Methods: Maximal grip strength was measured twice. Eight parameters derived from the force-time curve were selected to evaluate the developmental phase of muscle contraction. The subjects matched their submaximal grip strength to changing demand values, appearing with a sinusoidal waveform on the display of a personal computer. The subjects performed the controlled force exertion test three times with 1-min intervals (each trial lasted 40 s), after one practice trial. The total of the differences between the demand value and the grip exertion value for 25 s was used as an evaluation parameter. Results: Explosive grip parameters, except for time to fixed level and velocity of force development, showed significantly higher values in the dominant hand. The controlled force exertion parameter showed significantly lower values in the dominant hand. The integrated area for 1 sec, integrated area for 5 sec, and average force significantly correlated with the controlled force exertion parameter in the dominant hand. None of the explosive grip parameters correlated with the controlled force exertion parameter in the non-dominant hand. Conclusion: The controlled force exertion parameter relates to the integrated area parameters for explosive grip in the dominant hand and may be useful for evaluation while allowing for the effect of maximal grip strength. The controlled force exertion test measures a somewhat different ability than that measured by the explosive grip test in the non-dominant hand.}, pages = {9--18}, title = {指標追従による筋力発揮調整能と瞬発握力測定値の関係}, volume = {9}, year = {2008} }
