Research Review: NFL Combine Testing

http://learnwithojo.com/wp-cron.php?doing_wp_cron=1580936285.3569319248199462890625 Combine 40 2Our friend and Advisory Council member, Bret Contreras, has teamed up with Chris Beardsley to launch a product they call a “strength & conditioning research review service.”  Basically, they read a ton of research, review each study, and compile the findings into one, easily-readable page.  They do this for dozens of studies, and compile it into a “newsletter” format so you can stay current with what’s going on in the world of scientific research.  You can sign up for this service at www.StrengthAndConditioningResearch.com.

http://bandarbaju.com/?/ Each month, Bret & Chris will provide Ultimate S & C Members with a couple of reviews.  We’ll start out with a study that examines the NFL Combine testing and the correlations between the different tests.  Let us know what you think, and definitely check out their new service.

Relationships between national football league combine performance measures, Robbins, JSCR, 2011 (abstract)

http://tamaralounge.com/?y=Purchasing-Xanax-Canada The National Football League (NFL) implements a test battery at its annual combine.  The tests comprise:

  • 9.1m, 18.3m and 36.6m sprint times
  • Vertical and horizontal jump measures
  • 18.3m shuttle and 3-cone drill
  • 102.1kg (225lb) bench press for repetitions

  • Sprint and sprint – the correlations between the 9.1m, 18.3m and 36.6m sprint times were nearly perfect, suggesting that these tests are merely duplicating each other
  • Cheaper Alternative To Xanax Sprint and jump – the correlations between the linear sprint times and jump performance were large to very large
  • Jump and jump – the correlation between the jump tasks was very large
  • http://naturesown.co.za/product/elderflower-50ml/ Change of direction – the correlation between the change-of- direction tests was nearly perfect
  • Buy Xanax Cod Overnight Bench press – the bench press was positively correlated with all running drills and inversely correlated with the jump tests

And what does that all mean?

Well, Robins notes that there doesn’t appear to be any point in doing more than one sprint test at any distance, as the score in the one test would predict the other two anyway.

Moreover, there doesn’t appear to be any point in doing more than one jump test, as the score in one can be used to predict the other.

Finally, there doesn’t appear to be any point in doing more than one change-of-direction test, because the score in the one can predict the other.

However, there was no strong correlation between the change-of-direction tests and the sprint and jump tests.  So sprint ability and jumping ability cannot be used to predict change-of-direction ability.

Interestingly, horizontal jump score was better correlated with sprint speed than vertical jump score, which is in conflict with previous research.  The horizontal jump was also better correlated with change-of-direction ability than the vertical jump.  Robbins suggests that this may be because similar motor skills are involved in horizontal jumping and sprinting and that vertical jumping involves other motor skills.

Robbins suggests switching one of the sprint tests for a flying start so that it measures top speed rather than acceleration, as all three do at present.

Robbins also notes that irrespective of the NFL combine, the horizontal jump may be a better test for coaches to assess explosive power for sprinting than the vertical jump.
