The Relationship of Isometric Grip Strength, Optimal Dynamometer Settings, and Certain Anthropometric Factors

Abstract

A study was conducted to determine (a) the relationships between isometric grip strength and eight anthropometric dimensions of the upper extremity, (b) the relationship between isometric grip strength and handle position of the Jamar dynamometer, and (c) a means of predicting optimal positioning of the Jamar dynamometer handle. Measurements were taken from 30 females between the ages of 21 and 25. Data were analyzed by means of the Pearson product-moment correlation, ANOVA and multiple ANOVA, predictive discrimination, and multiple regression. Significant correlations (p < .05) existed between all dimensions of the hand and grip strength in all handle positions except the smallest, ranging from .36 to .61. Analysis of variance demonstrated significant differences between strength at the different handle positions. The results support the use of position two or three of the Jamar dynamometer handle for testing of maximum grip strength. Specific adjustment of the dynamometer handle seems unnecessary, but if desired it should be based upon hand length or length of the long digit. No anthropometric dimension appears to be strong enough to predict grip strength.
