an international team of researchers found that expert recommended levels of physical activity reduce the risk of seven cancers.
Experts have studied the data of nine studies involving more than 755 thousand adults ranging in age from 32 years to 91 years. All participants reported on their physical activity.
the Average observation period for volunteers and collection of medical data was about ten years old. During this time the participants of the research there were more than 50 thousand cases of cancer.
Conducting meta-analysis, the researchers focused on how physical activity are associated with the likelihood of 15 of cancer.
it Should be clear that to train at a moderate or intensive experts advise from two and a half to five hours a week, and engage in other active activities, from a half to two and a half hours a week.
people who comply with these recommendations, there was a statistically significant reduction in the risk of development of seven types of cancer.
This is a cancer of the kidneys (the risk reduction ranged from 11% to 17%), myeloma (14-19%), liver cancer (18-27%). Additionally, men decreased the likelihood of developing colon cancer (8-14%), and in females breast cancer (6-10%) and endometrial cancer (10-18%) and non-Hodgkin’s lymphoma (11-18%).
Explain that in each case the first figures relate to those who are trained in accordance with the minimum norm, the second to those who are trained in accordance with the maximum recommended norm.
However, it is important to note the following. First, in these studies the authors relied on the answers of the volunteers and did not carry out measurements of the levels of their physical activity. Second, in the questionnaires the respondents reported physical activity in your free time. While not considered as they either walk or ride a bike, for example, from home to work and back.
However, the authors of the new study acknowledge that their relationship for meLSA as curious as they focused on recommendations for the prevention of cardiovascular disease and diabetes. Now you can say that the same advice is relevant for people who want to reduce the risk of developing cancer.
“Even a simple walk for 30 minutes on most days of the week can be important for cancer prevention,” said in an interview with Newsweek co-author ALPA Patel (Alpa Patel) from the American cancer society.
Scientific article on the results of her team is presented in the Journal of Clinical Oncology.
by the Way, earlier experiments on mice has helped to explain how physical activity slows down the growth of malignant tumors.
Also “Conduct.Science” (nauka.vesti.ru) told what workouts improve the lives of patients with breast cancer and could save patients with cancer against the negative effects of treatment.
