Does anyone out there intentionally coach sprinters, on occasion, to slow after a run by deliberately trying to “stop”, as opposed to slowing by just slowing the running action down? And is this enough of a load, or too much of a load if from too great a velocity, to have an effect?
Yo! I tried this one myself back in 2005. I got one hell of a muscle pump that goes with increased fast twitch fibre recruitment in eccentric loading. Alas, I had to give up this method after this and many other rapidly stopping exercises resulted in Achilles tendon problems that still plague me. Incidentally, one of those exercises was the single leg jump which improved by 16cm as a direct result of well timed toe dorsiflexion in the non-jumping leg.(dorsiflexion >> plantarflexion)
With regard to magnitude of eccentric load, Mero 1994 measured maximal bounding to produce slightly higher braking forces than maximal running but maximal hopping and maximal stepping provided frighteningly higher (1.6-1.9x)braking forces altogether although at the expense of increased ground contact time.
