Sports and sports-related sudden death is sudden death referred

 Generally defined as: with or asymptomatic athletes and people from exercising, in motion or movement within 24 hours after the accidental death. Stressed the incidence of sudden death in sport or exercise, but also patients from onset to death in the tens of seconds, within a few minutes, this is the most important features of sudden death during sports.

In fact, all around us, or a variety of reasons due to unscientific exercise and sudden death are also many people, and gradually showing an upward trend.

cause of death:

motor evoked potential disease

1, died suddenly

cause unexpected movement of cases on June 6 1:2008 a university in Nanjing gym class, a freshman collapsed and died.

Case 2: A New Life in a University Department of Computer Science at 5 pm the day after the end of military training, but also played basketball for about 1 hour, about 7 pm in the dormitory collapsed, rescue failed death. What

sudden death during sports? Like the case, as is the man in motion, or movement within 24 hours after accidental death.

2, there must be potential disease

Case 3: A Beijing high school student run sudden death in physical education courses. The students usually like sports, the body looks good, according to the students about his day to the school, the

Case 4: Yulin, a communication company employees and friends to the arena for a play, a sudden plunge down to the ground, sudden death. According to friends, he was 35 years old, good health and physical examination did not find the heart over the years, blood pressure, there is a big problem.

70% ~ 80% of exercise sudden death is the result of motor evoked potential caused by cardiovascular disease.

potential root cause, including stroke, respiratory diseases. When an old comrade Pa Xiangshan Beijing sudden death, autopsy, died of a brain haemorrhage.

overload exercise an incentive:

(1) myocardial hypoxia can not be: if our heart because of different causes, and some defects, such as closing some of ventricular dysfunction, is not in the exercise The pump out the blood, the occurrence of that back, can still meet the needs of the body; but after the movement began, cardiac output can not meet the needs of the whole body metabolism.

and man in motion, the rapid increase in myocardial oxygen demand, myocardial oxygen can not, if insufficient blood supply and hypoxia, myocardial cells will be reduced aerobic metabolism, productivity decreased when heart activity can not provide the necessary energy, can lead to myocardial infarction.

(2) sympathetic nerve activity: exercise catecholamine levels, sympathetic nerve activity increased, more likely to lead to vascular spasm, acute myocardial ischemia, necrosis, arrhythmia; or cardio-cerebral vascular rupture, causing heart arrest.

(3) characteristics of young people: Why do young men prefer death? An underlying disease of young people do not show, so they thought that he is very healthy; Furthermore, young energetic, can not help but do exercise overload.

sudden death disease:

(1) coronary atherosclerosis: This is the number one ranked risk factors.

general, coronary artery stenosis greater than 75%, and the job will appear angina, ECG can be found fault with it. Coronary artery stenosis with mild symptoms in the general activities, but physical stress, due to endocrine changes, catecholamine secretion, heart rate, blood vessels, may induce coronary artery spasm, increased myocardial ischemia, or necrosis.

(2) hypertrophic heart disease: acute sudden death of 48-50% of the reason. Hypertension is caused by mutation and an important reason for cardiac hypertrophy.

concentric left ventricular cavity to the heart of the expansion of pathological hypertrophy, myocardial contraction not only weak, but also occupied the ventricular filling space, usually can still meet the physiological needs, exercise, then myocardial oxygen supply may cause inadequate.

(3) congenital anomalies of coronary blood vessels and the angle offset, narrow and so on.

(4) myocarditis: it is caused by a viral infection, is more common in young adults. The onset of acute myocarditis can lead to heart failure.

Qingdao, there was a 19 year old soccer player game, there is no collision in the case of a sudden fell to the ground and died. The player is usually in good health, his family and the team did not know what his or fatal congenital disease risk. Some experts speculate that if one to two weeks before the accident, he won the upper respiratory tract infection,UGGs, then you can conclude that the basic reason for his sudden death caused by a cold episode of acute myocarditis.

(5) valvular heart disease.

(6) cardiac conduction abnormalities.

(7) Marfan syndrome: it can be expressed as a range of heart disease and large vascular disease is a congenital disorder determined by the genes. U.S. women's volleyball national team of the famous spiker Hyman and Zhu Gang is a volleyball player died of the disease.

preventive measures:

effective way to prevent sudden death in moderate exercise, that moderate exercise on how to find their own

1,Discount UGG boots, to identify potential root cause:

(1) Charles family history: we can see if there is danger of genetic factors.

a student movement in Northern sudden death last year, Professor Sun Biao investigation found that his grandfather while his father was just a sudden death from heart disease at birth; and his father died of heart attack and is also early died.

have selected athletes, like the pick as tall as the arm length Hyman, however, in patients with Marfan syndrome, the typical body features, is the (toe).

Russian pairs genius Xieergaige Cove, U.S. basketball star Recchi Lewis, 汉克盖特斯, are also die due to abnormal heart development arena, they are associated with congenital disease factors.

(2) physical examination: weight check in the movement in the cardiac risk index.

A, check heart function index: sudden death in the majority of sports have heart disease, a normal physical examination of these hard to find, so the best comprehensive inspection of cardiopulmonary function.

B, check blood biochemical parameters: see the stationary state Gao Bugao blood viscosity, cholesterol Gao Bugao, see if it is at high risk of coronary heart disease.

C, physical fitness test: look up vital capacity, said weighing, measuring about flexibility, grip size, look for what kind of exercise.

D, exercise stress test: doing lay on hold, treadmill running and running, causing a certain amount of exercise load, tracking and monitoring, to see movement in the heart rate, ECG, lactic acid and other changes, which determine the best exercise load (heart rate can be expressed.)

lactic acid is produced during muscle movement of a metabolite, if you exercise, your lactate 4-5 mmol over, or even more, it shows you the amount of aerobic exercise than the safety line, and may be risk.

2, developed two kinds of people

exercise prescription exercise prescription for special needs.

(1) school students:

in schools, physical education teacher should be the physical condition of students, physical health to be a thorough investigation, especially for freshmen.

(2) first movement:

Jan Malm, President of Ericsson is not very good health, friends urged him to fitness, he thought, no activity for so many years, it ran running it, then bought a treadmill, the results of the die on a treadmill.

this case, not to say that sports is not good, but that long-term people who do not engage in exercise, sports and fitness in the to, be sure to look up the body have disease problems, be sure to open a scientific exercise prescription.

moderate exercise: a comfortable happy

1, movement preparation before and taboos

(1) for activities: a small white-collar workers want to exercise every day Palou work, he discovered a strange phenomenon, if he was walking to the unit, and then when you climb it more than a dozen floors, crawl spaces in the first, do not feel tired; but if you drive to the units, climbing to three or four floors of the gas exhausted blow out.

This phenomenon indicates that , although this time the amount of exercise as usual, but that did not prepare your heart, it is

(2) from overwork: Jan Malm Ericsson executives to work overload day, has let his heart can not bear, and then work on the treadmill running, the heart of nature is more unbearable.

Therefore, those who like to exercise after work, and if physically and mentally very tired, exercise must be a preparatory activities before the adjustment, and then from slow to fast moving.

If excessive fatigue, physical fitness did not reach normal levels, according to exercise prescription can not do it, but to reduce the amount of exercise in due course.

(3) influenza illness: some cold, to exercise, like a disease that came from Khan, this is very dangerous.

study found that people do strenuous exercise, the immune system will decline. Have decreased immunity to illness, and do strenuous exercise, immune system decline further. Myocardial flu virus pro features dual resistance decreased, so that free virus can be drilled, myocardial infection, suffering from viral myocarditis.

2, the movement fun

movement, how to find their own movement is not excessive? Professor Sun Biao, a summary of formulas: muscles have been stretched, breathing can talk heart beat Huan, body slightly sweating.





Professor Sun Biao healthy adults as a formula: 170 beats / min - age = heart rate control during exercise. If you are 30 years of age, then you run up, the beats per minute less than 140 times, is normal, this running speed, is appropriate.

purposes. Only the body sweating slightly, the amount of exercise that you just did exactly.

3,

feel comfortable after exercise to see your fitness does not moderate amount of exercise, after exercise depends on the response, Professor Sun Biao has a pithy formula: body blinded, sleep sleep intoxicated, slow heart rate get up, the spirit is very full.

If the body is sore, too much of is exercise. Rest of the night, metabolites not removed, it was sore.

excessive movement, and so sympathetic too excited and difficult to suppress.

Daily eyes eyes opened, and the first check pulse, if you exercise for, you'll see the number of daily check of the pulse gradually decline, such as, pumping out a certain amount of blood, the original need to jump 70 times, and now jump 68 times on the line, this indicates that your heart function has improved in the movement; However, if the stroke fluctuated morning, not a law, it only shows too much of your campaign, so that the heart can not meet.



emergency rescue: Gold 4 minutes

1, attention is not performance:

movement may occur in chest tightness, shortness of breath, palpitation, headache, nausea, etc., do not few people thought it was a normal reaction during exercise, ignore it and continue to exercise, or even that this is their own do not exercise enough,UGG boots, lead to physical deterioration, more determined to continue to exercise, increase the amount of exercise the faith that is very dangerous.

2, race against time to rescue:

8 minutes people will die.

So, if you find someone in the movement suddenly collapsed to the ground, should immediately be supine, hand-to-the carotid artery, Ruoyi no arterial pulse, CPR should be immediate treatment.

rescue, first head back to the patient airway smooth and effective chest compressions, mouth resuscitation at the same time, until professional emergency personnel to the scene. If the light hit 120,UGG boots clearance, this life laid to rest!
