Because the stroke volume (amount of blood pumped per contraction) increases in the trained individual. Therefore to deliver the quantity of blood needed to support metabolism in the resting state, you heart needs to beat less frequently.

∙ 14y agoIt goes lower than the resting heart rate because when you exercise, your heart pumps faster. And when you stop, it has to slow down rapidly to stop you collapsing or hurting yourself. Then it goes to normal resting rate after about 30 seconds.

∙ 14y agoResting heart rate only decreases when the heart becomes stronger. This is done through many hours of exercise. The heart wall of the left ventricle in particular (which is the chamber where blood leaves the heart to the body) becomes stronger and thicker due to exercise and therefore the heart rate will decrease.
There is a formula which shows this easily.
Cardiac output - Q - the amount of blood pumped by the heart per minute
Stroke volume - SV - the volume of blood pumped out by the left ventricle per contraction
Heart rate - HR - the number of times the heart beats per minute
Q = SV x HR
untrained person - Q = 60ml x 80 b.p.m = 4.8 litres per minute
trained person - Q = 80ml x 60 b.p.m = 4.8 litres.
the stroke volume has increased, so the heart rate can decrease because the heart is still keeping up with demand.

Why does the heart rate change while we are resting and during exercise?
while resting our heart doesn't have to work as hard but while we are exercising that causes more blood to pump through our body causing it to beat faster than usual
Why does a person heartbeat slow down when he or she is resting?
Because your body is at rest. Your heart rate rises when you are moving, exerting energy, exercising, etc. When you are at rest, that is your resting heart rate. If you have a fast heart beat while at rest, you may have high blood pressure or another heart issue. Exercising regularly can lower your resting heart rate. in other words: As the person is at rest you dont require so much energy, so as less energy is required the cells respire at a slower rate, as they respire at a slower rate they require less oxygen and glucose( which is carried in the blood) hence the heart pumps blood at a slower rate due to which the heart beat is slow.
