This study assessed the relationships between coordinated exertion of force and performance on pegboard and pursuit-rotor tests. University students (30 men and 30 women; M = 20.4 yr., SD = 1.1) matched their submaximal grip strength to changing demand values displayed as either a bar chart or a waveform appearing on the display of a personal computer and performed pursuit-rotor and pegboard tests. Sex differences were not significant. Correlations with maximal grip strength were minimal. Performance on coordinated exertion of force test was moderately correlated (men: r = −.42, women: r = −.70) with performance on the pursuit-rotor test for both sexes, but not with scores on the pegboard test. Scores on the coordinated exertion of force test and these two tests using upper limbs and fingers have little relation to maximal grip strength, and the correlations among them are similar for both sexes.
