Here’s another research study I found that examined the ground reaction force (GRF) of team sport athletes and compared that to how fast they were during sprinting.
While you’re not a sprinter, it’s important to keep in mind that when taking a shot, you’re essentially looking to do the same thing as a sprinter- produce maximal horizontal force so that you can move as explosively as possible.
Anyway, here’s the info on the study.
Acceleration when shooting a leg attack is dictated by a variety of factors. These include body mass, ground reaction force, and gravity.
The force that you produce off the ground, or GRF, is really the only factor that you can influence with a properly designed training program.
While there are both horizontal and vertical forces that factor in to taking a shot, based on the sprinting studies I’ve looked at, the horizontal component is the most predictive of speed.
Additionally, various studies on sprinters have found that the horizontal force during starts from blocks is significantly correlated with acceleration.
Therefore, I think it’s safe to assume that focusing on horizontal force production should be the primary focus of a wrestling training program.
Goal Of Study- Based on the research available, the authors elected to look at GRF in team sport athletes who sprinted from a standing, athletic position.
Participants- 30 athletes (soccer, basketball, field hockey, rugby, and Australian Rules football) with 5 years of playing experience.
Testing- Subjects performed 6 maximal effort sprints covering 10 meters. All sprints were from a standing start with feet parallel. The subjects had a .3 meter window to gain speed before the 10 meter electronically timed test began.
Ground reaction force was measured just after the start and at 8 meters.
10 meter sprint time was significantly correlated with horizontal GRF. Based on this finding, they stated that the faster subjects applied more horizontal force which helped them achieve greater acceleration.
What Does This Mean To Wrestlers:
This study has the same conclusion as the last one I wrote about (Ground Reaction Force and Acceleration). What makes this conclusion more exciting though, is that the study utilized subjects who weren’t trained sprinters.
Again, just like in the last post, as a wrestler, this means that the more capable you are at producing horizontal force, the more likely you are to have a faster shot and produce more power when shooting.
