Normative reference values for hand grip dynamometry in Spain. Association with lean mass.

Abstract

The objective of this study was to establish reference values for hand grip strength, compare the results obtained with Collin and Jamar type dynamometers and determine their association with anthropometric and lean mass measurements. This cross-sectional population-based study was undertaken in Pizarra (Málaga, Spain). The grip strength of the dominant hand was measured using Collin and Jamar dynamometers. Skinfolds (triceps, abdominal, biceps of dominant arm and subscapular) were measured, and body composition was estimated. Eight hundred seventeen adults randomly selected from the census were recruited. Dynamometry reference values are presented for the dominant hand, by gender and age groups. No determinations could be made with the Collin dynamometer in 69 women due to the difficulty in grasping the dynamometer. We found significant positive correlations between the measurements with Jamar and Collin dynamometers (r = 0.782; p Dynamometry reference values in the Spanish population are presented. We recommend the use of the Jamar type dynamometer versus the Collin type dynamometer. Hand grip dynamometry is associated with lean mass, which confirms its usefulness in nutritional assessment.
