Each year in the U.S., more 100,000 people are diagnosed with colon cancer. To see what effect exercise has on lowering this rate, researchers at Washington University and Harvard University combined to review 52 studies over the last 25 years which linked exercise and the incidence of cancer. Overall, they found that those that exercised the most (5-6 hours of brisk walking per week) were 24 percent less likely to develop the disease than those that exercised the least (less than 30 minutes per week).
"The beneficial effect of exercise holds across all sorts of activities," said lead study author Kathleen Y. Wolin, Sc.D. of Washington University. "And it holds for both men and women. There is an ever-growing body of evidence that the behavior choices we make affect our cancer risk. Physical activity is at the top of the list of ways that you can reduce your risk of colon cancer."
So, are there any studies out there that link exercise with a negative outcome?
In a recent study published in the journal Obesity, Dolores AlbarracĂn, professor of psychology at the University of Illinois, did find that people who are shown posters with messages like "join a gym" or "take a walk" actually ate more after viewing these messages than those that saw messages like "make friends."
"Viewers of the exercise messages ate significantly more (than their peers, who viewed other types of messages)," AlbarracĂn said. "They ate one-third more when exposed to the exercise ads."
The designation of ``Key School'' exists for selected schools at every educational level in China: elementary, secondary and higher. In addition, there are various levels of the ``key'' designation itself: There are national key institutions, provincial or municipal key institutions, and county or district key institutions. Key schools all enjoy priority funding as well as the privilege of recruiting the best students. At the elementary and secondary levels, this concept is similar to that of a ``magnet'' or ``college preparatory'' school in the United States. Entry into such schools is based on examination and academic promise and achievement. For such schools, success is usually measured in terms of the percentage of its graduates entering colleges and universities, especially the key colleges and universities. The philosophy has been that giving a limited number of schools, colleges and universities priority in allocating limited resources, then the t...
