Sport plays a major role in health. It helps prevent and even treat most diseases. It burns calories, increases muscle mass, that tissue that, along with the brain, uses the most energy. Sport leads to the multiplication of mitochondria. These are the mini-power plants of our cells that provide the energy necessary for the multiplication of antibodies and white blood cells. In this way they form a bulwark against inflammation.
When our muscles are contracted, burning sugar lowers glucose by pulling it into cells by osmosis. This powerful hypoglycemic effect makes physical activity THE first drug for diabetes. The Finnish FDPPS study shows that in people who are overweight and have glucose intolerance, the risk of type II diabetes is reduced by 58% in the group who exercise daily.
Sport has cardio-protective effectss
Endurance sports or aerobic sports have not only cardio-protective but also therapeutic effects. Where in the past people who had just had a heart attack were kept bedridden, nowadays they are called up very quickly after their accident. It’s simple, exercise strengthens the heart and helps dilate blood vessels.
For example, of the 1,104 firefighters followed by a team from Harvard University between 2000 and 2010, those who were able to perform at least 40 push-ups at a specified frequency had a 96% lower risk of developing heart disease in ten years compared to those who could only perform ten or less. And people who regularly work on their endurance (brisk walking, running, cycling, cross-country skiing) have a lower resting heart rate than untrained people. A slower heart through sport would thus contribute to extending our lifespan. Sport also improves the quality of sleep, the period in which our energy maintains: anti-infective defenses, detoxification, evacuation of pathogenic proteins, DNA repair…

benefits against cancer
Sport is a very important part of cancer prevention and treatment. Intense physical exertion causes hormesis, the function of which is the neutralization of carcinogens,
reducing mutations and the emergence of cancer cells. When cells become cancerous, they consume a large amount of glucose for energy.
On the contrary, a lack of glucose can weaken their functioning or even lead to suicide, as shown by the team led by Serge Manié from the Center for Cancer Research in Lyon. The more a cancer patient contracts his muscles during the day, the more sugar he steals from his tumor.
Sports with pressure prevents the reduction of muscle mass. Between the ages of 30 and 80, we lose on average a third of our muscles. But the muscle is important to maintain its ability to move, to prevent falls and fractures. It also provides our glutamine capital, this amino acid that participates in the production of our tissue proteins and is a privileged fuel for white blood cells.

A known anti-stress and antidepressant factor
Many studies show that as an antidepressant, sports have a longer-lasting effect than drugs. Sport also serves as a sensory distraction from hypermentalization and rumination and improves self-esteem.
It is a basic neuroprotector. Six months of physical activity in healthy people is followed by increased volumes of the hippocampus and other brain regions on brain imaging. A meta-analysis of sixteen studies involving 163,797 people shows that regular exercise reduces the risk of dementia
28% and Alzheimer’s disease 45%. Moving every day is therefore a cheap polydrug that pays off a lot.
