Test and evaluation
Reminder
• Wrestlers will be allowed to compete at their
approved lowest minimum weight during an
appeal for a lower weight.
• Wrestlers will be allowed to begin losing 1.5%
immediately following the Alpha Weigh-In. It
does not matter if they plan to appeal or not.
• Established Jan. 15 as the last date for
hydrostatic appeals.
• Established a 48-hour wait period for all
wrestlers that fail the specific gravity test for both
skin fold & hydrostatic assessments and
appeals.
NWCA ONLINE PROGRAM
• Upon successful completion of this course, the
MHSAA will send each assessor their user ID
and password, along with a list of wrestling
schools and passwords.
• Only the registered assessor shall input data
and use their ID and password- DO NOT
SHARE YOUR PASSWORD WITH ANYONE!
• Keep a hard copy (worksheets) for your records
and as a means of backup. Worksheets are
available at mhsaa.com.
1)
2)
Go to www.nwcaonline.com
This is what the home page looks like…select
OPTIMAL PERFORMANCE CALCULATOR from
the WEIGHT MANAGEMENT tab.
Next, select LOGIN from the menu options at
the top of the page.
This is the area where you LOGIN to the system. First enter your assessor ID
and password, which is information that was supplied to you by the MHSAA
after successful completion of the in-service course & exam.
You now have many options in the menu bar at
the top of the page.
As an assessor, you click on ASSESSORS at the
top of the page, found between the instructions
and educational links.
Once you click on ASSESSORS, you will have 7
different options. When first assessing a team, you will
click HIGH SCHOOL INITIAL ASSESSMENT to enter
the data into the Web site for the first time.
Select your school from the drop-down list and enter the SCHOOL PASSWORD
from the Master List that was mailed to you by the MHSAA with your assessor
ID and password.
IMPORTANT NOTE: At the initial LOGIN enter your school ID and password which will
bring you to this page.
INITIAL ASSESSMENT
• The following page is form on which all data is entered.
• Enter the Name, Grade and Gender of the wrestler at the
top of the page.
• Enter the Alpha Weight and indicate whether or not the
wrestler passed the specific gravity test. If they failed
the hydration test, stop right there and do not enter any
further data- the wrestler cannot be reassessed for 48
hours!
• Then enter all measurements, as you go, by using the
TAB key to move from field to field. By using the TAB
key, the program makes the calculations automatically!
This is an example of a completed form by which data was entered using the TAB
key to move from field to field.
Once Completed…
• Once you have completed entering a data
for a wrestler, click SAVE CERT at the
bottom of the page, and then move on to
the next wrestler.
When doing an APPEAL for a wrestler, click on the
APPEAL link under the assessor pull down menu.
By clicking APPEAL, you will be brought to this screen of wrestlers who had
an initial assessment done. In entering an APPEAL, first click on the
SELECT link beside wrestler’s name who is appealing from the above
menu!
Next, enter the
data by using
the TAB key just
as you did for an
initial
assessment.
Once
completed, click
SAVE APPEAL
at the bottom of
the page!
CRITICAL NOTE:
When doing either an
initial assessment or
appeal, it is NOT
NECESSARY to
complete the
CERTIFICATION
PORTION of the form
where it asks for
signatures of the
athlete, athletic
administrator, ATC and
coach. By hitting
SAVE at the bottom of
the screen, you have
made the assessment
or appeal official.
There is no need to
sign or send any paper
to the MHSAA!!!
To view or print the school’s Alpha Master Report,
simply click on that link under the assessor menu pull
down bar.
This is a copy of the
Alpha Master Report
that each school’s
coach must print off and
exchange with opposing
coaches prior to the
start of each
competition.
Appealed data will
appear on the Alpha
Master report, along
with appeals that have
been denied because of
missed time frames or
unacceptable
measurements.
Note that this form does
NOT have to be signed
or does NOT have to be
mailed to the MHSAA!
To view or print an individual wrestler’s weight loss
plan, simply click on that link under the assessor menu
pull down bar.
Again, no
signatures are
necessary and
this form is
simply for the
informational
and education
purposes of the
school wrestler
and coach!
For help, assistance or questions, click either the FAQ
(Frequently Asked Questions) link, with a section
devoted to Assessor FAQ’s or…
Hit the HELP link, which will put you in contact directly
with the NWCA for technical assistance or questions.
Any questions about the NWCA site itself or any
issues with the entry of data, contact Pat Tocci at the
NWCA.
It is important to note then when an assessor
switches entering data of one school to
another school, YOU MUST LOG OFF and then
re-log on under your password and that new
school’s ID number and password. It is critical
that you log off when finished entering data, or
switching to another school or link within the
Web site!

Skinfold measurement verification
Data verification & entry
Hydration Requirement
• Athletes must be in a proper state of hydration to
determine their correct alpha weight
• Students should not exercise before the Alpha Weigh-In
• Specific gravity assessment of the urine will determine
whether the wrestler may participate in the skinfold
measurement process
Hydration Requirement (cont’d)
• This is simply a pass/fail assessment
• Specific gravity >1.025g/ml is a failed test
• “Alpha Weigh-In” must be conducted before the
athletes participate in that day’s practice or
conditioning

Specific Gravity Assessment
Procedure (cont’d)
• Instruct athletes to drink 6-10 glasses of
water daily for 2-3 days prior to this test
• Also, instruct them to urinate at least 1-2
times during the day prior to this test to
prevent urine from becoming too
concentrated
Specific Gravity Assessment
• School Volunteers control the
environment
• Provide collection cup for one
athlete at a time
• Athlete enters a secured area, one at
a time
• Athlete collects a midstream sample
& holds own specimen during test
Specific Gravity Assessment
• Test = Dip Multistix and remove
immediately holding horizontally
• Hold horizontal, wait 45 seconds and then
compare to color strip
• Continue with skinfold assessment if
SG <1.025 (passing)
• Athlete-empty cup in toilet, cup in waste

Calculations
•
•
LOHMAN Equation for Body Density
BD= [1.0973 (sumSFx.000815)]+[(sumSF)2x.00000084]
sumSF=TricepsSF+SubscapularSF+AbdominalSF
• (each skinfold value is an average of the three
recorded)
• carry out calculations to five places past the
decimal
• e.g. 1.08787
Skinfold Assessment
Calculations
• Brozek Equation for Body Fat from
Body Density
• % BF = (457 / BD) - (414.2)
carry out calculations to two places past
the decimal
 e.g. 12.34%

Skinfold Assessment
Calculations-Male
• Minimum Wrestling Weight @ 7%
• MWW = ([1-(%BF/100)] x TBW) / (.93)
• Alternate method
Fat Weight (FW) = TBW x (%BF/100)
 Lean Body Mass (LBM) = TBW - FW
 MWW = LBM / .93

Skinfold Assessment
Calculations-Female
• Boileau Equation for %Body Fat
– %BF=[1.35x(sumSF)] -[0.012x(sumSF)2] - 3.4
– sumSF= Triceps SF + Subscapular SF
– (each skinfold value is an average of the three
recorded)
•
MWW (females) = LBM / .88
Skinfold Assessment
Calculations
• Sample Calculation For Male
 Triceps= 4, Subscap= 5.2, Abdominal= 6.8
 sum SF = 16
• BD=[1.0973-(16 x.000815)]+[(16)2 x.00000084]
• BD=1.08446
• %BF=(457/BD)- 414.2 = 7.2%
