Calculate Sinclair Total using lbs/pounds


    What is Sinclair Calculator and Points/Total

    The Sinclair Calculator is a tool used in the sport of weightlifting to compare the performances of athletes of different body weights and determine a hypothetical "Sinclair Total." This Total is an adjusted measure of an athlete's performance, considering their body weight and the coefficient, and it provides a way to assess how an athlete's performance would theoretically compare to others if they were all in the same weight class. This allows for a fair comparison of athletes and helps identify the most outstanding lifters regardless of their body weight, fostering a fair and competitive environment in the sport.
    Here's a breakdown of the key points and components of the Sinclair Calculator:

    Athlete's Performance:

    The starting point for the Sinclair Calculator is an athlete's actual total in a weightlifting competition. This total is the sum of the athlete's best lifts in the snatch and the clean and jerk.

    Body Weight

    The athlete's body weight, usually measured in kilograms, is another essential input. This value accounts for the athlete's weight at the time of the competition.

    Sinclair Coefficient

    The Sinclair Coefficient is a numerical value that adjusts an athlete's performance based on their body weight. It's derived statistically and is specific to each Olympic year. These coefficients are updated to reflect the competitive standards of the sport. The Sinclair Coefficients are usually calculated based on the Total World Records in various body weight categories, providing a benchmark for performance.


    To calculate the Sinclair Total, you multiply the athlete's actual total by the Sinclair Coefficient corresponding to their body weight category for that Olympic year.
    Sinclair Total = Athlete's Actual Total x Sinclair Coefficient
    This calculation is performed to estimate what the athlete's total would be if they were at the highest weight class while maintaining the same level of ability.


    The Sinclair Total is a normalized measure that allows for a fair comparison of weightlifters across different weight categories. It's especially valuable when determining the best overall weightlifter in a competition where athletes may vary significantly in body weight.

    Introduction to Weightlifting (Clean and Jerk) in Olympic Sports

    The sport of weightlifting, an integral part of the Olympic Games since their inception in ancient Greece, has evolved into a display of extraordinary strength, precision, and athleticism. Among the two primary lifts in competitive weightlifting – the Snatch and the Clean and Jerk – the Clean and Jerk stands out as a pinnacle of power and technique. It is a discipline that demands not only raw physical strength but also a high level of skill and mental focus. In this introduction to the Clean and Jerk in Olympic sports, we will explore the rich history, the fundamental techniques, and the incredible athletes who have made this discipline a cornerstone of Olympic competition. Whether you are a curious observer or an aspiring weightlifter, this exploration will shed light on the captivating world of weightlifting and its enduring place in the realm of elite athletic endeavors.

    What is Sinclair Coefficient?

    The Sinclair coefficient, often referred to as the Sinclair formula or Sinclair coefficient, is a method used in the sport of weightlifting to adjust and normalize the performance of athletes across different weight categories. It was developed to account for the fact that in weightlifting, athletes in different weight classes might lift different absolute weights, but this does not necessarily reflect their relative strength or skill. The Sinclair coefficient aims to provide a fair comparison of lifters' performances, irrespective of their body weight.

    The coefficient is updated and recalculated periodically, typically from the 1st of January the year after each Olympic year until the 31st of December of the next Olympic year. This ensures that the coefficients remain relevant and reflective of current weightlifting standards.

    The Sinclair coefficient for an individual lifter is determined using a mathematical formula. It starts with the lifter's bodyweight (denoted as 'x') and the weight of the world record holder for the total lift (i.e., the combined weight of the snatch and clean and jerk) in the heaviest weight category (denoted as 'B'). The formula then applies two main components:

    1. Normalization through Logarithmic Scaling: The first component involves taking the logarithm base 10 of the lifter's bodyweight and squaring it. This helps to account for the non-linear relationship between body weight and strength. In simpler terms, it acknowledges that a larger athlete doesn't need to lift proportionally more weight to be considered stronger.
    2. Calculation of Coefficient 'A': The second component calculates a coefficient denoted as 'A.' This coefficient is a result of the previous step and is then multiplied by 10 to adjust the scale. It essentially represents a scaling factor to ensure that the Sinclair coefficient falls within a specific range.

    If the lifter's bodyweight exceeds the weight of the world record holder in the heaviest weight category (B), their Sinclair coefficient is set to 1. This provision accounts for the idea that once an athlete surpasses the achievements of the heaviest weight category, their performance should no longer be adjusted, as they are already competing at the highest level.

    In essence, the Sinclair coefficient allows for a more equitable comparison of weightlifters' performances, enabling athletes from different weight categories to be ranked and evaluated fairly based on their relative strength, skill, and abilities, rather than just the absolute weight they lift. This makes it a valuable tool in the world of weightlifting, aiding in competitions, rankings, and the recognition of talent and potential across diverse weight classes.

    Clean and Jerk

    The clean and jerk is a two-part lift:


    The snatch is a single-movement lift:

    The "total" in weightlifting refers to the combined maximum weight a lifter can successfully lift in both the clean and jerk and the snatch during a competition. It's a measure of their overall strength and technique in these two lifts. Weightlifters aim to maximize their total to compete successfully in their weight class.


    The Sinclair score, a valuable tool in the sport of weightlifting, finds wide-ranging applications in the competitive arena. It serves as a means to level the playing field by allowing weightlifters from different weight categories to be fairly compared. This normalization of performances enables coaches, athletes, and competition organizers to assess and rank athletes based on their true strength and skill rather than simply the weight they lift. Sinclair scores are instrumental in competitions, helping to determine winners, award medals, and acknowledge outstanding performances. Furthermore, they aid in talent identification and development, allowing coaches to recognize potential across diverse weight classes and nurture promising athletes. Overall, the Sinclair score plays a pivotal role in promoting fairness and accuracy within the sport of weightlifting.
