working too hard and thats not always a good thing.

Question: What Happens To Heart Rate During Exercise

  • Posted On:

During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.

Understanding Your Target Heart Rate

When Your Heart Rate Gets Too High During HIIT, This Is ...

Nearly all exercise is good. But to be sure youre getting the most fromyour workout yet staying at a level thats safe for you, you can monitorhow hard your heart is working.

Aiming for whats called a target heart rate can help you do this, says Johns Hopkins cardiologist Seth Martin, M.D., M.P.H. Think of it as the sweet spot between not exercising hard enough and overexerting.

Knowing Your Resting And Maximum Heart Rates

Your heart rate tells you how hard you are working. But the number isnt terribly helpful without context. You need a scale with your resting heart rate at one end and your maximum heart rate at the other end.

A normal resting heart rate is between 60 and 100 beats per minute . Many athletes have an RHR lower than 60 because their heart is stronger and more efficient.

To get your true RHR, take it before you get up in the morning. Wearing your heart rate monitor while resting is an easy way to find yours.

You can also take your RHR manually. Heres how:

  • Place your first two fingers inside your wrist and find your pulse
  • Using a stopwatch or the second hand of a clock, count the beats for 30 seconds
  • Multiply by two to find your RHR

The standard formula for finding your MHR is 220 minus your age. Using this formula, a 50-year-olds maximum heart rate would be 170.

However, a 2018 study published in Frontiers in Physiology found that this formula often overestimates for women and underestimates for men. For that reason, its important to remember that 220 minus your age is a general guide, not an exact number.

What Heart Rate Is Too High

Generally, for adults, a heart rate of more than 100 beats per minute is considered as high.

Your heart rate usually rises when you walk fast, run, or do any strenuous physical activities.

Maximum heart rate and Target Heart Rate

Before doing any vigorous exercise, you should know your maximum heart rate and target heart rate, both of which vary by age.

Going beyond your maximum heart rate is not healthy for you. Your maximum heart rate depends on your age. This is how you can calculate it:

  • Subtracting your age from the number 220 will give you your maximum heart rate. Suppose your age is 35 years, your maximum heart rate is 185 beats per minute. If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you.
  • Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.
  • Your target heart rate helps you to know if you are exercising at the right intensity.
  • It is always better to consult your doctor before starting any vigorous exercise. This is especially important if you have diabetes, heart disease, or you are a smoker. Your doctor might advise you to lower your target heart rate by 50 percent or more.

Given below are the table showing the target heart rate zone and maximum heart rate as per age.

How To Measure Heart Rate

Measuring your heart rate is easy to do if you follow some simple steps. The easiest place to measure your heart rate is on your wrist, just below the base of the thumb. Place your index and middle fingers between the bone and tendon at the base of your thumb. Once you feel your pulse, count the number of beats you feel in 15 seconds. Once youve counted how many pulses, youll multiply that number by four. This gives you the total amount of times your heart beats in one minute. For example, if your heart beats 18 times in 15 seconds, your heart rate is 72 beats per minute.

Its important to measure your heart rate when youre in a relaxed state. If you take your pulse after any strenuous activity, you wont get an accurate reading. You should wait for one to two hours after exercising to take your resting heart rate, and an hour after consuming caffeine, according to Harvard Health.

How To Lower Your Resting Heart Rate

Cardiovascular Drift Explained – Heart Rate INCREASE During a Steady Run

How can you dial down a resting heart rate? Lifestyle changes can boost heart health and lower your pulse.

1. Get moving

Exercise is the number one way to lower resting heart rate, says Dr. Singh. The most common cause of a high resting heart rate is a sedentary lifestyle, one where you spend a lot of time not moving.

And being in poor shape can increase the risk of other problems, including obesity, high blood pressure and diabetes. To give your heart a healthy workout, the American Heart Association recommends at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous activity.

The more you exercise, the stronger your heart becomes. Since its pumping more blood with each beat, it wont need to pump as hard, which will lower your heart rate, she says.

2. Manage stress

Anxiety and stress can elevate the heart rate, too. To help bring it down, try to bring calm to your day, Dr. Singh says. Practice mindfulness, try to meditate or do breathing exercises.

3. Avoid caffeine and nicotine

Stimulants like caffeine and cigarettes can drive your heart rate up, Dr. Singh says. Cutting back may help lower your resting heart rate.

4. Maintain a healthy weight

The more weight you carry, the harder your body has to work to move blood through the body especially if you dont have a lot of muscle mass, Dr. Singh says. Losing weight can help bring down your heart rate.

5. Stay hydrated

6. Sleep well

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.
