Heart benefits of training


• More muscle: with exercise, the heart becomes larger.

• Slower Pace: beat fewer times per minute at rest and when an effort is made.

• More power: because the pulse rate decreases, the amount of blood pumped per heartbeat increases.

• major arteries: the diameter of arteries becomes larger than normal to allow more blood flow.

Exercises to stimulate the heart and caring


Although it is common knowledge that regular exercise helps maintain a healthy heart, a group of scientists believes it has succeeded in showing why. The exercise stimulates the growth of new blood vessels. Contrary to what happens with the anaerobic metabolism that uses sugar as a source of energy, aerobic metabolism breaks down fat for energy.

The team of researchers from Duke University studied what happens in mice when they exercise in a running wheel. The training exercise stimulates the production of a protein called vascular endothelial growth factor (VEGF by its acronym in English).

VEGF stimulates the growth of new blood vessels or angiogenesis. The number of capillaries feeding the muscles increased and trained some of the muscle fibers that had been working anaerobically changed to work aerobically.

Artificial heart: Good performance


Research conducted with the CardioWest artificial heart has fully demonstrated that both orthotopic replaced the original cardiac ventricles and all cardiac valves. Is eliminating the problems often seen by professionals in the bridge to transplantation periods with left ventricular assist devices and biventriculares.

Among these include the right heart failure, the ventricular thrombus, intraventricular communications, and low blood flows. A new U.S. experience indicates that the introduction of completely artificial heart improved the rate of survival to cardiac transplantation and survival after transplantation.

"This device prevents death in critically ill patients who have irreversible biventricular failure and are candidates for cardiac transplantation, has shown the study director of the Sarver Heart Center. To obtain the study data were not randomized, prospective five sites, using historical controls.

The lovers are dangerous and can kill

Peter Skrabanek, (cardiologist at University College Dublin), has published the long list of the 246 (for now) risk factors for heart disease and arteries. Besides the best-known as high blood pressure and excess cholesterol in the blood, there are unusual and curious.

In front row: being bald, of small stature, having extramarital relations, live in the city, have a little loving wife and not eat mackerel. Also weighing on the hearts slow growth of beard and not to eat garlic.

Physical activity combats hypertension

It is not a novelty. Indeed, is already a fact well proven. The cardiofitness, namely physical exercise can push up the performance of the cardiovascular system, exerts beneficial effects in hypertension.

And in mild forms, with pressure values somewhat higher than 140/90, which doctors define as "frontier" may even blood pressure returned to normal values, without having to take pills. Numerous studies have shown that aerobic exercise characteristic of cardiofitness causes a decrease in blood pressure maximum and minimum sleep.

The mechanisms by which this effect occurs are partially known. For example, aerobic activity determines an increase of the capillary network of muscles in the periphery: in this way the same blood flow is distributed in a "tree" bigger and low pressure. Secondly, sport moderate influence on the system of endocrine glands.

What does? Decreases catecholamines, stress hormones that cause the narrowing of blood vessels peripherals, play an important role in the onset of hypertension. However, while making sport benefits the tension, it is essential to choose the appropriate discipline, and to establish accurately the intensity, frequency and duration of effort.

The physical activities more suited to normalize the pressure are jogging, race, swimming, running, walking, cycling and cross-country skiing. And when, during the winter, cardiofitness exercises must be conducted indoors, in the gym is available a wide range of appliances such as treadmills, exercise bikes and step.

Semaphore red, however, for sports that involve anaerobic efforts (as in the shorter sprint distances, the shot put and body building). In any case, to obtain the maximum benefit, exercise should dosificarse with extreme caution, as if it were a drug, because it can be
dangerous, a kind of double-edged sword, if performed without judgement.

The program of physical activity, for example, may include 40 or 50 minutes of training, three or four times a week. What pace should continue? Surely we must avoid the high intensities. The exercises are the most effective light. Experts agree that, ideally, consider keeping the heart beats 60% or 70% of the maximum heart rate, better determined in laboratory with a traditional stress test, rather than with the classic formula '220 - age. "

The most rational and safe to control the intensity of physical activity to which we are dedicating Pulsómetro is to make use of. This device provides a continuous and reliable information about the heart's response during the effort, avoiding the risk of working at levels of heart rate too high regarding the scheduled by the cardiologist.

The Pulsómetro is a perfect guide when it should be very accurately assess performance and maintain control under the regime of training. It also allows control the heart rate and alerts with programmable alarms when they are exceeding the preset values.

1 Year without doing physical exercises - Its effects

How you care.
If you feel you've lost flexibility when you stretch collect an object from the floor, or feel an extreme tiredness after having risen only three floors down the stairs, then you're faced with two symptoms you indicate that your physical condition has fallen to a point where probably avoid as much as possible the exercise because you get tired more, so you move less.

If you have access to a road, you can raise your speed gradually. It starts the first days walk four kilometres to step fast, once you've become accustomed, travels the same distance, but Trot. Then you will run. To achieve aerobic exercise have recommended, you need your heart to work to 70 percent of its maximum rate. To work at this rate you should subtract your age to 220.

You can also use a watch with a heart rate meter put that on your wrist, to constantly measure and motivate. How long you take. If train seriously, you could run a marathon after five or six months. But after the first three months you're fit.
Never too late, and among younger you are, the faster gain physical condition. If you have more than 35 years of age and have a history of high blood pressure, heart problems, diabetes or asthma, visit your doctor so you can make a medical examination before starting your routine.

The love scientifically

Loving obsession
What do you search in a couple? (Besides a spectacular rear)
Forget the rules to manage a relationship!
"Person's type that search emotions is prone to fall in love."

What do you feel when being in love? To many people it beats you strong the heart, they sweat you the hands, they cannot eat neither to sleep, and the whole time spends thinking of that so special person. You are as if the love was a state that have your own symptoms, and many scientists have begun to study why they happen these symptoms.

Dr. Love
"The great legal age of people knows what feel when being in love, exactly Dra you say. Helen Fisher, an anthropologist of the University of Rutgers and expert in the topic of the love. Your new book, Why We Love (why we love), analyzes this process from a scientific perspective.

The scientists as Fisher have studied the process of the love to determine what happen in our brains exactly. They have discovered chemical substances that cause all type of reactions, from ecstasy until attachment, and they identified three different modes in those that people are related with your couples: I want, love and attachment.

Desire
In what concern to the desire, the feeling of carnal appetite for another person. the chemical responsible substance is the testosterone. Although you generally associate the testosterone with the men, Dra. Fisher points out that as much the women as the men have high levels of testosterone when they are attracted by somebody. If at some time you felt an irresistible desire to play somebody, you are possible that the testosterone is the responsible one.

Love
The following stage, the romantic love, is what most of people imagine when they think of the love in general. When raising the level of certain substances called chemical dopamine and noradrenaline takes place the exaltation sensation and ecstasy that many of us feel when starting a new relationship.

Although to be of boyfriend doesn't seem to have much in common with certain sports that they involve such adventure as surfing or mountaineering, the goods on the brain are similar. people feel full with energy, excited, in the summit of the world. The love is touching, and person's type that search emotions is prone to fall in love, Dra says. Fisher.

But not all are so delighted to venture. "Not there is doubt in this respect, some people fall in love followed than other, Dra says. Fisher. You depend on the legal capacity, perspective and last tests. "If one raisin for such a painful test that you leave you thinking 'nevermore, you will take much more time [in falling in love again]," Dra says. Fisher. To trust your couple is very important, because you are that what allow to communicate honestly.

Attachment
The final stage of the love is the attachment. You are when two people decide to cohabit long term and they have found a level of comfort the one with the other one that sustain your romantic feelings.

If you are wondering how to take your relationship at this level, Dra. Fisher has some ideas: "Make things outside of the routine." The novelty impels the dopamine levels and other elements in the brain, she says. These other elements include the substance chemical oxytocin, a soothing substance that he/she help to that a person sits down attachment for the other one. The physical contact is it you make that the oxytocin levels increase. "Even when you make massages to another person, they go up the oxytocin levels, Dra explains. Fisher.

Making that you work
Now that you have learned on the science of the love, you can take a moment to return to the alcoholatura thing. The physical contact as to take by the hand and to be hugged can deepen the link with your couple. Dra. Fisher also makes stress in the importance of being open and I am honest. "You are about sharing secrets with your couple, she says. To have good memories together and to learn how to discuss in a constructive way, they are other good ways to achieve a durable love. Therefore, if you trust your couple, you open your heart. Your brain will enter in share.

The love

So much is written about the love... but you seem that all that is never overworked that one can say of the one.
In general ledger or pettier measure all the human beings feel love at some time, until the most unscrupulous they have had some object of your affection. For the love we are moved, us vulnerabilizamos, we ennoble ourselves... for the love we fight, we dream, let us believe... for the love we suffer, we cry, we remain silent, we scream... the big works of art, the best songs, the unforgettable books, all they have been motivated by the love.

The love is considered as a group of behaviors and attitudes, unconditional and disinterested, that are manifested among beings able to develop emotional intelligence. The love is not only bounded to the mankind but also to all those beings that can develop emotional nodes with other, for example, dolphins, dogs, horses, etc.

Habitually he/she associates the term with the romantic love, a relationship pasional between two people with an important influence in your relationships interpersonal and sexual mutual societies. However the term is also applied to other different relationships, such as the platonic love or the family love, and also in a more comprehensive sense it is spoken of love toward God, the nature, the humanity in your group (that which usually associates to the empathy), and others. In most of the cases it means a great affection for something that cause pleasure or happiness to who carry out the share of loving.

Philosophically, it is usually thought that the love is the only feeling that don't possess a feeling of polarity, like you are the case of the other feelings (p.e. peace - war). Popularly it is usually contrasted, avoided or counteracted with the hate, contempt or selfishness, but a polar defined feeling doesn't exist.

"The love is suffered, you are benign; the love doesn't have envy, the love you are not boastful, you don't get conceited; you don't make anything undue, you don't search his, you are not irritated, you don't harbor resentment; you are not enjoyed the grievance, but one enjoys the truth. All you suffer it, all you believe it, all you wait for it, all you support" it.

In your etymological origin, the love has roots in some Greek words. One of the translations means similar, because those that love each other are similar; another is to want vividly: love involves a to want intense and vehement; another means to tie, to connect, because the characteristic of the love is to adjoin the lovers.

We can say that the formal object of the perfect love are in the person of the "other" one: something is loved because you are good, because you embody the nature of the good: "something is loved as soon as you are right of well." That which are not equal to affirm the precedence of the interested love and the subordination of the very subject to the lover. Because the well is not good because you are tempting, but rather you are tempting because you are good. To affirm that the well is the formal bjeto of the love you are to not only found the ecstatic or disinterested character of the love, but founding the love without more.

The love that carry out me and you perfect as human being you are not unmotivated, you have lawsuit. We can summarize the lawsuit of the love like the very objective and actual of the dear person. To love is to delight in the good that you exist in the other one. And that love can discover it in different ways: when I love somebody: you are an active and immediate test, the direct object of the love you are the other one; when I observe the love in other people that love each other: you are a mediate test; and the most special form is when I am loved: you are a passive and immediate test and the object of the love I am myself. All these tests help to understand what are the love: affective or pleased statement that a human being makes of the existence of the other one.

The love is the uptake of the fullness and another person's perfection as long as susceptible of being carried out by oneself and as long as in the realization of that fullness he/she goes involved the own autorrealización, so this can reach a fullness before unsuspected. Said shortly, the love is the uptake of another one of whose fullness the own one depends, and in such a way that that other one awake the best thing that is in myself. From this perspective, the love is a feeling and a trend.

In the love he/she takes place, because, the union of two subjectivities so each a stocking in the fullness of the other one. For that reason, Aristotle maintains that the work of the love is the drive, S. Agustín that the love is the trend to the drive and Hegel that the love is the drive of the identity and the difference, that is to say, the drive in which two subjectivities reach the identification of one with the other one but without that supposes your annulment, on the contrary, in such a way that the difference stays.

Not we were created neither to be neither to be alone. Nobody grows neither you are formed alone. Our existence is always toward the other, bound, in communion with the other ones. We can say that in first instance this personal necessity is vector; this means like an arrow, with an address. I need a person with an intensity and with an inclination or very precise orientation. I need it for something, I don't need it personally but for that that the person has or you take I get; your body, your effort, your dexterity, your social misalignment, your support...

Each being's natural appetite for your well would be the fundamental and only form of the love.
Of the whole field tendencial of the human appetites they emerge the answers to the good or those not well offered ones; these answers can call them affective. The well moves the immediate appetite, inside which we include to the love like exclusive motor of the affective life.

The children, in your purity, they are usually the clearest when explaining that you are the love:

"When somebody loves you, the form in which say your name is different"

"Love is when you exit to eat and ofrecés your French fries without hoping the other person offers you your French fries"

"Love is when the mom sees the dad all stinking one and of bad odor and you say that you are but beautiful that Robert Redford"

"Love is when you tell to a boy that take a pretty shirt and he put it to him every day"

"Love is when your dog licks your face although vos the alone dejás the whole day"


* The love is silent. why do I love you? Because sos vos. Not there is reason some and you are vain to search one.
This inferior love of the desire is an authentic love, and you should not be rejected in any case, but you contain more than an element of selfishness and neither you rise as high as the love in your plenum perfection that go beyond all the desirable qualities of that loved, directly to that loved as person. You go beyond your personality, until reaching your me, this is, an I that your own kindness subsists, don't eat to perfect of the lovers, but as loved by itself, in your own person.

* The love is communion. The lovers love each other, but they remain in toto in themselves, in a certain sense, the love is one, but in another sense it is two. As for one he/she refers to that are a link that bind, based on the likenesses and, in the deepest love, an image of what you/they can end up being together, of the recognition of the possibilities that you/they increase to have to the other one to the side.
The communion in the love requires community in kindness, the love is don in the sense in which the union doesn't delete the two lovers. The term of the love is the identity of the other one, your unique subsistence as person.

* The love is a don of yes. Only in the measure in that I love to other I really love myself to myself. With my love, I give myself, in present, to the other one. This autoentrega is indispensable for the plug-in of my legal capacity.

* The love is creative. Not it is a dream sense or lazy rest, but a vigorous handover toward the realization that make grow in the lover's appearance.
The love doesn't create the original legal capacity of the other one, but rather you find it. Being loved exists in the world, you deploy your legal capacity, and simply to be who are he/she has made your being to shine in that of the other person.

*The love is reciprocal. To love involves as much the desire as the fact of being loved. You are possible to have a love that are not corresponded, but satisfactory character of similar love jumps at sight, this desire to be loved manifests the unavoidable component of the love of itself in all love, a love of itself that he/she don't need in mode some to be selfish, but you are simply the consideration of the value of oneself as person, exactly in the same way that one considers the value like person of the other one.

*The love is the supreme value. The love must be everything or anything. Neither in your actual financial year, because we can love more or less, and never to love perfectly. The love doesn't oppose you to the existing reality some, but rather you animate them to all respecting them. The love is your own value, you are the person's value.
