Does running slowly worsen varicose veins on legs?

No: This activity has no effect on the varicose veins. Wear support stockings and if concerned, see your pcp for advise on further options. Don't stop exercising unless it is just too uncomfortable.

No: Varicose veins in the legs are caused by valvular disruption in the superfical veins, dvts, or deep vein insufficiency. ( their must be increased pressure in the veins for varicosities to form) running slowly has no effect. I do see alot of athelets get varicose veins in their calves however. So there may be some correlation between varicosites and atheletes but not running slowly.

More prominent: As dr. Mountcastle said, there may be a posssibility that running can slowly worsen varicose veins on your legs. Often runners have slender legs with very little subcutaneous tissue. As a result, the veins on runners' legs can be more visible and sometimes look like they are varicose but, in actuality, they are completely normal.

VV and exercise: Varicose veins are due to malfunctioning (refluxing) valves of the saphenous system. Contraction of the calf muscles increases the venous return to reduce the venous hypertension and this is good for the veins. Running, however, because of the jarring and pounding of the legs on the ground can actually worsen varicose veins by the increased pressure on the valves. Non pounding exercise is best.

Varicose veins: running is not a problem and the speed has no bearing however increased aerobic activity can cause the veins to work harder so use of a support or compression stocking after ta aid in recovery would be beneficial

No: The speed of running does not make a difference. Any exercise will help the venous circulation of the legs regardless of the speed.

Yes, running worsens: Running can damage weak one way valves within leg veins, worsening varicose veins. It is not how fast you run but how hard you slam your foot down. This generates tremendous torque on the valves, leading to damage and failure, the veins subsequently dilate. Walking is much more beneficial.

Not the speed: As drs. Farhy and presant said, pounding, more than speed, might have an influence on your veins and make them worse. Low impact exercise (biking, walking, swimming, etc.) is likely better. The most important thing though is that you exercise, regardless of what you do.
