“Sticking the Landing” Picture the gymnast on the otherside of the vaulting horse. Stick the landing, no knee flex, no instability / “shimmy”
“a quick flash of concentric” means just that.
All this landing stuff is eccentric isolation work. If and when one starts to adapt to the workload, whats the next thing that likely will follow a landing? With out even realizing, they will nail the landing and then start to come up (concentric) Concentric being an involuntary response. While flat footed landings, there is some flexion at the knee otherwise the muscles dont get hit and the forces at landing are transmitted skeletally (is that a word?) up the chain to hip, lower back, …
People think of eccentric work like in the weight room (lowering the weight, “working the negative”) But that work while having its value in training, doesnt match the duration time of a sprinter’s ground contact or jumper’s plant contact to release. Landings more specifically target / work this area.
When adaptation has occured, those same people default to adding more weight or say dropping from higher heights (the More is Better school of coaching) I suggest that overlaod can be acheived, and more specific to event requirements, by performing an dynamic/explosive action out from a “stuck” landing.
Does that help? If so, then you are smarter than the 2 knuckleheads that run this site. They couldnt even get my post from yesterday on another thread !!!!
This subject has a tie in to GB. The first publisher of my paper on this topic was a sports site run by a university in Scotland, and when I first presented my paper to an audience, Calvin Morriss (former bio-mechanist for GB Field and Track now same for rugby’s national team) was a fellow speaker.
