Even regular exercise cannot fully neutralize the negative effects of prolonged sitting on the blood vessels in the legs, according to researchers from Dalhousie University, as reported by infohub.kz.
In the experiment, which involved 21 young healthy individuals, volunteers were divided into two groups. The first group performed a high-intensity interval training program for 12 weeks, while the second maintained their usual level of activity. Before and after the exercise period, participants underwent cycling tests to assess aerobic fitness.
Using ultrasound, the researchers evaluated the condition of the popliteal artery before and after participants sat continuously for two hours. They found that despite improved overall endurance in the trained group, their blood vessels suffered from prolonged sitting just as much as those in the control group. The artery's ability to relax and expand decreased to the same extent.
The authors emphasized that physical activity is crucial for cardiovascular health, but a high fitness level alone does not protect against the effects of a sedentary lifestyle. Experts recommend not limiting yourself to exercise during the day, but also regularly getting up from your desk and doing short stretching breaks.
