“…Performance on the coordinated exertion of force test did not significantly correlate with that of the pegboard tests but had a moderately significant relationship to the pursuit-rotor test in both sexes. The present results are similar to those of Nagasawa, et a/. (2001).…”

“…Also, it was reported that women perform better on tasks that demand dexterity, accuracy, and rhythmic control of fingers (Hatta, Otomo, Yoshida, Takaira, & Ohtake, 1993;Ruff & Parker, 1993). O n the other hand, Nagasawa, Demura, Yamaji, Kobayashi, and Matsuzawa (2000) reported that no significant sex difference was found in coordinated exertion of force based on target pursuit for subjects ages 19 to 23 yr. Nagasawa, Demura, Yamaji, and Shimada (2001) reported that the coordinated exertion of force was not significantly related to tapping and foot balance with eyes open for both sexes. However, little research has examined correlations between the coordinated exertion of force test and the widely used pegboard, pursuit-rotor tests, and sex differences on these tests.…”

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.

“…Houx examined gender differences in subjects from 20 to 80 years of age in choice reaction speed, which evaluates nerve function, and reported that males were superior to females [25]. Nagasawa et al examined CFE of the dominant hand in middle-aged and elderly people, and saw that males were superior to females [26]. There was no gender difference found in the nerve function of the maximal ability, which involves no information feedback.…”

“…Tests which evaluate nerve function differ in their conclusions concerning gender differences [27]. Nagasawa et al found gender differences in CFE of middle-aged and elderly people, and inferred that dexterity and speed of hands and fingers closely reflects to experiences of the movements in daily life [26]. The unique experiences of individuals create the CFE gender differences.…”

This study examines gender differences and laterality in maximal handgrip strength and controlled force exertion (CFE) in young adults. The subjects were 75 healthy young males (mean age 19.6 ± 1.6 yrs.) and 50 healthy young females (mean age 20.9 ± 1.9 yrs.). Maximal handgrip strength was measured twice. The subjects performed the CFE test three times after one practice trial. They matched their handgrip strengths to the demand values, which constantly changed and ranged from 5 to 25% of maximal handgrip strength. The difference between the demand value and the grip exertion value was used as an estimate of CFE. Maximal handgrip strength was significantly larger in males than in females in both the dominant and non-dominant hands, and was significantly larger in the dominant hand in both males and females. Insignificant gender differences were found in CFE of both hands. CFE was significantly superior in the dominant hand in both genders. In conclusions, gender differences are present in maximal handgrip strength of the dominant and non-dominant hands in young adults, but not in CFE of both hands. Laterality exists in maximal handgrip strength and in CFE for both genders

The purpose of this study was to examine the effects of aerobic exercise before a task on the ability to coordinate exertion of force (ACEF). [Participants and Methods] Ten healthy males and 5 females performed two trials in a random order: 10-minutes cycling at 60%V• O2 max (AE), and sitting without exercise (CON). The ACEF effect was evaluated using a continuous visual isometric grip task, and seven different force trials were performed 8 times each, a total of 56 times. [Results] In the AE trial the number of successful grip tasks significantly increased after 1 and 24 hours compared to the pre-test value; however, there were no significant changes in the CON trial. [Conclusion] Aerobic exercise before a task may enhance the promotion and retention of ACEF.
