CSCS Practice Questions – Exercise Science Part 6

When I encountered a question about Tanner’s classification, I didn’t even bother to answer the question because I knew I had to review it.  However, had I given it some more thought I probably could get close to having a 50/50 shot at answering it correctly come test time.

In the question I created, there are some hints buried in the context.  Let’s re-read the question:

You are coaching a middle school football team and one of your athlete’s physicals comes back with a Tanner classification of Stage 2.  What does this classification describe?

Some thoughts come to mind:
-Middle school, these kids are 12-14 years old
-Physicals, what do physicals typically involve (ugh, the dreaded turn your head and cough!)

Now let’s look back at the possible answer:

A.  Training status  —Seems unlikely…middle school students aren’t likely to be involved in heavy training to begin with.  Why would this be a part of a physical?  I don’t remember anything like this being a part of my physical at least.
B.  Emotional state  Maybe if the physical was done by a therapist
C.  Biological age
D.  Emotional age  Again with the therapist

So the answer to the question in the previous post is obviously C.  Clearly the possible answers I selected are probably too easy as too much can be gleaned from the context.  Trust that the NSCA will not create such easy questions!  But practice your reasoning so you have a fighting chance on questions you don’t know 100%.
Now let’s understand the why for this question.

What is Tanner’s Classification?
Tanner’s classification exists to give some idea how far along in development a young athlete might be.  I remember in junior high a fellow student had a full beard at the age of 13 and was running a 4:54 mile run.  He was obviously almost fully developed, and as a result had significantly superior muscle mass and strength.  The Tanner classification has 5 stages, with 1 being completely undeveloped (puberty not yet started) and 5 being a full adult male, or in the case of my junior high experience- a teenager with a full beard.

Next Question!

When you move a muscle, neurons in your brain fire to recruit motor units.  When a motor unit is activated by a neuron, every muscle fiber in that motor unit fully contracts because:
A.  the principle of total recruitment
B.  the all-or-none law
C.  Moore’s law
D.  muscle spasm

Hint: the above picture won’t help you!  Read chapter 1.
