More out of Running with Compression Socks

Compression socks are one of the latest running trends that have been seen lately on some elite runners and tri-athletes, but also are becoming more popular with even the casual runner seeking an edge.  These socks, originally created for diabetics to help improve circulation, are now being used to do the same for runners and triathletes to decrease fatigue and leg cramps. 

How They Work

These socks use compression to counteract the results of gravity that causes blood to pool in the lower legs and feet, which can cause fatigue or cramping.  The compression socks use stronger elastics to create pressure to the calves, ankles and feet.  The compression is tighter at the ankle and gradually less moving up the leg toward the knee. The pressure causes the blood to return to the heart and less blood to pool in the feet. This forces de-oxygenated blood out and replaces it with oxygenated blood.  The oxygenated blood is what runners believe will make them run and recover faster. 

But Do They Work?

Running legends such as Paula Radcliff and other world class athletes promote the benefits, which include better circulation and oxygen to the muscles, quicker recovery through faster lactic acid removal, increased endurance, reduced cramping, and less muscle fatigue. 

Although substantiated studies on the benefits of compression socks to runners and triathletes have been inconclusive, many believe they work.  One study by the American College of Sports Medicine did support a faster lactic recovery rate following exercise with treadmill runners wearing compression socks.

The lack of validation in studies does not deter those who swear by them.  For those who have tried them, the only complaint noted was that in the heat of the summer, they can get itchy and hot, just as you would if you wore running tights in the summer.  But it may be worth it for the added benefit of greater muscle efficiency and shorter recovery, especially on strenuous workouts.
