The long endurance may make our heart broken. The experiments of rats give the results of problem of heart and we may also use man to do this kind of test. There are three different time of periods in this experiment. The result published on the magazine last year.

I am afraid that we can get heart hurt from long time of endurance training. The topic that people often are interested in has the effect of long time and endurance running to our heart. We all agree with the right amount exercise. What actually happen to our heart is uncertain if you have exercise of long years and high intensity.

The clinical observations in recently are showing the sports training of endurance are likely to get arrhythmia. It does not occur in the course of running. There is a guess about the long period exercise may bring about the changes of heart myocardial structure. It has effect on the heart rhythm transmission.

Spanish scientists use rats to design for animal models and then carry on an experiment. There are two teams of male rats in experiment. They have one team a rest and make a comparison. The other group was made to go on running in some other ways. The time period is designed to four weeks, eight weeks, and sixteen weeks. Atrial ventricular changes of rats in two teams are studies by microanatomy and biochemistry at last

The findings of results is that there are some changes between the tiredness rats and the sabbatical rats, for example the rats of first group have larger heart and atrium expansion and the low capability of diastole at the sixteen weeks. The heart muscle is showing the clear fibrosis signs than in comparison table ago. There are five rats are likely to get the heart of ventricular tachycardia in twelve tiredness rats and one of them will happen this situation in the comparison table. The myocardial fibrosis will turn better when the rats have a rest after eight weeks training and the myocardial fibrosis of rats who keep running is not turning better.

Therefore the scholars think that long time endurance will lead to cardiac muscle fiber and it also may have arrhythmia easily. The study published in the Circulation magazine of last year.

For the lives of men is much longer than those of rats and therefore we ought to use the man to do the sixteen weeks long endurance . In the other words it is may keep running for over ten years for a man. In order to finish such large amount training and there are only some the runners in the marathon or some long running runners. The experiment will be suitable for the man is unknown, we need to use people carry on investigation to verify.
