More than 7000 steps a day reduce the risk of cancer – Diepresse.com
US scientists found that 7,000 to 9,000 steps a day significantly reduce the risk of developing cancer.
Around 7,000 steps completed a day can be demonstrated by a protective effect against cancer through everyday physical activities. This is the result of a US study with around 85,000 British subjects in the middle age of 63. Alaina Shreves from the National US Cancer Institute (NCI/Bethesda in the US state of Maryland) and its co-authors from Great Britain and Portugal have analyzed the data from UK BioBank.
It was evaluated after the physical activity in the context of everyday life, not for sporting activities. The subjects were 85,394 people aged around 63 years. They had all worn an accelerometer for measuring their physical activities for a week when joining the study. The observation period for the occurrence of cancer was 5.8 years. Until the evaluation, a malignant disease had been diagnosed in 2633 people.
Plateau effect from 9000 steps
In the context of the analysis, it was clearly dependent on the frequency of disease on the extent of physical activities in everyday life. It was about « normal » activities such as shopping, activity in the household etc. « An effect was detectable from about 7,000 steps. These people were eleven percent less frequent (note; note) than with a daily step of 5000. With an increase from 7000 to 9,000 steps a day, the risk dropped again by 16 percent, » wrote the German medical leaf again.
Another important result, according to the scientists in the British Journal of Sports Medicine: « The number of steps back daily showed an inverse correlation to cancer. This dose dependency began to reach a plateau from about 9,000 steps a day. » More movement in everyday life beyond this extent no longer showed any additional preventive effect.
How this works is not yet clear. For example, a reduction in estrogen and growth factor levels in the blood are suspected. Physical activity also reduces insulin levels. This metabolic hormone is also associated with cancer. Less body weight in turn dampens subliminal inflammatory reactions that are suspected of promoting many diseases in the long term, such as cardiovascular disorders by atherosclerosis. (APA)
