According to a large study, a healthy cardiorespiratory fitness level at a young age with up to a 40% reduced risk of 9 certain types of cancer is related at a later point in time, the cancer of the lungs, intestines, head and neck, kidney and kidney contains. Liver, pancreas, stomach and esophagus.
Cardiorspiratory fitness (CRF) describes the ability of a person to carry out aerobic exercises, including swimming, cycling, running or even climbing stairs for sustainable periods. It is associated as a reduction in the risk of specific cancer, but not many long -term studies of several types of cancer have not been documented.
The researchers used related data from the Swedish register in which medical diagnoses, background information and deaths were treated by participants until the end of 2019.
At the beginning of the study, when the participants were between 16 and 25 years old, they were subjected to a standard array of measurements. This included CRF, muscle strength, blood pressure, BMI and height.
Participants with a low CRF mirror more often had a substance and alcohol abuse history and were a little obese compared to participants with a higher CRF level.
A total of 365,874 participants, all male, low CRF values; 519,652 had moderate CRF mirrors; and 340,952 had high CRF values.
The final analysis comprised over a million men, 7% of whom cancer developed for an average of 33 years in at least 1 location in 33 years of surveillance.
Compared to men who have a low fitness level at the beginning of the study, higher CRF linear was associated with a reduced risk of developing certain types of cancer.
It was 5% associated with a reduction in rectal cancer risk. a reduction in pancreas cancer risk by 12%; a reduction in colon cancer risk by 18%; a 19% reduction in head and neck cancer risk; a 20% reduction in kidney cancer risk; a reduction in gastric cancer risk by 21%; a reduction in the risk of esophageal cancer by 39%; a reduction in liver cancer risk by 40%; And a 42% reduction in lung cancer risk.
However, a higher CRF was also 31% associated with an increase in prostate cancer risk by 7% and an increase in skin cancer risk. The researchers suggest that screening on prostate cancer and sunlight could be the reason for these results.
Since it was an observation study, no clear conclusions with regard to cause and effect can be drawn, and complete data on other lifestyle risk factors that could have influenced the results were not available, including smoking, alcohol consumption and nutrition.
The researchers were also unable to monitor CRF changes over time or collect genetic data on the participants.
