爲什麼一整天都坐着看電視是最危險的事情之一

Prolonged periods of sitting and watching television causes a THREE-FOLD increased risk of developing a walking difficulty in later life, a new study has shown. The study, which followed a group of healthy people between the ages of 50 and 71 for 10 years, found that prolonged sitting was particularly harmful when combined with low levels of physical activity.

一項新研究表明：長時間坐着看電視會導致以後走路困難的風險增加三倍。該研究對50歲至71歲的一組身體健康人士隨訪了10年，研究發現身體活動較低時，長時間的坐着尤爲有害。

Participants who watched 5 or more hours of TV per day had a 65% greater risk of reporting a mobility disability at the study's end, compared with those who watched the least amounts of TV (less than 2 hours per day) - regardless of their level of physical activity.

研究結束時，相比看電視最少的人（每天少於2小時），每天看電視5小時或以上的受試者行動障礙的風險要高65%--無論他們的身體活動水平如何。

However, those who had 3 hours per week or less of physical activity were found to be even more likely to have difficulty walking by the end of the study. "Sitting and watching TV for long periods (especially in the evening) has got to be one of the most dangerous things that older people can do," said Professor Loretta DiPietro, lead author of the study from George Washington University in Washington, DC.

然而，研究結束時，那些每週只鍛鍊3小時或更少時間的人被發現更有可能走路困難。"長時間坐着看電視（尤其是晚上）是老年人能做的最危險的事情之一，"該研究的主要作者洛麗塔·迪彼得羅教授說道，她來自於華盛頓特區喬治華盛頓大學。

This study comes a week after Public Health England announced the country is facing a shocking health time-bomb due to inactivity. The survey showed that more than six million middle-aged Brits fail to manage a single brisk 10 minute walk in a month.

英格蘭公共衛生局宣佈該國國人由於不運動而面臨着令人震驚的健康時間炸彈消息一週後，該研究問世。調查顯示：600多萬中年英國人一個月都未能快走10分鐘。

"As we age, the less we use our muscles, the worse they become in terms of quantity AND quality," said Dr James Brown from Aston University and trustee of the British Society for Research on Ageing.

"當年紀越來越大，我們使用肌肉的頻率也越來越低，因此肌肉的數量和質量都變得更差，"英國老年研究協會的受託人和阿斯頓大學的詹姆斯·布朗博士說道。

"The key message is USE IT OR LOSE IT!" Dr Brown told the Daily Mirror.

"關鍵信息就是不使用肌肉你就會失去肌肉！"布朗博士對Daily Mirror期刊說道。

benefits of walking

走路的好處

The minimum recommended amount of exercise is ten minutes walking at brisk intensity every day. This benefits inactive adults the most as it gets the heart pumping in order to improve health.

每天最低的推薦運動量就是10分鐘的快走。這對平時不動的成年人最爲有益，因爲快走能讓你撲通撲通的心跳，從而改善健康。

Research shows that anyone completing that would be 15% less likely to have an early death, 40% less likely to develop Type 2 diabetes, 35% less likely to suffer heart problems and 30% less likely to get dementia.

研究表明：每天快走10分鐘的人早死的可能性要低15%，患2型糖尿病的風險要低40%，患心臟疾病的風險要低35%，而癡呆的可能性要低30%。
