Yesterday's post discussed fitness and healthy aging. Today's post further illuminates why exercise is so important.
Researchers at the Siteman Cancer Center in St. Louis compared the physical activity of more than 150,000 men and women, using reports gathered between 1982 and 1997. The investigative team then correlated these activity levels with cancer diagnoses between 1998 and 2005, and with cancer deaths between 1998 and 2006. They found that those who exercised on a daily or near daily basis for at least 10 years had the lowest risk of dying from colon cancer. Meanwhile, researchers at the Harvard School of Public Health and the University of California, San Francisco, studied the exercise habits of 2,705 men diagnosed with prostate cancer over an 18 year period. The data suggested that those who walked 90 or more minutes per week at a normal to very brisk pace had a 46 percent lower risk of dying from any cause compared to those who walked less than 90 minutes per week at an easy pace. In this study, more than three hours a week of vigorous activity was associated with a 61 percent lower risk of prostate cancer death compared with men who did less than one hour a week of vigorous activity.
