what is the effect of exercise on heart rate and heart efficiency?

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).

point out the growing number of obese children in the world\n\nor the benefits of exercise, like, it increases indorphins that make you feel better, therefore increasing the likely hood of a child not becoming anitscocial, and may help prevent underage smoking.\n\nor you could argue the fact that exersice increase brain activity, therefore stimulating ones learning abilities.

Lots of cardio, like running or aerobics, anything to get your heart rate up. And it helps to do at least some light weight lifting. Also make sure to burn more calories than you take in, and drink lots of water, about a gallon per day. Hope that helps!

I am assuming you mean target heart rate. It is based on age and on percentage of max heart rate. As you get older, your max heart rate drops. You can easily find your maximum target heart rate with this simple method. Subtract your age from 220 (226 for women) to calculate your Maximum Heart Rate.  \n\nWarm up --- 50 - 60% of maximum heart rate\nFitness Zone (Fat Burning) --- 60 - 70%\nAerobic Zone (Endurance Training) --- 70 - 80% \nAnaerobic Zone (Performance Training) --- 80 - 90%\n\nor follow the link...

Smoking affects the respiratory system by coating the insideof the lungs with nicotine which decreases the ability of the aveoli to move air. That's why smokers don't have very good stamina for sports. \n\nIt affects the circulatory system by constricting blood vessels. This increases the rate that your heart has to work (blood pressure goes up, etc.)

Exercise has disitinct effects on gene expression in many diffrent tissue types. Beyond the skeletal and cardiac muscle changes that one might expect from exercise, there are studies that indicate changes in gene expression in the liver, blood cells, lungs and neurons. But the largest changes are in the muscle, with an increase in genes related to muscle regeneration and metabolism. Details can be found at: \n\nhttp://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=14519196\n\nbut this is a very technical paper.

it is better for your heart to beat slower, but not too slow. A healthy person who is in shape has resting a heart rate around 60 beats per minute.

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!

Exercise more, eat healthier, and drink more water. It's important to drink water and not caffeinated beverages like soda because then you're drinking calories that you're not burning off right away. When exercising, be sure to keep your heart rate up in order for your heart to get used to the work so you can work out longer and harder in the future.

Maybe not promotes but gives you a good guideline. An elevated heart rate in exercise is necessary to burn calories and fat but it can also warn you if have over exerted yourself and helps you set a pace that meets your needs. Depending on what kind of shape you are in affects your exercising heart the more out of shape the higher the heart rate.

Walking is still good for you, But running/jogging your heart rate up, which is much better for you.  Although if you are not doing anything now, walking is better then nothing, and still good for you, it will raise your heart rate, and burn calories, just not as much as running will.\n\nI know when I'm on a treadmill, i will usually warm up walking, jog for a while till i get tired, keep walking for awhile, then jog again, and repeat that pattern.  But towards the end i will usually just keep walking till I'm completely worm out.

the story goes that running increases your heart rate thereby increasing blood flow throught the body to remove or move lactic acid through the body to reduce soreness. whether or not this is true i'm not sure. but do a search on wikipedia there is a ton of info and external links that can answer this

When you stop suddenly after exercising vigorously, your leg muscles stop pumping and your heart has to pick up the extra work.\n\nTo make your heart beat faster and stronger, your body increases production of its own natural stimulants called adrenalin and noradrenaline. This can cause the heart to beat irregularly, depriving your brain of adequate oxygen, so you feel dizzy and can even pass out.

So is the goal to increase your cardiovascular endurance, or to lose weight, or both? because the two do not necessarily go hand in hand. If you are truly after increasing your cardiovascular endurance, this is what you do:\n\nFor the first 6 weeks or so, do some form of cardio for 20 minutes, three times a week. Now, let's qualify that a little bit. Those 20 minutes do not include the warm up and cool down. While you're doing this activity, you want your heart rate to be at least 140 beats per minute (bpm), and that's the heart rate that you have to sustain for those 20 minutes. You don't want to crank it up to 190, because you won't last for 20 minutes, so use common sense, and estimate as best as possible the right intensity that you would be able to maintain for those 20 minutes.\n\nEach week, increase the length of time by NO MORE than 10%.\n\nThis will increase your stamina by just a bit, but the recommendation for stamina increase is 150 minutes in the Target Heart Rate Zone over the course of a week. You can divide that up however you choose: 30 minutes, 5 days a week, 50 minutes 3 days a week, etc.\n\nHere is how to calculate your target heart rate:\n\nsubtract your age from 220. This is your estimated maximum heart rate. So, for example, if you're 20, it would look like this: 220-20=200. Next, multiply your Max HR (heart rate) by 0.65 and 0.8 These are the values for 65% and 80% of your maximum heart rate. You want to stay between those 2 numbers when doing cardio.\n\nI hope this helps.\n\nGood luck!

cardio is things that bring your heart rate up... exercising your heart and helping your blood flow. cardio can be with equipment or without. sitting in your chair and lifting your legs, and even endurance trainings are part of cardio since they bring your heartrate up fast.\n\naerobic exercises are when you workout without weights or equipment. thus the aero prefix. in older definitions aero prefix was to train your breathing. but modern definitions are non-stress exercises... different college texts show both definitions depending on the training involved.

you'll get the same results.....the whole point is to get your heart rate elevated for a long time...doesn't matter if you swim/run/jump/workout....=]

Your heart heart has to pump harder to go the distance \nto your legs, which also are larger and burn more oxygen\nbut the difference is small.
