Why are this pro cyclists feet purple? Doesn't that indicate no circulation or oxygen?
It's a common sight in the world of professional cycling: riders with bright purple feet. But what causes this unusual discoloration? And is it a sign of poor circulation or oxygen deprivation?
The answer is no. Purple feet in cyclists are not caused by a lack of circulation or oxygen. In fact, it's quite the opposite. The purple color is caused by a phenomenon known as "reactive hyperemia."
When cyclists pedal hard, they put a lot of stress on their feet. This stress causes the blood vessels in the feet to dilate, which increases blood flow to the area. The increased blood flow helps to remove waste products and deliver oxygen to the muscles.
After a cyclist stops pedaling, the blood vessels in the feet constrict, which reduces blood flow to the area. This can cause the feet to turn purple. The purple color is usually temporary and will disappear within a few minutes.
So, while purple feet in cyclists may look a little unusual, they are not a cause for concern. They are simply a sign that the body is working hard to deliver oxygen and nutrients to the muscles.
