Is the only way to get faster is to stabilize the trunk? And if so, why is this so? The fuselage stability is the basis for a clean and effective running technique. A stable body is an anchor at which the shoulder girdle and pelvic girdle (and thus also arms and legs) get their hold in order to be able to work effectively.
Faster with Trunk stabilization?
That’s one of the reasons the sprinters are so muscular. The explosive acceleration of these sprinters results in extreme centrifugal, tractive and compressive forces. All these forces are absorbed and compensated by the fuselage. Because the quieter the fuselage during a sprint, the less “unbalance” the sprinter has and the faster he can run. This is exactly the goal of fuselage stabilization.
At greater distances, a stable trunk protects (among other things) against an unfavorable running style and thus reduces the orthopedic risk. Furthermore, a good trunk stabilization helps with an economical running style – this allows a higher average speed and in the best case even preserves the cardiovascular system.
But trunk stabilization alone is useless if a structured training with the right methodology and didactics is not carried out, in which all other components for a sprint training are taken into account.
