This study compared the relationship between isokinetic lifting test (ILT) performance and a maximal operational lifting test (OLT) with that between an isoinertial progressive lifting test (PLT) and OLT. Fifty subjects performed the ILT, PLT and OLT after familiarization trials. OLT was defined as the weight of the heaviest crate that could be lifted to 1.34 m with a progressive, incremental test. ILT performance was the force generated during a single maximal simulated lift on an isokinetic dynamometer. PLT performance was the maximal weight lifted to 1.52 m with a progressive, incremental protocol on a weight stack. OLT was highly correlated with ILT (r = 0.96) and PLT (r = 0.97); the standard error was similar for both linear regression equations. The results demonstrate that a single maximal voluntary lift on an isokinetic dynamometer is as good a predictor of OLT as in the PLT presently used in military recruit centers.
本研究比较了等速举重测试（ILT）表现与最大操作举重测试（OLT）之间的关系，以及等惯性渐进举重测试（PLT）与OLT之间的关系。五十名受试者在进行熟悉性试验后进行了ILT、PLT和OLT。OLT被定义为通过渐进式递增测试能够举升至1.34米的最重板条箱的重量。ILT表现是在等速测力计上单次最大模拟举重过程中产生的力量。PLT表现是通过在配重架上采用渐进式递增方案举升至1.52米的最大重量。OLT与ILT（r = 0.96）和PLT（r = 0.97）高度相关；两个线性回归方程的标准误差相似。结果表明，在等速测力计上进行的单次最大自主举重与军事新兵训练中心目前使用的PLT一样，是OLT的良好预测指标。
