Can you run faster with these?

By | Uncategorized | No Comments

I’ve never been a very fast runner. My Parkrun speed is only 6.2 mph. Mostly I run for the mood ‘high’ that running gives me. I reckon that Jill, the family guinea pig, can run faster than me (size related). Guinea pigs can run at speeds of up to 8 mph! How come they can go so fast? Looking at some of the tech in running shoes might help us to understand why. There was a great article in the British Journal of Sports Medicine about this. Lets look at the Nike ‘Vaporfly’, which is claimed to help us run up to 6% faster! This is due to three design changes:

Firstly a carbon-fibre plate that shifts the point of lift-off forwards, increasing the upwards and forwards forces of lift-off, much like the long foot of a guinea-pig!

Secondly: more springy foam in the sole, returning 32% more energy, a bit like the elastic tendons in a guinea-pigs leg.

Thirdly: a thicker sole, increasing stride length and improving efficiency.

If my legs were longer, maybe I would be able to run faster? If Jills were too, perhaps she also could. Now that would be scary! My own running shoes are made by Saucony. They are currently extremely muddy, having just come back from a run to Culham, and back, via a very muddy riverbank!

When cycling is better than walking…

We all agree, walking is good for you. Unfortunately, patients with spinal stenosis find that they get leg pain when they walk, because they get nerve compression at the bottom of the spine. Bending forward, however, relieves the pain. This means that getting around on a bike is much easier for these patients than walking. Find out more in this short video! There was a good summary of spinal stenosis in the BMJ.

Have you seen my shoes, Dad?

I don’t know about you, but my kids could never find things…. ‘Where are my shoes, Dad’? They would yell, as they stormed around slamming doors. ‘Wherever you left them’ was my standard answer, of course! (They were always under the sofa, btw….)

When I was doing my diagnostic ultrasound training, I would sometimes struggle to find one of the kidneys with the ultrasound scanner, but sometimes a kidney really isn’t there, because the patient only has one kidney. One of the problems with this is that the single kidney that is present is often a bit quirky: large, situated somewhere weird, and imperfectly constructed. This single kidney may be more prone to infection, and an infection of the kidney will often create low back pain, which is sometimes what brought the patient in to see us in the first place!

Patients with only one kidney are more prone to developing high blood pressure, so this will need to be monitored. Your kidneys are very important, so sometimes patients with one kidney are told to avoid contact sports, in case they damage their one kidney.

Statistically, Abingdon will have about 31 people who only have one kidney!
