Abstract: 
The purpose of the study was to examine velocity-specific composite leg extension and flexion torque of adult participants, using allometric modeling. Seventeen men (25.()y, 1.73m & 63.6kg)
and 15 women (22.5y, 1.oom & 51.1 kg) participated in the study. Peak concentric isokinetic leg extension and flexion torque at 1.05, 3.14, and 5.20 rad/s were determined using a Cybex 6CXX) isokinetic dynamometer. Composite concentnc isoklnetic torque (CClT) O.e. sum of peak extension and flexion torque) generated at 1.05 rad/s was 1.87-1.69 times that at 5.20 rad/s for men and women, respectively. CCiT in Nm in women were 59-65% that of men, but increased to 73-81% and 71-81% that of men when the data were ratio-scaled to body mass (BM) and allometrically-scaled to BM"'l79. 119 & 105, respectively. Common identified b exponents for men and women between CCIT and BM included b=1.0 for torque as predicted by geometric similarity theory, but sample specific derived b exponents are recommended in order to accurately compute body size-free power function ratios.
