The main objective of this study was to test the differences among four techniques for the determination of lifting abilities. This study introduced a new submaximal isometric strength testing technique. The proposed test was based on the concept of acceptable maximum effort (AME) which is the level of static exertion the individual is willing to perform voluntarily and comfortably without over-exertion (as opposed to the maximum ability of performance). Twelve male and five female subjects underwent the protocol of the four strength testing techniques investigated: isometric maximum voluntary contraction (MVC); maximum acceptable weight (MAW); maximum dynamic lifting (MDL); and acceptable maximum effort (AME). The results showed that MAW recorded the lowest values followed by AME, then MDL, then MVC. The correlation between AME and MAW was higher than that found between MVC and MAW. Also, it was found that AME is a reproducible measure of muscular functional abilities. On the average, the coefficient of variation was less than 15% for data for both males and females. The implications of these results in determining lifting abilities are discussed.
本研究的主要目的是测试四种测定举重能力的技术之间的差异。本研究引入了一种新的次最大等长力量测试技术。所提出的测试基于可接受最大努力（AME）的概念，即个体愿意自愿且舒适地进行静态用力而不过度劳累的水平（与最大表现能力相反）。12名男性和5名女性受试者接受了所研究的四种力量测试技术的方案：等长最大自主收缩（MVC）；最大可接受重量（MAW）；最大动态举重（MDL）；以及可接受最大努力（AME）。结果显示，MAW记录的值最低，其次是AME，然后是MDL，最后是MVC。AME与MAW之间的相关性高于MVC与MAW之间的相关性。此外，还发现AME是肌肉功能能力的一种可重复测量指标。平均而言，男性和女性数据的变异系数均小于15%。讨论了这些结果在确定举重能力方面的意义。
