I appreciate the responses. I guess I misunderstood the certification process. I thought there were 2 calculations. First after passing the hydration steps was that your "actual" weight had to be at or below the weight classification.
The second calculation would be the Minimum safe weight, based on the weight % body fat calculation.
So, by my understanding if Cutch weight 174.0 or 168 he would certify at the 174 weight class. And then a totally separate calculation to determine the minimum safe weight would be based on body fat calculation based on the weight at the time of certification?
Getting warmer. There's only 1 calculation, The "first" calculation posited above does not exist. The only calculation is to determine your BW @ 5% fat.
You can weigh anything on certification day. Do not have to be at or even near the weight classification where you're certified.
Maybe this will help. It's the 2 examples given in the rulebook. Much more to it, but I believe this will help...
No. 1. Student-athlete A has a urine specific gravity of 1.025 on September 6. The student-athlete is
instructed to return in 24 hours to be retested. Twenty-four hours later, the urine specific
gravity is 1.011. The student-athlete is allowed to weigh-in and weighs 168 pounds. The
skin-folds are measured and when calculated, give a body fat percentage of 12 percent. The fat
weight of 20 pounds is calculated by multiplying 168 pounds by 12 percent. The fat-free weight
of 148 pounds is calculated by subtracting 20 pounds from 168 pounds. The fat-free weight of
148 pounds and divided by 0.95 equals 156 pounds. This is the lowest allowable weight-ONE
[LAW1] calculated with five percent body fat.
The minimum wrestling weight must take into account both LAW1 and LAW2. Therefore, the
higher of LAW1 and LAW2 will be the minimum wrestling weight [MWW] for the season.
MWW=156.
1. Specific Gravity = 1.025
Specific Gravity = 1.011 (24-hours later.)
2. BW = 168 lb.
3. BF = 12%
4. FW = 168 lb. x 0.12 = 20 lb.
5. FFW = 168 lb. – 20 lb. = 148
6. LAW1 = 148 lb. / 0.95 = 156 lb.
7. # of weeks = 15 weeks.
8. LAW2= 168– (1.5% x 15 wks x 168) = 130.2 lb.
9. LAW1= 156 lb.>LAW2=130.2 lb.
Therefore, LAW1=MWW=156 lb.
No. 2. Our next example is student-athlete B. On October 25, the urine specific gravity is
1.016, hydrated body weight is 225 pounds and the percentage of body fat is 18 percent. This
gives the wrestler a fat weight of 40.5 pounds (225 X 0.18) and a fat-free weight of 184.5 pounds (225 - 40.5). The LAW1 with five percent body fat is 194 pounds (184.5/0.95). The LAW2 is 198 pounds calculated by losing a maximum of 1.5 percent of original body weight per week
[225 – (0.15 X 8) (225)]. Since the LAW2 is greater than the LAW1, the LAW2 of 198 pounds
becomes the MWW. Although close, the wrestler could not compete in the 197-pound weight
class but must compete at HWT (285).
If desired, the student-athlete could retest using the gold standards of refractometer and underwater weighing with a direct measure of residual volume. The bod pod is another viable option for retesting. The MWW achieved with these measurements would form the basis for the certified weight class.
1. Specific Gravity = 1.016
2. BW = 225 lb.
3. BF = 18%
4. FW = 225 lb. x 0.18 = 40.5 lb.
5. FFW = 225 lb. – 40.5 lb. = 184.5 lb.
6. LAW1 = 184.5 lb. / 0.95 = 194 lb.
7. # OF WEEKS = 8 WEEKS
8. LAW2 = 225-(1.5% X 8)(225)=198 lb.
9. LAW2> LAW1; therefore, LAW2 becomes MWW of 198 lb.
Weight Class = 285 HWT
