Relationship between maximal acceleration in a sprint and specific horizontal strength in professional soccer players.
This data have been collected with a GPS system of 1 hz for GPS speed and 100 hz for triaxial accelerometer acceleration.
As you know (at least in a more simplistic approach ...) in a sprint, the value of the strength applied should depend directly on the acceleration demonstrated, specially the horizontal acceleration applied by, in this case, the soccer players, as F=m*a, where "F" is force, "m" is mass and "a" is acceleration, so for a sprint (horizontal F = m* horizontal a).
Few studies has showed us the relationship between speed and horizontal relative force applied, and also this relationship with the possibility of hamstrings injuries. Here I show you the relationship I have founded between maximal acceleration in a sprint with the value of the horizontal acceleration applied by soccer players in their first steps.
Conclusion: nothing new but most of time forgot, the importance of highlight the use of different means and methods specifically oriented to the development of specific horizontal acceleration for soccer players, based on the use of EXPLOSIVE longer steps.
Enjoy,
