有氧运动降低了13种癌症的风险

Comment: Exercise is also very important for cancer patients to fight against cancer.

Regular aerobic exercise is good for health.  On the contrary, a sedentary lifestyle can be very dangerous, leading to diseases such as obesity, diabetes and cardiovascular disease.  Simple fact is physical, mental, and emotional health can be improved through exercise.

And convincing evidence suggests that regular aerobic exercise can also help reduce the risk of many types of cancer.

For example, a meta-analysis of aggregated data shows that higher levels of physical activity and aerobic exercise can significantly reduce the cancer risk of at least 13 specific types of cancer.  For this study, researchers examined the medical history of nearly 1.5 million Americans and Europeans. The results showed that the risk for 13 out of the 26 cancers can be reduced by 10% to 42%.

More aerobic exercise equals more health benefits

A 42% reduction in the cancer risk was observed among subjects who exercised the most.  Exercise types include walking, strolling, jogging, running and other aerobic exercises. Those who did the most showed a 27% reduction in liver cancer risk and a 42% reduction in esophageal cancer risk.

The study was led by Dr. Steven Moore, Master of Public Health, of the National Cancer Institute in Bethesda, Maryland, and studied data came from a total of 1.4 million patients. In addition to liver and esophageal cancer, regular physical activity was associated with 20 to 26% reduced risk of other cancers including lung cancer, kidney cancer, stomach cancer, endometrial cancer and myeloid leukemia.

The health benefits of easy aerobic exercise should not be underestimated

Also physical exercise was linked to 13 to 17% reduced risk of   myeloma, colon cancer, head and neck cancer, rectal cancer and bladder cancer.   Research results show that people who participated in regular physical exercise had a 10% lower risk of breast cancer.   It has also been found that regular aerobic exercise can reduce the risk of cardiovascular disease, obesity and diabetes.   Being physical active also seems to increase life expectancy.

In short, higher activity levels seem to be associated with better health.  Specifically. walking 20 minutes a day can reduce the risk of many diseases, including cancer.   Regular exercise can also extend longevity and lifespan by seven years.  In contrast, lack of regular exercise has an even worse impact on health than obesity.

The take-home message is: Just 20 minutes of physical activity a day can get a huge health bonus. You also don’t need a gym or expensive equipment.  Walking is a type of a very beneficial aerobic exercise, and the health benefits of walking can save and improve your life.

评语：运动对癌症病人的抗癌也是很重要。

大多数人都知道定期有氧运动(aerobic exercise)有益于健康。相反，久坐的生活方式可能非常危险，导致肥胖(obesity)，糖尿病 (diabetes)和心血管疾病(cardiovascular disease)等疾病。简单的事实：身体(physical)，心理(mental)和情绪(emotional)健康都通过锻炼得到改善。

而且，现在，有令人信服的证据表明，定期有氧运动也有助于降低多种癌症的风险。

例如，最近对汇总数据的研究表明，更高水平的身体活动和有氧运动可以显着降低至少13种特定癌症类型的癌症风险。在这项研究中，对近150万美国人和欧洲人的病史和结果进行了检查。结果表明，所考虑的26种癌症中有13种癌症风险减低10％到42％。

更多的有氧运动等于更多的健康益处

42％的这一百分比范围的高端与行使最多的人相关。锻炼类型包括步行(walking)，散步(strolling)，慢跑(jogging)，跑步(running) 和其他有氧运动(aerobic exercise)。做得最多的人表现出肝癌(liver cancer) 风险下降27％，食道癌(esophageal cancer)风险下降42％。

该研究由马里兰州贝塞斯达国家癌症研究所的史蒂文·摩尔博士，公共卫生硕士领导，研究了来自总共140万患者的数据。除肝脏和食管癌外，其他与常规体力活动相关的癌症包括肺癌 (lung cancer)，肾癌(kidney cancer)，胃癌 (stomach cancer)，子宫内膜癌(endometrial cancer)和髓样白血病(myeloid leukemia)风险降低20％至26％。

轻松有氧运动对健康的好处不容小觑

此外，骨髓瘤 (myeloma)，结肠癌(colon cancer)，头颈癌(head and neck cancer)，直肠癌 (rectal cancer)和膀胱癌 (bladder cancer) 的癌症风险降低了13％至17％。研究结果显示，参与定期体育锻炼的人患乳腺癌 (breast cancer)的风险降低了10％。还发现定期有氧运动可以降低心血管疾病 (cardiovascular disease)，肥胖 (obesity)和糖尿病 (diabetes)的风险。另外，活跃似乎也延长了预期寿命(life expectancy)。

简而言之，较高的活动水平似乎与更好的健康相关。然而，已经发现每天步行20分钟可以降低包括癌症在内的许多疾病的风险。经常锻炼也可以使寿命 (longevity)和寿命 (lifespan)延长七年。相比之下，缺乏规律运动对健康的影响甚至比肥胖症更为不利。

要记住的主要信息：每天只需20分钟的体力活动就可以获得巨大的健康红利。您也不需要健身房或昂贵的设备;步行有资格作为非常有益的有氧运动，步行的健康益处可以挽救和改善您的生活。 （这不值得吗？）
