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.

• Keep a hard copy (worksheets) for your records and as a means of backup. Worksheets are available at mhsaa.com.

Page 7: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

1) Go to www.nwcaonline.com

2) This is what the home page looks like…select OPTIMAL PERFORMANCE CALCULATOR from the WEIGHT MANAGEMENT tab.

Page 8: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

Next, select LOGIN from the menu options at the top of the page.

Page 9: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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.

Page 10: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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.

Page 11: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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.

Page 12: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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.

Page 13: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

IMPORTANT NOTE: At the initial LOGIN enter your school ID and password which will bring you to this page.

Page 14: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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!

Page 15: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823
Page 16: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823
Page 17: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

This is an example of a completed form by which data was entered using the TAB key to move from field to field.

Page 18: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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.

Page 19: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

When doing an APPEAL for a wrestler, click on the APPEAL link under the assessor pull down menu.

Page 20: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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!

Page 21: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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!

Page 22: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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!!!

Page 23: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

To view or print the school’s Alpha Master Report, simply click on that link under the assessor menu pull down bar.

Page 24: Program For Wrestling Weight Monitoring Assessors Michigan High School Athletic Association 1661 Ramblewood Drive East Lansing, MI 48823

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!

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%
