CSCS Practice Questions – Exercise Technique Part 2

Posted by on May 29, 2013 in Exercise Technique, Practice Questions, Review Topics | 0 comments

For this question and questions like it, I’m going to use a simple rule I learned from Kelly Starrett of San Francisco Crossfit.  Kelly is creator of mobilitywod.com, and author of Becoming a Supple Leopard: The Ultimate Guide to Resolving Pain, Preventing Injury, and Optimizing Athletic Performance (affiliate link).  He’s been a huge influence on improving my mobility and making movements pain free.  If you haven’t checked out his work, I highly recommend it.

I’m not sure if the rule has an official name, but it’s simple “That which is loaded first, gets loaded most.”  Kelly uses this rule a lot in explaining squatting mechanics, and how the hips should be loaded first as to take the load off the knees.  Try it, the rule works.  I know because my knee will pop when I load sequence improperly, but if I load hips first it doesn’t pop.

So let’s assume this rule is true for the purposes of the previous question, in that case the correct answer seems fairly obviously to be

A. Eccentric Plantar Flexion

Alternatively you could reference Chapter 17 and memorize the components of high velocity sprinting.  Also, it was obviously necessary to know that plantar flexion is the action of pointing your toes away from yourself.  As you sprint, you absorb energy with eccentric plantar flexion as you actively resist having your toes point towards you but with a force less than the force of you contacting the ground, thus lengthening the muscles involved in plantar flexion and by definition an eccentric muscle action.

Next Question
What are two good coaching cues to give an athlete who is about to perform the T-test?

I. “Focus your eyes on each cone”
II. “Keep your head in a neutral position”
III. “Keep your head slightly tilted towards each cone”
IV. “Focus your eyes straight ahead”
A. I and II only
B. II and III only
C. II and IV only
D. III and IV only

Hint: this is still material from the chapter 17, but you have to know what the T test is too..
