Everyone knows that physical activity, mental stress, emotional outbursts affect the work of the heart. Sometimes you can hear the opinion that the organ of a person who constantly experiences significant physical exertion wears out faster. After all, the heart has to beat more often, it does not rest. Is it really? Are there any norms? How many beats per minute should a heart beat? Does his work change under the influence of constant loads?
Strengthening the work of our “internal engine” can occur due to the ejection of a large portion of blood into the artery with each reduction. If the number of cycles increases, then this also leads to increased cardiac activity. Which of these methods, which make the most important organ work hard, is more profitable for him - for a long time this has not caused controversy among doctors.
Heart of an untrained person
The muscle of this organ of an untrained person is weak, so it is unable to push out a large volume of blood. This fact has long been known to everyone. In this case, blood circulation can be increased only by increasing heart rate. With this method of heart function, the pause time is reduced. But the muscle of the “internal engine” must get rest precisely in this period of time. This means that the heart of an untrained person quickly gets tired, but has little rest. With significant physical exertion, an increase in its performance occurs no more than 3 times and only due to heart rate.
How does a trained body work?
In trained people, an increase in heart performance is most likely due to an increase in the volume of blood ejected into the aorta. Therefore, the resting time of this body is almost not reduced, and he manages to relax. With very high physical exertion, a trained heart can increase its performance in two ways. Firstly, due to the shock volume (2 times). Secondly, due to heart rate (3 times). Total - increase in efficiency by 6 times.
Heart Training Rules
It will be useful to know each of us. When an untrained person starts immediately to great loads, this leads not only to a general painful state, but also to oxygen starvation. And all human organs, including the heart, are sensitive to oxygen deficiency.
At the same time, it is known that weak loads do not give a training effect. Therefore, the intensity of the exercises must not only be gradually increased, but also correctly dosed.
Active work of the heart during training provides him with the opportunity to contract less often at the time of rest. This mode of his work is most beneficial for the restoration of activity.
When performing exercises for muscle training, it is important for a person to know how many beats per minute the heart should beat, and depending on this, regulate the amount of physical activity. Many do not attach much importance to this aspect, and in vain.
Heart response to dosed load
With a simple test, anyone can find out to what extent his “internal motor” is trained. To do this, first count the number of heart beats per minute at rest. You can perform 3-4 measurements and find the average value of this indicator. Then they perform 20 squats, after which they immediately record how many heart beats per minute were counted. Such measurements are performed every 20 seconds for 3 minutes. All indicators should be fixed. Next, you need to conduct a small comparative analysis. The results are considered good if the heart rate after exercise increased by one third or less from the readings of the resting state. If the frequency of heart beats per minute increased by half, the result is average. And when the indicator is more than half, the result can be considered unsatisfactory.
What pulse is considered normal
So how many beats per minute should a heart beat? This indicator primarily depends on the state of human health. It is believed that the healthier it is, the lower the result of heart rate. It may depend on other factors, for example, on age, fitness, the presence of a load at the time of measuring the pulse, medication taken, body position, air temperature.
In an adult over the age of 18 or more, heart rate is from 60 to 100 beats per minute. For a trained athlete, it can be 40 strokes, for champions in cycling, the indicator was fixed at 22. In children of different ages, heart rate ranges from 160 to 75 muscle contractions.
Does health depend on heart size?
The result of training and a healthy lifestyle can be a strong, hardy, big heart. But it turns out that the increased mass of this organ is not always indicative of the fact that it has become more resilient and efficient.
An increase in heart mass can also be found in alcohol lovers, people leading a sedentary lifestyle. The muscles of the organ are gradually destroyed, in their place is formed connective tissue, which is filled with fat. Such a layer cannot contract, therefore, the heart, having a large size, still works weakly and is prone to various diseases.
To prevent vascular diseases, each person must know how many beats per minute a heart should beat, how to calculate this indicator, how to regulate it. For these purposes, you can purchase a special device, which is placed in the chest with a special strap. Heart rate measurement is continuous, so you can get reliable data on the work of the heart for a certain period of time.
