Prediction of Isometric Grip Strength in College Men and Women

Isometric grip strength (IGS) has been shown to reflect total body strength in both men and women. While it is simple to measure with a dynamometer, some facilities may not have instruments to perform the measurement. The purpose of this study was to determine the accuracy of an IGS prediction equation for men and women. College men (n = 144) and women (n = 155) were measured for height, weight, BMI, forearm cross-sectional area (CSA), and IGS. In a validation sample (n = 240), sex and CSA were selected by multiple regression to predict IGS (R = 0.87, SEE = 6.7 kg). Cross-validation of the equation (n = 59) resulted in a nonsignificant difference between predicted (44.7 ± 11.6 kg) and actual IGS (44.8 ± 13.6), and a strong correlation (r = 0.83) between the two. Muscle CSA may provide an accurate prediction of IGS in men and women.
