The primary objective was to assess the relationship of maximum strength to weightlifting ability using established scaling methods. The secondary objective was to compare men and women weightlifters on strength and weightlifting ability.
Two correlational observations were carried out using Pearson's r. In the first observation (N = 65) the relationship of dynamic maximum strength (one-repetition maximum (1RM) squat) was compared with weightlifting ability; in the second observation (N = 16), isometric maximum strength (midthigh pull) was studied. Scaling methods for equating maximum strength and weightlifting results were used (load x (Ht), load x kg, load x lbm(-1), allometric, and Sinclair formula) to assess the association between measures of maximum strength and weightlifting performance.
Using scaled values; correlations between maximum strength and weightlifting results were generally strong in both observations (e.g., using allometric scaling for the 1RM squat vs the 1RM snatch: r = 0.84, N = 65). Men were stronger than women (e.g., 1RM squat, N = 65: men = 188.1 +/- 48.6 kg; women = 126.7 +/- 28.3 kg); differences generally held when scaling was applied (e.g., 1RM squat scaled with the Sinclair formula: men = 224.7 +/- 36.5 kg; women = 144.2 +/- 25.4 kg).
When collectively considering scaling methods, maximum strength is strongly related to weightlifting performance independent of body mass and height differences. Furthermore, men are stronger than women even when body mass and height are obviated by scaling methods.
主要目标是使用既定的缩放方法评估最大力量与举重能力之间的关系。次要目标是比较男女举重运动员的力量和举重能力。
使用皮尔逊相关系数进行了两项相关性观察。在第一次观察（N = 65）中，比较了动态最大力量（一次重复最大值（1RM）深蹲）与举重能力之间的关系；在第二次观察（N = 16）中，研究了等长最大力量（大腿中部拉力）。使用了将最大力量和举重成绩等同起来的缩放方法（负荷x（身高）、负荷x千克、负荷x磅体重（-1）、异速生长法和辛克莱公式）来评估最大力量测量值与举重表现之间的关联。
使用缩放后的值，在两项观察中，最大力量与举重成绩之间的相关性通常都很强（例如，对1RM深蹲与1RM抓举使用异速生长缩放法：r = 0.84，N = 65）。男性比女性更强壮（例如，1RM深蹲，N = 65：男性 = 188.1 +/- 48.6千克；女性 = 126.7 +/- 28.3千克）；应用缩放时差异通常依然存在（例如，用辛克莱公式缩放的1RM深蹲：男性 = 224.7 +/- 36.5千克；女性 = 144.2 +/- 25.4千克）。
综合考虑缩放方法时，最大力量与举重表现密切相关，与体重和身高差异无关。此外，即使通过缩放方法消除了体重和身高因素，男性仍然比女性更强壮。
