Experimental study on gender differences in hands and sequence of force application on grip and hand-grip control.

The purpose of this study was to examine how gender of young adults in Taiwan affected the ability of their hands to apply force regarding the use of the left or right hand and the varying sequences of force application. Maximal voluntary contraction of grip (MVCg ) and hand-grip control (HGC 50% ) of 200 participants was measured. The study discovered that gender showed significant differences in the scale of MVC g, whereas there were no significant differences in HGC 50% . Left hand versus right hand resulted in significant differences in the scale of MVC g, whereas there were no significant differences in the scale of HGC 50% . The 5 levels of the sequence of force application showed no significant differences in either MVC g or HGC 50% . The interactive effects of the 3 factors (gender, hand, and sequence of force application) showed no significant differences. The results of the study can serve as a reference in designing tools.
