摘要翻译：
目的：在力量举重运动中，运动员的体重对总的成绩有很大的影响。动力提升分为装备型和原始型。专业原始力量举重比赛使用威尔克斯评分系统来比较和排名力量举重的结果，以选择获胜者。Wilks公式是五阶多项式，适用于1987-1994年装备的动力提升结果。威尔克斯公式本应每2至5年更新一次，但从未修订过。这项研究的目的是更新威尔克斯评分系统，用于专业原始力量举重。方法：从OpenPowerLifting.org数据库中收集了男子60-175公斤，女子44公斤及以上，每个体重级别的10个最高原始力量举总量。使用多项式回归，分别对男性和女性的这些数据进行多项式拟合。男性和女性的得分是用这些拟合计算的，并对结果进行评估。结果：4阶多项式最能反映力量提升总成绩与体重的关系。在这些拟合曲线上，男性得分归一化为500分，女性得分归一化为455分，使男女体重等级的最高得分达到相同水平。在不同体重级别的男性和女性中，这些分数似乎是相似的。这种均匀的体重得分在这里被认为是职业比赛评分系统的唯一最重要的特征。关键词：Wilks评分，修正预测曲线，多项式回归，动力提升

英文摘要：
  Purpose: In powerlifting the total result is highly dependent on the athletes bodyweight. Powerlifting is divided to equipped and RAW types. Pro RAW powerlifting competitions use the Wilks scoring system to compare and rank powerlifting results across bodyweights, to choose the winners. The Wilks formulas are 5th order polynomials fitted to equipped powerlifting results from the years 1987 - 1994. The Wilks formulas were meant to be updated every 2 to 5 years, but have never been revised. This study aims to update the Wilks scoring system for use in pro RAW powerlifting.   Methods: The 10 highest RAW powerlifting totals per weight class for bodyweights 60 - 175 kg for men, and 44 kg and up for women, were collected from the openpowerlifting.org database. Polynomials were fitted to these data separately for men and women, using polynomial regression. The scores for men and women were calculated using these fits, and the results are assessed.   Results: 4th order polynomials were chosen for best describing the dependence of powerlifting total result on bodyweight. The mens scores were normalized to 500 points, and womens to 455 points, on those fitted curves, to bring the top scores to the same level across weight classes of each sex. These scores appeared similar across the different weight classes for both men and women. This even scoring across body weights is here considered the single most important characteristic of a scoring system for pro competitions.   Key words: Wilks score, revised prediction curve, polynomial regression, powerlifting
