Have you heard...
...THAT A HUMAN HEART BEATS UP TO 4 billion times in the course of a life ?
The heart rate of a healthy person underlies several influences. It depends upon intensity, age, and physical fitness. The human body is supplied with oxygen and nutrients by each heart beat. The resting pulse rate of an adult person is 60 to 90 beats/min on average. The frequency falls in the course of a life. In contrast to a newborn, the beats/min of an adult are reduced by 40 to 70 beats.
The rest heart rate can increase up to the maximum heart rate by exertion. The maximum heart rate is often determined by the general rule 220 - age. Besides the rest heart rate, the maximum heart rate drops as well with the years. Heart rates can more than triple under exertion and halve in rest for stamina trained persons in contrast to unfit persons. A stronger heart lets circulate the same quantity of blood in the body by less beats.
When you calculate with an average heart rate of 90 beats/min, it makes 3.5 billion heartbeats in 75 years.
Example of calculation: 90 x 60 x 24 x 365 x 75 = 3,547,800,000
The human heart is a great excemption among hearts of mammals. The heart of most mammals beats about one billion in the course of a life. In general: the smaller an animal the higher is the heartbeat per minute. Examples for heart rate of animals:
- shrew: 800-1200 S/min
- humming bird: 800-1000 S/min
- squirrel: 320-360 S/min
- monkey: 170-200 S/min
- rabbit: 150-200 S/min
- dog: 80-120 S/min
- cat: 80-120 S/min
- horse: 30-45 S/min
- elephant: 15-35 S/min
The heart, the most important muscle in the human body, should be exercised and nursed. Sports and healthy nutrition ensure rhythmic contractions, by which the blood is pumped into the body and essential organs are supplied.
Improve the function of your cardiovascular system by regular stamina training and keep healthy.
