It determines the minimum permissible frequency of physical exercise

British scientists have determined the minimum allowable, as recommended by WHO (World Health Organization), the frequency of exercise. Dedicated to this study published in the journal JAMA Internal Medicine, briefly about it informs EurekAlert!

Experts have established that the implementation of the WHO-recommended once weekly norm of physical activity is sufficient for the prevention of premature death, as well as provoking its offensive cardiovascular disease and cancer.

By its conclusions scientists came after a meta-analysis of studies carried out in 1994-2012 years. These materials included information on physical activity more than 63500 respondents from England and Scotland, whose average age was about 59 years old.

Among these people died tysyach about 14.1 including thousands of 2.8 - cardiovascular diseases and 2.5 thousands - of cancer. The study found that the risk of premature death in the life of those who engaged in physical activity at least once a week, on average, 30 percent lower compared with inactive people.

The study involved mostly white population of England and Scotland, and the write performance of physical activity were based on self-assessments of the respondents. Previously, scientists believed that the WHO recommended weekly load to be distributed evenly on at least three for during this period.

Recommended minimum WHO standards of physical activity needed for the prevention of stroke, diabetes, cardiovascular disease, and breast and colon cancer, are 600 MET-minutes. This is equal to brisk walking for 150 minutes or run for 75 minutes.

Published in the summer 2016 study by American and Australian scientists found that the WHO recommended figure should be increased to five to seven times.
Parameter MET (Metabolic Equivalent of Task, metabolic equivalent) is the ratio of the level of human metabolism during physical activity to the level of its metabolism at rest.

It is known that compared with the resting state burns moderately active person in three to six times more calories (six three-MET) and highly active people - more than six times.
