Lab #6  Metabolic Syndrome - COG, COM, and Balance  10/15-10/19

Purpose/Goals  This lab is two-part.  the first purpose is to determine how many of the risk 
factors (hereditary and environmental) of Metabolic Syndrome you have.  You will also explore
various scenarios of COG/COM to evaluate how balance is best maintained.

Textbook  Chapters 6, 13  Readings from electronic reserve

Equipment  Blood pressure program, footballs, backpack with weights, balance board,
 belt with sock attached

Task  Complete Survey (you, sibblings, parents, grandparents), measure your blood pressure
find your BMI or skinfold estimate of adipose tissue percentage from previous lab.  You and 
your lab partner(s) will be involved in several experiments involving COG/COM and balance,
record findings.

Procedure/Data  
I.  Remove the survey, complete data, answer questions carefully, and hand in on Friday as a
part of your test.  If computer program is up and running (ask Missy) measure your blood 
pressure.  You will also need to find your BMI and/or skinfold estimate of fat from previous lab.

II.  A.  In the gym/outside you and your partner thow a football back and forth as a spiral (nose
to nose).  Describe rotational pattern and flight of ball.

_____________________________________________________________________________

   B.  Now throw a "lame duck" pass (end over end).  Describe rotational pattern and flight .

_____________________________________________________________________________

   C.  What does the difference between the two passes; flight pattern and rotation have to do 
        with COM?______________________________________________________________

______________________________________________________________________________

III.  One partner will stand with feet shoulder width apart, legs straight and the other partner will
see which requires more force; from anterior or from side to push off balance.

_______________________________________________________

   B.  Same as A, but knees are flexed.

________________________________________________________

   C. One partner stands with feet staggered, leg straight while other partner determines more 
   force;  from posterior of from side  to push off balance.

_______________________________________________________

   D.  Same as C, but with knees flexed.

_______________________________________________________

   E.  Same as B and D, but add the backpack with weights to the back.  How does that affect
   balance?___________________________________________________________________

   ___________________________________________________________________________

IV. A  One partner tie the belt with the sock attached on.  Step on the balance board and stand
with feet side by side only 2-3 inches apart, legs straight.  Partner will time how long you are
able to maintain balnace.  (Repeat 3 times and record best time)

	Time______________________

   B.  Same as A, except put the backpack with weight on.

	Time______________________

   C.  Same as A, except hold the backpack in the non-dominant hand below the waist.

	Time_____________________  Note also postural adjustments___________________

______________________________________________________________________________

   D.  Same as A, except feet are shoulder width apart and knees flexed.

   E.  Same as B, but with feet shoulder width and knees flexed

   F.  Same as C, but with feet shoulder width and knees flexed

Analysis and Interpretation 
 
	1.  How would you place the feet if you were receiving  force from the anterior?

	2.  How would you place the feet if you were receiving force from the side?

	3.  What did adding the backpack to the back do to the COG?

Application  
	1.  Why do lineman in football get down into a three point stance?

	2.  What did the belt with the sock attached represent?

Questions
	
	1.  Diabetes is a high risk factor for cardiovascular disease.  How does it actually
	    cause damage?

	2.  Describe the most balanced position you could be in if only your feet are allowed 
	    to contact the ground.
