The Effects of Speed on Running Economy
If you're running at slower speeds like the speeds we tested at probably on average you're still going to get a benefit from these this well. The relationship there is going to be closer to a one to one ratio if you're running a slow speed. One 1.5 percent that you might get at 12 kilometers an hour might actually mean mean the same as I don't know 2 2.5 percent at 16 kilometers an hour yeah.
We have two interviews in today's episode. First, Dr. Dustin Joubert discusses new research on the effect carbon fibre plated "super shoes" have at slower speeds and how it differs from at faster speeds. Then Dr. Amol Saxena shares a case series of how rapidly transitioning to running in super shoes may increase the risk of navicular bone stress injuries.
IN THIS EPISODE YOU'LL LEARN ABOUT:
-The running economy benefits of super shoes at 10 and 12 km/h, and how it compares to the previously studies speeds in the 14-16 km/h range
-More non-responders to super shoes at slower speeds?
-How the observed running economy improvements translate to performance gains at marathon times in the 3:30 to 4:15 range
-Navicular bone stress injuries: causes, symptoms, diagnosis and treatment
-A case series of how rapid transition to training and racing in super shoes may be linked with navicular bone stress injuries
-Advice for safely transitioning into running with super shoes
