The ability of anthropometric variables to predict the strength of 42 powerlifters in a relatively simple bench press (BP) and complex squat (SQ) exercise was assessed. Powerlifters were measured for 42 anthropometric dimensions using International Society for the Advancement of Kinanthropometry protocols. Correlation and multiple linear regression analyses were performed, with independent variables entered in stepwise order. The prediction of bench press strength (r = 0.71; SEE = 20 kg; CV = 14%) by flexed upper arm girth and arm length-height index appeared somewhat greater than the prediction of SQ strength (r2 = 0.49, SEE = 33.4 kg, CV = 17%) by musculoskeletal size. These results suggest that the ability of anthropometric measures to predict strength may decrease with exercise complexity in well-trained strength athletes and that anthropometric characteristics place upper limits on BP and SQ strength.
