Does fitness really lead to varicose veins?

Under normal circumstances, proper muscle activity is of course beneficial to venous blood return. However, if all sports are competitive, then high-intensity training, weight-bearing or competition will make muscles try their best to contract for a long time, and when muscles contract, they can squeeze blood from veins into the heart. When muscles relax, the pressure in veins decreases, which is beneficial for blood in veins and capillaries to flow into veins and fill them.

But frequent muscle contraction for a long time will affect the filling and reflux of veins. In addition, long-term exertion will increase abdominal pressure, and it will also lead to the damage of venous valves of lower limbs, increase the burden of blood reflux, and eventually lead to venous dysfunction, blood reflux and varicose veins of lower limbs.

Therefore, athletes should relax and rest moderately after high-intensity training, so that the muscles that have been in a state of tension for a long time can be properly stretched and the blood flow can be smoother. Therefore, the prevention of varicose veins should not be blind exercise, gentle exercise is more appropriate, and high-intensity and intense exercise is best not to be carried out for a long time.
