I posted about this three years ago, in my old blog, www.ultranewby.blogspot.com after two of my runner friends developed DVT's-blood clots.
It's still a good read. And read the comments that other athletes left, about their experiences.
Yes, I want to scare you. A bit. OR actually, I just want you to be aware.
You think of blood clots in ..old people. You don't think about ultra runners, or triathletes, being the ones who who develop these blood clots.
Yet we are prime candidates for these.
Okay, Athletes tend to
have a lower resting heart rate. This results in blood flowing slower
through the body.
Dehydration-this plays a factor in your blood viscosity. More dehydration leads to thicker blood.
Falls, bruises? Nah, this never happens in an ultra. (Non runners would
call this "trauma") Ultra runners? Well, we took a face plant eight
hours ago. No big deal, right? I got a little banged up. Got some bruises on my quads, knee, arm. No big deal.
Due to this
trauma, there may be a clot forming at the spot in the cell wall. This
is your body functioning normally.
After the race is over, we get
into our car, or onto an airplane, and travel hours back to where we
came from. We spend hours in a cramped position.
thickened blood is pooling.The body is still dehydrated. The body is
forced into the worst position to get the blood pumping throughout the
body again. This is where the start of a clot in the legs (in the deep
veins) can begin.
Why I am posting this again?
Well, another well known ultra runner, Amy Sproston, had posted to the Ultra List about her diagnosis with DVT's. Amy is an elite runner AND spends many hours in the air with her career. It didn't seem like her DVT developed post-race, but maybe due to her air travel.
She had a pretty scary weekend, according to her blog post, where the DVT went from the DVT to a PE (pulmonary embolism). She did go to the Emergency Room, and got admitted, and treated. Amy is still hoping/planning on going to the Worlds 100K Race.
So take ten minutes, and read through some of this. And think about your post-race plans. If they involve plane travel, think about compression stockings. Stop more often on the road for a rest break. Hydrate hydrate hydrate!
