Why sedentary lifestyle is harmful for the heart
Health / / December 19, 2019
The more time you spend immobile, the more likely to make heart muscle damage.
Those who sit on the day of 9-10 hours (the majority of office employees) are at risk to make diabetes and heart problems. And the risk is almost not reduced, even if you exercise. Scientists came to this conclusion.
Immobility long been associated with heart failure. In this disease, the heart gradually weakens and can not pump the required amount of blood. As a result, the cells are not fed enough oxygen.
To understand how a sedentary lifestyle is associated with heart disease, cardiologists at the Medical Center of the University of Texas studied the proteins troponinsSedentary Behavior and Subclinical Cardiac Injury. This marker of myocardial damage: for example, a huge amount of troponin is released into the blood during heart attack.
Even slightly elevated levels of these proteins causes concern of cardiologists, if a long time is not reduced. A chronically elevated levels indicates damage to the heart muscle. If nothing is done, may develop heart failure. Cardiologist Philippe Kuzmenko, author Telegram-channel "
Dr. Phil"I talked about what she's dangerous.Chronic heart failure seriously reduces the quality (people have a shortness of breath and swelling in the legs), and life expectancy. Without addressing the cause of the heart failure, the outcome is almost always a foregone conclusion - a sudden death.
Philip Kuzmenko, physician, cardiologist and university lecturer.
Scientists have analyzed the results of a large cardiology researchThe Dallas Heart Study using the probability sample technique for ethnicity and cardiovascular health differences. They reviewed the ECG, blood tests and physical activity data trackers over 1700 healthy participants. Particular attention was paid to the troponin levels in the blood and evidence of activity trackers.
It turned out, many of the participants spend sitting more than 10 hours a day and rarely participate in sports. Basically their limited physical activity walking. They also noted elevated levels of troponin. Of course, it was much lower than that of a heart attack, but nevertheless it indicates latent myocardial damage.
The researchers tested other factors that could affect the level of troponin: age, sex, body mass index, heart condition. But the relationship with the fixed way of life was expressed most strongly.
Philip KuzmenkoAll systems of the body sharpened by the motor activity, because our ancestors did not sit in the office and running after prey or in order to avoid becoming prey themselves. Therefore, a sedentary job is a serious risk factor for heart disease and, as a consequence of chronic heart failure.
Scientists can not yet explain exactly how sedentary hurts muscle heart cells. According to the head of research, cardiologist James de Lemos (James de Lemos), it affects the heart indirectly. "Immobility is associated with obesity, diabetes and the deposition of fat in the heart. All this can lead to damage to the heart muscle, "- he says.
And it is important not only to sit less, but also to move more. Although not found a significant impact on the sport level of troponin, de Lemos advises to move as much as possible. Go up and down the stairs, leave your car at the far end of the parking, standing or hold meetings on the go.
Philip KuzmenkoA man who works in the office, it is necessary not less than 2 hours a day to walk; every hour during the working day to get up from the table and do a 3-5 minute warm-up (sit-ups, body rotation, stretching); cardio hold (in the absence of contraindications), 3-4 times a week.
