In the new study, Homme, assistant professor of nutrition and exercise physiology at the University of Missouri School of medicine? Dr. Padilla and his colleagues conducted a comparative analysis of the vascular function of 11 healthy men before and after sitting for a long time. The results showed that after sitting at the desk for 6 hours, the blood flow of the popliteal artery (calf artery) of the participants was greatly reduced. When the participants walked for a short time, it was found that 10 minutes of random walking could restore blood vessel function and improve blood flow speed.
According to Dr. Padilla’s analysis, sitting for a long time will inevitably lead to reduced blood flow in the legs. This will lead to a decrease in the friction force of the arterial wall and the ability of blood vessel expansion. The expansion ability is an important sign of the health of blood vessels. The stronger the expansion, the healthier the blood vessels will be. Ergonomic experts also warn that standing for a long time can also lead to carotid artery disease, varicose veins and other diseases, and problems can also occur in the back and feet. Alan, Professor of ergonomics at Cornell University in the United States? Dr. Heji suggested that every 90 minutes of work, office workers should stand up for 8 minutes, walk and stretch for 2 minutes.
