I Want Reasons of Hurting Heart

We also put our findings of experiments on the journal in the past year. The man are fit the results of experiments is uncertain and we should study them further. Long period time of exercises may make heart hurt. 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. But the training of long years and high intention has what kind of effect to our heart is unknown.

The clinical observations in recently are showing the sports training of endurance are likely to get arrhythmia. In the duration of training there is a possible of obtaining arrhythmia. There is a guess about the long period exercise may bring about the changes of heart myocardial structure. It affects heart rhythm conduction system.

Spanish scientists design the animal models with rats and do the experiment.

There are two teams of male rats in experiment. They have one team a rest and make a comparison. They use some certain methods to keep the rest of group running. 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

It shows that when the sixteen weeks are coming, the rats who keep on doing running has bigger heart and atrium expansion and lower ability of relaxation that the rats who have a rest. The heart muscle is showing the clear fibrosis signs than in comparison table ago. In the twelve tiredness rats and five rats may induce heart of ventricular tachycardia and there is only one rat of them can cause the disease. The rats that have a rest after eight weeks exercise will have better myocardial fibrosis that those keep on running.

Therefore the scholars think that long time endurance will lead to cardiac muscle fiber and it also may have arrhythmia easily. The research issued on the journal circulation last year.

Because the lives of rats are much shorter than those of human beings and then this experiment of sixteen weeks long time endurance training should put on people to do it . In the other words it is may keep running for over ten years for a man. Only some marathon players and runners may arrive at this result and if they do too much amount exercise. Weather the experiment of animals model is the same with the human beings or not, there is need to use people to do a medical survey to check.
