GENDER DIFFERENCES IN KNEE EXTENSOR AND FLEXOR PERFORMANCE
Keywords:strength, torque power, rate of force development, sex differences
AbstractThe purpose of this study was to evaluate gender differences in peak torque (PT), rate of torque development (RTD), power, and work during isometric (ISOM) knee extension and isokinetic (ISOK) knee extension and flexion. Forty-four university women and men volunteered to perform the test exercises on a computerized dynamometer. Data were reduced with manufacturer software and were analyzed with an independent-samples t-test in order to determine gender differences. Results revealed significant differences (P ≤ 0.001) for ISOM PT and ISOK PT, RTD, power, and work. Gender differences in knee extensor and flexor performance are present, with women demonstrating a range of 68.9 to 76.9% of their male counterparts. Conversely, the rate of force production is not gender specific during ISOM knee extension.
