Popis:	Although adequate hip extension strength is necessary for the successful performance of weight-bearing activities, practical quantitative procedures for measuring hip extension strength are lacking. We sought, therefore, to describe a practical procedure and the reliability and validity of measurements obtained with it. Apparently healthy individuals (10 men, 10 women) of 18–27 years participated. One male and one female examiner tested all subjects in supine with a hand-held dynamometer during 2 sessions, 1 week apart. Inter-tester and test-retest reliability of measurements were good to excellent (intraclass correlation coefficients = 0.827–0.949). Known groups validity was supported by a demonstration of significant differences in the strength of men and women participants. Based on the findings of this study we can recommend the procedure for testing with other
