Sinclair Coefficient Formula
The following formula is used to calculate the Sinclair Coefficient.
SC = T / (10 ^ {(A - B * log10(W))})Variables:
- SC is the Sinclair Coefficient
- T is the total weight lifted by the athlete (kg)
- A is the coefficient based on the world record total in the heaviest class (kg)
- B is the coefficient based on the progression of world records from the lightest to the heaviest classes (kg)
- W is the body weight of the athlete (kg)
To calculate the Sinclair Coefficient, divide the total weight lifted by the athlete by 10 raised to the power of the difference between the coefficient based on the world record total in the heaviest class and the product of the coefficient based on the progression of world records from the lightest to the heaviest classes and the base 10 logarithm of the athlete’s body weight.
What is a Sinclair Coefficient?
A Sinclair Coefficient is a method used in Olympic weightlifting to compare different weight classes. It is a coefficient that adjusts the total weight lifted to account for the athlete’s body weight, allowing for a fair comparison between athletes of different sizes. The coefficient is updated every Olympic year based on the world records in each weight class.
How to Calculate Sinclair Coefficient?
The following steps outline how to calculate the Sinclair Coefficient.
- First, determine the total weight lifted by the athlete (T) in kilograms.
- Next, determine the coefficient based on the world record total in the heaviest class (A) in kilograms.
- Next, determine the coefficient based on the progression of world records from the lightest to the heaviest classes (B) in kilograms.
- Next, determine the body weight of the athlete (W) in kilograms.
- Finally, use the formula SC = T / (10 ^ (A – B * log10(W))) to calculate the Sinclair Coefficient.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Total weight lifted by the athlete (T) = 150 kg
Coefficient based on the world record total in the heaviest class (A) = 500 kg
Coefficient based on the progression of world records from the lightest to the heaviest classes (B) = 0.05 kg
Body weight of the athlete (W) = 80 kg
