The athlete had an injury of the knee (patellar tendinitis/jumper's knee) for years. When you see his running before it's obvious why. Lots of pushing, leading to excessive vertical oscillation (bouncing) which increase the impact of landing and the eccentric load of the quadriceps extensor-mechanism. At the end of the session, there's less push off (still too much) also the time spend on support is reduced (cadence up) which will increase the benefits of muscle-tendon elasticity to regain height again. Still lots of issues to work on.
I'll try to clarify. Overstriding happens because of poor frontside mechanics and insuficient vertical displacement. With sufficient vertical displacement the foot completes its cycle and lands where it's supposed to. In pose method, frontside mechanics and vertical displacement are also decreased, but to force the foot to land properly, pose runners deliberately shorten their stride. In other words they are understriders. This is not a bad way of running, but it is not efficient either.

Hi there, No good poserunners do not deliberitely shorten their stride. The landing happens passively and the movement of the swingleg after take-off is related with the angel of lean. The angle of lean detemines cadence, stridelenght and ROM of legs.

The first part of the video actually shows solid running form while the last part of the video shows poor running form. In the beginning he has good stride length and vertical displacement. In the end he is making small, inefficient steps, has little vertical displacement and too much backside mechanics. As for his injury, it is not related to running form, and will continue to trouble him even after the change in running style.

Sorry, don't agree and you'll find very few (if none) experts on running agreeing with you. Vertical displacement and big stride lenght are not persé signs of efficient running. Good running technique is about landing with the least amount of braking, (thus landing under the body), less vertical oscillation (no active push-off, instead use of muscle-tendon elasticity), a short time of support spend on the ground and using gravity as a motive force.
I do respect your opinion however.

at 1:18 what is the elastic band looking thing connected to his feet? Could you tell me where i can buy them? thanks.

It's the EZ-running belt, which is developed by posecoach Joe Sparks. If you google these words, you find his website. It should be used with caution, meaning only in short runs (30-50m). It'll help you improve a perception of running without striding out in front and push-off action . It'll also develop the correct awareness (timing and direction) of pulling the ankle under the hip. BUT only if you know and understand some about poserunning.
