We know the benefits of physical activity on weight and health. A study by Danish researchers shows that a good physical condition also reduces the risk of inflammation and inflammatory disease.
Moving is good for your health! The benefits of physical activity are known and recognized. Being in good physical condition can be healthier. On the other hand, having "bide" or "brioche" is really bad.
A study done at the University of Copenhagen in Denmark shows that poor physical condition is associated, of course with too much waist circumference, but also with a higher risk of inflammation. The results were published this week in the journal PLOS One.
Fat secretes inflammation proteins
Many studies have shown that excess fat in the belly (visceral fat) can increase the risk of chronic inflammation and metabolic disorders (metabolic syndrome). This risk is related to a secretion by the intra-abdominal fat of pro-inflammatory proteins: the "adipokines".
In this new study, researchers found that fitness level is also inversely proportional to abdominal fat and waist circumference, as well as to inflammation level.
A wide study and reliable criteria
Scientists analyzed data from 10,976 people. To assess their fitness, they were tested for VO2 max, the test in use that calculates the maximum amount of oxygen an individual can consume during physical activity. It is calculated per unit of time. The person's waist circumference was measured, as well as their weight, blood tests were also performed to determine the level of C-reactive protein.
The researchers found that people with good physical condition had a smaller waist, and less inflammation, and this without a direct link to their body mass index. The body mass index is indeed, quite poorly correlated to the waist: you can be a little fat but have a very big belly, or be obese and have mostly big buttocks!
Inflammation related to abdominal fat
Several studies have shown in recent years that pro-inflammatory proteins that are secreted by fat inside the belly and belly organs are responsible for general inflammation and worsening autoimmune diseases.
For example, in osteoarthritis, adipokines are associated with more aggressive hand osteoarthritis in obese patients, whereas it is quite rare to see an obese walk on the hands! The overload of the joints can not be evoked. Similarly, in rheumatoid arthritis and spondyloarthritis, these autoimmune diseases are more severe in obese patients and treatments, even the most powerful, are less effective.
To be in shape and avoid inflammatory diseases, walk, run, pedal or swim, but the main thing is to move!
