The objective of this study was to examine the reliability of thigh muscle strength measurements in healthy preadolescent girls and establish baseline strength data for this population. We utilized a test-retest design. Knee flexor and extensor torques were measured on Kinetic communicator (Kin-Com) isokinetic dynamometers and repeated within 2 weeks in 31 girls. Comparisons were made of peak torques for test-retest, dominant and nondominant limbs, and eccentric versus concentric contractions. Our results indicate eccentric torques were significantly greater than concentric. The test-retest data showed significant differences of 0.41-0.79 for all measurements undertaken. In conclusion, Kin-Com isokinetic dynamometers are moderately reliable in the preadolescent female age group. This is the lower limit of usefulness for these machines. Verf.-Referat
