Background. Previous research has indicated a strong relationship between anthropometric dimensions and strength in males. To date, little work has been done to explore this topic in females. The purpose of this study was to determine the relationships between selected anthropometric dimensions and 1-RM bench press in untrained college females.
Methods. Untrained college females (n=113) were evaluated for 18 measured and seven derived anthropometric variables to predict 1-RM bench press strength. Triplicate measurements were averaged for five skinfolds, five circumferences, and six skeletal widths. Derived measurements included Body Mass Index, percent fat, fat-free mass (FFM), flexed arm cross-sectional area (CSA), shoulder width: hip width ratio, androgyny index, and somatotype.
Results. Highest zero-order correlations with bench press were arm CSA (r=0.45), flexed arm circumference (r=0.45), mesomorphy (r=0.44), and forearm circumference (r=0.42). First-order partial correlations holding constant body mass or FFM generally decreased most correlations with bench press (r<0.30). Factor loadings were used to produce muscle, length, and fat components which were placed in a multiple regression analysis to predict bench press but resulted in only limited success (R=0.58, SEE=±5.6 kg). Coefficients of variation (SEE/Mean ×100) for the equations ranged from was 18.9% to 21.0%.
Conclusions. Prediction of bench press strength from anthropometric dimensions does not appear to be practical or accurate in untrained females.
