A new study continues a long list of positive effects of physical education.
Only 20 minutes of exercise is enough to suppress inflammatory processes at the cellular level.
This is reported by Brain, Behavior and Immunity.
The long-term benefits of physical activity are generally recognized.
Exercise protects us from cardiovascular diseases, normalizes metabolism and struggles with obesity, strengthens the musculoskeletal system, improves mood.
A group of scientists from their University of California in San Diego under the direction of Dr. Suzi Hong (Suzi Hong) has proved that under the influence of physical exercises, the production of pro-inflammatory substances decreases.
According to Dr. Hong, an employee of the Department of Family Medicine and Public Health UCSD, the effect is mediated by the sympathetic nervous system.
As is known, the sympathetic nervous system is responsible for increasing the pulse, blood pressure and respiratory rate. Physical exercises activate this department of the nervous system, forcing the body to work more intensively.
During the load, more adrenaline and noradrenaline hormones are released that act on the adrenergic receptors of immune cells.
The immune response to exercise.
The discovery of American scientists is impressive. Only 20 minutes of intensive exercise was enough to suppress the production of inflammatory cytokines - protein substances produced by immune cells.
It's about monocytes - a variety of white blood cells that are needed to fight infections. Their cytokines include TNF (tumor necrosis factor).
TNF not only participates in protective inflammatory mechanisms, but also causes cellular death. In injuries, infections, life-threatening situations, inflammation is necessary, but a chronic inflammatory process is associated with serious diseases, including diabetes, fibromyalgia, arthritis.
To test their hypothesis, the scientists asked 47 healthy volunteers to work on the stationary bike for 20 minutes with an intensity corresponding to their level of preparation. Before and after the test, participants submitted a blood test for markers of inflammation.
The 20-minute load was enough to reduce the level of inflammation.
This confirmed the hypothesis of Dr. Hong: exercise reduces the production of pro-inflammatory cytokines in immune cells.
"Although the anti-inflammatory effects of physical exercise are known to science for a long time, we were able to explain this phenomenon more deeply. This opens up completely new methods of treating chronic inflammatory diseases, which affects 25 million US residents and hundreds of millions around the world, "Hong said in a statement..
The new discovery will help millions of people with limited strength and mobility who are sure that positive effects require exorbitant loads for them. In fact, there will be enough effort and success will come.
"Our study confirmed that for health it is not necessary to spend hours simulators, clenched teeth. Sufficient 20-30 minutes of moderate intensity classes, including fast walking or biking. The physical load should be such that you breathe in full breast, and the pulse was slightly accelerated, "- the authors specify..
