Measurement of handgrip force of the dominant hand at pre-selected force levels for males

An experiment was conducted to measure the grip force of twenty male subjects under guided-gripping scenario. The subjects were instructed to grip with an exertion level of 20%, 50%, 70%, and 100% of their maximum voluntary contraction of their dominant hands. A linear regression model was established to describe the relationship between the gripping force and the rating of Borg´s CR-10 scale. This model was statistically significant at p<;0.0001 and with an R² of 0.9. The Pearson´s correlation coefficient between the grip force and the score of the CR-10 scale was 0.9. The results of this study showed that the guided grip force of the dominant hand of the male subjects had linear relationship with the rating of CR-10 scale. Therefore, the CR-10 scale is appropriate as a quantitative measure of perceived hand grip exertion of the dominant hand for males.
