Wilks coefficient

Wilks coefficient

or
Wilkes' formula
is a mathematical ratio that can be used to measure the relative strength of powerlifters despite the athletes' different weight classes. Robert Wilkes, CEO of Powerlifting Australia, is the originator of the formula.

The formula was updated in March 2022 to ensure the odds were rebalanced so that men's and women's results were better matched and the extreme weight classes were brought into better balance with the middle weight classes. [1]

Equation[edit]

The following equation is used to calculate the Wilks ratio. The total weight lifted (in kg) is multiplied by a factor to find the standard amount lifted, normalized across all body weights.

Coeff = 500 a + b x + c x 2 + d x 3 + e x 4 + f x 5 {\displaystyle {\text{Coeff}}={\frac {500}{a+bx+cx^{2 }+dx^{3}+ex^{4}+fx^{5}}}}

x is the athlete’s body weight in kilograms.

Validity [edit]

One journal article was written on the topic of testing Wilks' formula. [2] Based on the world record holders for men and women and the top two athletes in each event at the 1996 and 1997 IPF World Championships (a total of 30 men and 27 women in each event), it was concluded:

• There is no bias for men's or women's bench press and totals.
• Women's squats show a favorable bias toward middleweight athletes, but men's squats do not.
• There is a linear unfavorable trend towards heavier men and women deadlifting.

Example[edit]

The main function of the Wilks formula is in competitive powerlifting. It is used to determine the best athletes in different weight classes and can also be used to compare male and female athletes as there are formulas for both genders. The first, second and third places on the podium, within the limits of their age, weight and gender, are awarded to the participants who lifted the most weight, respectively. If two athletes in a class reach the same overall total weight, the lighter athlete is determined to be the winner.

The Wilks formula is used to compare and determine the absolute champions in different categories. The formula can also be used in team and handicap competitions where the team consists of athletes of different body weights. The Wilkes formula, like its predecessors (the O'Carroll [3] and Schwartz [4] formulas), was created to correct the imbalance where lighter athletes tend to have a higher power-to-weight ratio, and lighter athletes tend to lift greater weight compared to its own weight. This occurs for a number of reasons related to simple physics, the nature of the structure and limitations of the human skeletal and muscular system, and shorter leverage in smaller people. [5]Note in the results section that lighter athletes weighing less than 100 kg achieve amounts of ten times their body weight, while heavier athletes do not. The Wilkes System is primarily a handicapping process that provides an adjusted statistical method for comparing all athletes of different classes and groups on an equal basis and makes allowances for differences.

Under this scheme, a male lifter weighing 320 pounds and lifting a total of 1,400 pounds would have a normalized lift weight of 353.0, and a male lifter weighing 200 pounds and lifting a total of 1,000 pounds (the sum of their highest successful attempts at the lift). squat, bench press and deadlift) would have a normalized lift weight of 288.4. So a 320 pound athlete will win this competition. Notably, the lighter athlete was actually stronger based on their body weight, totaling 5 times their body weight, while the heavier athlete could only handle 4.375 times their body weight. Thus, the Wilks coefficient

places more emphasis on absolute strength rather than ranking athletes solely based on the athlete's relative strength compared to body weight. This creates a level playing field between lightweight and heavyweight athletes—lighter athletes typically have higher levels of relative strength compared to heavier athletes, who tend to have higher amounts of absolute strength.

Alternatives[edit]

While the Wilkes coefficient was used by the IPF until the end of 2018[6][7], other federations have used different coefficients or even created their own, like NASA. The IPF transition comes at a time when the Olympic Weightlifting Federation (IWF) [8] decided to switch from the existing Sinclair coefficient to Robie points in June 2022. Former IWF technical director Robert Nagy developed the Robie points system. Robie points are calculated based on actual world records in the category, and the value of a world record result is the same (1000 points) in all weight classes.

Alternatives are the Glossbrenner Coefficient [9] (WPC), Reschel Coefficient [10] (GPC, GPA, WUAP, IRP), Outstanding Lifter Coefficient (OL) or NASA Coefficient [11] (NASA), Schwartz/Malone Coefficient, and Siff Coefficient .

While all ratios take gender and weight differences into account, some also take age differences into account. For the cadet and junior age groups, the Foster coefficient is used, and for the main age group (40 years and older) the McCulloch or Reschel coefficient is used.

TABLE OF ABSOLUTE COEFFICIENTS - WILKS FORMULA

The Wilks formula is used in powerlifting competitions to compare the results of athletes of different weight categories and identify the absolute champion of the competition. The Wilks coefficient reflects the relationship between the athlete’s own mass and the weight he lifted both in one of the exercises and in the total eventing event.

The coefficient calculated using the Wilks formula is used to compare the results of athletes of different weights. The Wilks coefficient reflects the relationship between the athlete’s own weight (with an accuracy of 0.1 kg) and the weight he lifted.

To determine the absolute result, it is necessary to multiply the triathlon sum by the Wilks coefficient. The athlete with the highest absolute odds has preference. For example: An athlete weighing 45.5 kg gained 300 kg. We determine the absolute coefficient (marked in red) and multiply by the amount. Absolute result = 1.1382 *300 =341.46

TABLE OF ABSOLUTE COEFFICIENTS - SCHWARTZ/MALONE FORMULA

1. Go to the link 2. Check in the item “Totals are given in” kg 3. In the item “Use the following formulas” uncheck all the boxes except Schwartz/Malone 4. In the item “Formula used to age adjust Masters (age 40 and above ) results" set to Schwartz Masters Formula 5. In the item "Adjusting for Teen (14-23 years) totals" set to For all formulas 6. Below in the "WEIGHT" field enter the athlete's own weight in the format 96.6 (Required with a dot, not with a comma!) 7. In the “TOTAL” field we put one 8. In the “GENDER” field we select the gender: M - men, F - women 9. In the “AGE” field we enter how many full years the athlete is 10. Below we click on “Calculate” 11. In the third column from the right “SCORE” is the Schwartz/Malone coefficient, which is used in IPA competitions

TABLE OF ABSOLUTE COEFFICIENTS - REISCHEL FORMULA

Since primitive times, people have wondered what is stronger and how to determine the strength of people who have different body weights and show different results? When powerlifting competitions reached mass and popularity, there was an urgent need to determine the absolute winner. The Reichel formula is adopted in many powerlifting federations to determine the absolute winner coefficient, we are sure it will be useful for you too!
