ANATOMY

Detailed explanation-1: -If an aerobic exercise is performed for a long time, it will affect the parasympathetic nerve, thus increasing stroke volume and lowering the resting heart rate, which has a positive effect on reducing cardiovascular diseases (Riebe et al., 2015).

Detailed explanation-2: -Resting heart rate (RHR) is positively related with mortality. Regular exercise causes a reduction in RHR.

Detailed explanation-3: -That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles. This means the heart beats fewer times per minute than it would in a nonathlete.

Detailed explanation-4: -If a person is an athlete or does a significant amount of exercise, they will typically have a lower RHR. This just means their heart is more efficient at pumping blood around the body and does not need to beat as fast. A lower than average RHR is not a cause for concern unless it causes other symptoms.

Detailed explanation-5: -Heart rate – changes within a couple of weeks Resting heart rate can decrease by up to 1 beat/min in sedentary individuals with each week of aerobic training, at least for a few weeks. Other studies have shown smaller reductions with fewer than 5 beats following up to 20 weeks of aerobic training.
