Performing “toe raises” or calf flexing exercises is one method that has long been recommended as a way to promote blood flow in the legs in order to reduce the risk of developing blood clots in the legs (deep vein thrombosis or DVT) while on long flights. More recently some have voiced concerns about a similar risk for those of us who sit for long periods of time at our computers. To be honest, I try to do calf flexor exercises when working at my computer; but if I’m working intently, it simply is hard to remember to do so. An individual in the United Kingdom recently designed a sort of shoe that may help with this issue. The shoe has a curved bottom to facilitate such calf flexor exercises. You can learn more about these devices at http://www.calf-flexors.com/index.html I’ve been told that a large, international pharmacy chain is interested in bringing these devices to market in the U.S. While these devices would seem to be a good way to promote more exercise to increase circulation while sitting for long periods of time, I must admit that I am not aware of scientific data to prove this hypothesis or to confirm that use of the devices actually has the desired effect. But the concept certainly seems logical.
