When a person engages in physical activity, he undergoes aerobic situations where the heart muscle is optimally strained and improves its muscle strata.

There are scientific studies that compare the muscular walls of athletes and sedentary people, the walls of athletes are thicker and have more power when it comes to pumping and ejecting blood, that is, they make fewer contractions of the heart muscle but more effectively due to They eject more blood, while in unhealthy or sedentary people their muscles are weak, and they pump less blood into the torrent for each contraction, so they need to compensate for non-ejected blood volume by contracting more times and therefore increasing the heart rate.

Thus, physical activity generates a more effective contraction, which is why the heart rate of athletes is lower.

In the case of blood pressure, blood pressure is lower and there are no atheroma plaques or fatty tissue accumulation as in the case of sedentary patients.

Venous return in athletes is aided by contraction of the skeletal muscles of the lower limb, so cardiac filling is better and the heart has less energy demand (this does not happen with sedentary).

Explanation:

In summary, the heart rate is decreased by the great contractile power of each cardiac pump, the blood pressure is decreased by the low cardiac demand and by the good blood circulation, the venous return is favored by the contraction of the skeletal muscles of the Lower limb and myocardial walls are much thicker or hypertrophic due to good oxygenation and sports activation during physical activity.

because he needs . im 12 i dont know srry if wrong
