Is symmetry important for biomechanics and energy utilization?

Velocity, timing, stance and swing phases, injuries, center of pressure, step width, .... lots of good topics today

This time around we introduce some new literature to provoke some clinical thinking that will inform, amuse and hopefully entertain you.  We also introduce the newest athletic tape to the market, surely someone will rip off our idea, but hopefully they will tag our name to it and help make us famous.

Biology suggests that decades of running should invariably blow out your knees. Scientists are trying to understand why that doesn’t happen. -suggests that 98% of knees should fail after three decades of running. But they don't, and the big question is why not.
