Abstract

Seventeen male adults were tested for static maximal voluntary contraction (MVC) strengths for two-handed grips in a snap-type action at 11 different grip widths, ranging from 3.81-16.51 cm in increment of 1.27 cm. The results indicated that the strength was greatest at the smallest grip width and declined linearly with increasing grip width at the rate of 40.2 N/cm; grip width accounted for 55% of the variation in the strengths; two-handed strength was about 150% as strong as one-handed power grip strength; and the strength-width trend for two-handed gripping was similar to those for one-handed gripping and pinching at widths above approximately 6.4 cm but was different below 6.4 cm. The two-handed strength results in this study are compared to those found in a similar study among females in a previous study.

Relevance to industry: This study provides data on male grip strengths that may be used for evaluating tasks that require two-handed gripping, designing handtools and handles for two-handed gripping, and comparing strength requirements for one- and two-handed manual tasks, with limitations in scope.
