Most of us are pretty much already aware that exercise is good for the body, but when you understand how exercise changes the body, it makes getting off your bed and into the gym much easier. The body is a complex machine, and a lot of changes typically take place when you start working out.
When you exercise, one tends to breathe faster than usual, and this has prompted so many people to ask the question: How is blood flow related to lung function during exercise? Well, the answer to this question is easy but in requires a better comprehension of the changes that occur in the body when we exercise.Blood Flow Related To Lung Function During ExerciseHow Is Blood Flow Related To Lung Function During Exercise?Importance of Breathing Properly During ExerciseHelps in Maintaining PostureImproves PerformanceImproves Fat LossNasal Breathing vs. Mouth BreathingNasal Breathing.Mouth Breathing. Conclusion
As mentioned earlier, a lot happens to your body during exercise, and the very first thing you will probably notice is that you are out of breath and your pulse is high. However disconcerting it may feel, it is a normal body response. If that is the case, then how is blood flow related to lung function during exercise?
When you exercise, the blood vessels are dilated so as to increase the volume of oxygen carried in the blood, and as a result, the lungs work harder to satisfy the body’s oxygen demands.
Also, the blood circulation volume increases when you exercise, making your body more efficient; hence the lungs must work just as hard to maintain the body’s efficiency level.
It is not a secret that you have to breathe properly when performing aerobic activities, like running or swimming, or other types of exercise such as bodyweight training or strength training. Besides ensuring that your connective tissues and workout muscles get sufficient oxygen, here are other benefits you will accrue from following the right breathing pattern.
When you inhale during exercise, the chest expands, and as a result, it aids in keeping your back straight. This is crucial when exercising because a majority of the exercises we perform require that our back be in line.
Besides, the right workout posture provides safety and ensures that you work your target muscles properly.
When you follow the right breathing pattern during exercise, you take in oxygen that’s distributed throughout your body to provide your muscles the power to push on. The more power your muscles have, the more improvements you get in your overall body performance.
Also, breathing properly during exercise means there will be more oxygen for your body to use for other functions.
The body requires water and oxygen to convert body fat into energy. The more oxygen you take in – through proper breathing, the more your body gets rid of fat, toxins and stored water resulting in weight loss.
Breathing in properly fuels this process and therefore allows you to shed the fats faster and more efficiently.
Poor breathing slows down your metabolism since the body’s trying to cling onto the resources it already has, which in turn produces fat. With improved breathing, however, you can reverse this process.
There’s always the tendency for people, whether adults or children, to breathe through the mouth instead of the nose. Whether you’re going about your daily life, sleeping or exercising, it’s preferable to breathe through the nose than through the mouth.
Mouth breathing causes the brain to perceive that carbon dioxide is leaving the body too fast and as a result, it stimulates the production of mucus in an attempt to slow the breathing.
Breathing through the nose is more efficient that mouth breathing with regard to supplying oxygen to the body. When doing cardiovascular exercise, it is advisable to inhale and exhale through the nose to facilitate filtering and warming of the inhaled air.
Breathing through the nose is way healthier than mouth breathing for some reasons. The lungs take oxygen from the air, and most of the oxygen absorption occurs on exhalation. Exhaling through the nose causes higher air pressure and as a result, a slower exhalation which gives the lungs more time to extract large volumes of oxygen.
This is common in people whose nasal passages are restricted or blocked. For instance, a small nostril size can cause one to breathe primarily through the mouth. Mouth breathing is greatly discouraged because it is inefficient and can result in hyperventilation, which worsens the symptoms of asthma.
When you exercise, the lungs and blood circulatory system respond differently to satisfy the body’s demands for more energy. The most commonly felt response is a rapid heartbeat and a more powerful lung function to deliver sufficient oxygen to the body muscles.
Besides facilitating optimal oxygen intake, here are some other benefits of breathing properly during exercise:Improves performanceHelps in maintaining postureImproves the body’s fat burning capabilities

What is cardiorespiratory exercise? How might regular cardiorespiratory exercise affect hypertension? Cardiorespiratory exercise, also known as cardiovascular fitness involves body movements that increase the heart rate for better oxygen transportation and consumption by the body tissues.
Being a crucial aspect of almost any exercise program, cardio not only aids you in maintaining or losing weight, but also lets you build endurance so that you remain active for longer periods of time. Besides, regular cardiorespiratory exercise helps improve your cardiorespiratory fitness.Cardiorespiratory Exercise Affect Hypertension? IntroductionHow Might Regular Cardiorespiratory Exercise Affect Hypertension?What are The Benefits of Cardiorespiratory Exercise?Improved Heart HealthIncreased MetabolismImproved Recovery AbilityWhat Cardiorespiratory Endurance Exercises can You Perform?Walking SwimmingCyclingConclusion
About one in three adults suffer from hypertension, but a majority of them do not realize. In most cases, hypertension is referred to as a silent killer because it usually has no signs and it can result in life-threatening conditions such as stroke and heart attack. Many people are always asking, how might regular cardiorespiratory exercise affect hypertension?
The answer is that high blood pressure may be reduced almost immediately following and for about 24 hours after cardiorespiratory exercise. This is a telltale indicator that cardio plays a critical role in the mitigation and reduction of high blood pressure.
For some people, cardio is a dreaded word while for others, it is a passion they cannot get enough of. However you choose to view it, the truth is that cardiorespiratory exercise is one of the most important components that shouldn’t be omitted in any fitness plan.
Many people doing cardio use it as a way to shed of the excess fat and calories since a lot of body movement is involved. However, it should be known that weight loss should not be the only reason to do cardio. There are many other benefits that you can reap from regular cardiorespiratory exercise as highlighted below.
One great benefit of cardio is improved heart health. Just like other body muscles, the heart requires frequent working and exercise for it to remain strong. Failure to exercise the heart will cause it to weaken over time which can result in an array of adverse health effects.
Getting the heart to pump faster regularly will help keep it healthy and in good shape. In addition, cardiorespiratory activity forces the lungs, heart and circulatory system to work hard as to deliver oxygen-rich blood to the body muscles.
Another great reason why cardio should be part of your fitness program is because of its effect on your body metabolism. Apart from increasing your heart rate alone, cardio also plays a crucial role in increasing the rate of many other body processes.
From a medical perspective, the greater the intensity of your cardio session is, the more noticeable increase you shall witness in terms of your metabolic rate. Increased body metabolism translated into an easy time maintaining your body weight.
Some forms of cardiorespiratory exercise, usually the low-intensity and moderately paced forms, reduce your recovery time after exercise. If you’ve been hitting the gym hard for almost an hour, a light jog or walking on the treadmill will help in getting rid of all waste products that were created by the body during your intense gym session.
Cardio not only aids in reducing muscle soreness but also helps in the delivery of oxygen-rich blood to the body muscles for an improved muscle repair and rebuilding process
Medical experts define cardiorespiratory endurance as the ability of the body to deliver oxygen and nutrients to the body tissues and get rid of waste products over a period of time. Improving your cardiorespiratory endurance by performing aerobic exercises can aid in weight maintenance, weight control and minimize the risk of heart disease.
Here are some exercises that can improve your cardiorespiratory endurance.
Walking is a pretty easy aerobic exercise that many people can do because it can be done either indoors or outdoors and is completely free. Regular walking can minimize your risk of suffering from type 2 diabetes and improve your sense of well-being.
It is always advisable to have a comfortable pair of aerobic exercise, plenty of drinking water and maintain a moderate pace when walking.
Research indicates that swimming is the third most popular sports activity in the US. There are individuals who can exercise for a long period of time in water without experiencing muscle or joint pain.
Swimming is an excellent way to improve your cardiorespiratory endurance for better heart health and overall body function.
Besides being an environmentally friendly way to travel, cycling is a great way to boot your cardiorespiratory fitness. Better yet, cycling is a low-risk, non-weight bearing activity that helps you work your body muscles perfectly.
A healthy heart is the key to a healthy and well-functioning body. Better heart health can be achieved by incorporating cardiorespiratory exercises in your fitness program. Besides weight loss, some other benefits of cardio are:Increased body metabolismImproved heart healthImproved recovery ability
It’s my hope that you enjoyed this post and if you have any queries or comments, drop them down below. I would love to hear what you have to say.
Blood pressure (BP) is the amount of force exerted against the inner walls of the arteries and blood vessels. It is maintained by the elasticity of the diameter of the vessels and arterial walls, and also by the thickness in consistency and volume of the blood.
When the arteries become narrow and constricted, it is then that the blood pressure rises and possible damage to the arteries is expected. The pressure of the blood is a very important factor in keeping the heart and other vital organs healthy and the body in a normal state.
Any abnormalities in the blood pressure affect the entire condition of the body. Blood Pressure readings are always highest in the morning and lowest in the evenings.
We’ll look today at how to check blood pressure any equipment at home although this is not really your best option. We’ll also show you how to make use of monitoring gear for a more accurate result.
Before that, though, we’ll walk you through some of the basics of blood pressure…How To Check Blood Pressure The Fact- Heart Disease in the United States Two Types of Blood Pressure Systolic PressureDiastolic PressureBlood Pressure CategoriesNormal Blood PressureLow Blood Pressure/HypotensionPre-High Blood Pressure/ Pre-HypertensionHigh Blood Pressure/HypertensionExternal ForceInternal ForceSymptoms Of High Blood Pressure / Hypertension InfoGraphic Ways to Check Blood Pressure at HomeBP Monitoring with EquipmentAmbulatory Blood Pressure Monitoring Devices/ABPMAutomatic BP Monitoring EquipmentManual Blood Pressure Monitoring ToolsMonitoring BP without an EquipmentRadial ArteryFemoral ArteryCarotid ArteryWrap UpRecommended Blood Pressure Monitors
(Source: Center Of Disease and Prevention)About 610,000 people die of heart disease in the United States every year–that’s 1 in every 4 deaths.Heart disease is the leading cause of death for both men and women. More than half of the deaths due to heart disease in 2009 were in men.Coronary heart disease (CHD) is the most common type of heart disease, killing over 370,000 people annually.Every year about 735,000 Americans have a heart attack. Of these, 525,000 are a first heart attack and 210,000 happen in people who have already had a heart attack
This is medically defined as the pressure exerted within the arteries while the heart is pumping. It is the first loudest sound that you can hear using a stethoscope.
Systolic pressure is also the top number of the two readings to be written. It is always the higher number.
The normal BP for systolic pressure in adults is less than 120 mmHg.
This is the type of pressure inside the arteries when the heart is in a resting phase in between beats. This is the last loudest sound that you can hear when you check the BP.
Diastolic pressure is the bottom number of the BP reading result and is always the lower number.
The normal reading for diastolic pressure in adults is less than 80 mmHg.
Normal blood pressure is extremely important. When your BP reading is normal, everything is therefore normal. You feel healthy and strong with no body discomfort whatsoever.
This feeling of wellbeing is because there is adequate flow of oxygen to your body. There is no blood flow constriction and the nutrients are being distributed throughout your whole circulatory system.
A normal BP reading in adults is listed as 100/60 to 120/80 mmHg.
For infants, it ranges from 75/50 to 100/70 mmHg.
For children, the normal range is 80/50 to 110/80 mmHg with 95/60 to 140/90 mmHg for teens.
Low blood pressure usually doesn’t pose much of a concern unless it provokes symptoms of dizziness, fainting and weakness. In this case, doctors prescribe iron supplements and a more iron-rich food intake. For some people, this condition is still manageable and doesn’t hinder their daily lives.
A blood pressure of 90/60 and lower is considered as hypotension.
Blood pressure of 80/50 in adults can even cause a stroke in some patients and may lead to a serious condition such as coma if not treated right away. This is actually an emergency case.
This category comes with a reading of 120/80 to 139/89.
This stage is not yet considered as full-blown hypertension but it’s almost there. Patients are advised to take a 3-day rest from work or school, to eat sensibly and drink lots of water. A glass of diluted but real pineapple juice, lemon or orange also helps to lower the blood pressure back within its normal range.
This is when the blood pressure recordings are in the 140/90 bracket and higher.
There are instances when a patient’s blood pressure rises whenever they are checked by a doctor but when they are at home it is normal, even if they are tired. This is what health professionals term as White Coat Syndrome. Patients become stressed when they see a doctor. This in turns causes their blood pressure to rise.
This is the reason doctors recommend that these patients buy a Blood Pressure Monitoring device to record their blood pressure at home. It’s essential to determine if the person is really hypertensive or not before prescribing high blood medications. High blood pressure is a serious, life threatening disease.You may read: How Might Regular Cardiorespiratory Exercise Related to Hypertension.
DO YOU KNOW?
17 May is dedicated to World Hypertension Day.
"The WHD was first inaugurated in May 2005 and has become an annual event ever since. The purpose of the WHD is to promote public awareness of hypertension and to encourage citizens of all countries to prevent and control this silent killer, the modern epidemic."
(Source: International Society of Hypertension)
The doctors usually try to treat the patient with a two-week prescription of high blood drugs, diet and rest. After the two-week period, the patient is withdrawn from medication. If the condition persists without the drugs then the patient will be a candidate for maintenance hypertension drugs.
Important Note: There are some considerations in BP readings when it comes to the weight of the patient. For instance, if the adult patient is underweight, a BP recording of 90/60 is normal and a 120/80 is high.
A slight rise in blood pressure doesn’t always mean that a person is hypertensive. There are many factors to consider and lab tests are carried out to determine what is causing the high blood pressure.
There are two main reasons for a high rise in blood pressure and they are as follows…
This is mainly due to stress and intense emotions like fear, anger, pain, sadness, tiredness and depression. When you are feeling any of these extreme emotions, blood pressure is likely to rise. This is nothing to be scared of since the blood pressure will eventually go down when you have calmed down. Rest and a glass of water is all that’s required.
Important Note: If the BP is still recorded as high after you are calm and rested then you are already hypertensive.
This factor gives cause for concern in both the doctor and the patient.
Blood Pressure rises in this case if the person has any of these issues:Heart diseaseKidney problemsHigh cholesterolHigh sodium and uric acid content in the bloodDiabetesExcessive drinkingSmokingClogging in the arteries
This is called secondary hypertension.
Heredity is also a contributing factor. If one of your parents is hypertensive, even if you live a healthy lifestyle, you may inherit the disease once you hit your 40s or even as early as your 30s.
Age plays a major role too when the person is in their 50s, even without any health issues. This one is called essential hypertension.
Such factors can lead to full-time hypertension with a lifetime of maintenance drugs prescribed to control the blood pressure. In these cases, daily blood pressure monitoring is a must. The patient doesn’t need to go to the doctor’s clinic everyday though. Having a regular blood pressure check at home is sufficient to keep a close eye on things. They will be advised to purchase their own Blood Pressure monitoring equipment. Check our doctors' recommendation.
In line with this, we will tackle below how to monitor blood pressure at home with or without equipment.
Blood pressure is read according to millimeters of mercury or what is termed as mmHg. This is done using monitoring equipment to accurately get the actual blood pressure reading of a patient.
This is carried out to accurately get the actual blood pressure reading of a patient using monitoring equipment known as a sphygmomanometer and stethoscope.
Below are types of blood pressure monitoring devices used to acquire such data…
This is most commonly used if there is a significant disparity between the blood pressure readings acquired at home and at a doctor’s clinic.
It is a small device worn by the patient at home or anywhere he goes. It also shows the blood pressure readings automatically and accurately every thirty minutes even if the patient is asleep. This device is usually given to pregnant women and patients with the so-called White Coat Syndrome discussed above.
ABPM comes with an arm cuff or wrist cuff and should be worn the whole day even while doing chores and exercises.
This is the other name for the digital and electronic blood pressure monitoring devices. They come with a microphone and cuffs that detects the pulsating blood in the arteries.
Just press the start button and the cuffs automatically inflate and it does the monitoring itself. This also has a wrist-monitoring cuff but reports say that the arm cuff takes blood pressure more accurately than this one.
These are the conventional types of blood pressure monitors. They are the ones widely used at the doctor’s clinic or in hospitals. It’s by far the most accurate of all. It comes with an arm cuff, stethoscope, a squeeze bulb and a mercury gauge to measure the blood pressure.
Measuring is done while the cuff is wrapped on the upper arm and the bulb is squeezed while the stethoscope is placed on the skin where the brachial artery is located just below the upper arm.
The first loudest sound or pulse beat you hear from the stethoscope is the systolic pressure and the second or last sound is the diastolic blood pressure reading.
Caution: Monitoring blood pressure at home without Blood Pressure monitoring equipment is never entirely accurate. People who favor this method should also watch out for high blood and low blood symptoms to support the result. This step is taught but not very widely accepted. It is merely to give patients a rough idea of their blood pressure level to avoid any wrong assumptions.
There are a few things to consider if you wish to check your blood pressure at home without monitoring equipment.
Your doctor should be notified you want to do it without a device. Your cardiologist will tell you when and how to do it.
Here are certain methods on how to monitor your blood pressure without any monitoring equipment. You will do it through artery palpation.
First, you have to locate the radial pulse of the other hand with your index and middle fingers. You may use whichever hand suits you. The radial artery is at the wrist at the lower arm. Palpate your wrist to feel the pulse.
Now, when you locate the pulse, feel how strong it is…
If the pulse seems moderate, the systolic measurement is 80 mmHg.
If the pulse seems weak it is about 60 to 70 mmHg.
And, if the pulse is very palpable, you have a systolic measurement higher than 80 mmHg.
This artery is located at the groin.
Feel for a pulse slightly below the groin and above the thigh. A strong pulse means the systolic measurement is about 70 to 80 mmHg.
This is the artery along the voice box inside the neck.
The pulse here is usually very palpable since it is nearer the heart. Press the artery slightly to feel the pulse as to not block the oxygen from getting into the brain.
Getting a strong, palpable pulse means the systolic pressure is 70 to 80 mmHg.
When taking blood pressure without using any medical equipment, you need to know that there is no way the diastolic blood pressure can be measured. It is only the systolic blood pressure measurement that can be checked. Diastolic blood pressure can only be measured using a cuff.
Blood pressure monitoring is highly important, especially to patients with known blood pressure problems.
It is always recommended to consult your doctor and have your Blood Pressure checked professionally.
You should also try to acquire a monitoring device suitable to your budget and needs. As research shows, artery palpation methods are not a very effective step to use. It can help at some point but best not to rely much on doing it often.
We hope that with this simple information, we have supplied you with ample knowledge about blood pressure and methods on how to monitor it.

You’ve probably been fed with tons and tons of information regarding cellular respiration and breathing by your physician, friends, and personal tutor. Cellular respiration is an automatic body function whereas the quality of our breathing patterns is improved with exercise.
Breathing involves exhaling and inhaling air. On the other hand, cellular respiration includes the exhalation, inhalation, and air exchanges that take place in the lungs. If that is the case, then how are breathing and cellular respiration similar? Let’s find out!Breathing and Cellular Respiration Similar? Introduction How Are Breathing and Cellular Respiration Similar? How Does the Respiratory System Respond to Exercise? Oxygen Transport. Respiratory rate. Long-term Response. How Can You Improve Your Respiratory System Health? Maintain a Healthy Weight Stay HydratedAvoid SmokingLearn Yoga Breathing Techniques.Conclusion
The similarity between cellular respiration and breathing is one that people can barely explain; they were probably never serious with their biology. All the same, we are here to get the answers.
The similarity between breathing and cellular respiration is that breathing provides the oxygen molecules required for cellular respiration to take place.
When you breathe in, the oxygen needed for respiration is provided. When you breathe out, carbon dioxide produced by respiration leaves the body. This is a clear indication that these two body processes depend on each other and without either of them, the other cannot take place. For the whole process to begin, glucose and oxygen are required
But since the body does not produce oxygen, it needs to acquire it through breathing. During respiration, body cells receive the energy they need to perform their tasks.
This energy is usually produced by breaking down fuel molecules like fats, carbohydrates, and lipids, through a process called oxidation. Water and carbon dioxide are the two waste products of cellular respiration.
The respiratory system, which consists of a series of body parts including the nasal cavity, diaphragm, and lungs, is responsible for the transportation of oxygen and carbon dioxide to and from the body tissues and muscles. When you exercise, cellular respiration increases to fuel the working muscles.
To meet the increasing demand for oxygen, additional oxygen must be moved through the blood vessels to the working muscles. During exercise, the veins constrict so as to return more blood to the heart. This blood is rich in carbon dioxide released after cellular respiration has occurred in the body muscles and can increase the heart’s total stroke volume by 40 to 50 percent.
With an increased amount of carbon dioxide and oxygen transport, the rate of cellular respiration increases, and so does the speed of breathing. This increase is also attributed by the sympathetic nerves triggering the respiratory muscles to increase the breathing rate.
At rest, the respiratory rate is just about 14 per minute, and it increases to 32 per minute when you exercise.
A long-term response of the respiratory system to exercise involves an array of physiological adaptations. In the long term, these adjustments lead to an increase in an overall efficiency of the respiratory system to collect, transport and deliver sufficient oxygen to the body muscles. Through regular training and exercise, the effectiveness of your respiratory system increases.
The respiratory system is tasked with supplying your blood with sufficient oxygen. The trachea filters the air you breathe, the lungs facilitate absorption of oxygen and breathe out carbon dioxide, and the diaphragm supports healthy breathing. Besides medications, when needed, here are ways to aid in strengthening and improving your respiratory system.
Excess body weight is not only a burden to your legs but also puts more stress on the lungs, and it compresses your respiratory muscles forcing them to work hard to meet the body’s demands for oxygen.
Be sure to stick to a diet that’s easy to follow, nutritionally sound, most importantly, one that helps you maintain your body weight. Whether you choose healthy eating or plethora or aerobic exercises, take it seriously and shed the extra pounds.
Drinking lots of water on a daily basis aids in maintaining a healthy body weight and gives a thin consistency to the mucous lining of your lungs and airways. Dehydration can cause the mucus lining to thicken and get sticky, which may slow down the respiratory process and worst of all, make you more prone to illness.
Smoking damages the lungs and causes deterioration of the respiratory system’s health by inducing cell inflammation, speeding oxidative stress in the respiratory cells and even cell death, potentially leading you to the inevitable path of lung cancer and chronic lung disease. It’s essential that you quick smoking, which does more harm than good to the lungs
If you are a shallow breather, learning yoga breathing techniques can help you breathe more efficiently. Taking long, deep breaths will not only help in better lung function but also give you a sense of calmness.
Besides, some yoga breathing techniques are quite renewing and an excellent form of lung exercise. Over time, it can increase your lung capacity.
Cellular respiration is a critical process in the body’s daily functions, and it supports most of the body’s functions. Good respiratory system health means that the body muscles have sufficient fuel to support all body processes, from the most basic process to the rather complex processes. For better respiratory system health, you need to:Always stay hydratedAvoid smokingMaintain a healthy weight

If you are a gym enthusiast, an athlete or have ever exercised in your life, then you would realize that your heart rate increases when you exercise. Even when you halt your exercise, your heart rate does not return to normal instantly. So why does the heart beat faster when you exercise?
Some people may be worried about it, but truth be told, most of the time it should not be a cause for uproar. The body needs more nutrients and produces more wastes as the muscle activity increases. The body responds to these changes by increasing the speed at which the heart beats.Why Does Your Heart Beat Faster When You Exercise? Why Does Your Heart Beat Faster? Blood Vessel DilationWaste EliminationNeural ControlIncreased Body Metabolism How Does Exercise Affect Your Heart? Cardiovascular ExerciseStrength Training ExerciseIN CONCLUSTION
The body muscles require more oxygen and energy during exercise. The blood vessels supplying the active muscles expand to allow for more blood and nutrient flow to the muscles. As these blood vessels expand, the vessels in the kidneys and stomach constrict.
However, more blood vessels expand than contract, requiring the heart to pump more blood. As a result, a faster pulse is triggered so as to maintain a healthy blood pressure.
Intense exercise causes the body muscles to produce large volumes of waste in the form of carbon dioxide, hydrogen ions, adenosine and lactic acid. The accumulation of these wastes in the body can at times be fatal. For instance, too much lactic acid in the body can lead to acidosis.
Acidosis is usually as a result of pH imbalances in the body organs and leaves you at risk of catching a migraine, lack of appetite and fatigue.
The increased heart rate during exercise produces a faster blood flow rate which allows the blood to sweep these wastes away from the muscles and excrete them through urination, sweating or exhalation.
The body’s sympathetic and parasympathetic nervous systems are responsible for controlling the rate at which your heart beats. Just before an exercise session, the heart rate is normal. As training begins, the sympathetic nervous system triggers your heart to beat faster in response to the body’s demands
In most cases, exercise involves vigorous activity that increases the energy demands for the muscles. Although anaerobic metabolism can produce some energy, most of the muscle’s energy needs are fulfilled by aerobic metabolism which requires oxygen.
Since the bloodstream is responsible for supplying oxygen to the muscles, your heart must pump a large volume of blood to maintain the necessary oxygen supply for the muscles to remain active. For a healthy oxygen supply to the muscles, your heart starts beating forcefully and rapidly, which increases the heartbeat.
Besides, if you’re training on a hot day, the high temperatures coupled with rigorous heart activity will increase the heart rate substantially. This occurs because the heart needs to supply blood to the skin to cool you down. This change will require the heart to beat quicker than usual.
We are well aware that the heart rate increases because the heart needs to deliver more oxygen to the body muscles. But what more will exercise do to your heart?
When you engage in cardiovascular exercises, blood flow is channeled towards the working muscles, away from parts that are not working hard as much (like the digestive tract). The blood volume increases and subsequently, blood flow returning to your heart increases.
When the heart registers a significant amount of blood, the left ventricle starts adapting to the change and increases in capacity. This larger cavity can now hold and pump more blood with a beat, even when you are resting.
Consistent cardiovascular training results in a decrease in the heart rate when resting since every beat delivers a large volume of blood, which is why fewer heartbeats are needed. This relieves the heart a huge burden, which is why cardio exercises are the best for a healthy heart.
Strength training exercises work the heart differently from cardiovascular exercises. In strength training exercises, specific body muscles are always contracting, and as a result, blood vessels flowing through the muscles are pressed and blocked.
This builds up pressure in the circulatory system, requiring the heart to fight hard to push the blood. With time, new blood vessels and capillaries are formed, which facilitates better blood circulation.
A faster heart rate when exercising should not be a cause for alarm because it is just one of the numerous mechanisms the body adopts to meet its oxygen requirements and energy demands. This is just a short term change meant to keep your muscles running as you perform your fitness regime.
