Maximum stroke volume (the volume of blood pumped from the heart)
is fairly constant -
thus to increase cardiac output you must increase heart rate.
Note that increasing the heart rate WITHOUT increasing the return blood flow to the heart (which does happen during exercise),
all that happens is that the stoke volume drops.

What would tachycardia be for a 14 year old girl?
Tachycardia is an increased heart rate. Increased heart rates can be caused by exercise, illicit drugs, hormonal changes, or an electrical malfunction with the heart itself. When a person experiences tachycardia of unknown origins you need to consult a physician.
Which of the following would cause the greatest increase in cardiac output?
Increased heart rate and increased stroke volume
What would result from consistent aerobic exercise?
Consistent aerobic exercise can lead to improved cardiovascular health, increased endurance, and weight management. It may also help reduce the risk of chronic diseases such as heart disease, diabetes, and obesity.
What if your ability to lift that heavy couch would be increased by which type of exercise?

What would happen if heart rates did not increase with exercise?
die
Would you recommend that someone with asthma exercise regularly?
Yes, they should do exercise regulary.
What would happen if someone injected meth into their heart?
If someone injected meth into their heart it would kill them.If someone injected meth into there heart, it will increase the speeds of their breathing, heart rate, thoughts and actions.
What effect does exercise have on a persons heart rate?
The heart is a muscle, and exercise is great for it! Strength training helps to enlarge your blood vessels so the blood flows quicker, which means the heart won't have to beat as fast (or work as hard) as it would in someone with smaller vessels. Cardio exercise, such as aerobics, kick-boxing, or even a brisk walk raises the heart rate which also makes the heart stronger so that it can endure more. Basically, the stronger the heart is the better it works! You should try to do a combination of both, as this is the best way to help your heart stay healthy!
Why is is exercise good for your heart?
Exercise gets your heart used to beating quickly. As the heart is a muscle it needs to be used. The more it is used the stronger and more efficient it becomes at pumping blood. The increased blood flow that exercise causes (due to more oxygen being needed) cleans out extra cholesterol that may be in your blood vessels. Extra cholesterol is one of the courses of strokes and heart attacks. If you haven't played a sport for twenty years but you just sit behind a desk all the time, if you start intense exercise your heart would not be used to it. Your heart would beat faster and faster until it ultimately could not handle it and it would form a blood clot. Soon after your heart would not be able to beat thus creating heart attack. So the point is you should exercise to prevent this scenario from becoming reality. Table tennis (ping pong) is an awesome exercise for the heart, plus its easy on joints. Answer 2: Start off by just walking, add more distance each time you walk. Put pep in your step and increase your speed. Walking uses all muscle groups. Do deep breathing in and out so you do not get winded while walking. You will be amazed at how you will feel after walking and any form of exercise.
How many times does a human heart beat in an average lifetime?
The average heart beats 80-100 beats per minute at rest. Therefore in a year it would be 42,048,000 - 52,560,000 just at rest. That amount would be increased depending on the amount of exercise that person does.
Why would a Heart beat hard?
The heart beat can increase due to stress and exercise. There are many other factors that can increase heart rate.
Which study would likely be used to investigate the hypothesisis?
I don't quite understand what you're saying as it doesn't make sense. A hypothesis is a statement made before a test is done, and is compared to the results. It usually requires the three words If, Then and Because. For example if you were testing exercise and its effect on heart rate, a hypothesis would be "If the exercise intensity is increased, then the heart rate will increase, because your heart helps with exercise"What your asking is what study would be used to figure out its hypothesis, which is a redundant question as all studies are based on testing its hypothesis, which is a paradox. Please ask a less complex, unanswerable question next time.
