why the body needs to the heart rate back to normal after exercise?

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.

yes these are good healthy exercises as are any exercises that increase heart rate and breathing. swimming, jogging, biking, even fast walking helps.\nAt least 20 min. 30 min better\nOver the age of 40 you might consider speaking to a doctor

Maximum and minimum heart rates depends on many factors. General health, age, wieght, body conditioning, etc. Generally the heart rate for an adult is between 75-80 average. People in good health and shape can lower their rate and sustain it for long periods of time. When the heart beats it transports oxygen and other nutrients to tissue through the blood. If cramping occurs in muscles this is an indication that toxins are not being removed through the same process. Maximum rate is aruond 200, again depending on these factors listed. It cannot maintain this rate for a long time because the heart will become fatigued and quit. This is why when training you should monitor your rate. Increasing the rate from resting is good for a cardiovascular workout but dont over do it. The question about a 0 heart rate and being alive, the answer is yes. In heart attack victims their heart stops but tissues and cells still remain alive for a short period of time. However if they dont resume blood circulation they will die due to oxygen not reaching cells and tissues, and toxins not being removed. (signs of rigimortis). So good to be trained in CPR cuz it can happen to anyone at anytime for any reason.

just keep your heart rate up

You lose weight, you use your joints and muscles, tones your body. Gets your heart rate up for a work out, burns calories. Your body rests.... its over all HEALTHY!

the burning of sugar in your body to produce movement creates heat.  that's why you heat up faster when you exercise.

No. Depending on your age, a normal RESTING heart rate is between 60 and 80 beats per minute. 114 is fine if you were just exercising. But if that is your resting heart rate, I would suggest talking to a doctor.

a normal pulse rate is 60-100. You may need a physical if your HR and BP are up and has never done this before. You may just be out of shape or pushing yourself more, but it may be something more serious like heart rhythm prob or defects, anemia, etc.

unsteady breathing. Breath slow and steady deep breaths and stay calm and you will keep you heart rate down. If youve ever watched a military movie where the soldiers sing to a beat while running use that it puts your whole body to a rhythm which keeps your body calm.

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

195-200 is exceptionally high.  Especially if you are maintaining that for 10-15 min.  You're 25 years old.  Your maximum heart rate should not exceed 195 (220-25) for any long or extending periods during your training.  I would be curious to know what:\n\n#1: what is your resting heart rate?\n#2: what is your resting and active blood pressure before and after exercise.  \n\nYou may have tachycardia (abnormally rapid beating of the heart) which would explain the exceptionally high heart rate during exercise.  My resting heart rate is 55, and the only time I can maintain a heart rate of 195 for any length of time is during a VO2 max test which is no longer than 2min spurts.  It would be physiologically very difficult for any 25 year old to maintain that heart rate for 10-15 minutes (regardless of fitness) without having predisposed tachycardia.\n\nIt's nothing to be too alarmed about as there are many athletes with tachycardia who can still perform quite well, however I would advise you to get it checked out through your Physician and you may require a stress test to validate initial findings.\n\nYou can calculate your risks of exercise including tachycardia here:\nhttp://preventdisease.com/healthtools/articles/exercise_risk.html

after exercizing your cells need oxygen fast, so your heart pumps faster to get the oxygen-carrying blood circulating better.  you need to breate faster to get the necessary oxygen to your heart.

Working out increases body reactions and heart beat. Increased heart beat increases blood flow. Increased bloodflow and pressure from the heart to other parts of the body and from other body parts to the heart makes the veins to bulge. This is a natural thing that happens to all human beings.

Exercise!  Our lifestyles now are so sedintary, but our bodies are built for movement and activity.  Get out, get your heart rate up and break a sweat.  The high you get from exercise leads to a great state of bliss later on and also rids the body of toxins so that you feel better.  Have fun!

Yes, absolutely. Of course the heart rate increases during exercise and one of the long-term benefits of exercise is that the resting heart rate becomes lower. \nAge also has an effect. Infants and children have higher heart rates than adults.

Well, yes, i think so, because of the breathing and relaxing.  When you learn to relax your body, the blood vessels are included.  When you learn to breathe fully the body gets more oxygen and the circulatory system doesn't have to work so hard.  Plus there is significant exertion in those postures (try it with a good teacher and you will see) and you will start sweating and breathing hard if you are out of shape.  So your muscles are getting a workout.

yes a slight increase of heart rate is normal as your body is pumping more quicker to provide more blood through out your body
