what does an increased pulse rate indicate about the heart rate and flow of blood in someone's body?

it could mean many different things.  it is amazing the effects stress along can have on your body. to be sure and safe i would suggest a ekg, it is the easiest of the many possible test, it basically records you heart rhythm. if there is something, the would indicate so

body needs more oxygen(in blood) to provide energy for the excercise, excitement etc.

increased heart rate. at first your heart started beating faster and requires an increase of blood flow (pale face) and then continues to pump fast even when you stop to work out(red face) until you cool down and return to a normal heart rate.

During exercise, the quantity of blood pumped by the heart increases to match the increased skeletal muscle demand. Heart rate (HR) monitoring is a method commonly used to determine and assess exercise intensity levels. Exercise intensity is a key component of the training response. Therefore, it is important to understand the factors that can influence HR during exercise, so modifications can be made when establishing training heart rate (THR).

What you are describing are known as "orthostatic changes."  We use orthostatic blood pressures and pulse rates in the evaluation of dehydration and moderate blood loss.\n\nAloha

As the heart increase in size, the surface area increase by the square, while the internal volume increases by the cube.\nExample: internal volume = Length * Width * height\n\nAs the internal volume increases the amount of blood pumped per heart beat (stroke volume) increases.\n\nThe actual “strength” of the heart is unchanged. Cardiac myosites are essentially unchanged between different mammal species. \n\nWell trained athletes tend to have a health heart hypertrophy (enlarged heart) and have heart beats in the 40’s-50’s BPM while the average adults range in the 60’s-80’s.\n\nAs an end product of all of this, large animals tend to have slower metabolic rates because while it may be possible for a 6 oz bird to eat its weight in insects a day a large animal like a dog can not be expected to do so.

It's just your pulse. Sometimes it happens when you get really athletic, your heart beats faster, and you can feel it anywhere, especially in your head.

I assume you are a full-fledged adult. That pulse rate is high at rest. get to see your doctor, especially about the pain on exercise. You could be having myocardial ischemia or angina pectoris. Your doctor will have you do an EKG done to evaluate this.

normal heart rate.. 60-100bpm... it will fluctuate during the day. stress will increase it. after taking a nap.. your dreaming..... nighmares will cause it to increase as well\n\n\nTINA\nregistered Practical Nurse

They are both very good indicators of whether something is wrong. They are the basic vital signs of the body. An elevated temperature can indicate that there is an infection, as your body fights whatever is going on it causes your temp. to go up. Then there are times that a person body temp. goes down. The whole purpose though is so that they have a baseline to work with. They continue to monitor those things and so they will know whether it has gone up or down. The blood pressure is very important. It can tell them alot. Again it is very important to have a baseline to go by. They do indicate if there is a problem. although it doesn't necessarily mean there is something wrong. They just need to have an initial reading so that they have something to go by.

It is different for everyone. Anything less than 60 beats per minute is regarded as bradycardia. Good gas exchange doesn't usually occur at under 60 beats per minute, or over 100 beats per minute. The high end is 100 beats per minute. Anything above that is considered tachycardia for which a medical intervention is required.\n\nNow that being said, when you work out, your heart rate can exceed 100 beats per minute. That is why it is important check your heart rate regularly during exercise to make sure you haven't exceeded the maximum heart rate and also cool down properly when exercise is completed. When you heart rate is high and you stop activity abruptly you can cause yourself to have a heart attack.  When working out it is best to maintain your target heart rate. Below is some helpful information about heart rate.\n\nHere is the formula for the target heart rate. It is different for every age:\n\nhttp://www.stevenscreek.com/goodies/hr.shtml\n\nMiller formula for maximum heart rate:\n\n217-(0.85 x age)= maximum heart rate

It does. It gets your heart rate up and helps blood go to your "spots".

Given the fact that women usually have higher metabolic rates than men therefore, women usually have a slightly higher pulse rate than men.\n\nKeep in mind that there are many other factors that have a much more significant impact on pulse rate than gender.

Well, of course one's heart rate may increase by playing video games.  Playing video games is an exciting experience depending on the game.  There are, of course, some games that are just plain fun and predictable that won't increase one's heart rate.\n\nBut there are games that involve suspense and thrills and fear; those are the ones that increase heart rate, and are no different than any other experience that invokes those feelings.

the human heart is capable of very low heart rates to very high rates. physiologically each heart beat is completed in 0.8seconds, thus the number of heart beat per minute is 60 divided by 0.8= 75 beats per minute. the physiological phenomenon are always given a range value rather than a precise number since every individual is different. hence heart rate ranges from 60-90 beats per minute which can also be as low as 40 for athletes due to vagal tone.

to keep your heart pumping and the blood flowing.

Has to do with oxygen demand.  During exercise your heart rate goes up because oxygen is being used much faster.  The faster pulse gets blood and oxygen to tissues faster.\n\nWhen you stop exercising, there is less demand for oxygen so the heart rate goes back down.  If it stayed high, it would cause high blood pressure and damage the vessels.
