Question

How is the pulse rate affected by changes in the activity of an individual?

Answer 1

when a person's activity increases, pulse rate increases because muscles contract rapidly and glucose and oxygen have to be supplied to them at a faster rate for aerobic respiration to occur at a faster rate, which is achieved by a rise in the heartbeat.

When a person is less active, muscles contract less rapidly so a lower rate of supply of oxygen and glucose is sufficient as energy has to be obtained at a slower rate, so pulse rate decreases.

Answer 2

For the most part, pulse increases with changes in activity and hormones. When adrenaline (epinephrine) is released into the blood stream, your pulse increases. Also note that circadian rhythms effect the pulse of individuals. A circadian rhythm is the bodies internal clock. When it becomes night time, the pulse actually decreases and vasodilation occurs causing people to feel colder than it really is.  

Answer 3

well, if your activity level goes up, so does your pulse

Answer 4

The more active the individual is, the faster the pulse/heart rate is.

The heart has to  pump faster so that the red blood cells which carry oxygen can bring oxygen  to oxygen depleted muscle cells.

Try counting your pulse at the start and the end of a one mile run.
