以自己的訓練程度量力而為,順著自己的節奏就對了.^^

其實是適不適當的問題吧~適當的話我覺得對身體應該是好的~~

Too many marathons can kill, warn doctors

Doing too many marathons could kill you, doctors have said in a stark warning about the dangers of taking too much vigorous exercise.

Fitness fanatics should do “just one or a few” marathons or full-distance triathlons, say the cardiologists, because over-exerting the heart for years can lead to long-term damage.

There is now convincing evidence that repeatedly asking the heart to pump “massive” volumes of blood, for hours at a time, can lead to an array of problems, they say.

醫生警告,跑太多的馬拉松會殺了你自己，
跑太多馬拉松會殺了你，醫生提出一個嚴重警告說太多劇烈運動會造成危險。

運動狂熱分子應該做的只是”跑一個或幾個“馬拉松或標準鐵人三項運動，心臟科醫師說，由於過度操勞多年的心臟，可導致長期的損害。

現在有令人信服的證據表明，反復要求心臟泵“龐大”的血量，一個小時的時間，可能會導致一系列問題。

These include overstretching of the organ’s chambers, thickening of its walls and changes to electrical signalling. These could trigger potentially dangerous heart rhythm problems.

“In addition, long-term excessive exercise may accelerate aging in the heart, as evidenced by increased coronary artery calcification, diastolic ventricular dysfunction, and large-artery wall stiffening,” they write in the journal Heart.

Dr James O’Keefe and Carl Lavie, from St Luke’s Mid America Heart Institute in Kansas City, and the Pennington Biomedical Research Centre in Baton Rouge, US, say the heart is only designed for “short bursts” of intense activity.

這些措施包括負擔過重的器官的房間，加厚的牆壁和電子信號的變化。這可能會引發潛在危險的心臟節律的問題。

“此外，長期過度運動可能會加速老化的心臟，增加冠狀動脈鈣化，心室舒張功能障礙，以及大的動脈壁硬化證明，”他們寫在日記心臟。

詹姆斯·奧基夫博士和卡爾·LAVIE，從聖盧克美國中部心臟研究所在堪薩斯城，並在巴吞魯日，美國彭寧頓生物醫學研究中心說，心臟是唯一專為“短脈衝”的劇烈活動。

 

They cite the example of Micah True, the hero of the book Born to Run about ultra-endurance running.

He died in March, aged 58, on a 12-mile training run in New Mexico. He routinely ran a marathon a day, sometimes more.

They believe that decades of such exertion led him to develop Phidippides cardiomyopathy.

Named after the original runner, who died delivering news of the Greeks’ victory at Marathon, it is “the constellation of cardiac pathology that has been in observed in the hearts of some veteran extreme endurance athletes”.

They concluded that most people should limit vigorous exercise to 30 to 50 minutes a day.

“If one really wants to do a marathon or full-distance triathlon etc, it may be best to do just one or a few and then proceed to safer and healthier exercise patterns,” they advise.

No amount light to moderate exercise is harmful, they note.

“A routine of moderate physical activity will add life to your years, as well as years to your life.

“In contrast, running too fast, too far, and for too many years may speed one’s progress towards the finish line of life.”

他們的結論是，大多數人應該限制劇烈運動30至50分鐘的時間。

他們特別註解:“沒有輕度或中度的運動是有害的”。

“一個常規的中度身體活動的生活增添你的年歲，以及你的生活。”

“相比之下，跑太快，太遠，太多年的衝向終點線的生活可能會加快自己跑至氣數放盡。”

 

Ellen Mason, senior cardiac nurse at the British Heart Foundation, said: “Whether you’re taking part in an endurance event, watching your weight or staying healthy after a heart attack, it’s important to build up your activity levels gradually, especially if you’ve not exercised in a while.”

埃倫·梅森,英國心臟基金會心臟科護，說： “無論你是參加耐力事件，注意你的體重或保持健康的心臟發作後，重要的是逐步建立你的活動水平(特別是如果你“有一段時間內沒運動了)。”

我總覺得，既然是肌肉，就可強化後再進化，變得更強韌，雖然訓練會受傷，但是只要適當休息，給予修復時間，重整後再練習，自然比之前更強。長時間跑步或高強度跑步會使心臟肌肉受損，引起心律不整，但是只要練習與休息配置得當，心臟應該也會變得更有韌性與張力。破而後立，只有打破原有界限，才能進化，唯有經過不斷的練習與配合調整休息，受傷會更輕微，需要的休息復原期會越來越短，所以許多連馬高手，跑完全馬身體依然通體舒暢，只要晚上睡個覺，就可以修復身體肌肉和心臟肌肉。隔天依然可以跑馬或自主練習，因為他們的身體肌肉或是心臟肌肉都比一般人更強，恢復週期更短，相信這些身經百戰的前輩，能夠變得這麼強，都是恆心、毅力與時間所累積的成果，千里之行無非均從腳下而起。

雖然那篇文章對我小有震撼，但我相信--人有很多無法解釋的可能

心臟學家：不宜常跑馬拉松

還好,我一年還跑不到十二場馬拉松,所以還不算常跑

 

所以,這個心臟學家應該先調查一下,跑百馬的前輩心臟好不好?

 

不然就調查一下,七十歲以上的馬拉松跑者,看他們的心臟好不好?

 

這些跑馬拉松的前輩,我最佩服的是他們的心臟有夠強

 

正常人心跳72下才夠,他們跳很少下就夠了
