Sigvaris is a 150 year old Swiss company specialized in medical compression garments. They have been in medical compression for over 50 years. Medical compression garments are used for varicose veins, DVT, maternity, diabetes, leg ulcers, etc... In recent years compression garments and especially leg sleeves/socks and shorts have become popular in endurance sports.
Sigvaris says:
Athletes who wear SIGVARIS SPORTS products will benefit from:
- Increased circulation
- Improved blood flow through the veins- Increased oxygen to the muscle tissue
- Less lactic acid buildup in the legs during exercise
- Reduced exercise-induced muscle soreness in the legs
I have used a number of compression products over the last several years, primarily calf compression sleeves, including the first I found on the market CEP, then Zanesh, Salomon, SmartWool and more recently CEP again. While I am not sure about the performance benefits of improved circulation, improved blood flow and oxygen and less lactic acid build up I am pretty sure, that at least for me that with compression:
- I have less exercise induced soreness after wearing sleeves
- My legs feel more aligned in the direction of travel
- I am quite sure they help reduce calf cramps in long events by stabilizing the muscles, reducing vibration and preventing nerves from twitching into cramps. According to this article in Competitor quoting Prof. Schwellnus of the University of Cape Town “The mechanism for muscle fatigue and muscle damage causing cramping is best explained through an imbalance that develops in the nervous system control of muscle. Muscles tend to become very twitchy when they become fatigued or are injured,” said Schwellnus. "
