Cardiovascular efficiency depends on a number of factors. One measure is called stroke volume, which is the volume of blood pumped per heartbeat. A fit individual has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat. This is also the reason fit people have a lower resting heart rate. As mentioned, muscles reqire a given amount of fuel, even at rest, which doesn't change with exercise training. Because exercise training has increased the volume of oxygen that can be delivered to muscles per heartbeat, the heart needs to beat less to do the same job. Therefore, the heart rate is lowered.
What else can I help you with?
When heart rate is increased the time of ventricular filling is?
. . . decreased.
Do the vagus nerve increase heart rate?
it decreased heart rate , since vagus nerve innervate parasympathetic never and we know parasympathetic nerve reduce heart rate.
What type of action does negative chronotropes exhibit?
Decreased heart rate
What is the normal compensatory response to a decreased cardiac contractility often seen in myocardial infarction?
Increase in heart rate as Cardiac Output = Heart rate x Stroke volume. As SV will be decreased, HR increases to compensate.
Do sport drinks affect your heart rate while excercising?
yes
If you have just placed an advanced airway in a patient with a respiratory condition and his heart rate decreased what BEST explains the decreasing heart rate?
Most likely you have pressed on the vagus nerve that controls parasympathetic innervation to the heart.
What is the Medical term meaning decreased pulse rate?
The medical term for decreased pulse rate is bradycardia. Bradycardia is a condition characterized by an abnormally slow heart rate, typically less than 60 beats per minute in adults. It can be caused by various factors such as heart disease, medication side effects, or an imbalance in the body's electrolytes.
Does the speed you go in a sport for at least a half an hour effect your speed of your heart rate?
Yes, the heart rate is pumping harder to get oxygen to the muscles in your body.
Is there damage to the heart if you are underweight?
Risks to the heart associated with being underweight include:Anemia, the capacity for blood to carry oxygen is decreased due to low iron content and thus the heart receives less then the proper amount of oxygen it needs.Arrhythmias, because the body does not get enough calories to function it modifies common activities such as heart rate. Decreased heart rate leads to low blood pressure, both of which can led to heart failure.
How does cocain effect sport competitors?
It raises the heart rate giving them extra energy
What sport will accelerate your heart rate the most?
running because when you run you breath harder which makes your heart beat more
Can you give me examples of aerobic excersice?
There are many types of aerobic exercises you can do. Examples are running, fast walking, swimming, biking, and any sport. As long as you get your heart to it's target heart rate it is considered aerobic.
