Paraplegics Can Cheat?!

How crazy is it that paraplegic athletes have found ways to hack biology to boost their performance?

The problem: They can’t sprint.


  • Their brains can’t tell their hearts what’s going on in the rest of the body, so the heart never gets told to pump faster. Their maximum heart rate is 130 bpm.   
  • Their brains can’t tell the leg muscles to fire, which – in able-bodies folks – helps get blood back to the heart quickly. 
  • Their brains can’t tell the smooth muscle around arteries to expand and contract, so blood pressure stays low and oxygen delivery suffers.


While the brain can’t tell these systems what to do, the body can.  The same automatic stress response that causes your heart to race against your will when meeting your partner’s parents, getting up on stage to give a speech, asking for a raise, etc.  can still be triggered in paraplegics.

Little things, like needing to pee, trigger this response.  But so do big things.  Apparently some parapelegic athletes will do things like breaking their big toe right before a race!  Ahhh!!

No surprise that this is really dangerous, because long-term high blood pressure can supposedly trigger stroke and death.  Now officials are having to take starting block blood pressure.  If wheelchair athletes are too high, they can’t start the race.

Smells Like Steve Bannon

I can’t believe one of the biggest science experiments in the world, in a city I’ve been visiting for the past 11 years… may have been ruined by Steve Bannon?!

Okay, okay.  I don’t know enough to point fingers.  And he can’t be the only one with blood on his hands.  But my jaw literally dropped when the podcast I was listening to mentioned his name for the first time.  And that’s saying something, because I was laying on the floor on a foam roller, so there really wasn’t anywhere for my jaw to go.

Pro tip: you can fix some of your awful computer/phone/driving/sitting posture with a foam roller

Who knew physical therapy could be a fantastic excuse to listen to a zillion podcasts or watch a ton of TED talks?  Maybe start with this one and find out about the implosion of the Biosphere, a la Steve Bannon & co.
